Cholesterogenesis and related enzymes in isolated rat hepatocytes during pre- and postnatal life
Cholesterogenesis pathway during pre‐ and postnatal development was studied in isolated rat hepatocytes. No modified activity of cytosol acetoacetyl coenzyme A (CoA), thiolase, or 3‐hydroxy‐3‐methylglutaryl CoA (HMGCoA) synthase was detectable at the different stages examined. Minimal levels of 114C...

Zusammenfassung: | Cholesterogenesis pathway during pre‐ and postnatal development was studied in isolated rat hepatocytes. No modified activity of cytosol acetoacetyl coenzyme A (CoA), thiolase, or 3‐hydroxy‐3‐methylglutaryl CoA (HMGCoA) synthase was detectable at the different stages examined. Minimal levels of 114C‐acetate incorporation into cholesterol and HMGCoA reductase activity were present at 16 days of fetal development in newborn and suckling rats, whereas both parameters increased rapidly before birth. The pattern of NaF nonsuppressible reductase activity showed a different activation state of the enzyme, suggesting the appearance of a modulation state, probably related to the development of some short‐term regulatory mechanisms. |
