Regulation of microRNAs in cell signaling pathways-mediated vascular remodeling

摘要

Vascular remodeling,which can be found in atherosclerosis,restenosis after angioplasty,hypertension,and some other frequent and serious chronic diseases.Smooth muscle cell(SMC)phenotype change,which has been described as converting from a contractile state into a synthetic phenotype,is a crucial event during vascular remodeling.Recently,micro RNAs(mi RNAs)a kind of small non-coding RNA molecules,has been proven to target critical genes of cell signaling pathways to regulate SMC phenotypic change.By searching the Pub Med,Embase,reviews,and reference listsof relevant papers,we systematically carried out a review of the literature to provide an overview of the mi RNAs and their target genes in cell signaling pathways,focus inthe pathways involving in SMC phenotype change.To be specific,mi RNAs that regulate genes involved in the MAPK signaling pathways(such as:mi R-155,mi R-92a,mi R-424/503,mi R-133,mi R-181b,mi R-31,mi R-1298,mi R-132,mi R-200c and mi R-483-3p),mi RNAs target genes involved in the TGF-βsignaling pathways(including mi R-24,mi R-17/92 cluster,mi R-599,mi R-21 and mi R-143/145),mi RNAs target the genes involved in the AMPK signaling pathways including mi R-144/451 and mi R-195,mi RNAs target the genes involved in the PI3K-Akt signaling pathways(including mi R-138,mi R-34c,mi R-223,mi R-761,mi R-10a,mi R-146a),mi R-199a-5ptargets the genes involved in the Wnt signaling pathways mi RNAs(mi R-221/222,mi R-15b,mi R-24/29a,mi R-224)involved in the PDGF signaling pathways and some mi RNAs(mi R-638,mi R-328,mi R-365,mi R-663,mi R-29b,mi R-130,mi R-142-5p,mi R-424/322)which regulate SMC phenotype change by other corresponding targets were in detailed discussed in our review.Exploring the regulation of miR NAs in key cellsignaling pathways-mediatedvascular remodeling wil have momentous impact on identifying novel therapeutic targets for its associated disease.
