Effect of trichostatin A on histone deacetylase 1 (HDAC 1) and CIP/KIP (p21CIP1/WAF1, p27KIP1, and p57KIP2) gene expression, cell growth inhibition and apoptosis induction in lung cancer COR-L105 cell line. Abstract Background: Lung cancer is one the leading cause of cancer-related death worldwide, with more than 1.2 million deaths each year. In addition to genetic mutations, epigenetic modif...
سابقه و هدف : در مطالعات مختلف بیان ژنهای کنترل کننده چرخه سلولی (p27 ,p53) و شاخص تکثیر (ki-67) در کانسر معده نتایج متفاوتی را با سرانجام بیماری و نیز با بعضی از شاخصه های کلینیکوهیستوپاتولوژیک نشان داده است. این مطالعه با هدف یافتن ارتباط بین بیان این مارکرها و شاخصه های هیستوپاتولوژیک در سرطان معده صورت گرفت.مواد و روشها : در این مطالعه تجربی (آزمایشگاهی) بلوکهای پارافینی 58 نمونه گاسترکتومی...
BACKGROUND Metformin is a widely used biguanide drug for the treatment of type 2 diabetes. It has been revaluated as a potential anti-cancer drug with promising activity in various tumors. However, the precise mechanisms underlying the suppression of cancer cells by metformin remain not well understood. MATERIAL AND METHODS In this study, human renal cell carcinoma cell line ACHN was used to in...
Ophiopogon japonicus is known to have various pharmacological effects. The present study investigated the effects of an extract of fermented Ophiopogon japonicas (FEOJ) on thrombin‑treated vascular smooth muscle cells (VSMCs). FEOJ treatment inhibited the proliferation of VSMCs treated with thrombin as indicated by an MTT assay. These inhibitory effects were associated with decreased phosphoryl...
AIMS Cyclins and other cell-cycle regulators have been used in several studies to regenerate cardiomyocytes in ischaemic heart failure. However, proliferation of cardiomyocytes induced by nuclear-targeted cyclin D1 (D1NLS) stops after one or two rounds of cell cycles due in part to accumulation of p27Kip1, an inhibitor of cyclin-dependent kinase (CDK). Thus, expression of S-phase kinase-associa...
PURPOSE Thiazolidinediones (TZDs) are known to inhibit the proliferation of vascular smooth muscle cell (VSMC) by increasing the activity of p27Kip1 and retinoblastoma protein (RB). However, the upstream signaling mechanisms associated with this pathway have not been elucidated. The Akt-mTOR-P70S6 kinase pathway is the central regulator of cell growth and proliferation, and increases cell proli...
The nuclear mitotic apparatus protein, NuMA, is involved in major cellular events such as DNA damage response, apoptosis and p53-mediated growth-arrest, all of which are under the control of the nucleolus upon stress. Proteomic investigation has identified NuMA among hundreds of nucleolar proteins. Yet, the precise link between NuMA and nucleolar function remains undetermined. We confirm that N...
