pubmed:abstractText
Y-1 adrenal cells responded to serum step down by a several fold decrease in DNA synthesis. Serum starved cells resumed DNA synthesis upon serum step up. ACTH and cAMP inhibited DNA synthesis both at low and high serum concentrations, a fact previously known. Pituitary, brain and liver crude extracts stimulated DNA synthesis in serum starved cells. Purified pituitary factors preparations contained two activities: one specific for Y-1 cells and another active with both fibroblasts and Y-1 cells. The kinetics of restimulation of DNA synthesis by serum and pituitary factors was studied. DNA synthesis restimulation occurred after a lag of 11 hours. This lag did not vary irrespective of the type of stimulator or its concentration. Cells entered S phase continuously at a rate which increased with increasing concentrations of the stimulator. Cells became refractory to the inhibitory action of ACTH five hours before entering S phase. The implications of these data to the understanding of cell growth control are considered.
