ABSTRACT
Backgroud and Objective Proline-rich tyrosine kinase2(Pyk2) is a Ca~(2+) sensitive,non-receptor tyrosine protein kinase.Previous reports showed Pyk2 involved in development of left ventrieular hypertrophy. The present paper aimed to study the effects of valsartan on ventricular hypertrophy and its effect on the expression of Pyk2 in myocardium in renovascular hypertensive rats(RHR).Methods Two-kidney and one-clip(2K1C) renal hypertensive model was established in Sprague-Dawley rats by chronic partial occlusion of left renal artery,and ran- domized to receive valsartan (30 mg/kg?d) or without treatment for 4 or 8 weeks.Left ventricular mass to body mass ratio was measured.Pyk2 protein expression and phosphorylation was detected by Western blotting.Results Blood pressure,left ventricular mass to body mass ratio,Pyk2 activity in myocardium of RHR were increased gradu- ally.Valsartan reduced BP and prevent myocardial hypertrophy(P
