Hormonal Control of DNA Synthesis and Its Possible Significance to the Problem of Liver Regeneration
Tiae initiation of DNA synthesis has been studied in quiescent primary cultures of fetal rat hepatocytes using defined hormones and chemically defined medium. Preparations of crystalline insulin (0.01-10 ~tg/ml) or 20,000-fold purified somatomedin (0.01-1 ag/ml) are stimulatory. Growth hormone (0.025 ~tg/ml) and hydroxycortisone (0.025 #g/ml), 3 ' :5 ' -GMP! (10 -5 M) fail by themselves to init...
متن کاملHormonal control of pyruvate dehydrogenase activity in rat liver.
A detailed study of the control of liver pyruvate dehydrogenase activity by various hormones was carried out with perfused liver and isolated hepatocytes. Vasopressin produced a significant increase in the enzyme activity in fed rats, and the time course and sensitivity of the response was similar to that of glycogen phosphorylase a. The enzyme from starved animals was resistant to hormonal act...

متن کاملHormonal and enzymatic parameters of hepatic regeneration in patients undergoing major liver resections.
Thirteen patients who underwent 40% to 80% removal of their livers had blood samples drawn initially and daily on postoperative days 1 to 7. The enzyme marker of heightened polyamine metabolism, ornithine decarboxylase, and the indicator of DNA synthesis, thymidine kinase, were measured. In addition, the hormones (insulin, glucagon, estradiol and androgen), which in animals are known to reflect...
متن کاملHormonal control of glycogenolysis in parenchymal liver cells by Kupffer and endothelial liver cells.
Conditioned media of isolated Kupffer and endothelial liver cells were added to incubations of parenchymal liver cells, in order to test whether secretory products of Kupffer and endothelial liver cells could influence parenchymal liver cell metabolism. With Kupffer cell medium an average stimulation of glucose production by parenchymal liver cells of 140% was obtained, while endothelial liver ...
