| Research Abstract |
(1)We have demonstrated that Rho/Rho-kinase-mediated pathway plays an important role in the pathogenesis of hypertension.
(2)We have demonstrated that Rho-kinase-mediated pathway is substantially involved in the pathogenesis of angiotensin II-induced cardiovascular hypertrophy in rats.
(3)We have demonstrated that Rho-kinase is located downstream of PKC in the signal transduction of vascular smooth muscle for coronary spasm in a porcine model.
(4)We have demonstrated that long-term treatment with a Rho-kinase inhibitor suppresses the development of in-stent restenosis in porcine coronary arteries.
(5)We have demonstrated that long-term treatment with a Rho-kinase inhibitor suppresses the development of LV remodeling after myocardial infarction in mice through inhibition of the expression of inflammatory cytokines.
(6)We have demonstrated that long-term treatment with a Rho-kinase inhibitor suppresses the development of monocrotaline-induced pulmonary hypertension in rats.
(7)We have demonstrated that Rho-kinase is substantially mediated in the pathogenesis of microvascular angina.
