RRM2在上皮性卵巢肿瘤组织中的表达及其与血管生成的关系

目的探讨核糖核苷酸还原酶小亚基(RRM2)在上皮性卵巢肿瘤中的表达及其与血管生成的关系。方法采用免疫组织化学PV-6000二步法和RT-PCR法,检测RRM2、CD105(Endoglin)在正常卵巢、良性卵巢肿瘤、低度潜在恶性上皮性卵巢肿瘤和上皮性卵巢癌组织中的表达,用CD105(Endoglin)标记微血管密度(MVD),并分析RRM2 mRNA和CD105 mRNA表达的关系。结果 (1)低度潜在恶性上皮性卵巢肿瘤组织(1.586±0.650,66.67%)和上皮性卵巢癌组织(1.870±0.618,69.35%)的RRM2 mRNA表达量和蛋白阳性表达率均高于正常卵巢组织(0.771±...

Summary:目的探讨核糖核苷酸还原酶小亚基(RRM2)在上皮性卵巢肿瘤中的表达及其与血管生成的关系。方法采用免疫组织化学PV-6000二步法和RT-PCR法,检测RRM2、CD105(Endoglin)在正常卵巢、良性卵巢肿瘤、低度潜在恶性上皮性卵巢肿瘤和上皮性卵巢癌组织中的表达,用CD105(Endoglin)标记微血管密度(MVD),并分析RRM2 mRNA和CD105 mRNA表达的关系。结果 (1)低度潜在恶性上皮性卵巢肿瘤组织(1.586±0.650,66.67%)和上皮性卵巢癌组织(1.870±0.618,69.35%)的RRM2 mRNA表达量和蛋白阳性表达率均高于正常卵巢组织(0.771±0.495,0)和良性卵巢肿瘤组织(0.952±0.601,26.67%)(P〈0.05)。(2)低度潜在恶性上皮性卵巢肿瘤组织(2.190±0.512,23.15±4.38)和上皮性卵巢癌组织(2.735±0.636,25.27±6.91)中的CD105 mRNA表达量和MVD均高于正常卵巢组织(0.686±0.637,3.40±1.78)和良性卵巢肿瘤组织(0.763±0.547,12.15±2.29)(P〈0.05)。(3)RRM2 mRNA表达量和蛋白阳性表达率在低度潜在恶性组和FIGOⅠ~Ⅱ期卵巢癌组高于正常卵巢组和良性卵巢肿瘤组(P〈0.05),在FIGOⅢ~Ⅳ期高于Ⅰ~Ⅱ期(t=-2.370,χ2=5.937,P〈0.05)。(4)RRM2 mRNA和CD105mRNA之间表达呈正相关(r=0.713,P〈0.05)。结论 RRM2可能参与上皮性卵巢癌发生的早期事件,对上皮性卵巢癌的血管生成可能有一定促进作用,有望成为一个新的早期诊断指标。

Methods The mRNA and protein level o{ RRM2 and CDI(15 in 98 ovarian specimens(in- cluding 15 normal, 15 benign , 6 borderline and 62 malignant) were detected by RT-PCR and irnmunohis tochemistry. The relationship between the expressions of two genes was analyzed. Results ( 1 ) The mR- NA level and protein positive rates of RR1VL2 in borderline ovarian neoplasms(1. 586± 0.650, 66. 67 %) and ovarian cancers (l. 870± 1). 61, 69. 35%)were both higher than those in normal group (0. 771 ± 1). 495,0) and benign group(0. 952 ± 0.61)1, 26. 67%) (P〈0.05). (2)The mRNA level and MVD of CD 105 in borderline ovarian neoplasms(2. 190± 0. 512, 23. 15 ±4. 38) and ovarian cancers(2. 735 ± 0. 636, 25.27± 6. 91) were both higher than those in normal group(0. 686± 0. 637,3.40± 1.78) and benign group(0. 763 ± 0. 547, 12.15 ± 2.29) (P〈0.05).
