Abstract

microRNAs (miRNAs) are a group of small non-coding RNA molecules known to regulate target genes at the post-transcriptional level. miRNAs are implicated in the regulation of multiple pathophysiological processes including dyslipidemia, a major risk factor for atherosclerosis. Emerging evidence suggests that miRNAs act as a novel class of epigenetic regulators of high-density lipoproteins cholesterol (HDL-C) from synthesis to clearance contributing remarkably to the pathogenesis of atherosclerosis. Accumulating studies have revealed that miRNAs such as miR-33, miR-27, miR-144, miR-758 and miR-20 are involved in the post-transcriptional control of ABCA1, ABCG1 and SCARB1 genes regulatory network of the reverse cholesterol transport (RCT). These miRNAs have been shown to be central players in the impairment of RCT pathway leading to the development of atherosclerosis. In this article, we present most recent understanding of involvement of relevant miRNAs in different steps of HDL metabolism and RCT pathway. We also discuss some of the actual limitations to the promise of these miRNAs and perspectives on their translation to clinical settings.

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.

Cancer Epigenetics & Metabolism (Keystone)

Epigenetic changes are present and dysregulated in many cancers, including DNA methylation, non-coding RNA segments and post-translational protein modifications. The epigenetic changes may or may not provide advantages for the cancer cells. This feed focuses on the relationship between cell metabolism, epigenetics and tumor differentiation.
