nature/cddisARTICLEOPENRho A/ROCK1 signaling-mediated metabolic reprogramming of valvular interstitial cells toward Warburg impact accelerates aortic valve calcification via AMPK/RUNX2 axisHuiruo Liu1,2,, Hang Yin1,two,, Zhen Wang1,2,3, Qiuhuan Yuan1,2,3, Feng Xu1,two,, Yuguo Chen1,2,and Chuanbao Li1,two,The Author(s)The aberrant differentiation of valvular interstitial cells (VICs) to osteogenic lineages promotes calcified aortic valves disease (CAVD), partly activated by potentially destructive hemodynamic forces. These involve Rho A/ROCK1 signaling, a mechano-sensing pathway. Nonetheless, how Rho A/ROCK1 signaling transduces mechanical signals into cellular responses and disrupts regular VIC homeostasis stay unclear. We examined Rho A/ROCK1 signaling in human aortic valves, and further detected how Rho A/ROCK1 signaling regulates mineralization in human VICs.Water-18O MedChemExpress Aortic valves (CAVD n = 22, typical manage (NC) n = 12) from sufferers undergoing valve replacement had been investigated. Immunostaining and western blotting analysis indicated that Rho A/ROCK1 signaling, as well as key transporters and enzymes involved in the Warburg impact, had been markedly upregulated in human calcified aortic valves compared with those inside the controls.PMID:25046520 In vitro, Rho A/ROCK1-induced calcification was confirmed as AMPK-dependent, through a mechanism involving metabolic reprogramming of human VICs to Warburg impact. Y-27632, a selective ROCK1 inhibitor, suppressed the Warburg effect, rescued AMPK activity and subsequently increased RUNX2 ubiquitin-proteasome degradation, leading to decreased RUNX2 protein accumulation in human VICs beneath pathological osteogenic stimulus. Rho A/ROCK1 signaling, that is elevated in human calcified aortic valves, plays a positive role in valvular calcification, partially through its capacity to drive metabolic switching of VICs towards the Warburg effect, leading to altered AMPK activity and RUNX2 protein accumulation. Therefore, Rho A/ROCK1 signaling may very well be an essential and unrecognized hub of destructive hemodynamics and cellular aerobic glycolysis that is definitely crucial to promote the CAVD procedure.
