The knockdown of lncRNA myocardial infarction-associated transcript (MIAT) decreased the proliferation and migration of cultured human carotid artery smooth muscle cells (SMCs) through the regulation of the EGR1-ELK1-ERK pathway in atherosclerosis and carotid artery disease [55]; Ye et al. [56] reported MIAT as a miR-149-5p sponge to positively modulate the expression of anti-phagocytic molecule CD47, inhibiting efferocytosis in advanced atherosclerosis. This evidence concerns the gene CD47 and atherosclerosis.
