ANRIL may be involved in the progression and development of T2DM-MI, which might provide novel ideas for the prevention and treatment of cardiovascular diseases.
Cyclin-dependent kinase inhibitor 2B antisense RNA 1 (CDKN2B-AS1) is a significant susceptibility locus for cardiovascular disease by regulating inflammation response and cell cycle.
Several genetic-polymorphisms have been identified in this region that are highly associated with CVD, and these are clustered around the gene loci for CDKN2B (coding for p15ink4b), CDKN2A (coding for p16ink4a and p14ARF) and the 3' end of CDKN2BAS, which has been termed antisense noncoding RNA in the INK4 locus (ANRIL).
We assessed genetic associations with clinical and subclinical cardiovascular disease, risk factor phenotypes, and gene expression levels of the protein-coding genes CDKN2A and CDKN2B and the noncoding gene ANRIL in freshly harvested leukocytes and platelets.
Our results suggest that ANRIL splicing variants play a role in coordinating tissue remodeling, by modulating the expression of genes involved in cell proliferation, apoptosis, extra-cellular matrix remodeling and inflammatory response to finally impact in the risk of cardiovascular disease and other pathologies.
Recent studies showed that single nucleotide polymorphisms mapping in the vicinity of ANRIL are linked to a wide spectrum of conditions, including cardiovascular disease, ischemic stroke, type 2 diabetes, frailty and Alzheimer's disease.
