Tumors from rats given 1,2-dimethylhydrazine plus chlorophyllin or indole-3-carbinol contain transcriptional changes in beta-catenin that are independent of beta-catenin mutation status.

Abstract excerpt

Tumors induced in the rat by 1,2-dimethylhydrazine (DMH) contain mutations in beta-catenin, but the spectrum of such mutations can be influenced by phytochemicals such as chlorophyllin (CHL) and indole-3-carbinol (I3C). In the present study, we determined the mutation status of beta-catenin in more than 50 DMH-induced colon tumors and small intestine tumors, and compared this with the concomitant expression of...
