Active RhoA Exerts an Inhibitory Effect on the Homeostasis and Angiogenic Capacity of Human Endothelial Cells.

ABSTRACT: Background The small GTPase RhoA (Ras homolog gene family, member A) regulates a variety of cellular processes, including cell motility, proliferation, survival, and permeability. In addition, there are reports indicating that RhoA-ROCK (rho associated coiled-coil containing protein kinase) activation is essential for VEGF (vascular endothelial growth factor)-mediated angiogenesis, whereas other work suggests VEGF-antagonistic effects of the RhoA-ROCK axis. Methods and Results To elucidate this issue, we examined human umbilical vein endothelial cells and human coronary artery endothelial cells after stable overexpression (lentiviral transduction) of constitutively active (G14V/Q63L), dominant-negative (T19N), or wild-type RhoA using a series of in vitro angiogenesis assays (proliferation,
