It has been reported that several naturally occurring and related synthetic organosulfur compounds exert chemopreventive effects in several target organs in rodent models. The chemopreventive actions of 40 and 80% maximum tolerated doses (MTD) of organosulfur compounds, namely anethole trithione,
The chemopreventive efficacy of N-acetyl-L-cysteine (NAC), anethole trithione, miconazole and phenethylisothiocyanate (PEITC), each of which would be expected to alter carcinogen metabolism, was examined in the dimethylbenzanthracene (DMBA) mammary carcinogenesis model. In this protocol, animals
Large bowel cancer is one of the leading causes of cancer deaths in the United States and other Western countries. Based on epidemiologic and mechanistic studies, preclinical studies were designed to evaluate the chemopreventive efficacy of several nonsteroidal antiinflammatory drugs (NSAIDs) and
Previously, we developed a 30-day transformation assay (focus inhibition, FIA) of rat tracheal epithelial (RTE) cells to identify cancer preventive agents. This study reports nuclear density (ND) as a morphometric biomarker for efficacy evaluation of at an early stage before transformed foci appear.
