Abstract excerpt
CTNNB1 exon 3 mutation is a well-established driver of nearly 30% of endometrioid endometrial cancers (EECs), and this is associated with worse patient survival. Paradoxically, we have previously demonstrated that mutant β-catenin protein does not robustly localize to the nucleus in these cancers. The purpose of this study was to determine downstream gene expression in these cancers with nuclear or...
