The objective of this study was to characterize rainbow trout (Oncorhynchus mykiss) gill epithelial cells in primary culture by evaluating their ability to maintain glutathione and glucuronide conjugating enzymes. The activity and inducibility of the phase II enzymes was investigated as a function of culture time. Glutathione S-transferase (GST) and UDP-glucuronyltransferase (UDPGT) enzyme activities were measured in freshly isolated cells and in cells cultured for 7 and 12 days. GST activity, determined with 1-chloro-2,4-dinitrobenzene, decreased gradually to 72% after 7 days and to 38% after 12 days in culture compared with freshly isolated cells. There was no significant difference between UDPGT activities in freshly isolated cells compared with cells cultured up to 12 days although a transient decrease in activity was observed at day 7. In vitro induction of the enzymes was studied using beta-naphtoflavone (BNF) and 3-methylcholanthrene (3-MC) as inducers. GST activity increased 2-fold after exposure to BNF and 1.5-fold after 3-MC exposure for 48 h in 7 days old cultures. No induction was observed in 12 days old cultures. UDPGT activity was not induced either at day 7 or 12.
