Abstract
Atherosclerosis is the leading risk factor for cardiovascular disease, in which vascular smooth muscle cell (VSMC) proliferation and apoptosis play an important role. Research has demonstrated that long non-coding RNAs (lncRNAs) are critical regulatory factors for VSMC function, however, the molecular mechanism leading to this pathology is still not fully understood. To explore this further, an ox-LDL induced VSMC model was established, in which lncRNA MEG8 expression was suppressed, while miR-181a-5p was enhanced in a dose- and time-dependent manner. Enhanced MEG8 expression suppressed the proliferation and migration ability of VSMCs, and induced apoptosis. Mechanically, MEG8 was found to promote the PPARα protein via sponging miR-181a-5p. Rescue experiments demonstrated that MEG8 and PPARα collectively regulate the proliferation, migration and apoptosis of VSMCs. Overall, this research illustrates that MEG8 regulates the proliferation and migration of VSMCs via the MEG8/miR-181a/PPARα axis.
