MTA1 expression in epithelial ovarian neoplasm / 대한산부인과학회지

ABSTRACT

OBJECTIVE: MTA1 has been identified as a metastasis-promiting gene, and its gene expression is correlated with invasion and metastasis in several cancers. We examined MTA1 expression levels in epithelial ovarian neoplasm. METHODS: Expression of MTA1 was evaluated by immunohistochemistry and tissue array in 53 benign tumors, 27 borderline tumors and 68 malignant tumors. The data was analyzed in reference to various clinicopathological parameters. RESULTS: Increased expression of MTA1 was significantly correlated with histologic grade and FIGO stage. There was no relationship between MTA1 expression and age, histologic type, tumor size. CONCLUSION: These results suggest that MTA1 is closely related to invasiveness and progression in epithelial ovarian neoplasm. The MTA1 could thus potentially provide information on the mechanism of cancer invasion and metastasis.
