Membrane potential and hepatic uptake: Another rule of the game
Claudio Tiribelli – 1 September 1986 – Since glucagon can hyperpolarize hepatic plasma membrane and stimulate biliary bile acid secretion in vitro, we studied the effect of glucagon on taurocholate uptake and its relationship to plasma membrane potential in isolated rat hepatocytes. [14C]Taurocholate uptake was linear through 1 min and contained a saturable sodium‐dependent and a nonsaturable sodium‐independent component, Km of taurocholate uptake by the sodium‐dependent system was 18.4 μM.
