Unique Properties of Hepatocarcinogenesis-Resistant DRH Rat Hepatocytes Linked or Not Linked to the Drh1 Locus on Rat Chromosome 1

Figure 2

Proliferation of hepatocytes in Donryu, DRH, DRH.F344-Drh1, and F344 rats after LN treatment. (a) Day 2 after LN treatment. BrdU(+) hepatocyte nuclei occurred frequently in Donryu, DRH.F344-Drh1, and F344 livers but occurred much less frequently in DRH livers. (b) The BrdU LI in hepatocytes was most strongly increased on day 2 after LN treatment in Donryu, DRH.F344-Drh1, and F344 livers but was much lower in DRH livers. * in comparison with DRH ( ) against Donryu ( ), DRH.F344-Drh1 ( ), or F344 ( ).
