ABSTRACT
Avian lipogenesis was studied in the chicken hepatocarcinoma LMH cell line. The differentiated and lipogenic status of these cells was evidenced by the presence of the albumin mRNA as well as of some mRNA coding for enzymes involved in lipogenesis (acetyl-CoA carboxylase, fatty acid synthase, delta 9 desaturase) and for apoproteins (apoprotein B and A1). These results were further confirmed by the analysis of triglyceride synthesis and secretion rates in growing cells. A time course analysis showed that triglyceride metabolism was affected by cell density. Hormone responsiveness of triglyceride production was also analyzed. Insulin, triiodothyronine and glucagon to a lesser extent were shown to regulate lipogenesis of LMH cells. The results were compared with those obtained in primary cultures of chicken hepatocytes.
