Increased vascular heme oxygenase‐1 expression contributes to arterial vasodilation in experimental cirrhosis in rats
Yung‐Chang Chen, Pere Ginès, Jianhui Yang, Sandra N. Summer, Sandor Falk, Nash S. Russell, Robert W. Schrier – 25 March 2004 – Vascular heme oxygenase (HO) regulates vascular tone in normal conditions and in some pathologic circumstances (e.g., sepsis). However, its possible role in the pathogenesis of arterial vasodilation in cirrhosis is unknown. To address this question, the expression and activity of HO in arterial vessels was studied in rats at 1, 2, and 4 weeks after bile duct ligation (BDL) or sham operation.
