中文摘要:
      目的: 探讨干扰素介导的跨膜蛋白 1( Interferon-induced transmembrane protein 1, IFITM1)基因 在卵巢上皮性癌中表达的相 关性及其意义。 方法: 应用 Western blotting 检测正常卵巢、卵巢良性肿瘤、卵巢交界性肿瘤和卵巢上皮性癌组织中 IFITM1 蛋白表 达。 免疫组织化学检测 12 例 正常卵巢、21 例卵巢良性肿瘤、 18 例卵巢交界性肿瘤和 85 例卵巢上皮性癌组织中 IFITM1 的蛋白表 达, 同时分析 IFITM1 表达状况与 临床病理因 素之间 的相关性。 结果: Western blotting 显示卵巢上皮性癌和卵巢交界性肿瘤中 IFITM1 表达水平明显高于正常卵巢组织和卵巢良性肿瘤。免疫组化显示在正常卵巢组织中 IFITM1 阳性表达率为 41.7 %( 5/12), 在卵巢良性肿瘤组织中 71.4 %( 15/21),在卵巢交界性肿瘤组织中为 72.2 %( 1 3/18),在卵巢上皮性癌中为 77.6 %( 66/85), IFITM1 蛋白表达强度在正常卵巢、良性卵巢肿瘤、交界性卵巢肿瘤、上皮性卵巢癌间的比较有统计学意义( P<0.05)。 IFITM1 蛋白表达与 病理类型、肿瘤分化程度、肿瘤 FIGO 分期有关( P<0.05),与 淋巴结转移、腹水无明显相关性。化疗敏感组和耐药组的 IFITM1 表达 强度间差异有统计学意义( P<0.05)。 结论: IFITM1 在正常卵巢、卵巢良性肿瘤、卵巢交界性肿瘤和卵巢上皮性癌组织中的表达依 次升高, 并与 卵巢癌以铂类为 基础的化疗 耐药性产生有相关性,为 进一步研究 IFITM1 在卵巢癌诊治及化疗中的应用 前景提供依 据。
英文摘要:
      Objective:To investigate the role of Interferon-induced transmembrane protein 1 (IFITM1 ) in the carcinogenesis and evaluate its clinical significance in epithelial ovarian carcinoma.Methods:The expression level of IFITM1 was detected by the Western blot analysis in different ovaries, and the immunohistochemical method (SP) was used to determine the expression levels of IFITM1 among 1 2 normal ovarian tissue cases, 21 benign ovarian tumor cases, 1 8 borderline ovarian tumor cases and 85 ovarian carcinoma cases. Then the relationship between the expression level of IFITM1 in ovarian carcinoma and the clinicopathological features was analyzed by statistics.Results:Western blot analysis showed that the expression levels of IFITM1 differed in different ovarian tissues. The immunohistochemical technique showed that the positive rate of IFITM1 expression was 77.6% (66/85) in ovarian carcinoma, higher than that of ovarian (41 .7 %, 5/12), benign ovarian tumor (71.4 %, 15/21) and borderline ovarian tumor (72.2 %, 13/1 8) with a dramatical statistic significance (P<0.05). The expression level ofIFITM1 was correlated with pathology type, tumor grad and FIGO stage in ovrian carcinoma (P<0.05). The expression intensity of IFITM1 protein in ovarian carcinoma was significantly related to its chemotherapy sensitivity.Conclusion:The expression levels ofIFITM1 gradually increased in normal ovarian tissue, benign ovarian tumor, borderline ovarian tumor and ovarian carcinoma. Positive expression level of IFITM1 played a vital role in carcinogenesis and progression of ovarian carcinoma including the drug-resistance to platinum-based chemotherapy. Our research can provide better evidence to the further study of IFITM1 in diagnosis and targeted treatment of ovarian carcinoma.
