Abstract/OtherAbstract:
Hepatocellular carcinomas from rats of different strains, subjected to a variety of carcinogenic treatment regimens in different laboratories (initiation by diethylnitrosamine or dimethylhydrazine, promotion by phenobarbital, 2-acetylaminofluorene, nafenopin, orotic acid or deoxycholic acid, growth stimulation by partial hepatectomy or necrogenic CCl4 treatment), were all found to be predominantly diploid by flow cytometric analysis, in contrast to normal liver tissue in which polyploid nuclei were predominant. A switch from polyploidization to diploid growth would thus seem to be a common property of malignant liver tumours. Benign neoplastic liver nodules were likewise predominantly diploid, with the exception of nodules induced by long-term deoxycholic acid treatment in Fischer rats. In addition to containing a majority of polyploid cells, the latter nodules failed to progress to the carcinoma stage.
