Abstract excerpt
Ectopic expression of certain Wnt genes in mouse mammary tissue is tumorigenic, and mutations that stabilize beta-catenin are found in various human cancers including colorectal cancer. To determine the role of stabilized beta-catenin in intestinal tumorigenesis in mice, we constructed by embryonic stem (ES) cell-mediated homologous recombination, a mutant beta-catenin allele whose exon 3 was sandwiched by loxP...
