Table 1 Sources of total RNA samples

Number and type of samples	Animal treatment
HCC tissue
1 Tree shrew in AFB1 group died of HCC at the 88th week of treatment with an amount of AFB1 up to 10.4 mg.
2 Tree shrew in AFB1 group died of HCC at the 89th week of treatment with an amount of AFB1 up to 11.3 mg.
HCC-surrounding non-cancerous liver tissue
3 Autopsy tissue from the same animal and at the same time as #1
4 Autopsy tissue from the same animal and at the same time as #2.
Liver tissue taken before HCC developed
5 Biopsy tissue from the same animal as #1, at the 30th week of AFB1-treatment with a total amount of 3.1 mg AFB1.
6 Biopsy tissue from the same animal as #2, at the 30th week of AFB1-treatment with a total amount of 3.2 mg AFB1.
Liver tissue taken before AFB1-treatment
7 Biopsy tissue mixture from 3 animals before they were grouped and treated (0th week of the experiment).
Homochronous control
8 Biopsy tissue mixture from 2 animals in control group at the 90th week of the experiment.
