MiR-3571 modulates the proliferation and migration of vascular smooth muscle cells by targeting claudin 1.

ABSTRACT: Background and aims: The miRNA-based post-transcription modification has been extensively studied in hypertension. It however remains elusive how miRNA expression is regulated in this pathological process. We hypothesize that hydroxymethylation in the promoter regions tightly controls the levels of key miRNAs, which in turn affects the development of hypertension. Methods: The levels of hydroxymethylation in the promoter regions from thoracic aortic tissues were compared between spontaneously hypertensive rats (SHRs) and normotensive Wistar-Kyoto rats (WKYs), using hydroxymethylcytosine DNA immunoprecipitation (hMeDIP) sequencing. The altered hydroxymethylation level of miR-3571 was confirmed by glucosylation-coupled hydroxymethylation-sensitive qPCR. We further identified cl
