Abstract:
HT-29 sublines and Caco-2 clones were analyzed for the expression of cytochrome P-450 3A. The enzyme was found to be expressed in differentiated HT-29 cells selected by resistance to methotrexate and in one of seven Caco-2 clones, TC7. Its expression parallels the differentiation process, with highest levels being observed at late confluency. P-450 3A mRNA and protein patterns, as well as subcellular distribution, are intermediate between those observed in human adult intestine and fetal liver.
