BACKGROUND: Atherosclerosis is a chronically inflammatory disease and one of the
leading causes of deaths worldwide. Endothelial cell apoptosis plays a crucial
role in its development. Several microRNAs (miRNAs) are reportedly involved in
atherosclerotic plaque formation, including miRNA-210 (miR-210). However, the
underlying mechanism of its role in endothelial cell apoptosis during
atherosclerosis is still largely unknown. METHODS: A mouse model with
atherosclerosis induced by a high-fat diet (HFD) was built in ApoE (-/-) mice.
The levels of endothelial cell apoptosis were determined via flow cytometry. The
expressions of miR-210 and PDK1 in purified CD31+ endothelial cells from mouse
aorta were measured via RT-qPCR and western blot. Binding between miR-210 and the
3'-untranslated region (UTR) of PDK1 mRNA was predicted using bioinformatics
analyses and confirmed with a dual luciferase reporter assay. The effects of
miR-210 were further analyzed in an in vitro model using human aortic endothelial
cells (HAECs) treated with oxidized low-density lipoprotein (ox-LDL). RESULTS: We
found that the HFD mice developed atherosclerosis in 12 weeks and had a
significantly higher percentage of endothelial cell apoptosis. The upregulated
level of miR-210 in the HFD mice and HAECs inversely correlated with the level of
PDK1. Inhibiting miR-210 expression significantly reduced HAEC apoptosis, as
evidenced by the results of the MTT and flow cytometry experiments. Further
analysis identified PDK1 as the target of miR-210 and showed that PDK1
overexpression reversed the pro-apoptotic effect of miR-210 through mediation of
the P13K/Akt/mTOR pathways. CONCLUSION: Our study suggests a novel role for
miR-210 in the progression of atherosclerosis through the regulation of
endothelial apoptosis. This indicates that miR-210 might have potential in
treatment of atherosclerosis.
