Abstract
MicroRNAs (miRNAs) are noncoding RNA molecules that play a significant role in atherosclerosis pathogenesis through post-transcriptional regulation. In the present work, a bioinformatic analysis using TargetScan and miRdB databases was performed to identify the miRNAs targeting three genes involved in foam cell atherosclerosis (CD36, Vav3, and SOCS1). A total number of three hundred and sixty-seven miRNAs were recognized and only miR-155-5p was selected for further evaluation based on Venn analysis. Another objective of this study was to evaluate the biological process and regulatory network of miR-155-5p associated with foam cell atherosclerosis using DIANA, DAVID, Cytoscape, and STRING tools. Additionally, the comprehensive literature review was performed to prove the miR-155-5p function in foam cell atherosclerosis. miR-155-5p might be related with ox-LDL uptake and endocytosis in macrophage cell by targeting CD36 and Vav3 genes which was showed from the KEGG pathways hsa04979, hsa04666, hsa04145 H, hsa04810, and GO:0099632, GO:0060100, GO:0010743, GO:001745. Furthermore, miR-155-5p was also predicted to increase the cholesterol efflux from macrophage by inhibit SOCS1 expression based on KEGG pathway hsa04120. Eleven original studies were included in the review and strongly suggest the role of miR-155-5p in foam cell atherosclerosis inhibition.
