Lack of coordination between glucose-6-phosphatase and gamma glutamyltranspeptidase activities in rat hepatocytes maintained in primary culture.
Glucose-6-phosphatase activity decreases whereas gamma glutamyltranspeptidase activity increases during hepatocarcinogenesis and the maintenance of hepatocytes in primary culture. This report describes the effect of culture conditions that are known to preserve hepatic glucose-6-phosphatase activity on gamma glutamyltranspeptidase activity. The results indicate that the regulation of glucose-6-phosphatase and gamma glutamyltranspeptidase activities is not coordinated in primary cultures of hepatocytes.
