| Outline of Final Research Achievements |
Our aim is to clarify the similarity of molecular characteristics in both ovarian and uterine endometrial serous carcinoma. We performed protein expression profiling on 14 cases of serous carcinomas (7 ovarian and 7 endometrial) and 18 endometrioid carcinomas (9 ovarian and 9 endometrial) using iTRAQ. Hierarchical clustering showed the similarity of protein expression profiles between ovarian and endometrial serous carcinomas. Using 45 statistically highly expressed proteins in serous carcinomas, protein ontology analysis detected two enriched terms and proteins composing each term: IMP2 and MCM2. Immunohistochemical analyses confirmed the higher expression of IMP2 and MCM2 in ovarian and endometrial serous carcinomas The knockdown of either IMP2 or MCM2 by siRNA interference significantly decreased the proliferation rate of ovarian serous carcinoma cell line. We suggest that increased IMP2 and MCM2 expression may underlie some of the rapid serous carcinoma growth observed clinically.
