Indeed, oxidative stress-induced drop of bile flow and/or decrease of the bile salt-secretory rate becomes aparent before leakage of cytosolic hepatocellular enzymes or increments in intracellular GSSG levels is induced by administration of different pro-oxidant compounds to isolated perfused rat livers.70,75 Likewise, in isolated rat hepatocyte couplets, an in vitro model for the study of hepatocanalicular function, the secretion of fluorescent bile-salt analogues into the canalicular vacuole was impaired by low concentrations of the pro-oxidant compounds, tBOOH and 2,3-dimethoxy-1,4-naphthoquinone, even when GSSG intracellular levels and cellular viability were unaffected.98 Finally, also in the couplet model, a dissociation between apical secretion of fluorescent bile-salt analogues and the amount of GSSG produced in the cell by the oxidizing effects of redox-cycling quinones has been reported.99 Overall, these results suggest that more subtle changes in the machinery involved in bile formation occur under mild oxidative stress conditions
