子宫颈癌组织中HPV16癌基因及p53基因的检测   总被引:4,自引:0,他引:4  
利用HPV16E6、E7基因特异性引物,PCR技术及抗癌基因p53外显子7特异性引物,PCR-SSCP技术对35例进展期子宫颈癌组织进行研究,发现:(1)35例标本中HPV16E6、E7DNA的总检出率为71.42%(25例),其中同时检出E6、E7为31.42%(11例),另外8.57%及31.42%(3例及11例)仅分别检出E6、E7序列。(2)全组未见1例有p53基因外显子7的点突变及等位基因缺失。该结果说明HPV16与本地区妇女子宫颈癌发生有密切关系,并且癌组织中HPV16E6、E7亚基因的分布是不均一的,p53基因外显子7的改变并不常见。在实验中我们还建立了使用生物素标记的dUTP进行PCR-SSCP的技术。  相似文献

Samples from patients with genital condyloma acuminata or with cervical condylomas and/or dysplasia and from women without cytological/clinical evidence of cervical affection were examined by dot blot DNA hybridization or the polymerase chain reaction (PCR). The PCR was much more sensitive than dot blot, more than doubling the human papilloma virus (HPV) findings. HPV DNA, mainly HPV 6/11, was detected in 18 of 19 biopsies of condyloma acuminata, whereas HPV 16 was most frequently detected in the 21 cervices (76%) with condyloma and/or dysplasia. HPV 16 was detected in eight of 103 cervical smears with no signs of infection. The prevalence of HPV 16 in cervical samples was somewhat higher than expected. This suggests that, in Oslo, HPV 16 is a common HPV type in women with cytologically normal cervices. HPV 18 was relatively rare and was detected only in combination with other HPVs.  相似文献

Accurate and internationally comparable human papillomavirus (HPV) DNA genotyping is essential for HPV vaccine research and for HPV surveillance. The HPV Laboratory Network (LabNet) has designed international proficiency studies that can be issued regularly and in a reproducible manner. The 2011 HPV genotyping proficiency panel contained 43 coded samples composed of purified plasmids of 16 HPV types (HPV6, -11, -16, -18, -31, -33, -35, -39, -45, -51, -52, -56, -58, -59, -66, -68a, and -68b) and 3 extraction controls. Tests that detected 50 IU of HPV16 and HPV18 and 500 genome equivalents for the other 14 HPV types in both single and multiple infections were considered proficient. Ninety-six laboratories worldwide submitted 134 data sets. Twenty-five different HPV genotyping assay methods were used, including the Linear Array, line blot/INNO-LiPA, PapilloCheck, and PCR Luminex assays. The major oncogenic HPV types, HPV16 and HPV18, were proficiently detected in 97.0% (113/116) and 87.0% (103/118) of the data sets, respectively. In 2011, 51 data sets (39%) were 100% proficient for the detection of at least one HPV type, and 37 data sets (28%) were proficient for all 16 HPV types; this was an improvement over the panel results from the 2008 and 2010 studies, when <25 data sets (23% and 19% for 2008 and 2010, respectively) were fully proficient. The improvement was also evident for the 54 laboratories that had also participated in the previous proficiency studies. In conclusion, a continuing global proficiency program has documented worldwide improvement in the comparability and reliability of HPV genotyping assay performances.  相似文献

To evaluate the importance of high-risk human papillomavirus (HPV) types in in situ and invasive adeno- and adenosquamous carcinomas (ACISs/ACs, and ASCISs/ASCs) of the cervix uteri, we analyzed HPV infection and HPV 16- and HPV 18 E6/E7 oncogene expression in different histologic subtypes. Using the polymerase chain reaction (PCR) technique, 29 of 33 (88%) ACISs, 2 of 2 (100%) ASCISs, 46 of 54 (85%) ACs, and 8 of 10 (80%) ASCs were found to be HPV 16- and/or HPV 18-positive. In 25 of 35 (71%), 10 of 35 (29%), and 4 of 35 (11%) ACISs/ASCISs, HPV 16, HPV 18, and HPV 16 and HPV 18 were detected, respectively. Invasive ACs/ASCs were more frequently infected with HPV 18 (36 of 64, 56%) than with HPV 16 (28 of 64, 44%). Ten (16%) of these cases were positive for HPV 16 and HPV 18. In ACISs/ASCISs, HPV 16 oncogene expression predominated (62%) relative to HPV 18 (25%) expression, whereas in invasive ACs/ASCs, only 21% of the cases expressed HPV 16, but 48% of the cases expressed HPV 18 oncogenes. Thus, detection of HPV 18 in ACISs/ASCISs might be associated with an increased risk of progression. HPV oncogene expression was not dependent on histologic subtype of in situ or invasive AC. Normal glandular epithelia and glandular dysplasias (GDs, n = 4) were always negative concerning HPV oncogene expression. In HPV 16- and HPV 18-double-infected cases, HPV 18 oncogene expression was most frequently detected, and we did not find a coexpression of HPV 16- and HPV 18-specific oncogenes in purely glandular lesions or in cases with an additional CIN (cervical intraepithelial neoplasia) II or CIN III. HPV E6/E7 expression of the same HPV type in both in situ or invasive ACs and associated CIN II/III suggest that these lesions might be histogenetically related.  相似文献

Samples taken from 101 healthy pregnant women (49 over and 52 under the 20-week gestational period) and 108 healthy nonpregnant women were tested for human papillomavirus (HPV) types. Using 6, 11, 16, and 18 HPV DNA probes, 3-5 x 10(5) exfoliated cells scraped from the cervix were tested by filter in situ hybridization (FISH). Thirty-five of the pregnant women (34.6%) had evidence of the presence of HPV DNA: with 11.8% (12/101) HPV 6; 7.9% (8/101) HPV 11; 8.9% (9/101) HPV 16; and 5.9% (6/101) HPV 18 positivity. HPV DNA was detected in 20.4% (22/108) of the non-pregnant women. Compared with the healthy, nonpregnant group, the higher level of asymptomatic cervical HPV infection was mainly due to the accumulation of HPV 16 and 18 nucleic acids during the gestational period: with detection of HPV 16 in 8/49 cases (16.3%) and of HPV 18 DNA sequences in 4/49 (7.6%) cases. Screening 6-8 weeks after delivery indicated a decline of HPV positivity. Of the 4/12 HPV type 16 positive mothers, only one retained the presence of HPV 16 DNA, whereas neither of the 2/12 type 18 positive women reacted after birth with the type 18 radioactive probe.  相似文献

Papanicolaou (Pap)-stained cervical specimens from 160 squamous lesions were processed for the detection of human papillomavirus (HPV) DNA by an in situ hybridization (ISH) assay. Three biotinylated HPV DNA probes were employed, each containing HPV genotypes 6/11, HPV genotypes 16/18, or HPV genotypes 31/35/51. The HPV etiology of 86 lesions was ascertained (53.8%). In 74 out of 135 (58.8%) HPV-typed low-grade squamous intraepithelial lesions (SILs), HPV 6/11 was found in nine (6.6%), HPV 16/18 in 46 (34.2%), and HPV31/35/51 in 19 lesions (14.1%); in 11 out of 18 HPV-typed high-grade SILs (61.1%), seven lesions (38.9%) were typed for HPV 16/18 and four (22.2%) for HPV 31/35/51. Of seven invasive carcinomas, only one (14.3%) reacted with the HPV 16/18 DNA probe. A cohort of 124 low-grade SILs was followed cytologically for a year. The results of this study are discussed in light of HPV type association and therapy. Diagn Cytopathol 1994; 11:28–32. © 1994 Wiley-Liss, Inc.  相似文献

Since 2012, testing high‐risk (HR)HPV has been used as the primary screening test for women ≥35 years attending the organized cervical cancer screening program in the city of Tampere. We evaluated the contribution of HPV16/18 genotyping. Data from 2012 and 2013, and the follow‐up samples in 2013 and 2014, respectively, were analyzed. Abbott RealTime High‐Risk HPV test detecting 14 HRHPV genotypes combined with concurrent genotyping for HPV16 and HPV18 was used. HPV was positive in 794 samples out of 11 346 HPV tested women (7%). HPV16/18 was represented in 22% of HPV‐positive cases. Negative cervical cytology (NILM) was reported in 51% of HPV‐positive samples. HPV16/18 genotype was accompanied with 50% of HSIL/ASC‐H cases. The predominance of HPV16/18 in higher grade lesions was even more evident in cervical biopsies as 57% of CIN3 cases were associated with HPV16/18, and only 20% of carcinomas were associated with nonspecified high‐risk (NSHR) genotypes. In agreement with previous studies HPV16/18 genotypes caused higher grade cytological and histological changes/pathologies than NSHR genotypes in primary screening. Nevertheless, the majority of HRHPV genotypes detected in the screened population were nonHPV16/18, and especially within persistent infections, precancerous lesions were found also among women with NSHR genotypes.  相似文献
