title: Inhibition of DNA synthesis of adult rat hepatocytes in primary culture by dibutyrylcytidine 3', 5'-cyclic monophosphate.
abstract: The effect of dibutyrylcytidine 3',5'-cyclic monophosphate (Bt2cCMP) on DNA synthesis of adult rat hepatocytes in primary culture was examined. Bt2cCMP caused dose-dependent inhibition of the DNA syntheses stimulated by various growth factors including human hepatocyte growth factor (hHGF). Dibutyryladenosine 3',5'-cyclic monophosphate (Bt2cAMP) inhibited the DNA synthesis more effectively than Bt2cCMP, but dibutyrylguanosine 3',5'-cyclic monophosphate (Bt2cGMP) and n-butyrate had a slight or null inhibitory effect. When added at the onset of DNA synthesis, Bt2cAMP was much less effective, but Bt2cCMP was still effective. Thus Bt2cCMP is able to inhibit growth factor-stimulated hepatocyte proliferation.
