中文摘要:
      摘 要: [目的] 研究丝氨酸蛋白酶抑制剂(MASPIN)、乙酰肝素酶(HPA)在卵巢癌的表达和血管生成的作用。[方法] 采用免疫组化法对31例正常卵巢组织、35例上皮性卵巢癌标本进行MASPIN、HPA表达检测,CD34抗体标记血管内皮细胞计数微血管密度(MVD)。MASPIN真核表达质粒体外转染卵巢癌SKOV3细胞,用细胞免疫化学及半定量逆转录聚合酶链反应(RT-PCR)方法检测转染后卵巢癌细胞中HPA蛋白和 HPA mRNA表达变化。[结果] MASPIN在正常卵巢生发上皮细胞和卵巢癌细胞的阳性表达率分别为16.1%(5/31)和57.1%(20/35)(P<0.05)。HPA蛋白在正常卵巢生发上皮细胞未见表达,在卵巢癌细胞的阳性表达率为85.7%(30/35)(P<0.05);MVD在卵巢癌中增高(P<0.05)。MASPIN蛋白表达与卵巢癌病理类型、临床分期和腹水相关(P<0.05)。HPA蛋白表达与卵巢癌淋巴结转移和腹水相关(P<0.05)。细胞免疫组化及RT-PCR方法均证实转染MASPIN cDNA的SKOV3细胞中HPA表达在各组间差异无统计学意义(P>0.05)。 [结论] MASPIN在卵巢癌的发展过程中可能发挥着肿瘤抑制作用,并具有抑制血管生成作用。HPA表达与卵巢癌的恶性生物学行为密切相关。
英文摘要:
      Abstract: [Purpose] To investigate the expression of mammary serpin(MASPIN)、heparanase(HPA) in ovarian cancer and the role in angiogenesis. [Methods] The expression of MASPIN and HPA was detected immunohistochemically in specimens of normal ovary(n=31) and epithelial ovarian cancer(n=35).Microvessel density(MVD) was counted by endothelial cells immunostained with anti-CD34 monoclonal antibody. The recombinant plasmid pcDNA3-MASPIN was stable transfected into ovarian cancer cell line SKOV3. The expressions of HPA protein and HPA mRNA were determined by immunocytochemistry and RT-PCR. [Results] The positive expression rate of MASPIN was 57.1% in ovarian cancer and 16.1% in normal tissues(P<0.05). The positive expression rate of HPA was 85.7%(30/35) in ovarian cancer and negative expression in normal tissuess(P<0.05). MVD increased in ovarian cancer as compare with control group(P<0.05). MASPIN expression was correlated to pathological type,stage and astites(P<0.05). HPA expression was correlated to lymph node involvement and ascites(P<0.05). The expression of HPA in SKOV3-MASPIN cell after transfected by recombinant plasmid pcDNA3-MASPIN was not significantly different among all the groups both by immunocytochemistry and RT-PCR.[Conclusions] MASPIN might play a role in inhibiting tumor and angiogenesis in ovarian cancer. HPA expression correlates to malignant biological behaviors in ovarian cancer.
