expression of the human papillomavirus type 6b l2 open reading frame in escherichia coli: l2-beta-galactosidase fusion proteins and their antigenic properties.human papillomavirus (hpv) type 6b genome contains two large open reading frames (orfs), designated l1 and l2, in a putative late region. these orfs are expected to code for viral structural proteins. to examine antigenic properties of a l2 gene product, we constructed two plasmids which contain n-terminal (l2-n) and internal (l2-i) regions of the hpv6b l2 orf and then each region was expressed in escherichia coli as a fusion protein with e. coli beta-galactosidase (beta-gal). both l2-n/beta-gal ...19872437699
laryngeal papilloma cells in culture have an altered cytoskeleton.we have investigated the effect of human papillomavirus (hpv) transformation on cellular cytoarchitecture. cells from laryngeal papillomas and normal epithelium were cultured in vitro. cytoskeletal components of both types of cells were visualized by immunofluorescence, to determine whether there were any differences in the structure or distribution of the cytoskeleton. there was no significant change in microtubules. two major components of the cytoskeleton, the intermediate filaments and the m ...19872437763
structure, dnasei hypersensitivity and expression of integrated papilloma virus in the genome of hela cells.three integrated copies of human papilloma virus-18 (hpv-18) have been identified in hela dna as hindiii bands. hpv-18 has no hindiii restriction site in its genome. the three segments: a, 8.4 kb; b, 7.9 kb and c, 5.8 kb, have an incomplete viral genome. all of them have most of the 1.1-kb bamh1 non-coding fragment of hpv-18, which seems to contain the viral origin of replication and regulatory elements. two of the segments (a and b) have a common 5'-end break-point in the viral genome within th ...19872439332
transformation of human fibroblasts and keratinocytes with human papillomavirus type 16 dna.human keratinocytes and fibroblasts isolated from foreskin were transformed by transfection with recombinant human papillomavirus type 16 (hpv16) dna. the transformed cells exhibited an extended (fibroblasts) or indefinite (keratinocytes) life-span compared with that of normal controls. in addition, hs27, a human fibroblast cell line previously transfected with origin-defective simian virus 40, was successfully transfected. hpv16 sequences were stably maintained in the cells, and extensive ampli ...19872434663
multifocal squamous neoplasia of the female genital tract: significance of human papillomavirus infection of the vagina after hysterectomy.six hundred sixteen women with a history of hysterectomy were examined for the presence of human papillomavirus deoxyribonucleic acid (dna) in vaginal smears using filter in situ hybridization. one hundred twenty patients had had hysterectomy for cervical intraepithelial neoplasia and invasive neoplasia, 54 for noncervical anogenital cancer, and 442 for benign uterine disorders. human papillomavirus dna was detected in 18% of all vaginal smears. a history of cervical neoplasia was associated wit ...19872819794
human papillomavirus-associated lesions of the penis: colposcopy, cytology, and histology.the diagnosis and therapy of human papillomavirus infections in men is of potential benefit because it may decrease the reservoir of virus from which genital condylomata or squamous neoplasia may arise in women. to investigate the efficacy of diagnostic methods, we examined the 127 male sexual partners of 127 women with cervical intraepithelial neoplasia. eighty-three mostly asymptomatic men (65%) had from one to 50 (median three) small (median 3 mm) human papillomavirus-associated lesions consi ...19872819795
human papillomavirus deoxyribonucleic acid in lesions of the female genital tract: evidence for type 6/11 in squamous carcinoma of the vulva.tissue specimens from 51 patients with genital condyloma acuminata or invasive cervical or vulvar carcinomas were analyzed for the presence of human papillomavirus deoxyribonucleic acid (dna) using the dot blot technique. of ten condylomas, 80% contained dna related to human papillomavirus 6 or 11. sixty percent had evidence of dna related to human papillomavirus 16, and 30% contained dna related to human papillomavirus 18. of 24 squamous cervical carcinomas, 58% had human papillomavirus type 16 ...19872819798
human papillomavirus dna in squamous cell carcinomas of the larynx demonstrated by in situ dna hybridization.a series of 116 consecutive laryngeal squamous cell carcinomas were analyzed using an in situ dna hybridization technique with 35s-labelled human papillomavirus (hpv) dna probes to demonstrate the dna of hpv types 6, 11, 16 and 30, in routinely processed, paraffin-embedded biopsies. the lesions were also assessed on light microscopy for hpv-suggestive morphological features, and by indirect immunoperoxidase (ip-pap) technique to demonstrate the expression of hpv structural proteins (viral antige ...19872819803

evolution of human papillomavirus infections in the uterine cervix during a long-term prospective follow-up.a series of 513 women presented with cervical human papillomavirus (hpv) infections (with or without cervical intraepithelial neoplasia; cin) have been prospectively followed up since 1981 (mean 25.6 months), at 6-month intervals, by colposcopy with pap smears and/or punch biopsies. the latter were analyzed by light microscopy, as well as immunohistochemically for hpv structural proteins. hpv dna typing was accomplished by southern blot, spot, and in situ hybridization techniques using the dna p ...19872820450
detection of human papillomavirus-6 in primary carcinoma of the urethra in men.the authors report a case of primary urethral carcinoma which seems to be linked to human papillomavirus (hpv) infection. southern blot hybridization of phosphorus 32 (32p)-labeled dna extracted from the cancer tissue gave a positive reaction with hpv-6. specimens of the tumor material subjected to in situ hybridization with 3h-labeled hpv-6 dna showed numerous tumor cell clusters with clearly labeled nuclei. using immunoperoxidase staining the authors found papillomavirus structural antigen wit ...19872820563
cytologic and histologic manifestations of human papillomavirus infection of the female genital tract and their clinical significance.the historical developments in the recognition of the role of human papillomavirus (hpv) infection in cells and tissues of the female genital tract are briefly summarized. the identification of a specific marker cell, the koilocyte, has led to initial studies of frequency and biologic significance of neoplastic lesions of the uterine cervix associated with hpv. by molecular virology techniques, over 40 types of hpv have been identified and their tissue affinity determined. types 6, 11, 16, 18, a ...19872820565
causes and management of cervical intraepithelial neoplasia.the evidence for human papillomavirus (hpv) playing a role in the pathogenesis of lower genital neoplasia is reviewed. it is likely that this group of viruses is etiologically important. it is suggested that cervical lesions be diagnosed as flat condyloma if they contain hpv types six or 11 and as cervical intraepithelial neoplasia (cin) if they are confined to the epithelium and contain hpv types 16 or 18 or other types associated with neoplasia. patients with a papanicolaou (pap) smear or clin ...19872820566
detection of low copy human papilloma virus dna and mrna in routine paraffin sections of cervix by non-isotopic in situ hybridisation.in analysing human papilloma virus (hpv) infection of the cervix in formalin fixed paraffin sections by non-isotopic in situ hybridisation two main problems were found: detachment of sections from the glass during hybridisation and probe detection; inadequate sensitivity and inability to assess sensitivity of the in situ procedure. the first problem was investigated by assessing the efficiency of various tissue adhesives individually and in combination. the second problem was addressed by optimi ...19872821078
demonstration of human papillomavirus dna in oral condyloma acuminatum.condyloma acuminatum arising on oral mucous membranes exhibits distinct histopathological features that allow for differentiation from the more common squamous papilloma. these lesions are parakeratinized with cryptic invagination of cornified cells extending into an acanthotic spinous cell layer. superficial spinous layer koilocytosis is a prominent feature and the condylomatous papillomas exhibit a tendency for sessile architecture. among 62 instances, the average age was 39.7 years with a pre ...19872821213
human papillomavirus standardization and dna cytophotometry in cervical intraepithelial neoplasia.human papillomavirus (hpv) standardization and dna cytophotometry were carried out in 29 cases of cervical intraepithelial neoplasia (cin) grades i-iii. a prognostically unfavorable dna distribution pattern with an aneuploid stemline was found in 14 of the 16 dysplasias with hpv types 16 and 18, while in 11 of 13 dysplasias with hpv types 6 and 11 there was a favorable dna distribution with a euploid-polyploid stemline. among 178 colposcopically, cytologically and histologically confirmed cervic ...19872821252
oncogenic association of specific human papillomavirus types with cervical neoplasia.molecular hybridization analysis of human papillomavirus (hpv) dna from 190 cervical biopsy specimens from women in the united states, brazil, and peru revealed viral sequences in 2 (9%) of 23 biopsy specimens of normal mature squamous epithelium, 7 (44%) of 16 biopsy specimens of metaplastic squamous epithelia, 60 (77%) of 78 cervical intraepithelial neoplasia (cin), 57 (89%) of 64 invasive squamous carcinomas, and 8 (89%) of 9 endocervical adenocarcinomas. hpv typing by dna hybridization revea ...19872821311
chromosomal integration sites of human papillomavirus dna in three cervical cancer cell lines mapped by in situ hybridization.metaphase chromosomes of three cervical cancer cell lines (hela, caski, siha) were subjected to in situ hybridizations with the dna of human papillomaviruses (hpv) types 16 and 18, respectively. previous studies have demonstrated multiple copies of hpv 18 dna in hela and of hpv 16 dna in caski cells, but only 1-2 hpv 16 copies in cells of the siha line. the viral dna persists in an integrated state (schwarz et al 1985). analysis of the integration sites revealed at least 11 chromosomal sites of ...19872821369
the morphology of butchers' warts as related to papillomavirus types.hand warts were studied in 160 butchers. clinical and histological studies were performed in 190 warts and virological studies in 165 warts from 104 butchers. since we found almost perfect correlation between the histological pattern and the type of infecting virus, it was possible to evaluate the virus types in a further 39 of 56 butchers without virological studies, on the basis of the histology of the warts. the most common infection was with hpv-2 (human papilloma virus) and hpv-7. thirty-th ...19872821930
detection of human papillomavirus dna in biopsies of human oral tissue.we have employed molecular probes produced from dna fragments of human papillomavirus, cloned into prokaryotic vectors, to detect virus nucleic acid sequences in extracts of human oral tissues. the study was conducted with duplicate coded snap-frozen tissue biopsies from which frozen sections had been taken to accurately assess the pathology of each particular sample. the results show that a large proportion of the oral biopsies contained dna which hybridized to the viral dna probes, even under ...19872822070
natural killer cells in cervical intraepithelial neoplasia and human papillomavirus infection.a semiquantitative immunocytochemical study of natural killer (nk) cells in cervical mucosa was performed by the immunoperoxidase technique using anti-leu-7 and anti-leu-11 monoclonal antibodies. nk cells were present in two of the five normal controls and five of six specimens showing human papillomavirus (hpv) infection. of the 12 cin studied, six were positive for both leu-7 and leu-11 staining and three were positive for leu-11 alone. nk cells were found predominantly in the subepithelial st ...19872822078
[histological aspects of lesions of the cervix uteri correlated with different types of human papillomavirus].cervical biopsies from 66 women presenting an abnormal smear, with hpv related features were studied and histologic features were correlated to the hpv type, as determined by molecular hybridisation studies. hpv dna sequences were evidenced in 13 of 19 lesions corresponding to exophytic or flat condyloma (hpv type 16 in seven cases, hpv type 11 in four cases, as yet uncharacterized hpv types, hpv x, in two cases). fourty biopsies were histologically interpreted as cin, on the basis of atypical m ...19872822182
sensitivity of the cytologic diagnosis of cervical condyloma in comparison with hpv-dna hybridization studies.the cytologic diagnosis of cervical condyloma is based on criteria developed over the last 10 years. it has now become possible to document the presence of human papilloma virus (hpv) dna directly in cervical swabs by the highly sensitive technique of dna filter hybridization in situ. the purpose of this article is to evaluate critically the empirically established cytologic criteria of condyloma by comparing them with hpv-dna hybridization studies in the same material. the results of this study ...19872822367
case-control study of human papillomaviruses and cervical cancer in latin america.human papillomavirus (hpv) types 16 and 18 have been implicated as risk factors for cervical dysplasia and neoplasia. however, most studies have been observational, uncontrolled and conducted in populations at low risk for invasive cancer. we report a pilot case-control study of incident invasive cervical cancer in panama, costa rica and bogota, colombia. between july and september 1985 we enrolled 46 consecutive newly diagnosed invasive cervical cancer cases and 51 age-matched control women. su ...19872822583
in situ localization of human papilloma virus type 16 dna in a metastasis of an endocervical adenocarcinoma.metastatic tissue from an endocervical adenocarcinoma was examined for human papilloma virus (hpv) dna sequences. southern blot analysis with 32p-labeled viral probes revealed the presence of about 150 copies of hpv-16 dna per cellular genome. dna in situ hybridization of frozen sections with biotinylated probes showed that hpv-16 dna was exclusively detectable in the nuclei of the malignant epithelial cells and not in the stroma.19872822599
herpes simplex virus and human cytomegalovirus: their role in morphological transformation and genital cancers.herpes simplex virus (hsv) and human cytomegalovirus (hcmv) are candidates for the induction of premalignant or malignant disease. morphological transformation studies have failed to demonstrate a viral oncogene, a virus-coded transforming protein or any sequence of dna that uniquely transforms cells according to one-hit kinetics. thus the mechanism of transformation is complex. the transformed cells are, however, all oncogenic in the host animal and in immunocompetent mice. direct evidence for ...19872822840
human papillomavirus (hpv) in oral squamous cell papillomas.one hundred and forty oral squamous cell papillomas (scps) were subjected to immunocytochemical staining for papillomavirus antigen using the immunoperoxidase-pap method 41% of the oral squamous papillomas showed positive intranuclear staining, 50% were negative and the remaining 9% showed both intranuclear and cytoplasmic staining. in view of these findings it is suggested that a review of the etiology of lesions diagnosed as oral scps should be considered.19872822883
the e6-e7 region of human papillomavirus type 18 is sufficient for transformation of nih 3t3 and rat-1 cells.plasmids containing the e6 and e7 open reading frames of human papillomavirus type 18 expressed from an autologous transcriptional control region were sufficient for transformation of nih 3t3 and rat-1 cells. transformation by these sequences did not always involve morphological alterations even though anchorage-independent growth occurred at a high frequency. in these cells, the efficiency of transformation by the e6 and e7 construct was equivalent to or, in most cases, better than that observe ...19872822969
hpv dna detection in tumours of the head and neck: a comparative light microscopy and dna hybridization study.a series of 22 squamous cell carcinomas (4 cases grade 1; 11 cases grade 2; 7 cases grade 3) of the oral cavity (13 cases), (naso-)pharynx (5 cases) and larynx (4 cases) were studied by conventional light microscopy and filter (dot blot) hybridization for the detection of human papillomavirus (hpv) dna. in 4 carcinomas, tumour-free tissue from the resection margins of the surgical sample was examined in addition to the tumour specimen. the same kind of investigation was carried out on 4 oral leu ...19872823203
