[Binding of 2-acetylaminofluorene-9-14C with rat liver nucleic acids during malignization and in primary hepatomas]. 1977

S D Ivanov, and F K Dzhioev

The residual binding of 9-14C-2-Acetylaminofluorene (9-14C-2-AAF) with rat liver nuclei acids was investigated during hepatocarcinogenesis two weeks after a single injection of 9-14C-2-AAF. Up to 6 months feeding of the animals with unlabeled 2-AAF, the RNA of their liver proved to bind increased amounts of 9-14C-2-AAF in comparison with normal liver. The binding of 9-14C-2-AAF with DNA in primary hepatomas was mainly due to the RNA heterodispersed components with the maximum level in the 18S-fraction, as well as with the biopolymere fractions with the sedimentation constant of 10 and 5S enriched with polyadenylate fragments.

D006528	Carcinoma, Hepatocellular	A primary malignant neoplasm of epithelial liver cells. It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested.
