With the aging of the population, the prevalence of calcific aortic valve disease (CAVD) has increased yearly. However, effective means to delay or even reverse the progression of CAVD are still lacking. This study revealed that prostate androgen-regulated mucin-like protein 1 (PARM1) expression was significantly up-regulated in calcified aortic valve tissues. Functional investigations demonstrated that PARM1 knockdown effectively suppressed osteogenic differentiation of valvular interstitial cells (VICs) and mitigated pathological aortic valve calcification. Mechanically, PARM1 knockdown down-regulated PRKCH mRNA expression, consequently attenuating MAPK pathway activation during the osteogenic differentiation of VICs. In conclusion, PARM1 could be a feasible target for CAVD prevention.
