MicroRNA-125b in vascular diseases: An updated systematic review of pathogenetic implications and clinical applications
Abstract
Epigenetic changes, particularly non-coding RNAs, have been implicated extensively in the pathogenesis of vascular diseases. Specific miRNAs are involved in the differentiation, phenotypic switch, proliferation, apoptosis, cytokine production and matrix deposition of endothelial cells and/or vascular smooth muscle cells. MicroRNA-125b has been studied in depth for its role in carcinogenesis with a double-edged role; that is, it can act as an oncogene in some cancer types and as a tumour suppressor gene in others. However, cumulative evidence from the use of advanced miRNA profiling techniques and bioinformatics analysis suggests that miR-125b can be a potential mediator and useful marker of vascular diseases. Currently, the exact role of miR-125b in vascular diseases is not known. In this systematic review, we intend to provide an updated compilation of all the recent findings of miR-125b in vascular diseases, using a systematic approach of retrieving data from all available reports followed by data summarization. MiR-125b serves as a pathogenic player in multiple vascular pathologies involving endothelia and vascular smooth muscle cells and also serves as a diagnostic marker for vascular diseases. We further provide a computational biologic presentation of the complex network of miR-125b and its target genes within the scope of vascular diseases.
