SUMMARY:
(1) In atherosclerosis, levels of methyltransferases (‘writers’), binding proteins (‘readers’) and demethylases (‘erasers’) involved in methylations occurring in rRNA and mRNA are altered. The changes are accompanied by a marked downregulation of the well-known RNA modification N6-methyladenosine.
(2) NEIL3 affects vascular smooth muscle cells phenotypic identity, and could be a new player in atherosclerosis. Vascular smooth muscle cells accumulate DNA damage, which can promote plaque instability and lead to rupture and acute coronary heart disease. NEIL3 repairs damaged DNA.
