Abstract
Circ_0029589 and IGF2 were found to be upregulated while miR-424-5p was downregulated in vascular smooth muscle cells treated with oxidized low-density lipoprotein (ox-LDL).
- Silencing circ_0029589 reduced cell proliferation, migration, and invasion, and increased apoptosis in ox-LDL-treated vascular smooth muscle cells.
- MiR-424-5p was identified as a target of circ_0029589, and its knockdown reversed the effects of circ_0029589 interference on cell behavior.
- IGF2 was found to be a target of miR-424-5p, where its overexpression inhibited apoptosis and promoted cell proliferation, migration, and invasion.
- Circ_0029589 is associated with the regulation of IGF2 expression by acting as a sponge for miR-424-5p.
- These findings suggest that circ_0029589 silence may inhibit the progression of atherosclerosis through the miR-424-5p/IGF2 regulatory axis.
