Translocation-associated Notch homologue (TAN-1), a gene originally cloned from the translocation breakpoint of a human T cell leukemia carrying a 9:7(q34.3) translocation, encodes a protein belonging to the Notch/Lin-12/Glp-1 receptor family. These receptors mediate the specification of numerous cell fates during development in invertebrates and vertebrates. The intracellular portion of Notch/...
Nuclear factor-kappaB (NF-kappaB) has been recognized to play a critical role in cell survival and inflammatory processes. It has become a target for intense drug development for the treatment of cancer, inflammatory, and autoimmune diseases. Here, we describe a potent NF-kappaB inhibitor, eriocalyxin B (Eri-B), an ent-kauranoid isolated from Isodon eriocalyx, an anti-inflammatory remedy. The p...
Lipopolysaccharide (LPS) is one of the most potent trigger substances for monocytes and macrophages causing secretion of tumor necrosis factor alpha (TNF-alpha) and other inflammatory mediators. The nature of the nuclear factors involved in human TNF-alpha gene regulation is still unknown. Nuclear factor kappa B (NF-kappa B) proteins have been suggested to play an important role in gene transcr...
MicroRNAs (miRNAs) have negative effects on gene expression and are major players in cell function in normal and pathological conditions. Epstein-Barr virus (EBV) infection of resting B lymphocytes results in their growth transformation and associates with different B cell lymphomas. EBV-mediated B cell transformation involves large changes in gene expression, including cellular miRNAs. We perf...
Rel and nuclear factor (NF)-kappaB1, two members of the Rel/NF-kappaB transcription factor family, are essential for mitogen-induced B cell proliferation. Using mice with inactivated Rel or NF-kappaB1 genes, we show that these transcription factors differentially regulate cell cycle progression and apoptosis in B lymphocytes. Consistent with an increased rate of mature B cell turnover in naive ...
Nuclear factor-kappa B (NF-?B) induces the expression of many pro-inflammatory genes, including cytokines and chemokines. In past decades, a wealth clinical as well animal model-based studies have demonstrated association deregulated NF-?B signaling pathway with progression various inflammatory diseases, bowel disease (IBD), multiple sclerosis (MS), chronic obstructive pulmonary (COPD). Given c...
Yes-associated protein (YAP) regulates numerous cellular homeostasis processes and malignant transformation. We found that YAP influences ZO-1-mediated cell migration using E-cadherin-restored EC96 cells derived from gastric AGS cells. Ectopic expression of E-cadherin enhanced straightforward cells, in comparison to the meandering movement parental In ZO-1 increased but nuclear levels activity ...
نوروبلاستوما فراوان ترین تومور جامد در کودکان می باشد. رویکردهای درمانی کنونی در مورد نوروبلاستوما اثر چندانی بر بهبود بیماری نداشته و بنابراین، مطرح نمودن رویکردهای درمانی جدید در مورد این بیماری از اهمیت زیادر برخوردار است. در این تحقیق، اثر سیلیبینین، که به عنوان یک عامل درمانی نوین در بسیاری از سرطان ها مطرح است، بر رده های سلولی sk-n-mc و sk-n-be(2) نوروبلاستوما مورد بررسی قرار گرفت. نتایج...
Auto-reactive B lymphocytes and its abnormal CD40 signaling play important roles in the pathogenesis of systemic lupus erythematosus (SLE). In this study, we analyzed CD40 expression and CD40/CD154 induced activation of NF-κB signaling pathway in B cells from SLE patients. B cells from healthy volunteers and tonsilar B cells from chronic tonsillitis were used as negative and positive controls. ...
