Western blot of the protein extracts of 31 samples of breast cancer tissues and their normal (not cancerous ) tissues a little far away from them in the same individuals showed that, in the majority of the tests (71%), centromere protein CenpG over expressed in breast cancer tissues. And moreover, a kind of protein component whose molecular weight is 43 kd, and which can be recognized by anti-CenpG serum was found in two of the cancer samples. The results suggested that CenpG (together whith it, there may be other relative components),which has been found and named recently, may be related to cancer,and its differential expressing is probably related to malignant cell proliferation.展开更多

目的:探讨血清抗着丝粒蛋白F抗体(anti-centromere protein F antibody,anti-CENPF)在乳腺癌中的临床价值。方法:收集100例初诊乳腺癌(breast cancer,BC)患者、40例乳腺良性疾病(non breast cancer,non-BC)患者和40名健康体检者(healthy...目的:探讨血清抗着丝粒蛋白F抗体(anti-centromere protein F antibody,anti-CENPF)在乳腺癌中的临床价值。方法:收集100例初诊乳腺癌(breast cancer,BC)患者、40例乳腺良性疾病(non breast cancer,non-BC)患者和40名健康体检者(healthy control,HC)血清,采用酶联免疫吸附试验检测血清中的anti-CENPF水平,同时化学发光法测定血清糖类抗原153(carbohydrate antigen 153,CA153)的水平。结果:BC组血清anti-CENPF水平高于non-BC组和HC组,差异有统计学意义(P<0.05)。anti-CENPF和CA153诊断乳腺癌中的曲线下面积(area under the curve,AUC)分别为0.714和0.672,两者联合检测的AUC为0.739。有淋巴结转移、远处转移或者人表皮生长因子受体2(human epidermal growth factor receptor-2,HER-2)阴性的乳腺癌患者血清anti-CENPF浓度明显升高(P<0.05)。不同肿瘤大小、临床分期、分子分型乳腺癌患者血清anti-CENPF水平比较,差异有统计学意义(P<0.05)。组间比较显示Ⅳ期和Ⅲ期血清anti-CENPF浓度高于Ⅰ期和Ⅱ期,HER-2过表达型、Luminal B型血清anti-CENPF水平低于三阴性乳腺癌(triple negative breast cancer,TNBC)患者。雌激素受体(receptors estrogen,ER)阳性的乳腺癌患者中,HER-2阴性组的anti-CENPF浓度高于HER-2阳性组,差异有统计学意义(P=0.026)。结论:血清antiCENPF在乳腺癌的诊断、临床分期及分子分型中发挥了重要作用,其水平可能与乳腺癌预后呈负相关,有望成为乳腺癌潜在的疾病标志物。展开更多
