Cholesterol synthesis and 3-hydroxy-3-methylglutaryl CoA reductase (HMG-CoA reductase) in the liver of rats at various times (7, 22, 45 and 314 days) after injection with the carcinogen, methylazoxymethanol acetate (MAMA) is reported. Seven days after treatment, an increase in both cholesterol synthesis and HMG-CoA reductase activity was observed. Elevated HMG-CoA reductase activity and reduced dietary feedback was present 22 days after carcinogen. Cholesterol synthesis was normal at this time but dietary cholesterol failed to significantly reduce synthesis. Forty-five days after carcinogen both cholesterol synthesis and HMG-CoA reductase activity had returned to normal. Both parameters were normal 314 days after carcinogen. The enzyme gamma-glutamyl transferase was also elevated at 7, 22 and 314 days. These results indicate that HMG-CoA reductase activity and cholesterol synthesis exhibit different regulatory characteristics during the early stages of hepatocarcinogenesis initiated by MAMA injection.
