  [摘要] 目的 研究抑癌基因WWOX及PTEN对卵巢浆液性腺癌细胞生长的影响,探讨卵巢癌基因治疗的新靶点。 方法 于2013年10月―2016年10月福州市第一医院方便选取的60例卵巢浆液性腺癌标本作为研究对象,另选取30例正常卵巢组织作为对照。采用免疫组化检测抑癌基因WWOX及PTEN的阳性率表达,RT-PCR法测WWOX及PTEN的mRNA相对表达量。 结果 卵巢浆液性腺癌中抑癌基因WWOX及PTEN的免疫组化阳性率及mRNA相对表达量均显著低于正常卵巢组织组(P http://

  [Abstract] Objective This paper tries to study the effect of WWOX and PTEN on the growth of ovarian serous adenocarcinoma cells and to explore the new target of ovarian cancer gene therapy. Methods From October 2013 to October 2016, 60 cases of ovarian serous sex adenocarcinoma were selected from fuzhou first hospital,30 other normal ovarian tissue were selected as the control.Immunohistochemistry was used to detect the expression of WWOX and PTEN, the mRNA expression of WWOX and PTEN was measured by RT-PCR.Immunohistochemistry was used to detect the expression of WWOX and PTEN, the mRNA expression of WWOX and PTEN was measured by RT-PCR. Results The immunohistochemical positive rate of mRNA and mRNA expression of WWOX and PTEN in ovarian serous adenocarcinoma were significantly lower than those in normal ovarian tissue (P75%计为4分,阳性细胞数50%~75%计为3分,阳性细胞数25%~50%计为2分,阳性细胞数    1.2.4 RT-PCR 采用??硫酸氰酸胍一步法提取组织总RNA;总RNA的鉴定;反转录合成cDNA;PCR反应;采用凝胶分析软件(BIO-LD)进行定量,各组以目的基因与内参照基因GAPDH量的比值表示目的基因相对表达量。
  1.2.5 统计方法 采用SPSS 18.0统计学软件对数据进行统计学处理和分析,计量资料比较采用方差分析,计数资料的比较采用χ2检验,并分别用(x±s)、[n(%)]表示,P参考文献]
