摘要
目的:研究人乳头瘤病毒16型(HPV16)DNA阳性乳腺良、恶性病变组织中E6和E7蛋白的表达情况。方法:以经PCR筛选证实的HPV16DNA阳性的56例乳癌和41例乳腺良性病变组织为研究对象,采用Westernblotting方法检测HPV16E6和E7蛋白。结果:56例HPV16DNA阳性乳癌组织中,HPV16E6、E7和E6/E7共表达阳性率分别为67.9%(38/56)、75.0%(42/56)和57.1%(32/56);41例HPV16DNA阳性乳腺良性病变组织中,HPV16E6、E7和E6/E7共表达阳性率分别为36.6%(15/41)、43.9%(18/41)和24.4%(10/41)。HPV16DNA阳性乳癌组织中E6、E7和E6/E7共表达阳性率均高于乳腺良性病变组织(χ2分别为9.34,9.70,10.34,P均<0.01)。HPV16DNA阳性乳癌组织中E6、E7和E6/E7共表达阳性率与患者年龄和肿瘤组织学类型无关(P均>0.05),但与淋巴结转移有关(χ2分别为3.88,15.86,9.34,P均<0.05)。结论:HPV16E6和E7蛋白在乳癌发生发展中具有重要作用,并与乳癌淋巴结转移有关。
Aim:To investigate the expressions of human papillomavirus 16 type(HPV16) E6 and E7 proteins in HPV16 DNA-positive breast benign and malignant lesions.Methods:A total of 56 HPV16 DNA-positive breast carcinomatissue and 41 breast benign lesions confirmed by PCR were used to detect HPV16 E6 and E7 proteins using Western blotting assay.Results:In 56 HPV16 DNA-positive breast carcinoma tissue,the positive rates of HPV16 E6,E7,and E6/E7 co-expression were 67.9%(38/56),75.0%(42/56),and 57.1%(32/56),respectively,all higher than those of 36.6% ( 15/41 ) , 43.9% ( 18/41 ) , and 24.4% ( 10/41 ) , respectively, in 41 HPV16 DNA-positive breast benign lesions(χ^2 was 9.34,9.70,10. 34, respectively, P 〈 0.01 ). The HPVI6 E6, E7, and E6/E7 co-expression were associated with lymph node metastasis of patients with breast carcinoma (χ^2 was 3.88,15.86,9.34, respectively, P 〈 0.05 ) , but not with age or histological classification (P 〉0.05 ). Conelusion:HPV16 E6 and E7 proteins may play an important role in the carcinogenesis and progression, and were associated with lymph node metastasis of breast carcinoma.
