Genetic and environmental factors are involved in insulin resistance (IR). IR and dyslipidemia associate with increased risk of cardiovascular diseases. Plasma low-density lipoprotein cholesterol (LDL-C) level is a marker of cardiovascular risk. In a Caucasian general population we aimed at determining the multifactorial components of LDL-C levels using 10 genes and 3 phenotypes. In the PPARG, UCP3, ADIPOQ, TNF, LIPC, CARTPT, PCSK9, SCAP, SCARB1 and ENPP1 genes known to be associated with IR or dyslipidemia we genotyped 19 single nucleotide polymorphisms (SNPs) in 846 subjects. When several SNPs were genotyped for a given gene we constructed haplotypes. Including genetic and environmental variables (gender, body mass index (BMI) and adiponectin level) we used (1) the multifactor dimensionality reduction method to explain clusters of high and low LDL-C, and (2) the restricted partition method to explain LDL-C levels. Both methods showed that BMI and haplotypes at the ADIPOQ adiponectin encoding gene but not adiponectin level itself, were discriminant regarding to LDL-C. Subjects bearing an at-risk combination of BMI and ADIPOQ genotypes were prone to have a higher LDL-C (OR=3.13, 95% CI=2.20-4.46, P<0.0001). Our results suggest that in interaction with BMI, ADIPOQ haplotypes capture genetic variation(s) from neighboring gene(s) that would modulate LDL-C level.

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.
