Expression of Cyr61 in ApoE−/− mice with chronic unilateral renal artery ligation

Abstract Cyr61 is a member of the CCN family of proteins that is expressed in atherosclerotic lesions and regulated by angiotensin II. It is unknown whether renal artery stenosis (RAS) increases Cyr61 expression. Male ApoE−/− mice were randomized to surgically induced RAS, RAS + treatment with eithe...
