Abstract excerpt
FOXA1 is altered in 10 to 40% of prostate cancers, yet its oncogenic mechanisms remain uncharacterized in vivo. We developed knock-in mouse models representing distinct classes of FOXA1 mutations. Histopathological and multiomic analyses of prostate tissues and organoids revealed that Class 1 mutations, in conjunction with p53 inactivation, drive androgen-dependent adenocarcinomas through coactivation of mTORC1/2...
