DNA synthesis and interaction between controlled feeding schedules and partial hepatectomy in rats.

The rate of DNA synthesis has been measured during liver regeneration in rats adapted to a controlled feeding schedule. The results show two different phenomena in the regulation of DNA synthesis. The first is the appearance of a peak of DNA synthesis following the operation itself and independent of the time of the day; the second one is the presence of constant diurnal variations in the rate of DNA synthesis in response to the partial hepatectomy and following the stimulus or stimuli of the controlled feeding schedule.

Amino acid transport in hepatoma cell cultures during tyrosine aminotransferase induction.

Alpha-aminoisobutyric acid transport in hepatoma cells in culture was increased by insulin but not by hydrocortisone. Both of these agents induce tyrosine aminotransferase activity in this system. The apparent increase in alpha-aminoisobutyric acid transport and tyrosine aminotransferase activity produced by glucagon is probably caused by insulin contamination. Insulin did not increase transport in this system until after tyrosine aminotransferase activity had reached maximum levels. The mechanisms underlying increased alpha-aminoisobutyric acid transport appear to differ from those for tyrosine aminotransferase induction with hydrocortisone despite their close association in previous whole animal experiments.
