The role of RhoA/Rho kinase pathway in endothelial dysfunctionLin Yao, Maritza J. Romero, Haroldo A. Toque, Guang Yang, Ruth B Caldwell, R. William Caldwell.
Endothelial dysfunction is a key event in the development of vascular disease, and it precedes clinically obvious
vascular pathology. Abnormal activation of the RhoA/Rho kinase (ROCK) pathway has been found to elevate
vascular tone through unbalancing the production of vasodilating and vasoconstricting substances. Inhibition
of the RhoA/ROCK pathway can prevent endothelial dysfunction in a variety of pathological conditions. This
review, based on recent molecular, cellular, and animal studies, focuses on the current understanding of the
ROCK pathway and its roles in endothelial dysfunction.
