title: Influence of cyclic AMP on DNA synthesis in slices of regenerating rat liver.
abstract: DNA synthesis in slices of regenerating rat liver is inhibited by adenosine cyclic 3',5'-monophosphate [cAMP]. The number of cells synthesizing DNA as assayed by 2-14C-thymidine incorporation is reduced by 65% in the presence of 10(-3) M cAMP. The inhibition of cAMP is not specific; other adenosine compounds, N6,O2,-dibutyryl adenosine 3',5'-monophosphate, 5'AMP and adenosine have the same effect. Moreover, the concentration of cAMP in the cell required for this inhibition is much higher than the normal levels of cAMP in liver cells.
