title: [Effects of dibutyryl derivatives of cyclic nucleotides on synthesis of total RNA and proteins in cultured fetal rat hepatocytes].
abstract: During short-term (6 h) or long-term (24 h) incubation of fetal rat liver cells in primary cultures, 10(-3) M dibutyryl-derivative of cyclic AMP (Bt2cAMP) and sodium butyrate decreased total RNA and protein synthesis. In contrast, dibutyryl-cyclic GMP (Bt2cGMP) at the same dose (10(-3) M) was without significant effect on RNA and protein biosynthesis. During short-term (4 h) incubation 10(-3) M Bt2cAMP and Bt2cGMP stimulated serum albumin production, while sodium butyrate was without effect. In long-term (22 h) incubation only 10(-3) M Bt2cAMP noticeably increased albumin production. The results obtained clearly show that Bt2cGMP, unlike Bt2cAMP, is not able to modify significantly total RNA and protein synthesis in cultured fetal rat liver cells. It is concluded also that the effects of dibutyryl-derivatives of cyclic nucleotides, at least on albumin production, are not mimiebet by butyrate.
