SPOTLIGHT REVIEW MicroRNAs in control of cardiac hypertrophy
نویسندگان
چکیده
MicroRNAs refer to a subfamily of small non-coding RNA species that are designed to influence gene expression in nearly all cell types studied to date. Studies from the past decade have demonstrated that microRNAs are atypically expressed in the cardiovascular system under specific pathological conditions. Gainand loss-of-function studies using in vitro and in vivo models have revealed distinct roles for specific microRNAs in cardiovascular development, physiological functions, and cardiac pathological conditions. In this review, the current relevant findings on the role of microRNAs in cardiac hypertrophic growth are updated, the target genes of these microRNAs are summarized, and the future of microRNAs as potential therapeutic targets is discussed.

SPOTLIGHT REVIEW Role of microRNAs in the reperfused myocardium towards post-infarct remodelling
Myocardial ischaemia/reperfusion (I/R)-induced remodelling generally includes cell death (necrosis and apoptosis), myocyte hypertrophy, angiogenesis, cardiac fibrosis, and myocardial dysfunction. It is becoming increasingly clear that microRNAs (miRNAs or miRs), a group of highly conserved small ( 18–24 nucleotide) non-coding RNAs, fulfil specific functions in the reperfused myocardium towards ...

Background and Objective: In this study the effect of high intensity interval training on miR-29 expression that is expressed in the heart and in the regulation of physiological processes, including extracellular matrix and cardiac hypertrophy of healthy male rats were examined. Materials and Methods: 16 Wistar rats were divided into training (n=8) and control (n=8) groups. After one week of fa...
متن کاملInsights into role of microRNAs in cardiac development, cardiac diseases, and developing novel therapies
Objective(s): MicroRNAs (miRNAs) are a subfamily of small noncoding RNAs that play a variety of roles in regulating gene expression in nearly all organisms. They affect different biological pathways by post-transcriptionally regulating mRNAs. Aside from miRNAs’ role in maintaining cellular homeostasis, their perturbation is related to several pathologic states and dis...
متن کاملDynamic changes of hemodynamic parameters and cardiac transcription of sirtuins in adaptive and mal-adaptive phases of pressure overload-induced hypertrophy in rats
Introduction: The aim of the study was to investigate the structural and hemodynamic changes as well as cardiac transcriptional profile of the key regulatory proteins, sirtuins family (SIRT1-7), in adaptive and mal-adaptive phases of left ventricular hypertrophy (LVH). Methods: LVH was induced in male Wistar rats (190±20g) by abdominal aortic banding. The third and sixteenth weeks post-surgery ...
متن کاملSPOTLIGHT REVIEW Proteasome inhibitors and cardiac cell growth
Activation of the ubiquitin-proteasome system has been described in different models of cardiac hypertrophy. Cardiac cell growth in response to pressure or volume overload, as well as physiological adaptive hypertrophy, is accompanied by an increase in protein ubiquitination, proteasome subunit expression, and proteasome activity. Importantly, an inhibition of proteasome activity prevents and r...
