THE INFECTION OF EBV FOR CERVICAL EPITHELIUM-A NEW CAUSITIVE AGENT IN THE DEVELOPMENT OF CERVICAL CARCINOMAS?

Epstein-Barr virus was considered as a caustive agent for Burrkitt' s lymphoma and non-malignant B lymphocytes proliferation. The recent studies revealed the striking association of the Infection of EBV with the development of human epithelial tumors. 43 specimens of normal exfoliated cervical epithelial cells, 47 biopsies of chronic cervlcitis and 80 tissue samples of cervical carcinomas were tested for the presences of EBV W fragments by using dot blot hybridization method. The results showed that the detectable rates of EBV DNA sequences In the normal exfoliated epithelium, the chronic cervlcitis and cervical carcinomas were 44.16%, 12.77% and 13.75%, respectively. Eleven EBV positive DNA samples from cervical cancers were also examined for the presence of HPV DNA. The result showed 9 out of 11 were HPV DNA positive, the cultanious infectious rate of both viruses was about 81.81%.In this paper, the EBV genomes existed In the part of biopsies of cervical carcinomas were first reported. The results Imp     

我国人乳头瘤病毒(HPV16Z)基因克隆和鉴定(简报)

分子流行病学资料指出,我国妇女宫颈癌HPV16 DNA同源序列检出率为55.06％,占全部HPV阳性标本的70.83％,提示我国宫颈癌的发生主要与HPV16型感染有关.因此,分离我国HPV16型并研究其生物学功能、致癌特性及其与宫颈癌发生的关系均具有十分重要的意义. 本文作者采用基因克隆手段,以pAt153为载体,从1份来自山西襄垣县宫颈癌高发区宫颈原位癌患

ROLE OF COLPOSCOPY IN THE DIAGNOSIS OF HUMAN PAPI- LLOMAVIRUS INFECTION OF THE UTERINE CERVIX

Among 6706 women screened by cytology, only 9 (0.13%) showed evidence of human pppillomavirus infection (HPVI). In 133 women examined by colposcopy for abnormal cytology or/ and suspected lestions on the cervix, 41.(30. 8%) showed subclinical papillomavirus infection (SPI), while 17. 4% and 5. 3% showed HPVI by histopathology and cytology, respectively. The conformation rate between colposcopy and pathology was 69. 6%. Sixty-nine specimens out of 133 colposcopy piled biopaies were assayed by HPV-DNA dot hybridization with 6B/11, 16, 18 probes to detect the presence of HPV-DNA In the cervical specimens. Thirty-nine (56.5%) gave a positive result. The colposcopic predictive value of positive result for HPVI was 76.7%. The difference between colposcopy (59%) and pathology (20. 5%) is statistically significant (P<0. 01). These results suggest that colposcopy is superior to cytology and hjstopathology for the detection of SPI in the cervix. In colposcopy HPV-DNA positive women, aceto while epithelium was mos     

含人乳头瘤病毒16型E6E7反意基因的假型逆转录病毒对人乳头瘤病毒16型转化细胞生长的抑制作用

构建了一个含人乳头瘤病毒１６型Ｅ６Ｅ７反意基因片断的逆转录病毒载体ｐＨ１９。用Ｌｉｐｏｆｅｃｔｉｎ将ｐＨ１９导入病毒包装细胞ｐＡ３１７，使之产生假型逆转录病毒Ｈ１９。Ｈ１９病毒感染人乳头瘤病毒１６型转化的细胞后，使转化细胞的生长速率和裸鼠体内形成肿瘤的能力均明显下降。     

人乳头瘤病毒感染与发生宫颈癌及非癌宫颈疾患危险性分析

采用斑点杂交技术对２４７份项癌、１４３份非癌宫颈疾患活检组织标本分别进行了人乳头瘤毒６／１１（ＨＰＶ６／１１）、ＨＰＶ１６和１８型ＤＮＡ序列检测，实验结果指出：（１）２４７份癌标本中，ＨＰＶ源序列检出率为６５．９９％，其中ＨＰＶ１６型检为５５．０６％，占全部宫颈癌ＨＰＶ阳性一标本的７１．２８％，分别为该组ＨＰＶ６／１１及１８型感染的４．２５倍和５．６７倍。（２）１４３例非癌宫颈疾患标本中，ＨＰＶ检     

人乳头瘤病毒16型E6E7反义RNA抑制宫颈癌细胞恶性表型的作用

目的研究癌基因的特异性反义ＲＮＡ对癌细胞生长繁殖和恶性程度的影响。方法用逆转录病毒载体将人乳头瘤病毒（ＨＰＶ）－１６Ｅ６Ｅ７反义ＲＮＡ导入ＨＰＶ－１６ＤＮＡ阳性的宫颈癌细胞株ＣａＳｋｉ中，观察该细胞在导入反义ＲＮＡ后其表型特征和在裸鼠体内致癌能力的变化。结果ＨＰＶ－１６Ｅ６Ｅ７反义ＲＮＡ能降低宫颈癌细胞ＣａＳｋｉ的生长速率，抑制其在软琼脂上的集落形成能力，并能明显地抑制其在裸鼠体内的致癌能力。Ｗｅｓｔｅｒｎｂｌｏｔ分析发现ＨＰＶ－１６Ｅ６Ｅ７反义ＲＮＡ能使宫颈癌细胞中病毒ＨＰＶ－１６Ｅ６基因的表达水平降低。结论ＨＰＶ－１６Ｅ６Ｅ７反义ＲＮＡ能使宫颈癌细胞ＣａＳｋｉ恶性表型逆转；由其引起的癌细胞中ＨＰＶ－１６癌基因表达水平的降低可能是癌细胞表型逆转的原因之所在；ＨＰＶ－１６癌基因的表达水平对维持癌细胞的恶性表型起着重要作用。
