Abstract
The human colon carcinoma cell line Caco-2 was examined for glutathione S-transferase (GST) composition and activity. Freshly seeded cells and cells until 4 days after confluency contain only the placental (Pi) form of glutathione transferase. Cells in culture for longer periods start to express class-Alpha GST isoenzymes. Confluent cells in culture for 20 days or longer contain up to 90% class-Alpha GST. Class-Mu GSTs are not detectable. GST activity gradually increases from 564 +/- 28 to 5381 +/- 165 nmol/min per mg of protein at day 0 and 32 after confluency respectively. With regard to GST composition, Caco-2 cells in culture for longer periods most resemble small-intestinal cells, whereas short-time cultures have characteristics of colonic cells. This cell line is very well suited for the study of both the in vitro properties and the expression of class Alpha and Pi GSTs.
