Effects of Losartan on the regulation of the expression of myocardial AT_(1a)mRNA,AT_(1b) mRNA from renovascular hypertensive rats / 中国药理学通报

ABSTRACT

0 05).③The level of the expression of AT 1a mRNA of the NO group rats was decreased significantly after hypertension of appeared and that of AT 1b mRNA of the LO group rats increased markedly after Losartan was administered. CONCLUSION Losartan has antihypertensive effects and can reverse myocardial hypertrophy induced by renovascular hypertension. Losartan regulates the mRNAs of the AT 1 receptor subtypes differently, which suggests it possibly has selectivity for AT 1a or AT 1b .
