APC10.1 cells as a model for assessing the efficacy of potential chemopreventive agents in the Apc(Min) mouse model in vivo

Apc(Min) mice are widely used for mechanism and efficacy studies associated with the development of chemopreventive agents. APC10.1 cells have been derived from Apc(Min) mouse adenomas and retain the heterozygous Apc genotype. We tested the hypothesis that this cell type may provide an in vitro mode...

Description
Summary:Apc(Min) mice are widely used for mechanism and efficacy studies associated with the development of chemopreventive agents. APC10.1 cells have been derived from Apc(Min) mouse adenomas and retain the heterozygous Apc genotype. We tested the hypothesis that this cell type may provide an in vitro model to predict chemopreventive activity of agents in the Apc(Min) mouse in vivo. The growth inhibitory properties of 14 putative colorectal cancer chemopreventive agents, tricin, apigenin, 3',4',5',5,7-pentamethoxyflavone, resveratrol, curcumin, 3,4-methylenedioxy-3',4',5'-trimethoxychalcone (DMU135), 3,4,5,4'-tetramethoxystilbene (DMU212), celecoxib, aspirin, piroxicam, all-trans-retinoic acid, difluoromethylornithine (DFMO), quercetin and cyanidin-3-glucoside, were studied in this cell line, and the IC(50) values were calculated. The IC(50) values were plotted against previously published data of reduction of adenoma numbers caused by these agents in Apc(Min) mice. The correlation co-efficient was 0.678 (p
