Homocysteine regulates endothelin type B receptors in vascular smooth muscle cells
Vascular smooth muscle endothelin type B (ETB) receptor is involved in the pathogenesis of cardiovascular diseases (CVDs). Hyperhomocysteinemia is an independent risk factor for CVDs. The present study was designed to examine the hypothesis that homocysteine (Hcy) up-regulates vascular smooth muscle ETB receptors. In vitro experiments were performed in rat superior mesenteric artery (SMA) and vasc
