title: Expanding targets of vitamin D receptor activation: downregulation of several RAS components in the kidney.
abstract: Vitamin D receptor (VDR) activation has a beneficial influence on the progression of experimental renal insufficiency, and reduced renal tissue renin expression may play a role in this process. Freundlich and co-workers now report that VDR activation also suppresses the expression of angiotensinogen, angiotensin II type 1 receptor, and renin receptor in the kidneys of 5/6 nephrectomized rats, effects associated with reduced blood pressure and urinary protein excretion and with alleviated renal tissue damage.
