MicroRNA-214 modulates the senescence of vascular smooth muscle cells in carotid artery stenosis.

ABSTRACT:

Background

MicroRNAs control gene expression by post-transcriptional inhibition. Dysregulation of the expressions of miR-199a/214 cluster has been linked to cardiovascular diseases. This study aimed at identifying potential microRNAs related to vascular senescence.

Methods

Seven candidate microRNAs (miR-19a, -20a, -26b, -106b, - 126, - 214, and - 374) related to cell proliferation were tested for their expressions under CoCl₂-induced hypoxia in vascular smooth muscle cells (VSMCs). After identification of miR-214 as the candidate microRNA, telomere integrity impairment and cell cycle arrest were examined in VSMCs by using miR-214 mimic, AntagomiR, and negative controls. To investigate the clinical significance of miR-214 in vascular diseases, its plasma level from
