MicroRNAs (miRNAs) are small, non-coding RNAs that regulate gene expression by targeted repression of transcription and translation. In this study we show that miRNA-23b (miR-23b) acts as a tumor suppressor in bladder cancer. Quantitative real-time PCR analysis showed that miR-23b is significantly down-regulated in bladder cancer cell lines and tumor tissues compared to non-malignant cells and ...
The miRNAs have great potential as biomarkers and therapeutic agents owing to their ability to control multiple genes and potential to influence cellular behavior. Here, we identified that miR-23b is a methylation-silenced tumor suppressor in prostate cancer. We showed that miR-23b expression is controlled by promoter methylation and has great promise as a diagnostic and prognostic biomarker in...
BACKGROUND Diabetes mellitus (DM) has multifactorial detrimental effects on myocardial tissue. Recently, carbonic anhydrases (CAs) have been shown to play a major role in diabetic microangiopathy but their role in the diabetic cardiomyopathy is still unknown. METHODS AND RESULTS We obtained left ventricular samples from patients with DM type 2 (DM-T2) and nondiabetic (NDM) patients with posti...
BACKGROUND Skin grafting with the preservation of denatured dermis is a novel strategy for the treatment of burn-injured skin. Denatured dermis has the ability to restore to the morphology and function of normal skin, but the underlying molecular mechanism is elusive. MicroRNAs (miRNA) are small noncoding RNAs and regulate normal physiology as well as disease development. In this study, we asse...
Diabetic nephropathy (DN) is a frequent and severe complication of diabetes that is structurally characterized by glomerular basement membrane thickening, extracellular matrix accumulation, and destabilization of podocyte foot processes. MicroRNAs (miRNAs) are dysregulated in DN, but identification of the specific miRs involved remains incomplete. Here, we confirm that the peripheral blood from...
BACKGROUND Gastric cancer (GC) is a common malignant disease and microRNAs (miRNAs) have been shown to play important roles in GC tumorigenesis. As the clinical outcome of GC is closely correlated with the clinical stage at the time of diagnosis, early detection and prevention are crucial. This study was designed to evaluate the expression level of plasma miR-23b in patients with GC and investi...
سلول های بنیادی مزانشیمی سلول هایی هستند که می توانند فعال سازی سلول های دندریتیک را تنظیم و ویژگی های تولرژنیک را در سلول های دندریتیک القا کنند. تمام مکانیسم های دخیل در القا خواص تولرژنیک در سلول های دندریتیک هنوز به طور کامل شناخته نشده اند. microrna ها (mir) نقش مهمی در بلوغ و عملکرد سلول های دندریتیک بازی میکنند. در این مطالعه ما اثرات سوپ رویی سلول های بنیادی مزانشیمی را بر بیان mir-155 ...
BACKGROUND MicroRNAs (miRNAs) are small, single-stranded, noncoding RNAs, which usually bind to the 3'-untranslated region of target mRNAs and are capable of inducing posttranscriptional gene regulation by blocking translation or by degrading the target mRNA. However, the expression level of miR-23 in radiation induced carcinogenesis is largely unknown. METHODS Radiation induced thymic lympho...
Objective(s): Osteoarthritis (OA), characterized by degradation of articular cartilage, is a leading cause of disability. As the only cell type present in cartilage, chondrocytes play curial roles in the progression of OA. In our study, we aimed to explore the roles of miR-23b in the lipopolysaccharide (LPS)-induced inflammatory injury. Materials and Methods: LPS-induced cell injury of ATDC5 ce...
Proline oxidase (POX) is a novel mitochondrial tumor suppressor, which can suppress proliferation and induce apoptosis through the generation of reactive oxygen species (ROS) and decreasing hypoxia inducible factor (HIF) signaling. Recent studies have demonstrated the absent expression of POX in human cancer tissues, including renal cancer. However, the mechanism for the loss of POX remains obs...
