title: Structural and metabolic characterization of RNAs from rats with experimental Guerin tumor - I. Nucleotide composition of RNAs from the liver and tumor tissues of rats.
abstract: The characteristics of the ribonucleic acids of Guerin tumor was the subject of this work. The effect of tumor development on the structure of the ribonucleic acids in the liver of tumor bearing rats was studied. Some differences of nucleotide compositions in RNAs isolated from subcellular fractions of liver of control and tumor bearing rats and of cancer tissue were observed. The nucleotide compositions of cancer nuclear RNA is distinctly different from liver RNA. The changes in primary structure of liver RNAs due by development of tumor in rats may be result of metabolic peculiarities of these RNAs.
