Increased amounts of tubular immunoreactive renin were noted in polycystic kidneys, as compared to normal kidneys and kidneys with renal artery stenosis.
In atheromatous renal artery stenosis (RAS), a condition characterized by persistent activation of the renin-angiotensin system, the study of these genes may be of particular relevance.
We evaluated angiotensin-converting enzyme (ACE) insertion/deletion, angiotensinogen (AGT) M235T, and angiotensin II receptor (ATR) A1166C polymorphisms in relation to the occurrence of RAS.
We investigated plasma folate and vitamin B12, methylenetetrahydrofolate reductase (MTHFR) C677T and cystathionine beta-synthase (CBS) 844ins68 polymorphisms, and homocysteine levels before and after methionine (100 mg/kg) loading in 58 patients with angiographically documented renal artery stenosis and mildly impaired renal function.
