Gene Set: SANSOM_APC_TARGETS_DN

Standard name SANSOM_APC_TARGETS_DN
Systematic name M1432
Brief description Top genes down-regulated at day 5 of Cre-Lox induced APC [GeneID=324] knockout in the intestine.
Full description or abstract Although Apc is well characterized as a tumor-suppressor gene in the intestine, the precise mechanism of this suppression remains to be defined. Using a novel inducible Ahcre transgenic line in conjunction with a loxP-flanked Apc allele we, show that loss of Apc acutely activates Wnt signaling through the nuclear accumulation of beta-catenin. Coincidentally, it perturbs differentiation, migration, proliferation, and apoptosis, such that Apc-deficient cells maintain a crypt progenitor-like phenotype. Critically, for the first time we confirm a series of Wnt target molecules in an in vivo setting and also identify a series of new candidate targets within the same setting.
