Cloning of cDNA coding for carbamyl phosphate synthetase I and changes in levels of CPS1 mRNA during hepatocarcinogenesis

Abstract
cDNA coding for carbamyl phosphate synthetase I was cloned from recombinant plasmid with insert complementary to the mRNA for CPS1 followed by hybrid-selected translation screening. The length of the insert CPS1 cDNA was approximately 800 base pairs. Using this cDNA as a probe, it was found by dot-blot analysis of the total RNAs and poly(A)+-RNAs isolated from rat livers with different pathological lesions induced by diethylnitrosamine that the levels of CPS1 mRNA were decreased, the decrease being correlated with the malignancy of hepatocytes during carcinogenesis.
