Abstract:Endometrial carcinoma (EC) is the most common malignancy of the female genital tract. Type I (endometrioid) EC is associated with elevated estrogen signaling. One of the earliest genetic events in human type I EC is loss of the tumor suppressor gene PTEN. Loss of PTEN allows unrestrained activation of the AKT kinase, which, in turn, regulates such key processes as proliferation, survival, cell size, and mRNA translation. We have previously shown, using a Pten+/− mouse model, that the neoplastic lesions develop… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
