Bile acid sulfation was studied in primary hepatocyte cultures. The primary hepatocyte cultures formed glycolithocholate-3-sulfate (GLC-S) when glycolithocholate (GLC) was added to the medium. The relative percentage of GLC-S formation increased when the GLC concentration was increased from 10 microM to 100 microM. GLC-S formation was linear to 60 min. GLC-S secretion into the medium was detectable at 75 min and linear to 8 hr. In contrast to the effect of GLC concentration, there was no difference in GLC-S formation or secretion when inorganic sulfate in the medium was increased 16-fold (100 microM-1600 microM). We conclude that the rate of bile acid sulfate formation in cultured primary hepatocytes is primarily controlled by bile acid, but not inorganic sulfate, concentration.
