O článku:
This study was designed to determine particular changes in the renin gene expression and activity in renal cortex and medulla after AT1 receptor blockade. It was found that two-week-treatment with AT1 blocker losartan induced an increase in tissue renin activity in both parts of kidney causing subsequent elevation of plasma renin activity. Renin mRNA in losartan-treated rats was increased only in cortex, suggesting cortex origin of elevated renin activity in medulla. Medullary renin mRNA indicated local synthesis of renin within the whole kidney and supported the idea of the presence of tissue renin-angiotensin system. Our results show that gene expression of renin in kidney medulla is insensitive to AT1 receptor blockade and this points out that the regulation of kidney renin-angiotensin system probably differs from that in cortex.
