"Dynein light chain 1, a p21-activated kinase 1-interacting substrate, promotes cancerous phenotypes. \nWe identified dynein light chain 1 (DLC1) as a physiologic substrate of p21-activated kinase 1 (Pak1). Pak1-DLC1 interaction plays an essential role in cell survival, which depends on Pak1's phosphorylation of DLC1 on Ser88. Pak1 associates with the complex of DLC1 and BimL, a proapoptotic BH3-only protein, and phosphorylates both proteins. Phosphorylation of BimL by Pak1 prevents it from interacting with and inactivation of Bcl-2, an antiapoptotic protein. Overexpression of DLC1 but not DLC1-Ser88Ala mutant promotes cancerous properties of breast cancer cells. DLC1 protein level is elevated in more than 90% of human breast tumors. The regulation of cell survival functions by Pak1-DLC1 interaction represents a novel mechanism by which a signaling kinase might regulate the cancerous phenotypes.\n"

"TEL, a putative tumor suppressor, modulates cell growth and cell morphology of ras-transformed cells while repressing the transcription of stromelysin-1. \nTEL is a member of the ETS family of transcription factors that interacts with the mSin3 and SMRT corepressors to regulate transcription. TEL is biallelically disrupted in acute leukemia, and loss of heterozygosity at the TEL locus has been observed in various cancers. Here we show that expression of TEL in Ras-transformed NIH 3T3 cells inhibits cell growth in soft agar and in normal cultures. Unexpectedly, cells expressing both Ras and TEL grew as aggregates. To begin to explain the morphology of Ras-plus TEL-expressing cells, we demonstrated that the endogenous matrix metalloproteinase stromelysin-1 was repressed by TEL. TEL bound sequences in the stromelysin-1 promoter and repressed the promoter in transient-expression assays, suggesting that it is a direct target for TEL-mediated regulation. Mutants of TEL that removed a binding site for the mSin3A corepressor but retained the ETS domain failed to repress stromelysin-1. When BB-94, a matrix metalloproteinase inhibitor, was added to the culture medium of Ras-expressing cells, it caused a cell aggregation phenotype similar to that caused by TEL expression. In addition, TEL inhibited the invasiveness of Ras-transformed cells in vitro and in vivo. Our results suggest that TEL acts as a tumor suppressor, in part, by transcriptional repression of stromelysin-1.\n"

"Regulation of transforming growth factor-beta signaling and vascular diseases.\nPURPOSE: Members of the transforming growth factor (TGF)-beta superfamily play critical roles in regulation of various cellular functions. Dysregulation of the signaling mechanisms of the TGF-beta superfamily proteins is associated with clinical diseases such as cancer, fibrotic diseases, and vascular disorders. Therefore, understanding these signaling mechanisms may provide us with novel ways to develop strategies for treating clinical diseases induced by these cytokines. METHODS: This review discusses our current understanding of the mechanisms of TGF-beta signaling, focusing on the roles of TGF-beta in regulation of vascular wall cells and on the regulation of TGF-beta superfamily signals by inhibitory Smads.\n"

"Conclusions and policy implications\nEarly postnatal home visit is one strategy for providing critical interventions to improve newborn survival. Given the compelling data in this study, we recommend that in developing countries, especially those where home delivery with unskilled attendants is the norm, all newborns should receive a home visit and undergo assessment by a trained worker as soon as possible, preferably on the day of birth but no later than 48 hours after birth. The impact of this approach is likely to be dependent on the content, quality, and coverage of the technical interventions included. Reaching neonates within first day or first two days of life is a challenge. Given that the community health workers in this study were not skilled birth attendants and attended only about 5% of deliveries, a complementary strategy will be to ensure skilled attendance at delivery that is linked to essential obstetric care.31 32 Further operational research will be needed to develop context specific strategies to reach all newborns as soon as possible after birth.\n\n"

"1. Background\nThe United Republic of Tanzania, is among the many countries in sub-Saharan Africa facing a human resources crisis in its health sector, with a small and inequitably distributed health workforce [1] that shoulders a disproportionately high burden of disease[2]. Although all poor countries in the world face a severe human resource crisis in their health sectors [3,4], the problem is most acute in Sub-Saharan Africa, in which an estimated workforce of 750 000 health workers in the region serves 682 million people [2]. By comparison, the ratio is 10 to 15 times higher in developed countries. Moreover, this estimated workforce of doctors, nurses and allied health workers in Sub-Saharan Africa constitutes 1.3% of the world's health workforce, while Africa suffers from 25% of the world's burden of disease [2].\nA minimum level of a health workforce of 2.5 health workers per 1000 people is required to achieve the Millennium Development Goals [5]. Africa is far from this level with a health workforce density that only averages 0.8 worker per 1000 people, while the world median density of health personnel is 5 per 1000 people [5].\nThere is a positive correlation between health worker density and various health indices, most notably infant mortality rate, maternal mortality rates, and various disease specific mortality and morbidity rates [6,7]. An increase in the number of health workers per capita is associated with a notable decline in the rates mentioned above. As a consequence, it has been argued that health worker shortages have impeded the implementation of development goals in many poor countries [8].\n\n"

"Domain 5 of cleaved high molecular weight kininogen inhibits endothelial cell migration through Akt.\nDomain 5 (D5) of cleaved high molecular weight kininogen (HKa) inhibits angiogenesis in vivo and endothelial cell migration in vitro, but the cell signaling pathways involved in HKa and D5 inhibition of endothelial cell migration are incompletely delineated. This study examines the mechanism of HKa and D5 inhibition of two potent stimulators of endothelial cell migration, sphingosine 1-phosphate (S1P) and vascular endothelial growth factor (VEGF), that act through the P13-kinase-Akt signaling pathway. HKa and D5 inhibit bovine pulmonary artery endothelial cell (BPAE) or human umbilical vein endothelial cell chemotaxis in the modified-Boyden chamber in response toVEGF or S1P. The inhibition of migration by HKa is reversed by antibodies to urokinase-type plasminogen activator receptor. Both HKa and D5 decrease the speed of BPAE cell migration and alter the morphology in live, time-lapse microscopy after stimulation with S1P or VEGF. HKa and D5 reduce the localization of paxillin to the focal adhesions after S1P and VEGF stimulation. To better understand the intracellular signaling pathways, we examined the effect of HKa on the phosphorylation of Akt and its downstream effector, GSK-3alpha HKa and D5 inhibit phosphorylation of Akt and GSK-3alpha after stimulation withVEGF and S1P. Inhibitors of Akt and P13-kinase, the upstream activator of Akt, block endothelial cell migration and disrupt paxillin localization to the focal adhesions after stimulation with VEGF and S1P. Therefore we suggest that HKa through its D5 domain alters P13-kinase-Akt signaling to inhibit endothelial cell migration through alterations in the focal adhesions.\n"

"RNA damage and inhibition of neoplastic endothelial cell growth: effects of human and amphibian ribonucleases.\nAngiogenesis defines the many steps involved in the growth and migration of endothelial cell-derived blood vessels. This process is necessary for the growth and metastasis of tumors, and considerable effort is being expended to find inhibitors of tumor angiogenesis. This usually involves screening of potential anti-angiogenic compounds on endothelial cells. To this end, two candidate anti-angiogenic RNA-damaging agents, onconase and (-4)rhEDN, were screened for their effects on endothelial cell proliferation using three distinct types of endothelial cells in culture: HPV-16 E6/E7-immortalized human umbilical vein endothelial cells (HUVECs), a Kras-transformed HPV-16 E6/E7 HUVEC (Rhim et al., Carcinogenesis 4, 673-681, 1998), and primary HUVECs. Onconase similarly inhibited proliferation in all three cell lines (IC(50) = 0.3-1.0 microM) while (-4)rhEDN was more effective on immortalized HUVEC cell lines (IC(50) = 0.02-0.06 microM) than on primary HUVECs (IC(50) > 0.1 microM). Differential sensitivity to these agents implies that more than one endothelial cell type must be used in proliferation assays to screen for novel anti-angiogenic compounds.\n"

"Arteriogenesis: the development and growth of collateral arteries.\nIn patients with atherosclerotic vascular diseases, collateral vessels bypassing major arterial obstructions have frequently been observed. This may explain why some patients remain without symptoms or signs of ischemia. The term \"arteriogenesis\" was introduced to differentiate the formation of collateral arteries from angiogenesis, which mainly occurs in the ischemic, collateral flow-dependent tissue. Many observations in various animal models and humans support that the remodeling of preexisting collateral vessels is the mechanism of collateral artery formation. This remodeling process seems to be mainly flow-mediated. It involves endothelial cell activation, basal membrane degradation, leukocyte invasion, proliferation of vascular cells, neointima formation (in most species studied), and changes of the extracellular matrix. The contribution of ischemia to arteriogenesis is still unclear, but arteriogenesis clearly can occur in the absence of any significant ischemia. It is questionable, whether collateral arteries also form de novo in ischemic vascular diseases. A better understanding of the mechanisms of arteriogenesis will be important for the design of more effective strategies for the treatment of patients with ischemic vascular diseases.\n"

"Role of stromal myofibroblasts in invasive breast cancer: stromal expression of alpha-smooth muscle actin correlates with worse clinical outcome. \nBACKGROUND: Recently, the desmoplastic reaction has been implicated as having an important function in epithelial solid tumor biology. There have been no reports showing the relativity of invasive breast cancer and the desmoplastic reaction by a quantitative analysis of the myofibroblasts that were an important player in the desmoplastic reaction. The purpose of this study was to immunohistochemically investigate the correlation between the desmoplastic reaction and the clinicopathology of invasive breast cancer. METHODS: The study included 60 patients with a known prognosis of invasive breast cancer. We quantified the expression of alpha-SMA as a marker of myofibroblasts in the invasive breast cancer. After staining samples for alpha-SMA, their expression was extracted and quantified as a relative percentage by computer-assisted image analysis. RESULTS: There was relatively wide variation in the expression of alpha-SMA with the percentage of the area from 0.68 to 28.15% (mean 8.48 +/- 5.40%). The metastasis group showed significantly higher alpha-SMA expression compared with the no metastasis group (p < 0.001). When the patients were divided into two groups according to their alpha-SMA expression using a cutoff point at the mean value of 8.48%, the high alpha-SMA group had a significantly poorer overall survival rate (p < 0.001). Multivariate analysis demonstrated that alpha-SMA and lymph node metastasis were identified as independent predictive factors of metastasis. CONCLUSION: Myofibroblasts represent an important prognostic factor for invasive growth that is translated into a poor clinical prognosis for patients with invasive breast cancer.\n"

"Enhancement of skin permeation of ketotifen by supersaturation generated by amorphous form of the drug.\nPressure sensitive adhesive (PSA) matrices containing amorphous ketotifen were prepared and evaluated for enhanced skin permeability of the drug. A solvent casting method using silicone-typed PSA was employed, and n-hexane, an original solvent for the PSA and one more solvent, dichloromethane, tetrahydrofuran, acetone, ethyl acetate or toluene, were used for complete dissolution of ketotifen and high dispersion in an amorphous state of the drug. Presence of the amorphous form was judged based on the in vitro drug release rate from the matrix. As a result, dichloromethane and tetrahudrofuran were selected as appropriate dilution solvents. In vitro permeation experiments through excised hairless mouse skin revealed that the steady-state flux from the amorphous ketotifen-dispersed matrices was about five times greater than that of the crystalline ketotifen-dispersed matrices, and that the enhancement ratio was in good agreement with the solubility ratio of the amorphous to crystalline form of the drug. Comparison of the skin permeation profiles of amorphous ketotifen-dispersed matrices between two different drug contents suggested that the steady-state flux was not influenced by the drug content. In addition, at both drug contents, the period of the steady-state permeation coincided with the time until the amorphous drug was depleted from the matrix. These results suggest that the increase in skin permeation of ketotifen from PSA matrix was due to the supersaturation generated by amorphous form, and that the amorphous form was stable during the application period.\n"

"The inhibition of cultured myoblast differentiation by the simian virus 40 large T antigen occurs after myogenin expression and Rb up-regulation and is not exerted by transformation-competent cytoplasmic mutants. \nWe have investigated the mechanism by which the simian virus 40 large T antigen (SVLT) interferes with the differentiation of C2 myoblasts. SVLT mutants, defective either in the Rb binding site, near the N-terminal end, in a region that affects binding to p53, or in the nuclear transport signal, were also employed to determine whether the interference was especially dependent on these functional domains. It was found that wild-type (wt) SVLT strongly inhibited the terminal differentiation of mouse C2 myoblasts, but this arrest occurred only after the synthesis of myogenin, an initial step in biochemical differentiation. Neither the synthesis nor some basic activities of MyoD appeared to be affected by wt SVLT. In these transformants, mitogen depletion elicited an increase in the Rb level comparable to that in normal C2 cells; wt SVLT, however, promoted the phosphorylation of a large part of the induced Rb. Mutations affecting nuclear transport were far more critical for the ability to interfere with myogenic differentiation than were those affecting the transforming potential; cytoplasmic SVLT expression was fully compatible with the terminal differentiation of C2 cells, despite enabling them to grow in semisolid medium, thus showing that the myogenesis-inhibiting property can be dissociated from transforming competence. The remaining SVLT mutants presented different degrees of ability to inhibit differentiation (as shown by the expression of tissue-specific markers in transformants). The inhibiting mutants, including the Rb binding site mutant, were able to promote a higher state of Rb phosphorylation than that observed in either normal cells or cytoplasmic-SVLT transformants.\n"

"An antibody directed against PDGF receptor beta enhances the antitumor and the anti-angiogenic activities of an anti-VEGF receptor 2 antibody.\nPlatelet-derived growth factor (PDGF) and its receptors (PDGFR) play important roles in tumorigenesis through stimulating tumor growth and promoting angiogenesis via enhancing pericyte recruitment and vessel maturation. Here we produced a neutralizing antibody, 1B3, directed against mouse PDGFRbeta. 1B3 binds to PDGFRbeta with high affinity (9x10(-11)M) and blocks PDGF-BB from binding to the receptor with an IC(50) of approximately 1.2 nM. The antibody also blocks ligand-stimulated activation of PDGFRbeta and downstream signaling molecules, including Akt and MAPK p42/44, in tumor cells. In animal studies, 1B3 significantly enhanced the antitumor and the anti-angiogenic activities of DC101, an antibody directed against mouse vascular endothelial growth factor receptor 2, in a pancreatic (BxPC-3) and a non-small cell lung (NCI-H460) tumor xenograft models. Treatment with the combination of 1B3 and DC101 in BxPC-3 xenograft-bearing mice resulted in tumor regression in 58% of mice compared to that in 18% of mice treated with DC101 alone. Taken together, these results lend great support to use PDGFRbeta antagonists in combinations with other antitumor and/or anti-angiogenic agents in the treatment of a variety of cancers.\n"

"Characterization of the metabolic changes underlying growth factor angiogenic activation: identification of new potential therapeutic targets.\nAngiogenesis is a fundamental process to normal and abnormal tissue growth and repair, which consists of recruiting endothelial cells toward an angiogenic stimulus. The cells subsequently proliferate and differentiate to form endothelial tubes and capillary-like structures. Little is known about the metabolic adaptation of endothelial cells through such a transformation. We studied the metabolic changes of endothelial cell activation by growth factors using human umbilical vein endothelial cells (HUVECs), [1,2-(13)C(2)]-glucose and mass isotopomer distribution analysis. The metabolism of [1,2-(13)C(2)]-glucose by HUVEC allows us to trace many of the main glucose metabolic pathways, including glycogen synthesis, the pentose cycle and the glycolytic pathways. So we established that these pathways were crucial to endothelial cell proliferation under vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF) stimulation. A specific VEGF receptor-2 inhibitor demonstrated the importance of glycogen metabolism and pentose cycle pathway. Furthermore, we showed that glycogen was depleted in a low glucose medium, but conserved under hypoxic conditions. Finally, we demonstrated that direct inhibition of key enzymes to glycogen metabolism and pentose phosphate pathways reduced HUVEC viability and migration. In this regard, inhibitors of these pathways have been shown to be effective antitumoral agents. To sum up, our data suggest that the inhibition of metabolic pathways offers a novel and powerful therapeutic approach, which simultaneously inhibits tumor cell proliferation and tumor-induced angiogenesis.\n"

"The antiangiogenic agent linomide inhibits the growth rate of von Hippel-Lindau paraganglioma xenografts to mice.\nThe aim of this study was to ascertain the potential usefulness of the antiangiogenic compound linomide for treatment of von Hippel-Lindau (VHL)-related tumors. Paraganglioma tissue fragments obtained at surgery from a VHL type 2a patient were transplanted s.c. to male BALB/c nu/nu (nude) mice: (a) 2-3-mm fragments for \"prevention\" experiments; and (b) 2-3-mm fragments allowed to grow to 1 cm for \"intervention\" studies. Both groups received either 0.5 mg/ml linomide in drinking water or acidified water and were followed until tumor diameter reached 3 cm or for 4 weeks. In both the prevention and intervention experiments, a significant diminution of tumor size and weight was observed in the drug-treated animals. In vivo nuclear magnetic resonance analysis of tumor blood flow in linomide-treated animals showed localization of blood vessels almost exclusively to the periphery of the poorly vascularized tumors with a significant reduction of both vascular functionality and vasodilation. Histological examination of tumors from linomide-treated animals revealed marked avascularity. Treated animals also displayed a 2.4-fold reduction of tumor vascular endothelial growth factor mRNA levels. Taken together, our data indicate that in VHL disease, therapy directed at inhibition of constitutively expressed VEGF induction of angiogenesis by VHL tumors may constitute an effective medical treatment.\n"

"Optimizing treatment of choroidal neovascularization feeder vessels associated with age-related macular degeneration.\nPURPOSE: To optimize the method of treating choroidal neovascularization (CNV) associated with age-related macular degeneration (AMD). DESIGN: Experimental study and interventional case series. METHODS: The parameters associated with locating and then photocoagulating CNV feeder vessels were identified and optimized using published data and data derived from modeling the choroidal vasculature. Based on these optimized parameters, a prototype diagnostic/treatment system was designed that captures high-speed indocyanine green (ICG) angiogram images and facilitates analysis of the images by enhancing visualization of dye movement through CNV feeder vessels (FVs). The system also permits precise aiming and delivery of 810- nm wavelength photocoagulation laser energy to target FVs on a real-time ICG angiogram image of the choroidal vasculature. Target FVs are tracked by a joy-stick controlled laser aiming beam until an intravenously-injected high-concentration ICG dye bolus is observed to enter the target vessel, at which time the laser is fired. Proof of principle of the combined diagnosis/treatment system design for performing dye-enhanced photocoagulation (DEP) in the clinical setting and determination of the minimum DEP laser energy needed to close CNV FVs was made in 11 AMD patients requiring treatment of CNV, but for whom other treatment was not appropriate. RESULTS: Using ICG-DEP, CNV feeder vessels were closed with single pulse laser energy, delivering as little as 0.6 to 1.8 J of energy to the fundus, producing no visible change in the fundus. Successful FV closure was usually indicated immediately by presence of incarcerated ICG dye in the vessel adjacent to the burn site. The prototype system proved relatively easy to operate. After acquiring and interpreting diagnostic angiograms and repositioning a patient in front of the device, feeder vessel DEP and treatment evaluation required 15 to 20 minutes. CONCLUSIONS: Indocyanine green dye-enhanced photocoagulation of CNV feeder vessels, facilitated by use of a device that permits real-time visualization of the choroidal circulation while aiming the treatment laser beam, appears to minimize the amount of energy applied to the fundus and the volume of fundus tissue affected by treatment, compared with other treatment modalities. The combination diagnosis/treatment device should be useful in optimizing FV treatment and in refining and evaluating the efficacy of DEP in future clinical trials.\n"

"IL-12 inhibition of endothelial cell functions and angiogenesis depends on lymphocyte-endothelial cell cross-talk.\nIn vivo IL-12-dependent tumor inhibition rests on the ability of IL-12 to activate a CD8-mediated cytotoxicity, inhibit angiogenesis, and cause vascular injury. Although in vivo studies have shown that such inhibition stems from complex interactions of immune cells and the production of IFN-gamma and other downstream angiostatic chemokines, the mechanisms involved are still poorly defined. Here we show that IL-12 activates an anti-angiogenic program in Con A-activated mouse spleen cells (activated spc) or human PBMC (activated PBMC). The soluble factors they release in its presence arrest the cycle of endothelial cells (EC), inhibit in vitro angiogenesis, negatively modulate the production of matrix metalloproteinase-9, and the ability of EC to adhere to vitronectin and up-regulate ICAM-1 and VCAM-1 expression. These effects do not require direct cell-cell contact, yet result from continuous interaction between activated lymphoid cells and EC. We used neutralizing Abs to show that the IFN-inducible protein-10 and monokine-induced by IFN-gamma chemokines are pivotal in inducing these effects. Experiments with nu/nu mice, nonobese diabetic-SCID mice, or activated spc enriched in specific cell subpopulations demonstrated that CD4(+), CD8(+), and NK cells are all needed to mediate the full anti-angiogenetic effect of IL-12.\n"

"Effect of thalidomide affecting VEGF secretion, cell migration, adhesion and capillary tube formation of human endothelial EA.hy 926 cells.\nAngiogenesis, new blood vessel formation, is a multistep process, precisely regulated by pro-angiogenic cytokines, which stimulate endothelial cells to migrate, proliferate and differentiate to form new capillary microvessels. Excessive vascular development and blood vessel remodeling appears in psoriasis, rheumatoid arthritis, diabetic retinopathy and solid tumors formation. Thalidomide [alpha-(N-phthalimido)-glutarimide] is known to be a potent inhibitor of angiogenesis, but the mechanism of its inhibitory action remains unclear. The aim of the study was to investigate the potential influence of thalidomide on the several steps of angiogenesis, using in vitro models. We have evaluated the effect of thalidomide on VEGF secretion, cell migration, adhesion as well as in capillary formation of human endothelial cell line EA.hy 926. Thalidomide at the concentrations of 0.01 microM and 10 microM inhibited VEGF secretion into supernatants, decreased the number of formed capillary tubes and increased cell adhesion to collagen. Administration of thalidomide at the concentration of 0.01 microM increased cell migration, while at 10 microM, it decreased cell migration. Thalidomide in concentrations from 0.1 microM to 10 microM did not change cell proliferation of 72-h cell cultures. We conclude that anti-angiogenic action of thalidomide is due to direct inhibitory action on VEGF secretion and capillary microvessel formation as well as immunomodulatory influence on EA.hy 926 cells migration and adhesion.\n"

"[Uncommon etiology of gastrointestinal bleeding: duodenal metastases from renal cell carcinoma].\nBecause of its unpredictable behavior, renal cell carcinoma is one of the most controversial neoplasms. On the one hand, patients frequently show metastases at diagnosis because of its slight manifestations, while on the other, the neoplasm can remain stable after nephrectomy and can then metastasize many years later. When this happens, the metastases usually involve more than 2 organs. The most frequent sites of metastases are the lung and lymph nodes, followed by the bones and liver, while duodenal involvement is rare. Indeed, intestinal metastases are found in only 2% of autopsies and of these, renal cell carcinoma metastases account for 7.1%. We present a case of a solitary late recurrence presenting as upper gastrointestinal bleeding 19 years after nephrectomy for clear cell renal carcinoma.\n"

"Differential mechanisms of radiosensitization by 2-deoxy-D-glucose in the monolayers and multicellular spheroids of a human glioma cell line.\nIn vitro studies using monolayer cultures of human tumor cell lines have shown that 2-DG selectively inhibits energy-dependent DNA repair and cellular recovery processes in cancer cells. However, monolayer cultures differ greatly from the complex environmental conditions generated in solid tumors that develop inhomogeneous hypoxic and necrotic regions. In contrast, multicellular spheroids mimic heterogeneous cellular behavior and the consequent functional characteristics of in vivo solid tumors, and serve as important in vitro model to investigate tumor biology and responses to potential therapeutic agents. The present study compares the radiomodification by 2-DG in monolayer cultures and spheroids of a human glioma cell line (BMG-1) to gain insight into the effects in solid tumors. In spheroids, the glucose consumption (2.1 p mole/cell/h) and lactate production (3.67 p mole/cell/h) was nearly 2-3 fold higher than in monolayer cells (0.83 and 1.43 p mole/cell/h respectively). Presence of 2-DG (5 mM) for 2-4 h inhibited the glucose usage and lactate production by 70% in spheroids, while a 35% reduction was observed in monolayer cells. Under these conditions, 2-DG drastically enhanced the radiation-induced cell death of spheroids (by 2-3 folds); while a 40% increase was observed in monolayer cells. Radiosensitization by 2-DG in monolayer cells was primarily due to an increase in mitotic death (23%) linked to cytogenetic damage (micronuclei), whereas a profound induction of apoptosis (40%) accounted for the sensitization in spheroids. Although the Bcl-2 and Bax levels were significantly higher in spheroids, Bcl-2/Bax ratio was similar in monolayers and spheroids. Comet assay revealed a late onset of DNA breaks in the presence of 2- DG following irradiation only in spheroids, which corroborated well with the late onset of oxidative stress. 2-DG did not induce a significant cell cycle delay in monolayers, while a transient G(2) delay was apparent in spheroids.\n"

"Role of thrombogenic factors in the development of atherosclerosis.\nHemostatic factors play a crucial role in generating thrombotic plugs at sites of vascular damage (atherothrombosis). However, whether hemostatic factors contribute directly or indirectly to the pathogenesis of atherosclerosis remains uncertain. Autopsy studies have revealed that intimal thickening represents the first stage of atherosclerosis and that lipid-rich plaque arises from such lesions. Several factors contribute to the start of intimal thickening. Platelets release several growth factors and bioactive agents that play a central role in development of not only thrombus but also of intimal thickening. We have been investigating which coagulation factors simultaneously, or subsequently with platelet aggregation, participate in thrombus formation. Tissue factor (TF) is an essential initiator of blood coagulation that is expressed in various stages of atherosclerotic lesions in humans and other animals. Factors including thrombin and fibrin, which are downstream of the coagulation cascade activated by TF, also contribute to atherosclerosis. TF is involved in cell migration, embryogenesis and angiogenesis. Thus TF, in addition to factors downstream of the coagulation cascade and the protease-activated receptor 2 activation system, would be a multifactorial regulator of atherogenesis.\n"

"Reversal of the malignant phenotype of ovarian cancer A2780 cells through transfection with wild-type PTEN gene. \nOBJECTIVE: PTEN (phosphatase and tensin homologue deleted on chromosome 10) is a tumor suppressor gene identified on human chromosome 10q23. Substantial studies have demonstrated that PTEN can inhibit cell proliferation, migration and invasion of many cancer cells. The purpose of this study was to determine whether upregulation of PTEN gene by transfection wild-type PTEN gene to ovarian cancer cells can inhibit growth and migration and to explore the potential for PTEN gene therapy of ovarian cancers. METHOD: Wild-type and phosphatase-inactive (C124A) PTEN plasmids were transfected into ovarian epithelial cancer A2780 cells, and their effects on cell apoptosis, cell proliferation, cell migration and cell invasion were analyzed by flow cytometry analysis, TUNEL assay, MTT assay, wound-healing assay and transwell assay. RESULTS: Both wild-type and mutant PTEN can upregulate the expression of PTEN gene dramatically; however, it is wild-type PTEN not phosphatase-inactive PTEN that can induce apoptosis and decrease cell migration, invasion and proliferation in ovarian cancer cells. CONCLUSION: These results demonstrated that PTEN had played an important role in the cell proliferation, cell migration and invasion dependent on its phosphatase activity. Enhanced expression of PTEN by gene transfer is sufficient to reverse the malignant phenotype of ovarian cancer cells and transfection of ovarian cancer cells with wild-type PTEN gene might be another novel approach for therapeutic intervention in ovarian cancer.\n"

"Energy supply of the mitotic cell cycle and the Na+/H+-antiport in ascites tumors.\nThe activation of Na+ transport is due to the exchange of protons formed via glucose conversion into lactate for Na+, i.e., to the stimulation of the Na+/H+-antiport. Experimental results and theoretical calculations suggest that in glucose-containing medium the Na+ transport increases from 0.75 to 1.78 pmol/hour per cell. The permeability of plasma membranes for K+ increases 2.75 fold, while the passive flux of Na+ diminishes. The intensity of O2 adsorption by ascites tumor cells does not practically depend on the monovalent cation concentration gradient between the cells and the culture medium, whereas the rate of glycolysis decreases simultaneously with the diminution of the concentration gradient. In synchronized cultures at the beginning of the mitotic cycle, the bulk of ATP resynthesized via glycolysis is utilized for the synthesis of biopolymers, whereas that at the end of the S-phase and in the G2-phase is utilized for cation transport across plasma membranes. From 35 to 100% of the whole amount of ATP resynthesized via glycolysis is utilized for transport purposes. It is concluded that the observed increase in the Na+/K+ ratio in ascites tumor cells is connected with their enhanced ability to synthesize lactic acid. Presumably, glycolysis is one of the regulatory mechanisms of intracellular ratios of monovalent cations.\n"

"Active hair growth (anagen) is associated with angiogenesis.\nAfter the completion of skin development, angiogenesis, i.e., the growth of new capillaries from pre-existing blood vessels, is held to occur in the skin only under pathologic conditions. It has long been noted, however, that hair follicle cycling is associated with prominent changes in skin perfusion, that the epithelial hair bulbs of anagen follicles display angiogenic properties, and that the follicular dermal papilla can produce angiogenic factors. Despite these suggestive observations, no formal proof is as yet available for the concept that angiogenesis is a physiologic event that occurs all over the mature mammalian integument whenever hair follicles switch from resting (telogen) to active growth (anagen). This study uses quantitative histomorphometry and double-immunohistologic detection techniques for the demarcation of proliferating endothelial cells, to show that synchronized hair follicle cycling in adolescent C57BL/6 mice is associated with substantial angiogenesis, and that inhibiting angiogenesis in vivo by the intraperitoneal application of a fumagillin derivative retards experimentally induced anagen development in these mice. Thus, angiogenesis is a physiologic event in normal postnatal murine skin, apparently is dictated by the hair follicle, and appears to be required for normal anagen development. Anagen-associated angiogenesis offers an attractive model for identifying the physiologic controls of cutaneous angiogenesis, and an interesting system for screening the effects of potential antiangiogenic drugs in vivo.\n"

"Discussion\nWe estimated the future acceptability of PrEP, examining the attitudes and preferences of potential user groups from different countries towards hypothetical and known PrEP attributes. Our results show that participants were generally willing to accept PrEP and adopt it as soon as it becomes available. Surprisingly, participants were also willing to take PrEP even when reminded of potential side effects, cost, condom use, and frequent HIV testing. These findings indicate participants' motivation to overcome barriers which can have a considerable impact on uptake. In contrast, participants mentioned that the thought of taking PrEP made them feel anxious, although they also indicated that taking PrEP would not be embarrassing and they would want their partner or partners to know. Participants' anxiety may be explained by the hypothetical nature of most of the presented PrEP characteristics, the stigma associated with HIV [34], and in some settings, the criminalization of sex work, injected drug use and homosexuality [35]. Most participants, nonetheless, subsequently indicated that PrEP would give them hope, which suggests that their initial willingness to take it remained largely unscathed.\nFemale participants indicated a higher level of willingness to take PrEP than male participants, which may be explained by women's difficulty negotiating the use of condoms and awareness of their and/or their partners' risk of becoming infected with HIV [36]. We also found that younger participants and those with fewer children, those who reported adherence to past medication, more frequent condom usage, having been tested for HIV in the past and never injecting drugs, reported greater willingness to take PrEP. These promising findings suggest that those who are currently bearing the brunt of HIV [1], have higher perceived risk, and are most likely to adhere to a comprehensive PrEP program, are also the most motivated to enroll. Yet, while participants stated not being interested in selling PrEP, the majority reported intentions to share it. Therefore, information and counseling about the risks of sharing PrEP should be readily available as part of any implementation program.\nResults from the conjoint analysis reveal trends in participants' preferences which deserve consideration. PrEP route of administration was the most important attribute, and bi-monthly and monthly injections were the preferred alternatives. This finding is encouraging from a policy perspective if such modalities become available; since it may reduce users' likelihood of sharing, selling or forgetting to take PrEP, but it also raises questions regarding participants' willingness to take oral PrEP. HIV testing was the second most important attribute, and a test every six months was, as expected, the preferred alternative. Interestingly, dispensing sites were more important than any other attribute for some groups, particularly in Africa. This may indicate concerns about social stigma and access [37]. However, it is encouraging that most participants were willing to receive PrEP at a healthcare facility, which can facilitate synergies between PrEP and other existing prevention services. Time spent obtaining PrEP and frequency of pick up, which we used as a proxy measure for cost-opportunity, were generally less important, consistent with participants' willingness to pay for PrEP.\nOur findings are broadly consistent with the work of Guest et al. and Galea et al [18], [19]. However, specific comparisons are not advisable as the composition and size of the samples, recruitment methods, measures and statistical analyses differ greatly. Previous work on PrEP implementation suggests that delivery programs will need to meet a number of requirements in order to be effective, including: prioritization of groups at higher risk of infection; delivery of PrEP in combination with other prevention services, including risk reduction and medication adherence counseling, condoms provision, diagnosis and treatment of other sexually transmitted infections, and frequent HIV testing; and monitoring of side effects, adherence and risk behaviors [8], [38], [39], [40], [41], [42]. Our results provide valuable clues that can help countries to deliver PrEP more effectively, should they decide to implement it, by focusing their efforts on the aspects that need more attention.\nThis is the first multinational study, to our knowledge, that integrates different disciplines to shed light on a question that we believe is of global importance. Our study complements previous work on PrEP by examining potential users' perspective and offering insights into their attitudes and preferences. We note that it may not be possible to generalize the observed PrEP acceptability to other settings and our results should be considered within the context of this study's limitations. Given the sensitive nature of the addressed questions, and despite all our efforts to reduce social desirability bias, there is an unavoidable risk that participants may have felt at times compelled to provide what they felt was the \"right\" answer. Additionally, our data collection took place in urban areas, where HIV incidence is normally higher, thus current findings may not be generalizable to rural settings. Finally, examining acceptability among users enrolled in pilot programs is much deserving, as actual acceptability may differ from potential willingness to take PrEP, especially if relevant attributes of a product or program are modified, as observed in other comparable interventions [43].\n\n"

"Angiogenesis associated with visceral and subcutaneous adipose tissue in severe human obesity.\nOBJECTIVE: The expansion of adipose tissue is linked to the development of its vasculature. However, the regulation of adipose tissue angiogenesis in humans has not been extensively studied. Our aim was to compare the angiogenesis associated with subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) from the same obese patients in an in vivo model. RESEARCH DESIGN AND METHODS: Adipose tissue samples from visceral (VAT) and subcutaneous (SAT) sites, obtained from 36 obese patients (mean BMI 46.5 kg/m(2)) during bariatric surgery, were layered on chick chorioallantoic membrane (CAM). RESULTS: Both SAT and VAT expressed angiogenic factors without significant difference for vascular endothelial growth factor (VEGF) expression. Adipose tissue layered on CAM stimulated angiogenesis. Angiogenic stimulation was macroscopically detectable, with engulfment of the samples, in 39% and was evidenced by angiography in 59% of the samples. A connection between CAM and adipose tissue vessels was evidenced by immunohistochemistry, with recruitment of both avian and human endothelial cells. The angiogenic potency of adipose tissue was not related to its localization (with an angiogenic stimulation in 60% of SAT samples and 61% of VAT samples) or to adipocyte size or inflammatory infiltrate assessed in adipose samples before the graft on CAM. Stimulation of angiogenesis by adipose tissue was nearly abolished by bevacizumab, which specifically targets human VEGF. CONCLUSIONS: We have established a model to study the regulation of angiogenesis by human adipose tissue. This model highlighted the role of VEGF in angiogenesis in both SAT and VAT.\n"

"A novel conotoxin from Conus delessertii with posttranslationally modified lysine residues.\nA major peptide, de13a from the crude venom of Conus delessertii collected in the Yucatan Channel, Mexico, was purified. The peptide had a high content of posttranslationally modified amino acids, including 6-bromotryptophan and a nonstandard amino acid that proved to be 5-hydroxylysine. This is the first report of 5-hydroxylysine residues in conotoxins. The sequence analysis, together with cDNA cloning and a mass determination (monoisotopic mass of 3486.76 Da), established that the mature toxin has the sequence DCOTSCOTTCANGWECCKGYOCVNKACSGCTH, where O is 4-hydroxyproline, W 6-bromotryptophan, and K 5-hydroxylysine, the asterisk represents the amidated C-terminus, and the calculated monoisotopic mass is 3487.09 Da. The eight Cys residues are arranged in a pattern (C-C-C-CC-C-C-C) not described previously in conotoxins. This arrangement, for which we propose the designation of framework #13 or XIII, differs from the ones (C-C-CC-CC-C-C and C-C-C-C-CC-C-C) present in other conotoxins which also contain eight Cys residues. This peptide thus defines a novel class of conotoxins, with a new posttranslational modification not previously found in other Conus peptide families.\n"

"Adenovirus 5 E1A enhances histone deacetylase inhibitors-induced apoptosis through Egr-1-mediated Bim upregulation. \nHistone deacetylase inhibitors (HDACi) are potent anti-cancer agents for variety of cancer types. Suberoylanilide hydroxamic acid (SAHA) has been approved as a drug to treat cutaneous T cell lymphoma, and the combination of HDACi and other agents have been actively tested in many clinical trials. Adenovirus 5 early region 1A (E1A) has been shown to exhibit high tumor suppressor activity, and gene therapy using E1A has been tested in clinical trials. Here, we showed that proapoptotic activity of HDACi was robustly enhanced by E1A in multiple cancer cells, but not in normal cells. Moreover, we showed that combination of E1A gene therapy and SAHA showed high therapeutic efficacy with low toxicity in vivo ovarian and breast xenograft models. SAHA downregulated Bcl-XL and upregulated proapoptotic BH3-only protein Bim, whose expression was further enhanced by E1A in cancer cells. These alterations of Bcl-2 family proteins were critical for apoptosis induced by the combination in cancer cells. SAHA enhanced acetylation of histone H3 in Bim promoter region, while E1A upregulated Egr-1, which was directly involved in Bim transactivation. Together, our results provide not only a novel insight into the mechanisms underlying anti-tumor activity of E1A, but also a rationale for the combined HDACi and E1A gene therapy in future clinical trials.\n"

"Prognostic value of p53 protein expression and vascular endothelial growth factor expression in resected squamous cell carcinoma of the esophagus.\nThe most common genetic alterations found in a wide variety of cancers are p53 tumor suppressor gene mutations. p53 appears to be a nuclear transcription factor that plays a role in the control of cell proliferation, apoptosis, and the maintenance of genetic stability. Angiogenesis is a critical process in solid tumor growth and metastasis. Vascular endothelial growth factor (VEGF), a recently identified growth factor with significant angiogenic properties, may be a major tumor angiogenesis regulator. Few studies have investigated the association between p53 and VEGF expressions and prognosis in esophageal carcinoma. Forty-seven specimens resected from patients with stage II and III squamous cell carcinoma (SCC) of the esophagus were studied using immunohistochemical staining. VEGF and p53 expressions were observed in 40% and 53% of the tumors, respectively. The p53 and VEGF staining statuses were coincident in only 21% of the tumors, and no significant correlation was found between p53 and VEGF statuses. No clinicopathologic factors were significantly correlated with p53 or VEGF expression. No significant association between p53 and VEGF expressions and poor prognosis was found. In conclusion, p53 and VEGF were not correlated with prognosis in patients with stage II and III SCC of the esophagus.\n"

"External beam radiotherapy for subretinal neovascularization in age-related macular degeneration: is this treatment efficient?\nPURPOSE: Control of the natural course of subretinal neovascularization (SRNV) in age-related macular degeneration (AMD) is difficult. Only a subset of patients is suitable for laser coagulation. This prospective study aimed to determine the efficacy and individual benefit of external beam radiotherapy (EBRT). METHODS AND MATERIALS: The prospective trial included 287 patients with subfoveal neovascularization due to AMD which was verified by fluorescein angiography. Patients have been treated between January 1996 and October 1997. All patients received a total dose of 16 Gy in 2-Gy daily fractions with 5-6 MeV photons based on computerized treatment planning in individual head mask fixation. This first analysis is based on 73 patients (50 women, 23 men, median age 74.3 years), with a median follow-up of 13.3 months and a minimum follow-up of 11 months. RESULTS: All patients completed therapy and tolerability was good. First clinical control with second angiography was performed 6 weeks after irradiation, then in 3-month intervals. Eighteen patients with SRNV refusing radiotherapy served as a control group and were matched with 18 irradiated patients. After 7 months median visual acuity (VA) was 20/160 for the irradiated and 20/400 for the untreated patients. One year after radiotherapy final median VA was 20/400 in both groups. CONCLUSION: These results suggest that 16 Gy of conventionally fractionated external beam irradiation slows down the visual loss in exudative AMD for only a few months. Patients' reading vision could not be saved for a long-term run.\n"

"Differential effects of carbachol on calcium entry and release in CHO cells expressing the m3 muscarinic receptor.\nCalcium signalling was examined in CHO-k1 cells that stably express the m3 subtype of the muscarinic receptor. The calcium indicator Fura-2 was retained in these cells only in the presence of probenecid (1 mM), suggesting that Fura-2 efflux was mediated by an organic anion transporter. The addition of carbachol (CCh) to Fura-2 loaded cells in suspension caused a rapid transient increase in intracellular calcium [Ca]i followed by a smaller sustained plateau phase. The transient rise in [Ca]i was dose-dependent with a threshold response of 89 +/- 18 nM above baseline with 10 nM CCh and a maximum stimulation of 734 +/- 46 nM with 10 microM CCh. This phase was accompanied by a similar dose-dependent stimulation of total inositol phosphate production and was assumed to be generated by release from intracellular stores of the endoplasmic reticulum (ER). The sustained increase in [Ca]i was generated by entry from the extracellular bath since it was blocked by pretreatment with La3+ (1 microM) and was absent when bath calcium was chelated with EGTA. This phase was not dependent on CCh dose, and a stimulation of [Ca]i of approximately 90 nM above baseline was observed with CCh concentrations between 50 nM and 10 microM. With this dose range, the rate of Mn2+ quenching of Fura-2 at the Ca-insensitive excitation wavelength of 360 nm was likewise maximally stimulated. At lower CCh concentrations (10-50 nM), it was clear that the activation of Ca entry could not be dissociated from a threshold release of Ca from intracellular stores. The phorbol ester PMA, which uncouples the muscarinic receptor from phospholipase C, reduced the transient rise in [Ca]i by approximately 50% with little or no effect on Ca entry at higher CCh levels (> or = 1 microM). At lower CCh concentrations (< or = 100 nM) however, pretreatment with PMA completely blocked all Ca mobilization and supports the contention that Ca entry is coupled to Ca release from stores or to store depletion. The emptying of inositol trisphosphate-sensitive stores with thapsigargin (10 nM) stimulated Ca entry and also the rate of Mn2+ quenching. Store depletion by incubation in Ca-free media likewise stimulated Mn2+ uptake without a rise in [Ca]i. Our data are therefore consistent with a 'capacitative' coupling model, whereby the activation of the plasma membrane receptor leads to an InsP3-induced change in the degree of filling of the ER Ca pool.(ABSTRACT TRUNCATED AT 400 WORDS)\n"

"Novel insights into the pathogenesis of uric acid nephrolithiasis.\nPURPOSE OF REVIEW:\nThe factors involved in the pathogenesis of uric acid nephrolithiasis are well known. A low urinary pH is the most significant element in the generation of stones, with hyperuricosuria being a less common finding. The underlying mechanism(s) responsible for these disturbances remain poorly characterized. This review summarizes previous knowledge and highlights some recent developments in the pathophysiology of low urine pH and hyperuricosuria.\nRECENT FINDINGS:\nEpidemiological and metabolic studies have indicated an association between uric acid nephrolithiasis and insulin resistance. Some potential mechanisms include impaired ammoniagenesis caused by resistance to insulin action in the renal proximal tubule, or substrate competition by free fatty acids. The evaluation of a large Sicilian kindred recently revealed a putative genetic locus linked to uric acid stone disease. The identification of novel complementary DNA has provided an interesting insight into the renal handling of uric acid, including one genetic cause of renal uric acid wasting.\nSUMMARY:\nThe recognition of metabolic, molecular, and genetic factors that influence urinary pH, and uric acid metabolism and excretion, will provide novel insights into the pathogenesis of uric acid stones, and open the way for new therapeutic strategies.\n"

"The disintegrin-like and cysteine-rich domains of ADAM-9 mediate interactions between melanoma cells and fibroblasts. \nA characteristic of malignant cells is their capacity to invade their surrounding and to metastasize to distant organs. During these processes, proteolytic activities of tumor and stromal cells modify the extracellular matrix to produce a microenvironment suitable for their growth and migration. In recent years the family of ADAM proteases has been ascribed important roles in these processes. ADAM-9 is expressed in human melanoma at the tumor-stroma border where direct or indirect interactions between tumor cells and fibroblasts occur. To analyze the role of ADAM-9 for the interaction between melanoma cells and stromal fibroblasts, we produced the recombinant disintegrin-like and cysteine-rich domain of ADAM-9 (DC-9). Melanoma cells and human fibroblasts adhered to immobilized DC-9 in a Mn(2+)-dependent fashion suggesting an integrin-mediated process. Inhibition studies showed that adhesion of fibroblasts was mediated by several beta1 integrin receptors independent of the RGD and ECD recognition motif. Furthermore, interaction of fibroblasts and high invasive melanoma cells with soluble recombinant DC-9 resulted in enhanced expression of MMP-1 and MMP-2. Silencing of ADAM-9 in melanoma cells significantly reduced cell adhesion to fibroblasts. Ablation of ADAM-9 in fibroblasts almost completely abolished these cellular interactions and melanoma cell invasion in vitro. In summary, these results suggest that ADAM-9 expression plays an important role in mediating cell-cell contacts between fibroblasts and melanoma cells and that these interactions contribute to proteolytic activities required during invasion of melanoma cells.\n"

"Relationship of self-concept during late pregnancy to neonatal perception and parenting profile.\nThirty-one gravidas were studied to examine the relationship between a woman's feelings about herself during late pregnancy, her perception of her newborn, and her profile of parenting. The Tennessee Self-Concept Scale was completed during the third trimester of pregnancy, the Neonatal Perception Inventory I at one-to-two days postpartum, and the Neonatal Perception Inventory II and the Michigan Screening Profile of Parenting at four-to-six weeks postpartum. When considered separately, no positive significant relationships were found between scores on these variables. However, all subjects with negative scores on both self-concept and neonatal perception had negative scores on at least two subscales of the parenting profile.\n"

"Convergence of p53 and TGF-beta signaling networks. \np53 is a protein with many talents. One of the most fundamental is the ability to act as essential growth checkpoint that protects cells against cellular transformation. p53 does so through the induction of genes leading to growth arrest or apoptosis. Most of the studies focusing on the mechanisms of p53 activity have been performed in cultured cells upon treatment with well-established p53-activating inputs, such as high doses of radiations, DNA-damaging drugs and activated oncogenes. However, how the tumor suppressive functions of p53 become concerted with the extracellular cues arriving at the cell surface during tissue homeostasis, remains largely unknown. Intriguingly, two recent papers have shed new light into this unexplored field, indicating that p53 plays a key role in TGF-beta-induced growth arrest and, unexpectedly, in the developmental effects of TGF-beta in early embryos. Here we review and comment on these findings and on their implications for cancer biology.\n"

"Magnesium for treatment of asthma in children.\nQUESTION: Magnesium is considered adjuvant therapy for moderate to severe asthma exacerbations in adults, but can it be used to treat children? ANSWER: Magnesium seems to be beneficial in the treatment of moderate to severe asthma in children. It is a safe drug to administer, but there have been minor side effects reported, such as epigastric or facial warmth, flushing, pain and numbness at the infusion site, dry mouth, malaise, and hypotension. Owing to its bronchodilating and anti-inflammatory effects, magnesium is an encouraging adjuvant therapy for pediatric patients who do not respond to conventional treatment in acute severe exacerbations. Future studies should focus on establishing the optimal dosage for maximal benefits and the best route of administration. Magnesium should also be considered as a prophylactic treatment.\n"

"NIH3T3 transfectant containing human K-ras oncogene shows enhanced metastatic activity after in vivo tumor growth or co-culture with fibroblasts. \nA clone of NIH3T3 transformant (H-3), obtained by transfecting genomic DNA of a human colon carcinoma cell line, contains human K-ras oncogene and yields metastatic pulmonary nodules after intravenous injection of the cells into nude mice. This metastatic ability was enhanced remarkably after in vivo tumor growth (subcutaneous tumor formation in nude mice) accompanied by increased mRNA expression and gene amplification of the human-derived K-ras oncogene, while it declined gradually as the passage number increased in vitro, with corresponding decreases of gene amplification and mRNA expression. Six subclones were randomly selected from H-3 cells which had been subcultured to passage 22. All of the clones in culture showed almost the same low level of metastatic ability and exhibited little K-ras oncogene amplification with correspondingly low mRNA expression. However, after they formed tumors in nude mice, every clone acquired high metastatic ability and the gene amplification increased, with elevated mRNA expression. These experimental facts indicated that acquisition of metastatic ability coupled with the function of K-ras oncogene was conditional in nature, being strongly affected by in vivo tumor circumstances. The low metastatic and G-418-resistant H-3 cells were co-cultured with BALB/c3T3 fibroblasts for 2-4 weeks. After removal of fibroblasts by exposure to G-418, the tumor cells exhibited increased metastatic ability and human K-ras oncogene mRNA, suggesting an intimate interaction between H-3 cells and fibroblasts influencing the function of transfected human K-ras oncogene. Fibroblasts of the host animal may thus have an important role in generating enhanced metastatic activity of H-3 cells.\n"

"Screening method for insecticidal activity using first instars of black blow fly (Diptera: Calliphoridae).\nA bioassay method suitable for rapid mass screening of fermentation and synthetic organic compounds for insecticidal activity is described. The test, which uses first instars of susceptible black blow fly, Phormia regina (Meigen), in a bovine serum medium, detects insecticidal activity with reproducible results. It is capable of selecting the most active compound in structure-activity relationships by minimum effective dose concentration studies. The bioassay system is easy to operate and requires only a minute quantity of chemical compound.\n"

"Oncogenic mechanisms of Evi-1 protein. \nAlthough Evi-1 is thought to promote growth or block differentiation in some cell types, its biological functions have not been elucidated. To explore the mechanisms underlying Evi-1-induced oncogenesis, we investigated whether Evi-1 affects the signaling of transforming growth factor beta (TGF-beta), which inhibits proliferation of a wide range of cell types and is one of the most studied growth regulatory factors. We demonstrated that Evi-1 represses TGF-beta signaling and antagonizes its growth-inhibitory effects. Two separate regions of Evi-1 are responsible for this repression, one of which is the first zinc-finger domain. Through this domain, Evi-1 physically interacts with Smad3, an intracellular mediator of TGF-beta signaling, thereby suppressing the transcriptional activity of Smad3. These results define a novel function of Evi-1 as a repressor of signaling components of TGF-beta. We also demonstrated that Evi-1 represses Smad-induced transcriptional activation by recruiting CtBP as a corepressor. Evi-1 associates with CtBP1 through one of the CtBP-binding consensus motifs within the region from amino acid 544 to 607, and this association is required for the efficient inhibition of TGF-beta signaling. A specific histone deacetylase (HDAc) inhibitor, trichostatin A (TSA), alleviates Evi-1-mediated repression of TGF-beta signaling, suggesting that HDAc is involved in transcriptional repression by Evi-1. This identifies a novel function of Evi-1 as a member of corepressor complexes and suggests that aberrant recruitment of corepressors is one of the mechanisms involved in Evi-1-induced leukemogenesis. These results indicate that specific HDAc inhibitors may be useful in the treatment of Evi-1-induced neoplastic tumors, including myeloid leukemias.\n"

"Acylase I-catalyzed deacetylation of N-acetyl-L-cysteine and S-alkyl-N-acetyl-L-cysteines.\nThe aminoacylase that catalyzes the hydrolysis of N-acetyl-L-cysteine (NAC) was identified as acylase I after purification by column chromatography and electrophoretic analysis. Rat kidney cytosol was fractionated by ammonium sulfate precipitation, and the proteins were separated by ion-exchange column chromatography, gel-filtration column chromatography, and hydrophobic interaction column chromatography. Acylase activity with NAC and N-acetyl-L-methionine (NAM), a known substrate for acylase I, as substrates coeluted during all chromatographic steps. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed that the protein was purified to near homogeneity and had a subunit Mr of 43 000, which is identical with the Mr of acylase I from porcine kidney and bovine liver. n-Butylmalonic acid was a slow-binding inhibitor of acylase I and inhibited the deacetylation of NAC with a Ki of 192 +/- 27 microM. These results show that acylase I catalyzes the deacetylation of NAC. The acylase I-catalyzed deacetylation of a range of S-alkyl-N-acetyl-L-cysteines, their carbon and oxygen analogues, and the selenium analogue of NAM was also studied with porcine kidney acylase I. The specific activity of the acylase I-catalyzed deacetylation of these substrates was related to their calculated molar volumes and log P values. The S-alkyl-N-acetyl-L-cysteines with short (C0-C3) and unbranched S-alkyl substituents were good acylase I substrates, whereas the S-alkyl-N-acetyl-L-cysteines with long (>C3) and branched S-alkyl substituents were poLr acylase I substrates. The carbon and oxygen analogues of S-methyl-N-acetyl-L-cysteine and the carbon analogue of S-ethyl-N-acetyl-L-cysteine were poor acylase I substrates, whereas the selenium analogue of NAM was a good acylase I substrate.\n"

"Fluoro-Jade B staining following zymosan microinjection into the spinal cord white matter.\n1. The fluorescein derivate Fluoro-Jade B (FJB), which primarily labels dead or dying neurons, was used to study the acute focal inflammation in the spinal cord white matter. Inflammation was induced by microinjection of the yeast particulate zymosan to evaluate the biological effects of intraspinal macrophages activation without the confounding effects of physical trauma. 2. A single bolus of zymosan (Sigma, 75 nL) was stereotaxically injected at the thoracic level into the lateral white matter of rat spinal cord. A standard Fluoro-Jade B staining protocol was applied to spinal cord sections at 6, 12, 24 h and 2, 4 days postinjection. Neutral Red, NADPH-diaphorase, Iba1-IR, and DAPI staining protocols accomplished examination of the cells participating in the acute inflammatory response. 3. Zymosan caused formation of clearly delineated inflammation lesions localized in the lateral white matter of the spinal cord. Fluoro-Jade B stained cells in the area of inflammation were not observed at 12 h postinjection while mild FJB staining appeared at 24 h and intense staining was observed at 2 and 4 days postinjection. 4. This study shows that the acute response to zymosan-induced inflammation in the rat spinal cord white matter causes a gradual appearance of phagocytic microglia/macrophages and delayed FJB staining of the inflammatory cells. 5. FJB, a reliable marker of dying neurons, is a more universal agent than formerly believed. One possible explanation for the gradual appearance of FJB-stained cells in the area of inflammation is that specific time is required for sufficient levels of proteins and/or myelin debris of axonal origin to appear in the cytoplasm of phagocytic microglia/macrophages.\n"

"[Reconstruction of hepatic artery in adult to adult living donor liver transplantation in 104 patients].\nOBJECTIVE:\nTo report the experience of hepatic artery reconstruction with adult-to-adult living donor liver transplantation (ALDLT) using right lobe liver grafts.\nMETHODS:\nFrom January 2002 to August 2007, 104 patients underwent ALDLT using right lobe grafts. Hepatic arteries of donors and recipients were assessed carefully with spiral CT angiography and DSA before ALDLT. All patients underwent reconstruction of hepatic artery between right lobe liver grafts of donor and recipient which included the anastomosis between right hepatic artery of donors and recipients; the reconstruction of right hepatic artery between donor grafts and left hepatic artery of recipients; interpositional bypass using autogenous saphenous vein and cryopreserved iliac artery between right hepatic artery of donors and hepatic artery, common hepatic artery and abdominal aorta of recipients. The microsurgical technique was employed under the magnification of 3.5 times and operative microscope of 5-10 times.\nRESULTS:\nIn these series, HAT occurred in 2 recipients at Days 1 and 7 post-ALDLT (1.9%). Both were revascularized with autogenous saphenous vein between right hepatic artery of donor and abdominal aorta of recipient. HAT occurred in 1 recipient at Days 90 post-ALDLT, but no symptom was presented. There was no severe complication and mortality related to hepatic artery reconstruction in recipients. No HAT, hepatic artery stenosis and aneurysm occurred during the follow-up period of 2-60 months. The 1, 2 and 3-year survival rates were 89.3%, 76.0% and 69.3% respectively.\nCONCLUSION:\nCareful evaluation of hepatic artery condition and using microsurgical techniques are important for safer arterial reconstruction and a long-term patency of hepatic artery in living donor liver transplantation in adults using right lobe liver grafts.\n"

"Urokinase receptor: a molecular organizer in cellular communication.\nIn a variety of cell types, the glycolipid-anchored urokinase receptor (uPAR) is colocalized pericellularly with components of the plasminogen activation system and endocytosis receptors. uPAR is also coexpressed with caveolin and members of the integrin adhesion receptor superfamily. The formation of functional units with these various proteins allows the uPAR to mediate the focused proteolysis required for cell migration and invasion and to contribute both directly and indirectly to cell adhesive processes in a non-proteolytic fashion. This dual activity, together with the initiation of signal transduction pathways by uPAR, is believed to influence cellular behaviour in angiogenesis, inflammation, wound repair and tumor progression/metastasis and open up the way for uPAR-based therapeutic approaches.\n"

"Early post-mortem metabolism and muscle shortening in the Pectoralis major muscle of broiler chickens.\nThree experiments were conducted to examine the effects of sodium pentobarbital (SP), iodoacetate (IO), tubocurarine (TC), and surgical denervation (DN) on early rigor development in broiler breast muscle. In Experiment 1, birds were either anesthetized or not with SP before receiving an injection of IO or TC or maintained as noninjected controls. Experiment 2 was identical except that a treatment of denervation of the breast muscle was added. Experiment 3 was conducted to contrast birds at 1 day (DN1) and 3 days (DN3) denervation prior to slaughter to nonoperated controls. Measurements of muscle lactate, ATP, R value (ratio of inosine to adenine nucleotides), pH, sarcomere lengths, and shear were used to evaluate treatment effects. Results for Experiment 1 showed no significant differences among treatment and control groups for ATP and lactate contents, R values, or sarcomere lengths; however, significantly lower pH and higher shear values were observed for control birds. In Experiment 2, no significant differences were observed among the treatment groups for ATP, R values, or sarcomere lengths. However, lactate and shear values were significantly lower, and pH higher, for the DN and SP treated birds. Experiment 3 resulted in lower lactate and higher pH values for the DN3 treatment in comparison with both DN1 and control groups. Results of these studies indicate that the use of SP and DN can be used to alter the early profiles of rigor development.\n"

"The differential regulation of human telomerase reverse transcriptase and vascular endothelial growth factor may contribute to the clinically more aggressive behavior of p63-positive breast carcinomas.\np63, a p53 homologue, is a myoepithelial cell marker in the normal mammary gland but p63-positive neoplastic cells may be found in up to 11% of invasive breast carcinomas. This study aims to verify the relationship between p63 expression and several clinicopathological features and tumor markers of clinical significance in breast pathology including key regulators of the cell cycle, oncogenes, apoptosis-related proteins, metalloproteinases and their inhibitors. Immunohistochemistry with 27 primary antibodies was performed in 100 formalin-fixed paraffin-embedded samples of invasive ductal carcinomas. p63-positive cells were found in 16% of carcinomas. p63-positive carcinomas were poorly differentiated, hormone receptor-negative neoplasms with a high proliferation rate. p63 also correlated with advanced pathological stage, tumor size, and the expression of human telomerase reverse transcriptase (hTERT), tissue inhibitor of matrix metalloproteinase 1 (TIMP1) and vascular endothelial growth factor (VEGF). The expression of TIMP1 suggests that the anti-proteolytic stimuli may be preponderant in p63-positive carcinomas. hTERT activity is associated with nodal metastases and cellular proliferation. VEGF regulates angiogenesis, which is also a fundamental event in the process of tumor growth and metastatic dissemination. Thus, the differential regulation of hTERT and VEGF in p63-positive breast carcinomas may contribute to the clinically more aggressive behavior of these neoplasms.\n"

"Aflibercept (AVE0005): an alternative strategy for inhibiting tumour angiogenesis by vascular endothelial growth factors.\nBACKGROUND: Aberrant angiogenesis is a landmark feature in cancer, which is important for proliferation, growth and metastasis, and is mediated by various pro-angiogenic factors. The VEGF pathway is one of the most important and best-studied angiogenic pathways. Inhibition of this pathway may provide clinical benefits to cancer patients. OBJECTIVES: Strategies to inhibit the VEGF pathway, including antibodies to VEGF, antibodies to the extracellular domain of VEGFR-1 or VEGFR-2, decoy receptors for VEGF and tyrosine kinase inhibitors of VEGFRs, are summarized. METHODS: This review outlines and compares the latest development of these strategies, with emphasis on aflibercept, a novel decoy fusion protein of domain 2 of VEGFR-1 and domain 3 of VEGFR-2 with the Fc fragment of IgG1. RESULTS: Aflibercept was shown to have early clinical activity. Multiple studies are ongoing to determine the clinical benefits of aflibercept in cancer patients.\n"

"Glucose and lactate metabolism in C6 glioma cells: evidence for the preferential utilization of lactate for cell oxidative metabolism.\n13C and 1H nuclear magnetic resonance spectroscopy (NMR) was used to investigate the metabolism of L-lactate and D-glucose in C6 glioma cells. The 13C enrichment of cell metabolites was examined after a 4-h incubation in media containing 5.5 mM glucose and 11 mM lactate, each metabolite being alternatively labelled with either [1-13C]D-glucose or [3-13C]L-lactate. The results indicated that exogenous lactate was the major substrate for oxidative metabolism. They were consistent with the concept of the existence of 2 pools of both lactate and pyruvate, of which 1 pool was closely connected with exogenous lactate and oxidative metabolism, and the other pool was closely related to glycolysis and disconnected from oxidative metabolism. The molecular basis of this behaviour could be related to different locations for the lactate dehydrogenase isoenzymes, as suggested by their immunohistochemical labelling.\n"

"Ovarian cancers overexpress the antimicrobial protein hCAP-18 and its derivative LL-37 increases ovarian cancer cell proliferation and invasion.\nThe role of the pro-inflammatory peptide, LL-37, and its pro-form, human cationic antimicrobial protein 18 (hCAP-18), in cancer development and progression is poorly understood. In damaged and inflamed tissue, LL-37 functions as a chemoattractant, mitogen and pro-angiogenic factor suggesting that the peptide may potentiate tumor progression. The aim of this study was to characterize the distribution of hCAP-18/LL-37 in normal and cancerous ovarian tissue and to examine the effects of LL-37 on ovarian cancer cells. Expression of hCAP-18/LL-37 was localized to immune and granulosa cells of normal ovarian tissue. By contrast, ovarian tumors displayed significantly higher levels of hCAP-18/LL-37 where expression was observed in tumor and stromal cells. Protein expression was statistically compared to the degree of immune cell infiltration and microvessel density in epithelial-derived ovarian tumors and a significant correlation was observed for both. It was demonstrated that ovarian tumor tissue lysates and ovarian cancer cell lines express hCAP-18/LL-37. Treatment of ovarian cancer cell lines with recombinant LL-37 stimulated proliferation, chemotaxis, invasion and matrix metalloproteinase expression. These data demonstrate for the first time that hCAP-18/LL-37 is significantly overexpressed in ovarian tumors and suggest LL-37 may contribute to ovarian tumorigenesis through direct stimulation of tumor cells, initiation of angiogenesis and recruitment of immune cells. These data provide further evidence of the existing relationship between pro-inflammatory molecules and ovarian cancer progression.\n"

"Subcellular localisation of BAG-1 and its regulation of vitamin D receptor-mediated transactivation and involucrin expression in oral keratinocytes: implications for oral carcinogenesis. \nIn oral cancers, cytoplasmic BAG-1 overexpression is a marker of poor prognosis. BAG-1 regulates cellular growth, differentiation and survival through interactions with diverse proteins, including the vitamin D receptor (VDR), a key regulator of keratinocyte growth and differentiation. BAG-1 is expressed ubiquitously in human cells as three major isoforms of 50 kDa (BAG-1L), 46 kDa (BAG-1M) and 36 kDa (BAG-1S) from a single mRNA. In oral keratinocytes BAG-1L, but not BAG-1M and BAG-1S, enhanced VDR transactivation in response to 1alpha,25-dihydroxyvitamin D3. BAG-1L was nucleoplasmic and nucleolar, whereas BAG-1S and BAG-1M were cytoplasmic and nucleoplasmic in localisation. Having identified the nucleolar localisation sequence in BAG-1L, we showed that mutation of this sequence did not prevent BAG-1L from potentiating VDR activity. BAG-1L also potentiated transactivation of known vitamin-D-responsive gene promoters, osteocalcin and 24-hydroxylase, and enhanced VDR-dependent transcription and protein expression of the keratinocyte differentiation marker, involucrin. These results demonstrate endogenous gene regulation by BAG-1L by potentiating nuclear hormone receptor function and suggest a role for BAG-1L in 24-hydroxylase regulation of vitamin D metabolism and the cellular response of oral keratinocytes to 1alpha,25-dihydroxyvitamin D3. By contrast to the cytoplasmic BAG-1 isoforms, BAG-1L may act to suppress tumorigenesis.\n"

"Tumors of the retinal pigment epithelium metastasize to inguinal lymph nodes and spleen in tyrosinase-related protein 1/SV40 T antigen transgenic mice. \nThe pigment epithelium of the retina (RPE) is derived from the optic cup and is essential for function and development of the eye. We produced a transgenic mouse line that expresses simian virus (SV40) transforming sequences under control of the 1.4 kb tyrosinase-related protein 1 (TRP-1) promoter, targeting expression of T antigen (Tag) to the RPE. In transgenic embryos, RPE cells proliferated in the anterior part of the eye and near the optic nerve. This resulted in formation of tumors, which were pigmented and of epithelial origin. In 3 months-old mice, pigmented cells were detected in spleen and inguinal lymph nodes. In spleen, tyrosinase, TRP-1 and SV40 Tag were expressed and tyrosinase was enzymatically active. Pigmented regions were positive for an epithelial marker, cytokeratin. Cell lines were established from tumor and metastases and kept in culture for more than 2 months. These were pigmented, and maintained expression of tyrosinase, TRP-1, cytokeratin and SV40 Tag. This demonstrates that RPE tumor cells metastasize to lymph node and spleen. In conclusion, the metastasis from TRP-1/Tag RPE tumors towards spleen and lymph nodes serves as potential tool to investigate biology and metastasis of tumors derived from the pigment epithelium.\n"

"The relationship between brain activity and peak grip force is modulated by corticospinal system integrity after subcortical stroke.\nIn healthy human subjects, the relative contribution of cortical regions to motor performance varies with the task parameters. Additionally, after stroke, recruitment of cortical areas during a simple motor task varies with corticospinal system integrity. We investigated whether the pattern of motor system recruitment in a task involving increasingly forceful hand grips is influenced by the degree of corticospinal system damage. Nine chronic subcortical stroke patients and nine age-matched controls underwent functional magnetic brain imaging whilst performing repetitive isometric hand grips. Target grip forces were varied between 15% and 45% of individual maximum grip force. Corticospinal system functional integrity was assessed with transcranial magnetic stimulation. Averaged across all forces, there was more task-related activation compared with rest in the secondary motor areas of patients with greater corticospinal system damage, confirming previous reports. However, here we were primarily interested in regional brain activation, which covaried with the amount of force generated, implying a prominent executive role in force production. We found that in control subjects and patients with lesser corticospinal system damage, signal change increased linearly with increasing force output in contralateral primary motor cortex, supplementary motor area and ipsilateral cerebellum. In contrast, in patients with greater corticospinal system damage, force-related signal changes were seen mainly in contralesional dorsolateral premotor cortex, bilateral ventrolateral premotor cortices and contralesional cerebellum, but not ipsilesional primary motor cortex. These findings suggest that the premotor cortices might play a new and functionally relevant role in controlling force production in patients with more severe corticospinal system disruption.\n"

"Growth state-dependent regulation of protein kinase C in normal and transformed murine cells. \nWe determined whether growth state can influence the action of protein kinase C by measuring protein kinase C activity in growing and stationary cultures of normal and transformed cells. Two approaches were used to measure protein kinase C: assay of intact cells for inhibition of epidermal growth factor (EGF) binding in response to phorbol dibutyrate (PDBu); and assay of detergent extracts for total calcium, phospholipid-dependent kinase activity. In extracts of growing and stationary Swiss 3T3 cells, the total amount of protein kinase C activity was similar, indicating that growth state does not alter the level of enzyme in the cell. The short-term response of Swiss 3T3 cells to an activator of protein kinase C also appeared to be independent of growth state, since the 50% effective dose for PDBu inhibition of EGF binding to its receptor was approximately 7 nM for both growth conditions. In contrast, the response of cells to long-term treatment with PDBu was significantly different depending upon the initial growth state of the cells. In both growth states, PDBu caused loss of protein kinase C activity, which reflected a loss in protein mass as determined by immunoblotting with antiserum to protein kinase C. However, the maximum decrease approached 100% in stationary cultures versus approximately 75% in growing cells. Protein kinase C levels in several transformed cell lines were subject to down modulation in a similar growth state-dependent manner. Further, the inhibition of EGF binding by tumor promoters following long-term treatment of Swiss 3T3 cells with PDBu also varied with growth state. In down modulated growing cells, PDBu caused almost complete inhibition of EGF binding, whereas in down modulated stationary cells, minimal inhibition of EGF binding by PDBu was observed. These results suggest that prolonged treatment with tumor promoters alters the sensitivity of cells to activators of protein kinase C in a growth state-dependent manner.\n"

"The value of serum S-100beta and interleukins as tumour markers in advanced melanoma. \nRecently serum S-100beta has shown promise as a tumour marker in melanoma; however, its use as a prognostic marker in the advanced stage needs to be confirmed. Interleukins (ILs) may mediate regression or progression of cancer. In order to study their relation to the metastatic profile and survival, we evaluated the association between pretreatment serum levels of S-100beta, IL-6, IL-10 and IL-12 and metastatic site and survival in 50 patients with advanced melanoma who were to receive chemoimmunotherapy. Patients with liver and/or bone metastases had significantly higher median concentrations of S-100beta, IL-6 and IL-10 than those with only skin, nodal and/or lung involvement. The differences in IL-12 levels were unremarkable. Using univariate analysis, the S-100beta level and metastatic profile were found to be statistically significant prognostic factors for survival. Using multivariate analysis the S-100beta level was the most powerful prognostic indicator, while the metastatic profile was found to be significant after exclusion of S-100beta. The findings suggest that elevated serum levels of S-100beta, IL-6 and IL-10 reflect concurrent liver or bone metastases in melanoma. S-100beta is also an independent prognostic marker. Pretreatment IL levels were not associated with outcome.\n"
