2、理特征的关系。结果:①宫颈癌、CINII~Ⅲ及CINI组组织中BRMS1蛋白的表达低于慢性宫颈炎组,差异有统计学意义(均P1,2、有淋巴结转移者中表达降低甚至缺失(均P<0.05)。②NF—KBp50蛋白在宫颈癌组、CINI和CINⅡ一Ⅲ组中的阳性表达率高于慢性宫颈炎组(均P/4am、低分化癌、浸润深度>l,2、有淋巴结转移者中NF—KBp50蛋白表达升高,差异有统计学意义(均P<0.05)。③宫颈癌中BRMS1与NF—KBp50蛋白表达水平呈负相关(=0.426,P
3、<0.001)。结论:宫颈癌中BRMS1蛋白与NF—KB蛋白的阳性表达呈负相关,BRMS1蛋白阳性表达逐渐下降、甚至缺失,而NF—KB蛋白阳性表达逐渐升高,与癌细胞的发展、浸润转移密切相关。【关键词】宫颈肿瘤;癌;基因,肿瘤抑制;基因;NF—KB;免疫组织化学;乳腺癌转移抑制基因1ExpressionandClinicalSignificanceofBRMS1andNF-KBinCervicalCarcinogenesisMA0Li,YANGYong-xiu.The历ClinicalMedicineCollegeofLanzhouUniversi
