To provide a picture of the expression pattern of genes acting in the early stages of liver carcinogenesis, we monitored the expression of ctnntb1, a gene often impaired in human hepato-carcinogenesis, which seemed to be specifically involved in liver tumors occurring in GBLE-treated mice [39], as well as a cancer-specific p53 onco-suppressor gene and the c-myb oncogene. The gene discussed is TP53; the disease is cancer.
