Resistance arteries are able to adapt to physiological and pathophysiological stimuli to maintain adequate perfusion according to the metabolic demand of the tissue. Although vasomotor control allows rapid adaptation of lumen diameter, vascular remodeling constitutes an active process that occurs in response to long-term alterations of hemodynamic parameters. Unfortunately, this initially adaptive process contributes to the pathology of vascular diseases. Recent studies have demonstrated the participation of Rho protein signaling pathways in several cardiovascular pathologies including hypertension, coronary artery spasm, effort angina, atherosclerosis, and restenosis. Functional analyses have further revealed that RhoA-dependent pathways are involved in excessive contraction, migration, and proliferation associated with arterial diseases. The present review focuses on the role of Rho proteins, in particular RhoA, in vascular smooth muscle cells and the involvement of Rho-dependent signaling pathways in resistance artery remodeling, more particularly in relation to hypertension.
