Cholesterol primes vascular smooth muscle to induce Ca2 sensitization mediated by a sphingosylphosphorylcholine-Rho-kinase pathway: possible role for membrane raft


, : Cholesterol primes vascular smooth muscle to induce Ca2 sensitization mediated by a sphingosylphosphorylcholine-Rho-kinase pathway: possible role for membrane raft. Circulation Research 99(3): 299-306

Hypercholesterolemia is a major risk factor involved in abnormal cardiovascular events. Rho-kinase-mediated Ca2+ sensitization of vascular smooth muscle (VSM) plays a critical role in vasospasm and hypertension. We recently identified sphingosylphosphorylcholine (SPC) and Src family tyrosine kinase (Src-TK) as upstream mediators for the Rho-kinase-mediated Ca2+ sensitization.
