Mir-33 is a highly-conserved microRNA that is considered a potential target for atherosclerosis, since it has pro-atherogenic effects by directly targeting ABCA1 and ABCG1 cholesterol transporters, thus lowering HDL-cholesterol, and is involved in inflammatory processes and ER stress in atherosclerosis lesions [41,42]. This evidence concerns the gene ABCA1 and atherosclerosis.
