This study investigated the role of microRNA-21 (miR-21) and microRNA-24 (miR-24) in the pathological processes that follow cerebral ischemic injury and examined the potential use of miR-21 and -24 in stroke diagnostics as sensitive plasma biomarkers. An oxygen-glucose deprivation (OGD) model was constructed using mouse N2A neuroblastoma cells (N2A). Western blot analysis and quantitative polym...
چکیده: سرطان معده یکی از علل مرگ ومیر در جهان و به خصوص در کشورهای آسیایی می باشد. میکرو rna ها،rna های کوچک غیر کد کننده به طول 20-24 نوکلئوتید هستند که در تنظیم بیان ژن بعد از رونویسی نقش دارند. میکرو rna ها قادر به اتصال به ناحیه ترجمه نشدنی 3 ژن هدف هستند. این اتصال سبب تخریب mrna یا مهار ترجمه می شود. میکرو rna های بسیاری تاکنون در سلول های انسانی شناسایی شده است که در مراحل مختلف رشد و نم...
MicroRNAs (miRNAs) are predicted to regulate approximately 30% of all human genes; however, only a few miRNAs have been assigned their targets and specific functions. Here we demonstrate that miR-24, a ubiquitously expressed miRNA, has an anti-proliferative effect independent of p53 function. Cell lines with differential p53 status were used as a model to study the effects of miR-24 on cell pro...
Cardiac fibrosis after myocardial infarction (MI) has been identified as a key factor in the development of heart failure. Although dysregulation of microRNA (miRNA) is involved in various pathophysiological processes in the heart, the role of miRNA in fibrosis regulation after MI is not clear. Previously we observed the correlation between fibrosis and the miR-24 expression in hypertrophic hea...
MicroRNAs (miRNAs) play an essential role in the development and progression of acute leukemia (AL). miR-24 promotes the survival of hematopoietic cells. However, little is known concerning the function of miR-24 in human AL. The aim of the present study was to investigate the clinical significance of miR-24 expression in AL. miR-24 expression in 147 patients with AL and 100 healthy individuals...
Abstract Circulating microRNA (miRNA), a non-coding RNA molecule, is the potential biomarker for bone and mineral metabolism. Primary hyperparathyroidism (PHPT) one of leading causes secondary osteoporosis. After parathyroidectomy, BMD improves as parathyroid hormone (PTH) decreases in patients with PHPT but degree recovery vary greatly among patients. Biomarkers which are able to predict posto...
MicroRNAs are known to play regulatory roles in gene expression associated with cancer development. We analyzed levels of the microRNA miR-24 in patients with breast carcinoma and found that miR-24 was higher in breast carcinoma samples than in benign breast tissues. We generated constructs expressing miR-24 and studied its functions using both in vitro and in vivo techniques. We found that the...
MicroRNAs (miRNAs) have been reported to have diverse biological roles in regulating many biological processes, including osteogenic differentiation. In the present study, we identified that miR-24 was a critical regulator during osteogenic differentiation. We found that overexpression of miR-24 significantly inhibited osteogenic differentiation, which decreased alkaline phosphatase activity, m...
