Abstract
The aim of this work was to investigate the coupling of human urotensin II (hU-II) to RhoA activation and regulation of RhoA-dependent functions. The use of the Rho-kinase inhibitor Y-27632 and the development of a membrane-p ermeant RhoA inhibitor (TAT-C3) allowed us to demonstrate that hU-II induce d arterial smooth muscle contraction, actin stress fiber formation, and pro liferation through the activation of the small GTPase RhoA and its downstre am effector Rho-kinase.
