abstractText | Endometrioid adenocarcinoma is the most frequent form of endometrial cancer, usually developing in pre- and peri-menopausal women. beta-catenin abnormalities are common in endometrioid type endometrial carcinomas with squamous differentiation. To investigate the role of beta-catenin (Ctnnb1) in uterine development and tumorigenesis, mice were generated which expressed a dominant stabilized beta-catenin or had beta-catenin conditionally ablated in the uterus by crossing the PR(Cre) mouse with the Ctnnb1(f(ex3)/+) mouse or Ctnnb1(f/f) mouse, respectively. Both of the beta-catenin mutant mice have fertility defects and the ability of the uterus to undergo a hormonally induced decidual reaction was lost. Expression of the dominant stabilized beta-catenin, PR(cre/+)Ctnnb1(f(ex3)/+), resulted in endometrial glandular hyperplasia, whereas ablation of beta-catenin, PR(cre/+)Ctnnb1(f/f), induced squamous cell metaplasia in the murine uterus. Therefore, we have demonstrated that correct regulation of beta-catenin is important for uterine function as well as in the regulation of endometrial epithelial differentiation. |
