Which hormone abnormalities are common in Williams syndrome ?
[ "Thyroid hormone abnormalities are common in Williams syndrome. Oxytocin and vasopressin, cortisol, growth hormone and calcitonin were also implicated in the Williams syndrome." ]
[ "thyroid" ]
[ "WS and TD participants had similar profiles in a familiar setting, while participants with WS had elevated cortisol late in the day in the novel setting when social demands were higher. The cortisol awakening response in WS was associated with parent-reported levels of somatic complaints and social difficulties. Results suggest that adults with WS have a typical diurnal cortisol profile that may be sensitive to social and activity transitions throughout the day.", "Results revealed significantly higher median levels of OT in WS versus controls at baseline, with a less marked increase in AVP. Further, in WS, OT and AVP increased in response to music and to cold, with greater variability and an amplified peak release compared to controls. In WS, baseline OT but not AVP, was correlated positively with approach, but negatively with adaptive social behaviors. These results indicate that WS deleted genes perturb hypothalamic-pituitary release not only of OT but also of AVP, implicating more complex neuropeptide circuitry for WS features and providing evidence for their roles in endogenous regulation of human social behavior. ", "Three quarters of the WS subjects showed abnormal glucose curves, meeting diagnostic criteria for either diabetes or the pre-diabetic state of impaired glucose tolerance. Fasting mean glucose and median insulin levels did not differ significantly in the total WS cohort versus age-gender-BMI matched controls, though the glucose area under the curve was greater in the WS subjects. ", "Williams syndrome (WS) is characterized by cardiovascular disease (elastin arteriopathy, peripheral pulmonary stenosis, supravalvular aortic stenosis, hypertension), distinctive facies, connective tissue abnormalities, intellectual disability (usually mild), a specific cognitive profile, unique personality characteristics, growth abnormalities, and endocrine abnormalities (hypercalcemia, hypercalciuria, hypothyroidism, and early puberty).", "In the Williams-Beuren syndrome (WBS), disorders of the thyroid function and morphology have been reported and programs of thyroid screening and surveillance are recommended. ", "In this report we describe an infant with WBS and congenital hypothyroidism, due to an important thyroid hypoplasia. The patient, a 1-month-old female, negative at primary neonatal thyroid screening, was referred to our hospital for dyspnea. Thyroid function tests showed a raised TSH (42 mIU/l; normal range 0.5-4 mIU/l) with a low FT(4) concentration (10.21 pmol/l; normal range: 10.29-24.45 pmol/l). Ultrasound examination of the neck showed a significant thyroid hypoplasia, whereas (99m)Tc-pertechnetate thyroid scintigraphy evidenced a thyroid gland in normal position, with reduced shape and overall weak fixation. ", "Thyroid hypoplasia is a frequent characteristic of WBS and abnormalities of thyroid function are common in patients with this feature. Therefore, the possibility of congenital hypothyroidism should always be taken into consideration too and, even if congenital hypothyroidism neonatal screening is negative, thyroid (morphology and function) evaluation should be regularly assessed when the diagnosis is made and, thereafter, every year in the first years of life.", "As growth hormone (GH) deficiency was diagnosed by an additional GH-stimulation test, we commenced with a GH-treatment. ", "None of our patients had overt hypothyroidism; 29 patients (31.5%) had subclinical hypothyroidism. ", "Thyroid involvement in Williams syndrome (WS) was recently reported in two small groups of patients, both showing an increased prevalence of elevation of TSH serum concentration; in one of the two reports, 70% of the patients demonstrated a hypoplasia of thyroid gland as well. ", "Our study confirms the increased incidence of both elevated TSH serum values (37.9% in our sample) and thyroid gland hypoplasia (74.7%).", "A WS patient with CPP is presented, whose pubertal development and bone age progression were arrested by administration of GnRH analogues. ", " This study confirms the presence of alterations of thyroid function in WS and also suggests the frequent occurrence of abnormalities of thyroid morphology in these patients.", "We report a female infant with confirmed WBS who, through provocative testing, was found to have GHD and who responded satisfactorily to hGH therapy. ", "In conclusion, GH deficiency might contribute to the growth failure in a number of patients with WBS and in such cases hGH therapy will most likely improve final height.", "Thyrotropin level was very high (>50 microU/ml; normal value 0.2-4 microU/ml), while serum free T(3) (FT3) and free T(4) (FT4) levels were normal (FT3 3.6 pg/ml, normal value 2.8-5.6 pg/ml; FT4 11.6 pg/ml, normal value 6.6-14 pg/ml); antithyroid autoantibodies were absent. ", "Recently a case of thyroid hemiagenesis in a child with WS has been reported; our patient underscores the association of hypothyroidism and WS. ", "Thyroid hemiagenesis and elevated thyrotropin levels in a child with Williams syndrome.", "A girl with Williams syndrome (WS) presented with elevated thyrotropin (TSH) levels (7.0 microU/ml), normal free thyroid hormone concentrations, and absent antithyroid autoantibodies.", "TSH response to thyrotropin-releasing hormone (TRH) injection (200 microg/mq, i.v.) was exaggerated and prolonged, suggesting subclinical hypothyroidism. The biological activity of circulating TSH was slightly below the normal range [TSH bioactivity (B) to immunoreactivity (I) ratio (TSH B/I) = 0.4, normal: 0.6-2.2]. These abnormalities are similar to those seen in patients with hypothalamic hypothyroidism.", "However, abnormalities of the hypothalamic-pituitary-thyroid (HPT) axis and thyroid dysgenesis have been found in other WS cases. ", "We report a boy with confirmed Williams-Beuren syndrome, who was found to have classical growth hormone deficiency and responded well to growth hormone therapy. ", "Although growth hormone deficiency is not likely to be a common cause of short stature in Williams-Beuren syndrome, we nevertheless recommend evaluation of the growth hormone-insulin-like growth factor I axis in all cases.", "Endocrinological examinations revealed hypergonadotropic hypogonadism. Prolonged and exaggerated responses of adrenocorticotropin (ACTH) to insulin-induced hypoglycemia and corticotropin releasing hormone (CRH) were also noted. ", "Involvement of the calcitonin/CGRP gene in Williams syndrome is postulated on the basis that Williams syndrome children often have infantile hypercalcemia and deficient expression of calcitonin, a hormone that lowers serum calcium levels. ", "These findings suggest that the calcitonin deficiency might be due either to mutations elsewhere in the gene or to defects in the cellular machinery needed for calcitonin synthesis and/or secretion.", "It has been suggested that a defect in calcitonin function may play a role in Williams syndrome. ", " These patients were found to have significantly higher mean baseline calcium concentrations, delayed clearance of calcium after intravenous calcium loading, and blunted calcitonin responses after calcium infusion, compared with a group of seven normal children.", "Our studies demonstrate that patients with Williams syndrome have a defect in the synthesis or release of immunoreactive calcitonin. A deficiency of calcitonin may explain the abnormalities of calcium metabolism seen in these patients and can serve as an important endocrine marker for Williams syndrome.", "Additional periodic evaluations during childhood: serum concentration of calcium, thyroid function, hearing, and renal and bladder ultrasound examination. Periodic evaluations during adulthood: glucose tolerance; cardiac evaluation for mitral valve prolapse, aortic insufficiency, and arterial stenosis; and ophthalmologic evaluation for cataracts.", "Subclinical hypothyroidism is a frequent but stable finding in young children with WS. The great majority of patients with WS >10 years, either with normal or hypoplastic thyroid, have normal thyroid function.", " Three cases (15%) of subclinical hypothyroidism were identified. Overt hypothyroidism was diagnosed in two cases (10%)." ]

Albumin depletion is a common first step for proteomic analysis of CSF fluid. What is the advantage and disadvantage of this procedure?
[ "Depletion of the high abundant protein Albumin from CSF samples is improving the detection of lower abundant proteins but may also lead to the potential loss of non-target proteins." ]

How are lincRNA affecting the regulation of gene expression?
[ "lincRNA may function either as modulators of epigenetic mark deposition or as endogenous antagonists for microRNA binding. A lincRNA, linc-RoR, may function as a key competing endogenous RNA to link the network of miRNAs and core TFs, e.g., Oct4, Sox2, and Nanog. Mdig is involved in the regulation of H3K9me3 to influence the heterochromatin structure of the genome and the expression of genes important for cell growth or transformation. Observed biases in lincRNA genomic locations and expression profiles are consistent with some of these lincRNAs being involved in the regulation of neighboring protein-coding genes with developmental functions." ]

What is known about thalidomide therapy and survival of glioblastoma patients?
[ "Findings regarding clinical value of thalidomide in terms of survival in patients with glioblastoma remain mixed. It has been shown that thalidomide can improve survival of recurrent glioblastoma patients. However, other authors have not confirmed these findings. Furthermore, thalidomide did not improve survival of newly diagnosed glioblastoma and pediatric glioblastoma patients." ]
[]
[ "In conclusion, thalidomide given simultaneously with radiation therapy was safe, but did not improve survival in patients with newly diagnosed glioblastoma.", "The authors previously reported improved outcome in patients with recurrent glioblastoma treated with thalidomide and irinotecan compared with historical controls. ", "CONCLUSIONS: The combination of thalidomide and irinotecan did not achieve sufficient efficacy to warrant further investigation against AG, although a subset of patients experienced prolonged PFS/OS. ", "The treatment regimen was well tolerated. OS (median, 74 weeks) and PFS (median, 36 weeks) results from the current trial were comparable to those from a prior phase II study using erlotinib and were significantly better than those from 2 other previous studies that used thalidomide or cis-retinoic acid, all in combination with temozolomide plus RT.", "The addition of celecoxib and thalidomide to adjuvant temozolomide was well tolerated but did not meet the primary end point of improvement of 4-month PFS from study enrollment.", "CONCLUSION: The combination of irinotecan and thalidomide has limited activity against GBM.", "The combination of irinotecan, a cytotoxic agent, and thalidomide, an antiangiogenic agent, shows promising activity against recurrent GBM in patients not receiving EIACs and warrants further study. ", "CONCLUSION: The administration of temozolomide in association with thalidomide after radiotherapy (RT) does not offer an advantage over temozolomide alone in adults with newly diagnosed GBM. The two therapeutic strategies produce similar results for survival, but the latter regimen shows a moderate increase in toxicity.", "CONCLUSION: This drug combination was reasonably safe, but with little indication of improvement compared to temozolomide alone.", "In this small patient sample adding thalidomide to radiation did not improve TTP or TTD from historical controls, however, toxicity appeared to be increased.", "Experimental studies have demonstrated that thalidomide has anti-tumor activity mediated by blockage of angiogenesis, with clinical efficacy in multiple myeloma, glioblastoma multiforme, and renal cell cancer. ", "CONCLUSIONS: The combined therapy was relatively well tolerated, but there was no survival advantage compared with historical studies using XRT either with adjuvant nitrosourea chemotherapy, with TMZ alone, or with the combination of TMZ and thalidomide.", "PURPOSE: The chemotherapeutic agent temozolomide (TMZ) and the antiangiogenic agent thalidomide have both demonstrated antitumor activity in patients with recurrent malignant glioma.", "CONCLUSIONS: This strategy of combination TMZ, thalid and RT was relatively well tolerated with favorable survival outcome for patients with GM when compared to patients not treated with adjuvant chemotherapy and similar to those who have received nitrosourea adjuvant chemotherapy. It is unclear the added advantage thalid has in combination with TMZ for this patient population.", "CONCLUSIONS: The combination of thalidomide and temozolomide in the treatment of GBM appears to be more effective than that of thalidomide alone with respect to survival, TTP, and neuroradiological documentation of progression, stable disease or response.

", "Eight patients were alive more than 1 year after starting thalidomide, although almost all with tumor progression. ", " In conclusion, thalidomide given simultaneously with radiation therapy was safe, but did not improve survival in patients with newly diagnosed glioblastoma.", "Thalidomide prolongs disease stabilization after conventional therapy in patients with recurrent glioblastoma.", "In conclusion, thalidomide given simultaneously with radiation therapy was safe, but did not improve survival in patients with newly diagnosed glioblastoma.", "No patients completed the planned 12 months of thalidomide therapy and all have since died of disease progression" ]

Are there transposon-free regions in mammalian genomes?
[ "Yes. Despite the presence of over 3 million transposons separated on average by approximately 500 bp, the human and mouse genomes each contain almost 1000 transposon-free regions (TFRs) over 10 kb in length. The majority of human TFRs correlate with orthologous TFRs in the mouse, despite the fact that most transposons are lineage specific. Many human TFRs also overlap with orthologous TFRs in the marsupial opossum, indicating that these regions have remained refractory to transposon insertion for long evolutionary periods. Over 90% of the bases covered by TFRs are noncoding, much of which is not highly conserved. Most TFRs are not associated with unusual nucleotide composition, but are significantly associated with genes encoding developmental regulators, suggesting that they represent extended regions of regulatory information that are largely unable to tolerate insertions, a conclusion difficult to reconcile with current conceptions of gene regulation." ]

How effective is the dentritic cells treatment on cancer?
[ "Another approach to cancer therapy takes advantage of the normal role of the dendritic cell as an immune educator. Dendritic cells grab antigens from viruses, bacteria, or other organisms and wave them at T cells to recruit their help in an initial T cell immune response. This works well against foreign cells that enter the body, but cancer cells often evade the self/non-self detection system. By modifying dendritic cells, researchers are able to trigger a special kind of autoimmune response that includes a T cell attack of the cancer cells. Because a cancer antigen alone is not enough to rally the immune troops, scientists first fuse a cytokine to a tumor antigen with the hope that this will send a strong antigenic signal. Next, they grow a patient's dendritic cells in the incubator and let them take up this fused cytokine-tumor antigen. This enables the dendritic cells to mature and eventually display the same tumor antigens as appear on the patient's cancer cells. When these special mature dendritic cells are given back to the patient, they wave their newly acquired tumor antigens at the patient's immune system, and those T cells that can respond mount an attack on the patient's cancer cells." ]

[ "BAFF system plays a key role in the development of autoimmunity, especially in systemic lupus erythematosus (SLE). This often leads to the assumption that BAFF is mostly a B cell factor with a specific role in autoimmunity. Focus on BAFF and autoimmunity, driven by pharmaceutical successes with the recent approval of a novel targeted therapy Belimumab, has relegated other potential roles of BAFF to the background. Far from being SLE-specific, the BAFF system has a much broader relevance in infection, cancer and allergy. ", " silencing of suppressor of cytokine signalling 1 (Socs1) or stably expressing transgenic protein Ags in antigen-presenting dentritic cells (DCs) strongly enhances antigen-specific anti-tumour immunity. However, whether the strong and long-lasting T cell responses induced by the modified DCs could modulate the immunosuppressive tumour microenvironment has not been clarified. In this study, we explored the anti-tumour immunity of DCs modified by Socs1-shRNA lentiviral transduction combined with sustained expression of TRP2 in different tumour models. We showed that transfer Socs1-silenced or tumour antigen TRP2 persistent expressed DCs, or DCs modified by combination of Socs1-silencing and sustaining TRP2 expression prior to inoculation of tumour cells delayed B16 tumour cell growth, prolonged mouse survival and increased the ratio of CD8+ T/Treg as well as the CTL activity in tumours.

Notoriously in patients with severe anal intraepithelial neoplasia, the density of CD1a+ epithelial dendritic cells was influenced by the viral load of HIV-1.

However, membrane-bound CD40L can be cleaved into a soluble form, sCD40L, which contributes to systemic inflammatory and cardiovascular diseases, and induces survival signals in the absence of protein synthesis block, suggesting a deleterious side effect of CD40L gene therapy. We generated a plasmid encoding non-cleavable human CD40L mutant (pcDNA3.1+-CD40L-M) to determine the direct anti-proliferative and pro-apoptotic effects in CD40-positive lung adenocarcinoma cell line A549, to verify activation of immature dentritic cells (DCs) by co-cultivation with the transfected A549 cells and to evaluate the lower expression of sCD40L relative to that of wild-type CD40L (CD40L-WT) transfectant in cell-free supernatants.

The lymph node histological picture is also distinctive, constituted by a polymorphic infiltrate, a marked proliferation of high endothelial venules, and a dense meshwork of dentritic cells. The neoplastic CD4+ T-cells represent a minority of the lymph node cell population; its detection is facilitated by the aberrant expression of CD10. Almost all cases arbor an EBV infected B-cell population. Patients with AITL have a poor prognosis with conventional treatment, with a median overall survival of less than 3 years. Patients achieving a good clinical response seem beneficiate from a consolidation with high-dose therapy and autologous stem cell transplantation.

Additional approaches using ribozymes against Survivin mRNA, or dominant-negative cDNA to block Survivin function are in pre-clinical stages. Like many genes, Survivin is alternately spliced and a number of new splice variants have recently been identified. Expression of some of these splice variants correlates with loss of steroid receptors as well as the tumor suppressor p53, in some cancers, suggesting that like wild-type Survivin, at least some of these splice variants may also have prognostic relevance. This review will focus on the current understanding of the function of Survivin splice variants and their expression and sub-cellular localization in normal and neoplastic tissues as well as critically evaluating the potential toxicity of the Survivin directed therapies and their predicted effect on the alternatively spliced Survivin isoforms", " Immunotherapy applying ex vivo-generated and tumor antigen-loaded dentritic cells has been successfully introduced in clinical vaccination protocols and has proven to be feasible and effective in some patients. A better understanding of how dentritic cells succeed to induce and modulate immunity is necessary to optimally exploit dentritic cells in anticancer vaccines. The authors will review novel insights in antigen loading, activation and migration of dentritic cells and their impact on the application of ex vivo-generated dentritic cell vaccines. In addition, novel means to exploit dentritic cells in cancer vaccines by loading and activation of dentritic cells directly in situ and possible obstacles that should be overcome to induce long-lasting immunity in therapeutic settings will be discussed" ]

Is there a role for the cylindromatosis tumor suppressor (CYLD) in lung cancer?
[ "To explore a correlation between CYLD expression and responsiveness to TRAIL in lung cancer cell lines, we established lung cancer cell lines that stably express CYLD. Our data provided the first evidence that increased expression of CYLD directly blocks TRAIL-induced NF - B activation, and consequently increases TRAIL-induced apoptosis in lung cancer cells. CYLD may act as a therapeutic target of lung cancer. Targeting CYLD, in combination with TRAIL, may be a new strategy to treat lung cancer with high NF - B activity. Cyld encodes a 956-amino acid deubiquitinating enzyme, which is a negative regulator of nuclear factor kappaB and mitogen-activated protein kinase pathways. Mutations that truncate and inactivate the carboxyl-terminal deubiquitinating domain of CYLD underlie the development of skin appendage tumors in humans, whereas down-regulation of Cyld expression has been associated with the development of various types of human malignancies including lung cancer. To establish an animal model of human CYLD inactivation and characterize the biological role of CYLD in vivo, we generated mice carrying a homozygous deletion of Cyld exon 9 mice ) using a conditional approach. Our study identifies an important role of CYLD in lung maturation, which may underlie the development of many cases of lung cancer.

This surgery involves taking an\n artery from the scalp outside the skull, making a small hole in the skull and then connecting\n the scalp artery to a brain artery inside the skull. In this way the blockage of the carotid\n artery in the neck is bypassed and more blood can flow to the brain. In some people natural\n bypass arteries develop and the brain is already getting plenty of blood. These people have a\n low risk of stroke if they take medicine. In other people, no natural bypass arteries develop\n so less blood flows to their brains.

In order to determine if people fit into this second group of people who may\n benefit from the bypass operation they need to have a test called a PET scan.

The PET scan uses radioactive oxygen and water and is experimental (not\n approved by the United States Food and Drug Administration). If the PET scan shows that less\n blood is getting to the brain, there will be a 50-50 chance (like a coin toss) of receiving\n the bypass surgery or not. There will then be follow-up visits to the clinic one month later\n and then every three months for two years to check on the appropriate medical treatment that\n everyone will receive and to determine who has had a stroke.\n\n The study hypothesis is that extracranial-intracranial bypass surgery when added to best\n medical therapy can reduce by 40 percent subsequent stroke within two years in participants\n with recent TIA ('ministroke\") or stroke (</= 120 days) due to blockage of the carotid artery\n and reduced blood flow to the brain measured by PET.\n " }, { "p": "http://data.linkedct.org/resource/linkedct/summary", "s": "http://data.linkedct.org/resource/trials/NCT00029146", "o": "\n The purpose of this study is to determine if extracranial-intracranial bypass surgery when\n added to best medical therapy can reduce the subsequent risk of ipsilateral stroke in\n high-risk patients with recently symptomatic carotid occlusion and increased cerebral oxygen\n extraction fraction measured by PET.\n " } ]

Which proteins act as factors that promote transcription-coupled repair in bacteria?
[ "Transcription coupled nucleotide excision repair (TC-NER or TCR) is a cellular process by which UV-induced damage and other road-blocks encountered in the transcribed strand are restored. Bacterial transcription-coupled repair is initiated when RNA polymerase stalled at a DNA lesion is removed by Mfd (Mutation frequency decline), an ATP-dependent DNA translocase. Mfd is the major transcription repair coupling factor in bacteria. Also, the transcription elongation factor NusA, in addition to its role in recruiting translesion synthesis (TLS) DNA polymerases to gaps encountered during transcription, promotes an alternative class of TCR involved in the identification and removal of a class of lesion, such as the N(2)-f-dG lesion." ]
[ "Mfd", "NusA" ]
[ "Transcription-coupled repair (TCR) is a cellular process by which some forms of DNA damage are repaired more rapidly from transcribed strands of active genes than from nontranscribed strands or the overall genome. In humans, the TCR coupling factor, CSB, plays a critical role in restoring transcription following both UV-induced and oxidative DNA damage.

What is the association between Generalized anxiety disorder and mortality risk?
[ "Numerous studies have demonstrated that Generalized anxiety disorder is associated with increased mortality risk in different populations, including veterans and non demented elderly individuals. Anxiety disorders predict greater mortality, particularly when present with other psychiatric disorders. However, one study has found that generalized anxiety disorder was not associated with excess mortality in depressive elderly people." ]

[ "RESULTS: MDD and GAD were positively and significantly associated with all-cause and CVD mortality. The relationships between MDD and GAD and CVD mortality were no longer significant after adjustment for sociodemograhics, health status at entry, health behaviors, and other risk markers. ", "In analyses comparing comorbidity and GAD and MDD alone, with neither diagnosis, comorbidity proved to be the strongest predictor of both all-cause and CVD mortality.

Is there a crystal structure of the full-length of the flaviviridae NS5(Methyltransferase - RNA depended RNA Polymerase) ?
[ "Yes, there is the crystal Structure of the full-length Japanese encephalitis virus (Flaviviridae) NS5 - PDB:4K6M" ]
[ "yes" ]
[ " flavivirus NS5 harbors a methyltransferase (MTase) in its N-terminal ≈ 265 residues and an RNA-dependent RNA polymerase (RdRP) within the C-terminal part. One of the major interests and challenges in NS5 is to understand the interplay between RdRP and MTase as a unique natural fusion protein in viral genome replication and cap formation. Here, we report the first crystal structure of the full-length flavivirus NS5 from Japanese encephalitis virus. ", "(DENV) nonstructural protein 5 (NS5) is composed of two globular domains separated by a 10-residue linker. The N-terminal domain participates in the synthesis of a mRNA cap 1 structure ((7Me)GpppA(2'OMe)) at the 5' end of the viral genome and possesses guanylyltransferase, guanine-N7-methyltransferase, and nucleoside-2'O-methyltransferase activities. The C-terminal domain is an RNA-dependent RNA polymerase responsible for viral RNA synthesis. Although crystal structures of the two isolated domains have been obtained, there are no structural data for full-length NS5. It is also unclear whether the two NS5 domains interact with each other to form a stable structure in which the relative orientation of the two domains is fixed. To investigate the structure and dynamics of DENV type 3 NS5 in solution, we conducted small-angle X-ray scattering experiments with the full-length protein. NS5 was found to be monomeric and well-folded under the conditions tested.", "West Nile virus (WNV) NS5 protein contains a methyltransferase (MTase) domain involved in RNA capping and an RNA-dependent RNA polymerase (RdRp) domain essential for virus replication. Crystal structures of individual WNV MTase and RdRp domains have been solved; however, the structure of full-length NS5 has not been determined. To gain more insight into the structure of NS5 and interactions between the MTase and RdRp domains, we generated a panel of seven monoclonal antibodies (mAbs) to the NS5 protein of WNV (Kunjin strain) and mapped their binding sites using a series of truncated NS5 proteins and synthetic peptides. Binding sites of four mAbs (5D4, 4B6, 5C11 and 6A10) were mapped to residues 354-389 in the fingers subdomain of the RdRp. This is consistent with the ability of these mAbs to inhibit RdRp activity in vitro and suggests that this region represents a potential target for RdRp inhibitors. Using a series of synthetic peptides, we also identified a linear epitope (bound by mAb 5H1) that mapped to a 13 aa stretch surrounding residues 47 and 49 in the MTase domain, a region predicted to interact with the palm subdomain of the RdRp. The failure of one mAb (7G6) to bind both N- and C-terminally truncated NS5 recombinants indicates that the antibody recognizes a conformational epitope that requires the presence of residues in both the MTase and RdRp domains.

What is the role of necroptosis in cancer therapy?
[ "Necroptosis, a novel form of programmed cell death (PCD), is caspase independent but RIPK and RIPK3 dependent. The apoptotic, autophagic and necroptotic pathways of PCD were shown to be interconnected, with molecules such as FLIP acting as a bridge between them. Therefore, simultaneous activation of the three PCD pathways would make cancer therapy more effective, whereas induction of necroptosis could be an alternative, in cases where apoptosis-inducing cancer chemotherapy is not effective. For example, inhibition of GSK3B was found to bypass drug resistance of p53-null colon carcinomas by enabling necroptosis in response to 5-FU treatment." ]

Are epigenetic modifications implicated in cardiovascular development and disease?
[ "Genetic and epigenetic factors are of great importance in cardiovascular biology and disease. Aberrant epigenetic mechanisms may lead to pathological consequences such as cardiovascular disease (CAD).Recent studies have greatly expanded our understanding of the regulation of cardiovascular development at the chromatin level, including the remodeling of chromatin and the modification of histones. Thus, understanding chromatin-level regulation will allow for a better appreciation of gene regulation as a whole and may set a fundamental basis for cardiovascular disease." ]
[ "yes" ]
[ "Gene expression regulation through the interplay of DNA methylation and histone modifications is well-established, although the knowledge about the function of epigenetic signatures in cardiovascular disease is still largely unexplored.", "The study of epigenetic markers is, therefore, a very promising frontier of science which may aid in a deeper understanding of molecular mechanisms underlying the modulation of gene expression in the biomolecule pathways linked to cardiovascular diseases.", "This review highlights our current knowledge of epigenetic gene regulation and the evidence that chromatin remodeling and histone modifications play key roles in the pathogenesis of cardiovascular disease through (re)programming of cardiovascular (stem) cells commitment, identity and function.", "Notably, multiple subunits of switching defective/sucrose non-fermenting (SWI/SNF) chromatin-remodeling complexes have been identified as strong candidates underlying these defects because they physically and functionally interact with cardiogenic transcription factors critical to cardiac development, such as TBX5, GATA-4, and NKX2-5. While these studies indicate a critical role of SWI/SNF complexes in cardiac development and congenital heart disease, many exciting new discoveries have identified their critical role in the adult heart in both physiological and pathological conditions involving multiple cell types in the heart, including cardiomyocytes, vascular endothelial cells, pericytes, and neural crest cells.", "Recent studies have greatly expanded our understanding of the regulation of cardiovascular development at the chromatin level, including the remodeling of chromatin and the modification of histones. Chromatin-level regulation integrates multiple inputs and coordinates broad gene expression programs. Thus, understanding chromatin-level regulation will allow for a better appreciation of gene regulation as a whole and may set a fundamental basis for cardiovascular disease.", "Genetic and epigenetic factors are of great importance in cardiovascular biology and disease. Tobacco-smoking, one of the most important cardiovascular risk factors, is itself partially determined by genetic background and is associated with altered epigenetic patterns.", "Epigenetic modifications, including DNA methylation, histone modification (acetylation, methylation and phosphorylation) and miRNA, are critical for regulating developmental events. However, aberrant epigenetic mechanisms may lead to pathological consequences such as cardiovascular disease (CAD), neurodegenerative disease, obesity, metabolic disorder, bone and skeletal diseases and various cancers.", "Cardiovascular disease pathways are now being approached from the epigenetic perspective, including those associated with atherosclerosis, angiogenesis, ischemia-reperfusion damage, and the cardiovascular response to hypoxia and shear stress, among many others. With increasing interest and expanding partnerships in the field, we can expect new insights to emerge from epigenetic perspectives of cardiovascular health.", "Epigenetic modifications are heritable alterations of the genome, which can govern gene expression without altering the DNA sequence. The purpose of this review is to render an overview of the possible mechanisms of epigenetic regulation of gene expression in response to environmental pollutants leading to cardiovascular diseases (CVD).", "From varied study approaches directed either toward the general understanding of the key pathway regulatory genes, or sampling population cohorts for global and gene-specific changes, it has been possible to identify several epigenetic signatures of environmental exposure relevant to CVD.", "An understanding of chromatin remodelling in response to environmental stimuli conducive to CVD is emerging, with the promise of novel diagnostic and therapeutic candidates.", "Consolidated knowledge is accumulating as to the role of epigenetic regulatory mechanisms in the physiology of vascular development and vascular tone as well as in the pathogenesis of cardiovascular disease. The modulation of gene expression through modification of the epigenome by structural changes of the chromatin architecture without alterations of the associated genomic DNA sequence is part of the cellular response to environmental changes. Such environmental conditions, which are finally being translated into adaptations of the cardiovascular system, also comprise pathological conditions such as atherosclerosis or myocardial infarction. ", "Emerging data suggest that these epigenetic modifications also impact on the development of cardiovascular disease. Histone modifications lead to the modulation of the expression of genetic information through modification of DNA accessibility. In addition, RNA-based mechanisms (e.g., microRNAs and long non-coding RNAs) influence the development of disease.", "We here outline the recent work pertaining to epigenetic changes in a cardiovascular disease setting.", "Epigenetics may represent one of the possible scientific explanations of the impact of such intrauterine risk factors for the subsequent development of cardiovascular disease (CVD) during adulthood.", "Epigenetic mechanisms include DNA methylation, histone modification, and microRNA alterations, which collectively enable the cell to respond quickly to environmental changes. A number of CVD risk factors, such as nutrition, smoking, pollution, stress, and the circadian rhythm, have been associated with modification of epigenetic marks. Further examination of these mechanisms may lead to earlier prevention and novel therapy for CVD.", " Emerging data suggest that these epigenetic modifications also impact on the development of cardiovascular disease.", "Emerging data suggest that these epigenetic modifications also impact on the development of cardiovascular disease.", "Epigenetic alterations are associated with inflammation and cardiovascular disease in patients with chronic kidney disease.", "Emerging data suggest that these epigenetic modifications also impact on the development of cardiovascular disease", "Epigenetic mechanisms that underpin metabolic and cardiovascular diseases.", "Epigenetic regulation of cardiovascular differentiation.", "Epigenetic control mechanisms play a key role in the regulation of embryonic development and tissue homeostasis and modulate cardiovascular diseases." ]

Why does the prodrug amifostine (ethyol) create hypoxia?

", "However, amifostine has also been described as a potent hypoxia-mimetic compound and as a strong p53 inducer; both effects are known to potently modulate vascular endothelial growth factor (VEGF-A) expression. The angiogenic properties of this drug have not been clearly defined.", "Both dose fractionation and amifostine protect osteoblasts from the growth inhibitory effects of ionizing radiation. Fractionation but not amifostine was protective for hypoxia-induced vascular endothelial growth factor production (used as a surrogate marker of normal osteoblast function)", "Radioprotective modalities such as dose fractionation and pharmacologic agents such as amifostine have been used to protect bone and other types of normal tissue from the damaging effects of ionizing radiation without significantly impacting tumor kill. To better understand the cellular mechanism of radioprotection of osseous tissue, the authors sought to determine the effect of dose fractionation and amifostine on isolated osteoblasts", "Tumor hypoxia and low intrinsic radiosensitivity may counteract the efficacy of standard radiotherapy for locally advanced head and neck cancer (HNC).

Whether HIF2alpha expressing tumors are more sensitive to larger radiotherapy fractions, compared to standard radiotherapy fractionation, is an issue that deserves further investigation.", "Amifostine has been shown to specifically protect normal tissues from damage caused by radiation and chemotherapy. An inactive prodrug, amifostine is converted to an active thiol by dephosphorylation by alkaline phosphatase in the normal endothelium. The hypovascularity and acidity of the tumor environment and the differential expression of alkaline phosphatase in normal and neoplastic tissues contribute to its cytoprotective selectivity. The cytoprotective mechanism of amifostine is complicated, involving free-radical scavenging, DNA protection and repair acceleration, and induction of cellular hypoxia.", "We investigated additional cytoprotective pathways involving intracellular hypoxia and the activation of the hypoxia-inducible factor (HIF) pathway, a key transcription factor regulating glycolysis, angiogenesis and apoptosis, which is also linked with radioresistance", " tumor hypoxia and ability of cancer cells to undergo rapid repopulation during radiotherapy are associated with failure of radiotherapy. Tumors with low alpha/beta-ratio values or hypoxic tumors unable to undergo re-oxygenation, are unlikely to be eradicated with standard radiotherapy. Although the therapeutic efficacy of accelerated regimens based on low-dose per fraction may be high since they minimize the adverse role of rapid tumor repopulation, the cellular compartment with low alpha/beta-ratio values (i.e. hypoxic cells) remains a limiting factor.

What is the role of lysine-specific demethylase 1 (LSD1) in hematopoiesis?
[ "LSD1 represents a central regulator of hematopoietic stem and progenitor cells. LSD1 knockdown (LSD1-kd) expanded progenitor numbers by enhancing their proliferative behavior. LSD1-kd led to an extensive expansion of granulomonocytic, erythroid and megakaryocytic progenitors. In contrast, terminal granulopoiesis, erythropoiesis and platelet production were severely inhibited. The only exception was monopoiesis, which was promoted by LSD1 deficiency. Importantly, we showed that peripheral blood granulocytopenia, monocytosis, anemia and thrombocytopenia were reversible after LSD1-kd termination. Extramedullary splenic hematopoiesis contributed to the phenotypic reversion, and progenitor populations remained expanded. LSD1-kd was associated with the upregulation of key hematopoietic genes, including Gfi1b, Hoxa9 and Meis1, which are known regulators of the HSC/progenitor compartment. We also demonstrated that LSD1-kd abrogated Gfi1b-negative autoregulation by crossing LSD1-kd with Gfi1b:GFP mice. There is also epigenetic regulation of hematopoietic differentiation by Gfi-1 and Gfi-1b that is mediated by the cofactors CoREST and LSD1. A short Gfi-1B isoform controls erythroid differentiation by recruiting the LSD1-CoREST complex through the dimethylation of its SNAG domain. The enzymatic domain of LSD1 plays an important role in repressing the TAL1-directed transcription of GAL4 reporter linked to a thymidine kniase minimal promoter. Furthermore, the TAL1-associated LSD1, HDAC1, and their enzymatic activities are coordinately down-regulated during the early phases of erythroid differentiation. Consistent with the rapid changes of TAL1-corepressor complex during differentiation, TAL1 recruits LSD1 to the silenced p4.2 promoter in undifferentiated, but not in differentiated, murine erythroleukemia (MEL) cells. ShRNA-mediated knockdown of LSD1 in MEL cells resulted in derepression of the TAL1 target gene accompanied by increasing dimeH3K4 at the promoter region. Thus, it appears that histone lysine demethylase LSD1 may negatively regulate TAL1-mediated transcription and that the dynamic regulation of TAL1-associated LSD1/HDAC1 complex may determine the onset of erythroid differentiation programs. Furthermore, RUNX1 has been shown to be part of a large transcription factor complex, together with LDB1, GATA1, TAL1, and ETO2 in erythroid cells. RUNX1 interacts with LSD1 and MYEF2 in erythroid cells. MYEF2 is bound in undifferentiated cells and is lost upon differentiation, whereas LSD1 is bound in differentiated cells. Finally, LSD1 also participates in the trans-repressive effects of SALL4. Based on luciferase assays, the amine oxidase domain of LSD1 is important in suppressing SALL4-mediated reporter transcription. In freshly isolated adult mouse bone marrows, both SALL4 and LSD1 proteins are preferentially expressed in undifferentiated progenitor cells and co-localize in the nuclei. Further sequential chromatin immunoprecipitation assay confirmed that these two factors share the same binding sites at the promoter regions of important hematopoietic regulatory genes including EBF1, GATA1, and TNF." ]

How are induced pluripotent stem cells used in the study and treatment of cardiovascular diseases?
[ "The major goal within the field of cardiovascular regenerative medicine is to replace lost or damaged cardiac muscle and coronaries following ischaemic disease. At present, de novo cardiomyocytes can be generated either in vitro, using directed differentiation of embryonic stem cells or induced pluripotent stem cells, or in vivo via direct reprogramming of resident adult cardiac fibroblast or ectopic stimulation of resident cardiac stem or progenitor cells. The production of human cardiac progenitor cells and cardiomyocytes from human pluripotent stem cells provides an amenable source of cells for applications in drug discovery, disease modeling, regenerative medicine, and cardiotoxicity screening. In addition, the ability to derive human-induced pluripotent stem cells from somatic tissues, combined with current high-throughput screening and pharmacogenomics, may help realize the use of these cells to fulfill the potential of personalized medicine. Human induced pluripotent stem cells (iPSC) provide a unique opportunity to study \"disease in a dish\" within a defined genetic and environmental background. Patient-derived iPSCs have been successfully used to model cardiomyopathies, rhythm disorders and vascular disorders. Long-QT syndrome and catecholaminergic polymorphic ventricular tachycardia are two heart rhythm disorders that have been already successfully modeled by several groups using this approach, which will likely serve to model other mono- or polygenetic cardiovascular disorders in the future. The use of iPSC-derived cardiomyocytes to study genetic cardiovascular disorders will enable a deeper and more applicable understanding of the molecular mechanisms of human disease, as well as improving our ability to achieve successful cell-based therapies." ]

Finally, the iPSC technology may enable personalized cell therapies, while avoiding the ethical concerns surrounding human embryonic stem cells.

Transplantation of cardiomyocytes derived from human pluripotent stem cells has the potential to alleviate heart disease. Since the initial derivation of human embryonic stem cells, significant progress has been made in the generation and characterization of enriched cardiomyocytes and the demonstration of the ability of these cardiomyocytes to survive, integrate, and function in animal models. The scope of therapeutic potential from pluripotent stem cell-derived cardiomyocytes has been further expanded with the invention of induced pluripotent stem cells, which can be induced to generate functional cardiomyocytes for regenerative cardiac therapy in a patient specific manner.
