Tryptophan Uptake

The rate of tryptophan metabolism in isolated liver cells from animals fed on a high-leucine diet was greater than for cells from control animals. Leucine inhibited tryptophan metabolism and tryptophan uptake in isolated liver cells, probably by competing for membrane transport. Leucine had no effect on tryptophan 2,3-dioxygenase in vitro. 4-Methyl-2-oxovalerate increased tryptophan oxidation in incubations containing albumin, by displacing bound tryptophan and increasing the availability of the amino acid to the cell. The results suggest that, under extreme conditions, when the availability of tryptophan is low, leucine may be pellagragenic.

Isolated Liver

Preparations of isolated liver cells, either freshly prepared or in culture, have been available for many years; however, because they lack the polarization of the cell in the tissue, their application to the study of processes involved in bile formation has been very limited. The hepatocyte couplet model offers a unique opportunity to study in vitro the intracellular processes involved: not only the physiology and pathophysiology of bile formation, but also the corresponding structural and molecular disturbances underlying different experimental models of cholestasis. In this review we describe the experimental data generated from this model in our laboratory over a period of years, including application of hepatocyte couplets to the study of cytoskeletal changes within the hepatocyte and mechanisms of hepatoprotection in experimentally induced, clinically relevant models of intrahepatic cholestasis.
