Effects of adenosine 5'-monophosphate and adenosine 3',5'-cyclic monophosphate on l cells.
The adenine nucleotides, 5'-AMP and 3',5'-cyclic AMP block L cells in the S-phase of the cell cycle. The intracellular level of cyclic AMP is reduced after incubation of cells with 5'-AMP, and rates of uridine transport are increased after incubation with either 5'-AMP or cyclic AMP. On the contrary, cyclic AMP levels are increased and uridine transport decreased in cells treated with an inhibi...
متن کاملAn effect of insulin on adipose-tissue adenosine 3':5'-cyclic monophosphate phosphodiesterase.
1. 3':5'-Cyclic nucleotide phosphodiesterase activity was measured in homogenates prepared from epididymal fat-pads and isolated fat-cells incubated in the absence and presence of insulin. 2. Homogenates of insulin-treated tissues showed an increase in phosphodiesterase activity compared with controls. No effect of insulin was observed when the hormone was added directly to homogenates. 3. Ther...
متن کاملAdenosine-mediated elevation of cyclic 3':5'-adenosine monophosphate concentrations in cultured mouse neuroblastoma cells.
Adenosine causes an increase in the concentration of cyclic AMP in mouse neuroblastoma cells. The amount of increase observed in intracellular cyclic AMP levels due to exogenous adenosine depends greatly on the concentration of a specific cyclic AMP phosphodiesterase inhibitor, 4-(-3-butoxy-4-methoxybenzyl)-2-imidazolidinone. Unstimulated concentrations of cyclic AMP were 29-40 pmol/mg of prote...
