Differential expression of genes during aflatoxin B(1)-induced hepatocarcinogenesis in tree shrews.

ABSTRACT: AIM:Through exploring the regulation of gene expression during hepatocarcinogenesis induced by aflatoxin B(1) (AFB(1)), to find out the responsible genes for hepatocellular carcinoma (HCC) and to further understand the underlying molecular mechanism. METHODS:Tree shrews (Tupaia belangeri chinensis) were treated with or without AFB(1) for about 90 weeks. Liver biopsies were performed regularly during the animal experiment. Eight shares of total RNA were respectively isolated from 2 HCC tissues, 2 HCC-surrounding non-cancerous liver tissues, 2 biopsied tissues at the early stage (30th week) of the experiment from the same animals as above, 1 mixed sample of three liver tissues biopsied at the beginning (0th week) of the experiment, and another 1 mixed sample of two liver tissues from the unt
