Deoxycholylglycine, a conjugated secondary bile acid, reduces vascular tone by attenuating Ca2+ sensitivity via rho kinase pathway

Patients with cirrhosis have reduced systemic vascular resistance and elevated circulating bile acids (BAs). Previously, we showed that secondary conjugated BAs impair vascular tone by reducing vascular smooth muscle cell (VSMC) Ca2+ influx. In this study, we investigated the effect of deoxycholylglycine (DCG), on Ca2+ sensitivity in reducing vascular tone. First, we evaluated the effects of DCG on U46619- and phorbol-myristate-acetate...
