LncRNA SCARNA8 promotes atherosclerotic plaque instability by inhibiting macrophage efferocytosis

In recent years, findings suggest that long noncoding RNAs (lncRNAs) are closely related to the development of atherosclerosis (AS), but there is a lack of studies on the involvement of lncRNA-regulated cytosolic burial in the regulation of AS. In this study, we investigated the mechanism by which l...

description In recent years, findings suggest that long noncoding RNAs (lncRNAs) are closely related to the development of atherosclerosis (AS), but there is a lack of studies on the involvement of lncRNA-regulated cytosolic burial in the regulation of AS. In this study, we investigated the mechanism by which lncRNA SCARNA8 affects macrophage cell burial to regulate AS. The cytosolic burial-associated target gene regulated by lncRNA SCARNA8 was PPARG. LncRNA SCARNA8 was increased in the carotid unstable plaque group, whereas PPARG was decreased. Ox-LDL led to the up-regulation of lncRNA SCARNA8 expression and apoptosis in Raw264.7 cells in a time-, concentration-dependent manner. Knockdown of lncRNA SCARNA8 upregulated PPARG and reduced apoptosis in Raw264.7 cells. In addition, knockdown of lncRNA SCARNA8 improved the stability of atherosclerotic plaques by promoting cellular burial of Raw264.7 cells. LncRNA SCARNA8 is a key regulator of plaque vulnerability, and targeting lncRNA SCARNA8 May provide a novel means for the prevention and treatment of AS.
