New insights into phenotypic switching of VSMCs induced by hyperhomocysteinemia: Role of endothelin-1 signaling
2020
Abstract Phenotypic switching of vascular smooth muscle cells (VSMCs) plays a key role in atherosclerosis. Hyperhomocysteinemia (HHcy) is an independent risk factor for atherosclerosis. HHcy induces phenotypic switching of VSMCs, but the mechanism is unclear. Endothelin-1 (ET-1) promotes proliferation and migration of VSMCs by inducing phenotypic switching during atherosclerosis. This review examined recent findings on the relationship between HHcy or the ET-1 system (including ET-1 and its receptors) and phenotypic switching of VSMCs as well as the molecular mechanism of HHcy-regulated ET-1 signaling. In particular, we focused on the potential mechanisms and pharmacological targets of phenotypic switching of VSMCs regulated by HHcy through ET-1 signaling.
