Abstract :

Human epithelial ovarian cancer (EOC) is the most lethal gynaecological malignancy in women. It is highly lethal because of being an advanced stage upon diagnosis. Despite the improvement of treatment during last two decades, overall survival of patient with ovarian cancer at the advanced stage has not been enhanced significantly. Therefore gaining biomarkers of early detection at an early curable stage and understanding how the EOC develops, are most important. Using proteomics, tissue microarray, immunohistochemistry and ELISA, several potential epithelial-type ovarian tumor progression markers were identified. The association of these tumor progression markers with clinicopathological features was further analyzed. We found that several proteins were differentially expressed between normal ovarian tissue and ovarian surface epithelial benign, borderline and malignant tumors, including serous, mucinous and clear cell tumors. Using loss-of-function approach, we found that these molecules were involved in EOC cell proliferation, migration and invation. We also demonstrated that these molecules were regulated by the TGF-�² signaling pathway. Furthermore, some of these biomarkers affected tumor formation in nude mice. Thus, the identification of tumor markers as novel EOC-related proteins may implicate for understanding tumorigenesis and provide a diagnostic tool and better therapeutic strategy.
