Abstract
The influence of 4-aminopyrazolopyrimidine (4-APP) on morphology and on synthesis and secretion ability of isolated rat hepatocytes was investigated: 4-APP was found to inhibit both the synthesis and secretion of proteins. The synthesis of triglycerides was unaffected by 4-APP, while the secretion of triglycerides was markedly reduced. Transmission electron microscopy revealed that 4-APP induced morphological changes in the smooth membrane systems, the smooth endoplasmic reticulum and the Golgi apparatus. The possibility that 4-APP inhibits lipoprotein formation by inhibition of the apoprotein synthesis is discussed.
