Methods A panel of normal ovarian tissues, primary OC specimens and corresponding LNS was examined for mRNA expression and mutation of MTA1 and nm23H 1 and protin expression of E cad genes by using RT PCR, RT PCR SSCP and immunohistochemistry.

• 方法 应用 RT- PCR、RT- PCR- SSCP和免疫组化技术 ,对正常卵巢、卵巢癌及其配对淋巴结组织进行 MTA1、nm2 3H1m RNA表达和突变及 E- cad蛋白表达的检测。
