مقدمه: micrornas (mirnas)، rnaهای کوچک تک رشته ای و غیر کد کننده ای می باشند که در تنظیم بیان ژن پس از رونویسی نقش دارند. micrornaها، نقش مهمی در فرایندهای مختلف سلولی شامل تکثیر سلولی، تمایز، چرخه ی سلولی، آپوپتوز و پیشرفت سرطان از طریق تنظیم منفی تومور ساپرسورها یا انکوژن ها ایفا می کنند. سرطان پستان، یکی از شایع ترین سرطان ها در دنیا می باشد. مطالعات نشان داده است که بیان mir-182 در سرطان پس...

Purpose microRNAs (miRs) are crucial intracellular mediators of various biological processes, also affecting the cardiovascular system. Recently, it has been shown that miRs circulate extracellularly in the bloodstream and that such circulating miRs change in response to physical activity. Therefore, the purpose of the current study was to investigate heart/muscle specific and inflammation rela...

Acute myocardial infarction (MI) involves necrotic and apoptotic loss of cardiomyocytes. One strategy to salvage ischemic cardiomyocytes is to modulate gene expression to promote cell survival without disturbing normal cardiac function. MicroRNAs (miRNAs) have emerged as powerful regulators of multiple cellular processes, including apoptosis, suggesting that regulation of miRNA function could s...

MicroRNA (miRNA) is a kind of short non-coding RNA, involved in various cellular processes. During keratinocyte differentiation, miRNAs act as important regulators. In this study, we demonstrated by microarray assay that the expression of miR-378b significantly increased during keratinocytes differentiation. Our findings showed that miR-378b could inhibit proliferation, migration and differenti...

RATIONALE During the transition from compensated hypertrophy to heart failure, the signaling between L-type Ca(2+) channels in the cell membrane/T-tubules and ryanodine receptors in the sarcoplasmic reticulum becomes defective, partially because of the decreased expression of a T-tubule-sarcoplasmic reticulum anchoring protein, junctophilin-2. MicroRNA (miR)-24, a junctophilin-2 suppressing miR...

miRNAs have emerged as important players in the regulation of gene expression and their deregulation is a common feature in a variety of diseases, especially cancer. Currently, many efforts are focused on studying miRNA expression patterns, as well as miRNA target validation. Here, we show that the over expression of miR-23a approximately 27a approximately 24-2 cluster in HEK293T cells induces ...

Individual microRNAs (miRNAs) are rapidly down-regulated during conditions of cellular activation and infection, but factors mediating miRNA turnover are poorly understood. Infection of mouse cells with murine cytomegalovirus (MCMV) induces the rapid down-regulation of an antiviral cellular miRNA, miR-27. Here, we identify a transcript produced by MCMV that binds to miR-27 and mediates its degr...

Background and aim The incidence of type 2 diabetes mellitus (T2DM) has increased worldwide. One the first actions to reduce risk this disease is implement healthy dietary models; however, no universal strategies have so far been established. In addition, MicroRNAs (miRNAs) are emerging as new biomarkers predict disease. We aimed study whether miRNAs could be used select nutritional therapy pre...

We previously found that remote ischemic perconditioning (RIPerc) was effective in attenuating myocardial injury during cardiac surgery. Given that microRNAs (miRs) act as an important player in ischemic/reperfusion (I/R) injury and apoptosis, this study aimed to investigate whether RIPerc reduces apoptosis in atrial myocardium and which apoptosis-related miRs are involved during valve replacem...
