() Real-time PCR assay of the tg5 flox and tg5 recombinant alleles. Genomic DN was extracted from paraffin-embedded liver sections of tg5 flox/flox ;CG-Cre and tg5 flox/flox mice at different ages, as indicated. The DN quantity of the tg5 flox and recombinant alleles (relative to that of tg14 genomic DN) in tg5 flox/flox MEFs are set as 1 and 0, respectively. The quantities in tg5 / MEFs are set as 0 and 1, respectively. 7 days, n=2; 1 month, n=3; 6 months, n=2; 9 months, n=4; 12 months, n=1; 19 months, n=3.

Immunoblot analysis of liver samples obtained from wild type (indicated as control),, tg7 flox/flox ;lb-cre (non-tumor area and tumor area), and tg7 flox/flox ;lb-cre; mice. Liver homogenates were separated into detergent-soluble and detergent-insoluble fractions with 0.5% Triton X-100. Each fraction was subjected to SDS PGE and analysed by immunoblotting with the indicated antibodies. Nqo1; ND(P)H dehydrogenase quinone 1. The results of three independent experiments are shown.
