presence of human papilloma virus types 16 and 18 in genital warts and cervical neoplasias.certain types of human papilloma viruses (hpv) are associated with human genital proliferative diseases, and among them hpv16 and hpv18 seem to play an important role in the occurrence of cervical cancer. we used restriction enzyme analysis and molecular hybridization, in order to investigate the type of viral infection and the physical state of viral dna in gynecological benign, pre-malignant and malignant lesions. hpv6/11 specific sequences could only be detected as episomes and this in benign ...19882835559
detection of human papillomavirus capsid antigens in various squamous epithelial lesions using antibodies directed against the l1 and l2 open reading frames.hpv6 and hpv16 infect the squamous epithelium of the genital tract and are thought to be involved in the pathogenesis of benign and malignant lesions. hpv6 is primarily found in benign condylomas whereas hpv16 is present in dysplasias and in invasive squamous cell carcinomas. to examine the expression of the major and minor capsid proteins in these lesions polyclonal antisera directed against bacterially derived fusion proteins harboring different restriction fragments of the l1 and l2 orfs of h ...19882835863
genital warts, papillomaviruses, and genital malignancies.human papillomavirus (hpv) infections of the genital tract are widespread and often subclinical. of about a dozen genital tract hpvs, types 16 and 18 are strongly associated with squamous cell carcinoma of the cervix and of other sites in the lower genital tract. in invasive cervical cancers, the viral genomes are often integrated into the cellular dna and are transcriptionally active. these viruses, with additional cofactors, play a role in genital tract malignancies.19882835929
the human papillomavirus type 16 e7 gene encodes transactivation and transformation functions similar to those of adenovirus e1a.clinical and epidemiological data have implicated the human papillomaviruses (hpvs) as having an etiologic role in some anogenital malignancies, with hpv-16 being most frequently (greater than 60%) detected in cervical carcinoma. hpv-16 is actively transcribed in the cancers; the most abundant transcripts map to the e6 and e7 early open reading frames. evidence is presented that the hpv-16 e7 open reading frame encodes transcriptional transactivation and cellular transformation functions analogo ...19882836062
anal cancer in women.we studied predisposing factors in 56 women with anal cancer, comparing them with 56 matched controls drawn from the population. a detailed pretested questionnaire was administered to each study subject in a structured interview and blood was drawn for detection of herpes simplex virus antibodies by radioimmunoassay. pathologic material from cases was obtained and evidence of human papilloma virus infection was sought. by univariate analyses we found associations between anal cancer and positive ...19882836255
screening of premalignant cervical lesions for hpv 16 dna by sandwich and in situ hybridization techniques.a series of 97 cervical smears and 69 directed punch biopsies derived from 84 consecutive women prospectively followed-up for cervical hpv (human papillomavirus) infections were studied using the sandwich hybridization and in situ hybridization techniques with hpv 16 dna probes. the aim was to test the sensitivity and applicability of these two techniques in routine diagnosis of cervical hpv infections from smears. as a measure of specimen adequacy, the number of cells recovered in the cervical ...19882836276
transformation of rat 3y1 cells by human papillomavirus type-18 dna.rat 3y1 cell cultures transfected with human papillomavirus type-18 (hpv 18) dna produced foci of morphologically transformed cells capable of anchorage-independent growth. analyses of the transformed cell clones obtained after transfection with ecori-cleaved linear hpv 18 dna showed that, although the viral dnas integrated in the cell dna had rearrangements (probably around the sites of integration), they appeared to retain the putative transcriptional control region and the downstream area con ...19882836322
sensitivity of in situ hybridization techniques using biotin- and 35s-labeled human papillomavirus (hpv) dna probes.in order to evaluate the sensitivity of our modified in situ dna hybridization technique using biotinylated probes, formalin fixed, paraffin embedded biopsies from 20 cervical lesions known to contain human papillomavirus (hpv) dna were re-examined by the technique using both 35s-labeled- and biotinylated hpv dna probes. the probe concentrations as well as the detection limits of biotin probing were screened by spotting known amounts of hpv 16 dna on nylon filter, and allowed to hybridize with b ...19882836460
papillomaviruses: the current status in relation to oral disease.human papillomaviruses of different types are associated with a variety of benign oral lesions and may be associated with some premalignant and malignant oral lesions. however, since it is now clear that a variant of human papillomavirus 16 is harbored by normal oral mucosa, as well as by premalignant and malignant lesions, such associations may not necessarily always be causal. the rapid progress of recent research in this field is reviewed, with particular reference to oral disease, and the cu ...19882836772
oral squamous papillomas: detection of hpv dna by in situ hybridization.oral squamous papillomas were segregated from other papillary lesions on the basis of histopathologic features. twenty representative papillomas were evaluated for the presence of papillomavirus genus-specific antigen with the use of an immunoperoxidase technique. these same tumors were analyzed for human papillomavirus (hpv) types 2, 4, 6, and 11 with biotinylated full-length double-stranded dna probes by in situ hybridization. only one case exhibited papillomavirus antigen reactivity. alternat ...19882836773
expression of the e2 open reading frame of papillomaviruses bpv1 and hpv6b in silkworm by a baculovirus vector.to produce and characterize the nature of the e2 protein of papillomaviruses, we have developed a system to express the dna sequence containing an open reading frame (orf) as a fusion protein in cultured insect cells and silkworms. the dna fragments of the e2 orf predicted from the dna sequence of bovine papillomavirus type 1 and human papillomavirus type 6b were linked to the n-terminal part of polyhedrin gene of the baculovirus bombyx mori nuclear polyhedrosis virus (bmnpv) vector. hybrid prot ...19882837019
a monoclonal antibody that binds to tumor-associated antigens of exfoliated cells in the smears of patients with cervical intraepithelial neoplasia.the reactivity of ce 407, a monoclonal antibody (mab) known to bind to the cells of invasive cervical squamous cell carcinoma, was tested by the immunoperoxidase technique in samples from precursor lesions with and without associated condylomatous atypia. antibody ce 407 bound with a high frequency to cells from cases of cervical intraepithelial neoplasia (cin) and to cells showing condylomatous changes. antibody ce 407 gave a positive reaction in 16 (64%) of 25 patients with cin only. when the ...19882837032
comparison of the cytobrush and cotton swabs in sampling cervical cells for filter in situ hybridization detection of human papillomavirus types 16 and 18 dna.the cytobrush was compared with the cotton swab for collecting samples used to detect human papillomavirus (hpv) types 16 and 18 dna by filter in situ hybridization. the study design entailed collecting two endocervical and one vaginal fornix sample from each of 200 women admitted to a colposcopy clinic. no difference was found in the hpv positivity rates in samples obtained with the two collection instruments. there was good agreement (91.5%) in the detection of viral dna between the first and ...19882837033
urethral cytology of cytobrush specimens. a new technique for detecting subclinical human papillomavirus infection in men.cytologic examination of urethral smears prepared with the cytobrush and colposcopic examination of the penis were performed in 53 male partners of women with cervical human papillomavirus (hpv) infections and in 14 healthy controls. a diagnosis of hpv infection was recorded in 28 subjects (52.8%). cytology was positive in 26 cases (49%) and colposcopy was positive in 5 cases, with both tests positive in 3 cases. no controls were positive by cytology or colposcopy. these findings suggest that ur ...19882837034

detection of infection by human papillomavirus in genital condylomata. a comparison study using immunocytochemistry and in situ nucleic acid hybridization.one hundred eighty exophytic genital lesions clinically suspicious for infection by human papillomavirus (hpv) were analyzed by hematoxylin and eosin light microscopy, immunocytochemistry for hpv capsid antigen; and in situ nucleic acid hybridization for hpv messenger rna (mrna). of 96 cases morphologically consistent with infection by hpv, 53% were antigen-positive, and 83% were mrna positive (p less than 0.01). of 55 cases suggestive but not diagnostic of hpv infection, 13% were antigen-positi ...19882833093
human papillomavirus type 16 in multifocal neoplasia of the female genital tract.we examined lesions from six women with multifocal neoplasia of the lower genital tract (vulva and cervix or vulva and vagina) for the presence of human papillomavirus (hpv) dna sequences by dna-dna in situ hybridization. cervical tissue specimens from four of the five women with carcinoma in situ (cis) of the cervix were found to contain hpv type 16 dna sequences. vulvar lesions from three of these women also contained hpv-16 dna and were histologically consistent with cis. in each instance, hy ...19882832336
a clinical, histopathologic, and molecular biologic investigation of vulvar intraepithelial neoplasia.the spectrum of vulvar intraepithelial neoplasia (vin) was investigated with human papillomavirus (hpv) dna probes by southern blot hybridization technique. the results of vulvar tissue examinations from 25 patients were compared to prior genital and systemic diseases, clinical presentation, and histopathologic manifestations. the presence of hpv dna in these lesions was largely associated with multifocality of the lesions, the presence of synchronous and metachronous multicentric genital neopla ...19882832337
advantage of human papillomavirus typing in the clinical evaluation of genitoanal warts. experience with the in situ deoxyribonucleic acid hybridization technique applied on paraffin sections.genitoanal warts are predominantly induced by human papillomavirus (hpv) types 6, 11, 16, and 18. a strong association has been established between infection by hpv 16 and hpv 18 and the subsequent development of cancer in the uterine cervix. therefore, a clinical challenge exists with respect to identification of patients harboring the latter type of high-risk hpv types. the present study on 108 men with genitoanal warts focuses on whether reliable gross and/or histopathologic criteria exist to ...19882832454
updated approach to screening for cervical cancer in older women.elderly women are inadequately screened for carcinoma of the cervix. patient, physician, and laboratory factors are responsible for this "performance gap." patients may be unaware of the need for routine screening; physicians other than obstetricians and gynecologists may not view cervical cancer screening as appropriate; and laboratories are under scrutiny for their quality control problems. data from a maryland study demonstrates the barriers to screening for the elderly: they receive sporadic ...19882832258
transcriptional differences of the human papillomavirus type 16 genome between precancerous lesions and invasive carcinomas.human papillomavirus type 16 (hpv16) genome dna and its transcripts in biopsied cervical neoplasias were analyzed by simultaneous extraction of dna and rna from one biopsied sample. southern blot analysis revealed that 5 of 20 cervical intraepithelial neoplasias (cins) contained hpv16 dnas existing primarily as episomes and two of seven invasive carcinomas harbored hpv16 genome sequences integrated into the host dna. northern (rna) blot analysis showed that the hpv16 genome sequences were transc ...19882828651
identification of the e5 open reading frame of human papillomavirus type 16.sequencing of the e5 open reading frame (orf) of human papillomavirus type 16 revealed an additional nucleotide, a thymidine residue, at position 3903 compared with the original sequence (seedorf et al., virology 145:181-185, 1985). the additional t had two effects; first, in reading frame 2, in which the original e5 orf was predicted, the additional t changed the reading frame downstream of position 3903 to create an orf, which we designated e5, that terminated at position 4018 and potentially ...19882828656
inducible and constitutive enhancer domains in the noncoding region of human papillomavirus type 18.the noncoding region of human papillomavirus type 18 (hpv-18) is shown to contain at least three enhancer elements. two of these elements are responsive to papillomavirus-encoded trans-acting factors, and the third element functions as a constitutive enhancer, requiring only cellular factors for activity. the first enhancer (ie2) is located proximal to the e6 cap site and is responsive to papillomavirus e2 trans-activator. the second enhancer (ie6) is located approximately 500 base pairs upstrea ...19882828662
papillomavirus in the vapor of carbon dioxide laser-treated verrucae.vapor produced by the carbon dioxide laser during the vaporization of papillomavirus-infected verrucae was analyzed for viral dna content. two models were used for evaluation: an in vitro cutaneous bovine fibropapilloma and an in vivo human verruca model. four bovine fibropapillomas were exposed to various laser parameters with power densities of 38,200 to 130 w/cm2 and energy fluences of 3820 to 130 j/cm2. the generated vapor was collected in a chamber in line with a vacuum system. hybridizatio ...19882828703
development of cervical and vaginal squamous cell neoplasia as a late consequence of in utero exposure to diethylstilbestrol.during the last 14 years, several articles have given contradictory reports on prevalence rates of squamous cell neoplasia of the cervix and vagina in diethylstilbestrol (des)-exposed progeny. in 1984, the des-adenosis (desad) project found that the incidence of cervical and vaginal intraepithelial neoplasia in des-exposed daughters was twice as high as in a comparison group of unexposed women. this was also associated with a higher rate of herpes simplex virus and human papillomavirus infection ...19882829071
cloning and characterization of a papillomavirus associated with papillomas and carcinomas in the european harvest mouse (micromys minutus).individuals in a colony of european harvest mice (micromys minutus) were diagnosed with a variety of skin tumors including papillomas, trichoepitheliomas, and sebaceous carcinomas. papillomavirus group-specific antigens and viruslike particles were detected in the papillomas. a 7.6-kilobase supercoiled circular dna, which was cleaved once by ecori, was visualized in papilloma extracts by low-stringency southern blot hybridization with a bovine papillomavirus type 2 probe. the molecule was cloned ...19882824849
progression of the phenotype of transformed cells after growth stimulation of cells by a human papillomavirus type 16 gene function.alteration of the growth properties of the established murine fibroblast cell lines nih 3t3 and 3y1 was studied in monolayer cultures and in cells suspended in semisolid medium after introduction of a cloned human papillomavirus type 16 (hpv16) dna. hpv 16 dna stimulated both cell lines to grow beyond their saturation densities in monolayer cultures without any apparent morphological changes or tendency to pile up. these cells were also stimulated to grow in soft agar. since essentially all the ...19882824852
accumulation of rna homologous to human papillomavirus type 16 open reading frames in genital precancers.the accumulation of human papillomavirus type 16 (hpv-16)-specific rnas in tissue sections from biopsies of patients with genital precancers was studied by in situ hybridization with single-stranded 35s-labeled rna. these analyses revealed that the most abundant early-region rnas were derived from the e4 and e5 open reading frames (orfs). rnas homologous to the e6/e7 orfs were also detected, whereas rnas homologous to the intervening e1 orf were not. this suggests that the e4 and e5 mrnas are de ...19882824859
evaluation of methods for detecting human papillomavirus deoxyribonucleotide sequences in clinical specimens.specimens from 26 condylomatous lesions, 24 invasive cancer cells, and 33 cervices, without evidence of the diseases, were tested for the presence of human papillomavirus (hpv) types 6, 11, 16, and 18 by southern blot hybridization, in situ filter hybridization, or in situ tissue hybridization methods. a total of 89% (23 of 26) of the condylomatous lesions contained hpv dnas, as determined by one or more of the methods. the positive rates for the detection of hpv dna in condylomas by the differe ...19882830308
continuity of human papillomavirus (hpv) type between neoplastic precursors and invasive cervical carcinoma. an in situ hybridization study.infection by the human papillomaviruses (hpv) represents an important risk factor in squamous lesions of various sites. more recently, data suggest that the glandular components of some tumors may also contain human papillomaviruses. this association may implicate hpvs in the genesis of these lesions as well. we present a longitudinal in situ hybridization study of hpv expression within a single patient, showing viral mrna in squamous dysplasia, squamous and adenocarcinoma in situ, and in invasi ...19882830800
histological correlates of clinically occult human papillomavirus infection of the uterine cervix.occult infection of the uterine cervix by human papillomavirus (hpv) is assumed when viral dna sequences are detected from cervical swabs but no lesion is detectable and the papanicolaou smear is negative. in an attempt to identify what histological changes correlate with occult infections, dna was extracted from 200 cervical swabs taken from hysterectomy specimens. the dna was analyzed by southern blot hybridization for the presence of hpv sequences. eleven cases (5.5%) were positive. the entir ...19882830801
condylomata acuminata of the urinary bladder. natural history, viral typing, and dna content.three patients with condylomata acuminata of the urinary bladder are reported. two of the patients were immunosuppressed, and one had longstanding extensive condylomata acuminata of the external genitalia and adjacent areas. all lesions recurred at least once and were difficult to treat. the diagnosis was confirmed by in situ hybridization on archival material with human papillomavirus (hpv) dna probes under stringent conditions. in two of the patients, probes for hpv types 6 and 11 were positiv ...19882830802
histological and cytological evidence of viral infection and human papillomavirus type 16 dna sequences in cervical intraepithelial neoplasia and normal tissue in the west of scotland: evaluation of treatment policy.biopsy samples from 27 patients referred to a colposcopy clinic in glasgow for cervical abnormalities were assessed for the relations among colposcopic appearances, cytological and histological diagnosis, expression of papillomavirus antigen, and the presence of human papillomavirus (hpv) types 6, 11, 16, and 18 deoxyribonucleic acid (dna) sequences. specimens were from colposcopically abnormal areas of the transformation zone and from colposcopically apparently normal areas of the zone in the s ...19882830935
possible prognostic significance of human papillomavirus type in cervical cancer.while several different human papillomaviruses (hpv) have been associated with cancer of the cervix, it is yet to be determined if specific hpv types have clinical or prognostic significance. to address this question, 30 cases of invasive carcinoma (squamous carcinoma, adenosquamous carcinoma, and adenocarcinoma) with hpv dna sequences detectable in the tissue were analyzed. hpv type was determined by southern blot dna hybridization. clinical information was obtained by chart review, and all bio ...19882831120
sexual transmission of human papillomaviruses in heterosexual and male homosexual couples, studied by dna hybridisation.the prevalence of human papillomavirus (hpv) 6, 11, 16, and 18 in 36 heterosexual couples and seven male homosexual couples with genital warts was investigated for evidence of sexual transmission of genital hpv. the prevalence of virus type and number of copies of viral genome equivalents/cell in the lesions were assessed, and the factors influencing transmission analysed. our results show that hpv 6 and, to a lesser extent, hpv 11 were the types most readily transmitted, and that transmission a ...19882831137
isolation of a novel human papillomavirus (type 51) from a cervical condyloma.we cloned the dna from a novel human papillomavirus (hpv) present in a cervical condyloma. when dna from this isolate was hybridized at high stringency with hpv types 1 through 50 (hpv-1 through hpv-50), it showed weak homology with hpv-6 and -16 and stronger homology with hpv-26. a detailed restriction endonuclease map was prepared which showed marked differences from the maps for other hpvs that have been isolated from the female genital tract. reassociation kinetic analysis revealed that hpv- ...19882831406

does human papillomavirus cause cervical cancer? the state of the epidemiological evidence.the human papillomavirus has emerged over the past decade as the leading candidate to be the sexually transmitted aetiological factor in cervical cancer. although it appears that papillomavirus types 16 and 18 are associated with a higher risk of advanced cervical neoplasia, most of the evidence comes from studies which do not satisfy basic epidemiological requirements, and are therefore difficult to interpret. the most significant problems are the small sample size, potentially biased selection ...19882831924
psychosexual trauma of an abnormal cervical smear.the psychosexual sequelae of diagnosis and treatment of pre-invasive cervical atypia were assessed in three groups of women. the first group included 30 women referred to a colposcopy clinic with an abnormal cervical smear indicating cervical intraepithelial neoplasia (cin), the second comprised 50 women who were traced as sexual partners of men with penile human papillomavirus (hpv) infection; 26 of them had histologically proven cervical atypia and 24 had no such evidence. the third group incl ...19882831933
genital virus infection and cervical neoplasia.the reported association between genital infection by herpes simplex virus (hsv) type 2 and cervical neoplasia has been investigated at a molecular level. tissue culture of over 50 cervical cancers resulted in the development of several cell lines but none of these expressed hsv information. the permanent cell line, cx106, which was generated was found to contain multiple genome copies of human papillomavirus (hpv) type 16. southern blot analysis of nine cervical cancers showed an authentic 2.8 ...19882831934

large atypical polyps of the vagina during pregnancy with concomitant human papilloma virus infection.a 25-yr-old primigravid patient with large atypical fibroepithelial polyps of the vagina is presented. the tumors necessitated interruption of the pregnancy by cesarean section at 34 wks. after delivery the tumors were excised, and the patient has been symptom-free for 12 months. there was an intercurrent human papilloma virus (hpv) infection in the vaginal epithelium. the nature of rare atypical vaginal fibroepithelial polyps is discussed on the basis of the literature. these lesions are clinic ...19882828132
detection of human papilloma virus in paraffin-embedded tissue using the polymerase chain reaction.human papilloma virus (hpv) dna sequences have been detected in paraffin-embedded tissue using an enzymatic in vitro amplification technique known as the polymerase chain reaction. amplification of a hpv dna sequence before its detection with a cdna probe significantly increases the rapidity as well as the sensitivity of detection such that a single 5-10-micron thick paraffin-embedded tissue section can be analyzed within 24 h. the assay specifically detected hpv 16 or 18 without crossreactivity ...19882826637
physical state and biological activity of human papillomavirus genomes in precancerous lesions of the female genital tract.the dna of distinct human papillomaviruses (hpvs) is regularly detected in the majority of human cervical carcinomas. in contrast to benign hpv-induced genital lesions, where the viral genomes are exclusively present as episomes, in cervical carcinomas hpv type 16 (hpv16) dna was found to be integrated into the host dna. in order to determine the physical state and expression of hpv dna sequences at different stages of tumour development, we analysed a series of cervical lesions (mild, moderate ...19882826665
identification of the human papillomavirus e2 protein in genital tract tissues.a 27-kilodalton protein representing approximately 60% of the e2 open reading frame of human papillomavirus type 6 (hpv-6) was synthesized in a bacterial expression system. affinity-purified polyclonal antibody to this protein detected the probable e2 gene product as a 50-kilodalton protein in most condylomas by western blot (immunoblot) analysis. the e2-positive condylomas were associated with hpv-6, hpv-11, hpv-16, or unidentified hpvs.19882826817
human papillomavirus type 16 open reading frame e7 encodes a transforming gene for rat 3y1 cells.human papillomavirus type 16 (hpv 16) dna is capable of morphologically transforming rat 3y1 cells. the expression plasmids, constructed from the simian virus 40-based expression vector psv2-0 and specific dna fragments from the putative early region of the hpv 16 genome, were tested for their transforming capacity. among the various psv2 plasmids, only those containing the intact e7 coding region were found to produce foci of the transformed rat cells which could grow in a soft-agar medium. the ...19882826818
regression of oral hairy leukoplakia after orally administered acyclovir therapy.to define the role of epstein-barr virus (ebv) in the pathogenesis of oral hairy leukoplakia, 13 human immunodeficiency virus-seropositive men with clinical and histologic evidence of oral hairy leukoplakia were enrolled in an open-label trial of orally administered acyclovir therapy (3.2 g/d for 20 days). of six patients who received therapy, five exhibited clinical regression. once therapy was discontinued, recurrences occurred in all responders. among seven patients who refused therapy, no sp ...19882826830
colposcopy is superior to cytology for the detection of early genital human papillomavirus infection.of 2232 women with no cytologic evidence of intraepithelial neoplasia, 250 (11.2%) were positive for human papillomavirus deoxyribonucleic acid (dna) by filter in situ hybridization. in 150 of those human papillomavirus-positive patients, an adequate colposcopic examination of the cervix was possible; human papillomavirus infection was diagnosed in 104 women (70%). cervical cytology showed evidence of human papillomavirus infection in only 23 patients (15%). the following colposcopic features we ...19882827083
human papillomavirus types and localization in adenocarcinoma and adenosquamous carcinoma of the uterine cervix: a study by in situ dna hybridization.formalin-fixed, paraffin-embedded tissues from 108 cases of invasive carcinoma of the uterine cervix, consisting of 40 cases of adenocarcinoma, 44 cases of adenosquamous carcinoma, and, as a control, 24 cases of squamous cell carcinoma were examined for the presence of human papillomavirus (hpv) dna by in situ hybridization of high sensitivity using tritium-labeled hpv-2, hpv-6, hpv-16, and hpv-18 dna probes. this method detects five genome copies of homologous hpv dna per cell. hpv dna was dete ...19882827890
expression of cytokeratin polypeptides in human papillomavirus (hpv) lesions of the uterine cervix: 1. relationship to grade of cin and hpv type.a series of 74 punch biopsies, derived from 513 women prospectively followed for cervical human papillomavirus (hpv) infections (including hpv-ncin, hpv-cin i, hpv-cin ii, and hpv-cin iii lesions), and 43 control cases (consisting of normal epithelia, nonspecific cervicitis, and classical cin lesions) were analysed for expression of cytokeratin polypeptides using the abc technique and monoclonal antibodies sk 56-23 (wide-spectrum antibody), sk 60-61 (specific for keratins 8 and 18), and sk 2-27 ...19882450850
characterization of primary human keratinocytes transformed by human papillomavirus type 18.primary human epithelial cells were cotransfected with phpv-18 and psv2neo, and cell strains were generated by selecting in g418. one cell strain (fe-a), which exhibits an extended life span, is currently in its 30th passage. in comparison, control cultures can only be maintained up to the seventh passage. southern blot analysis revealed the presence of at least one intact, integrated viral genome in these cells. fe-a cells showed altered growth properties, characterized by a change in morpholog ...19882452896
cervical lesions in patients with malignant melanoma.koilocytes were found in the cervical epithelium in association with cervical intra-epithelial neoplasia in 8 out of 9 cases of malignant melanoma. this suggests that the cervical lesion in them was of viral origin. in 62 women with malignant melanoma but without cervical atypia there was also an excess of koilocytosis compared with controls with neither lesion. these findings point to the possibility that human papilloma virus infection may also be involved in the development of malignant melan ...19882453994
immunohistochemistry (s 100, kl 1) and human papillomavirus dna hybridization on morbus bowen and bowenoid papulosis.in this study 55 paraffin embedded samples defined as bowen's disease or bowenoid papulosis were investigated with antibodies against s 100 protein and keratins (kl 1). s 100-positive cells were quantified and related to defined section area of the epidermal compartment by computer-assisted image analysis. the density of s 100-positive cells was compared with normal skin and was particularly related to growth patterns and keratinization of the different lesions under study. s 100-positive dendri ...19882455378
condyloma acuminatum of the bladder in two autopsy cases.condyloma acuminatum is a very rare lesion occurring in the bladder. we report two cases of condyloma acuminatum of the bladder found at autopsy, one in a 96-year-old woman and the other in an 80-year-old man. both had papillary or polypoid tumorous lesions in the trigone and neck of the bladder. the lesions were composed of nodular or papillary growths of squamous epithelium. the epithelium exhibited koilocytosis and the nuclei showed immunohistochemical staining for human papillomavirus antige ...19882455958
characterization of normal human exocervical epithelial cells immortalized in vitro by papillomavirus types 16 and 18 dna.an in vitro system for studying the interaction between human papillomavirus (hpv) 16 and 18 recombinant dna and normal human exocervical epithelial cells is described. eight hpv-immortalized human exocervical epithelial cell lines were established; all the lines contained either integrated hpv16 or 18 sequences and expressed hpv mrnas. thus, integration and expression appear to be required for immortalization. immortalized cells (greater than 200 population doublings to date) divided rapidly (d ...19882456144
analysis of hpv-1 e4 gene expression using epitope-defined antibodies.six monoclonal antibodies (mabs) have been raised against the e4 proteins of hpv-1. five of these were found to recognize denaturation-resistant epitopes as determined by western blotting--and their binding sites were identified by determining their reactivity against a panel of bacterial e4--beta-galactosidase fusion proteins which contained progressive deletions at the c-terminal end of the e4 region. the five mabs were found to bind to four distinct sites. by using these epitope-defined mabs, ...19882456213
human papillomavirus: the untreated male reservoir.human papillomavirus infection currently is accepted as a major factor in the etiology of carcinoma of the cervix, vagina and vulva. while the nature of genital human papillomavirus infection in women is well documented, detailed knowledge of the disease in the male partners is lacking. therefore, a prospective study was done to define the disease in the genitals of heterosexual men and to formulate an appropriate plan of management. we studied 52 men during an 8-month period for evidence of gen ...19882456403
continuous cell lines with altered growth and differentiation properties originate after transfection of human keratinocytes with human papillomavirus type 16 dna.immortalization of human keratinocytes (hkc) by human papillomavirus type 16 (hpv16) is reproducible at a high frequency, is due directly to the presence of the viral sequences in the cells, and occurs independently from the genetic characteristics of the host cells. ten human keratinocyte strains, each derived from a different individual, were transfected with pmhpv16d and selected with g418. eight became established lines. two strains, which failed to grow shortly after successful g418 selecti ...19882457456
selective suppression of human papillomavirus transcription in non-tumorigenic cells by 5-azacytidine.the transcription of human papillomavirus type 18 (hpv 18) is selectively suppressed in non-tumorigenic hela x fibroblast or hela x keratinocyte cell hybrids by 5-azacytidine. in contrast, viral gene expression is not influenced by 5-azacytidine in both tumorigenic hybrid segregants and in the parental hela cells. the suppression mechanism seems to operate at the level of initiation of transcription since nuclear run-on experiments show the absence of elongated nascent viral rna, whereas the tra ...19882457495
comparison of the in vitro transforming activities of human papillomavirus types.the association of certain human papillomavirus (hpv) types with the majority of human cervical carcinomas suggests a role for the virus in the development of this type of cancer. in this paper, we have examined the transforming properties of several hpv types where the early region genes of the virus are under the control of a strong heterologous promoter and show that major differences exist between the hpv types in their ability to transform primary rat kidney epithelial cells in conjunction ...19882458921
oral hairy leukoplakia: a light microscopic and immunohistochemical study.we compared the light microscopic features and immunoperoxidase staining for human papillomavirus antigen of oral hairy leukoplakia (ohl) and flat condylomatous lesions of the cervix. our findings support the conclusion that ohl and flat condylomatous lesions of the cervix are not similar morphologically or etiologically. therefore the term koilocyte seems inappropriate to describe the swollen epithelial cells in ohl. the various diagnostic criteria for a diagnosis of ohl were reviewed. on the b ...19882459649
human papillomavirus type 16 alters human epithelial cell differentiation in vitro.human papillomavirus (hpv) types 16, 18, 31, and 33 have been implicated as etiologic agents of cervical and penile cancer. using a cell culture system for keratinocytes which allows stratification and production of differentiation-specific keratins, we have examined the effects of one of these viruses, hpv-16, on the differentiation capabilities of human epithelial cells. a plasmid containing the hpv-16 genome and a neomycin-selectable marker was transfected into primary human epidermal cells a ...19882459699
[the campaign against sexually transmissible diseases and endemic treponematoses].from the moment who was established in 1948, the control of venereal diseases was felt to deserve highest priority, together with activities to control malaria and tuberculosis. international action was needed in view of the high morbidity and mortality from venereal diseases, their serious human and social consequences, and the prevalence of congenital syphilis and other sexually transmitted diseases (gonorrhoea, chancroid, venereal lymphogranulomatosis, granuloma inguinale). who immediately se ...19882459857
quantitative keratinocyte assay detects two biological activities of human papillomavirus dna and identifies viral types associated with cervical carcinoma.keratinocytes electroporated with human papillomavirus (hpv) dna (hpv-6, 11, 16 and 18) exhibited an increased cellular proliferation which was quantitated as microcolony and macrocolony formation. however, only macrocolonies induced by hpv-16 or hpv-18 dna (the two viral types most commonly found in human cervical carcinomas) gave rise to proliferating, poorly-stratified colonies when grown in the presence of serum and calcium. hydrocortisone increased the frequency of these differentiation-res ...19882460337
human papillomavirus dna in normal, metaplastic, preneoplastic and neoplastic epithelia of the cervix uteri.colposcopically directed cervical punch biopsies from 362 patients were screened by southern blot hybridization for the presence of dna of human papillomavirus (hpv) 6, 10, 11, 16, 18, 31 and 33. the biopsies represented original squamous epithelium, epithelium of metaplastic origin, different stages of cervical intraepithelial neoplasia (cin) and invasive carcinomas. hpv6/11, 16, 18 and 31 were detected in 2.9% to 13.7% of histologically normal epithelia. hpv6/11 prevailed in cin i. hpv16 was c ...19882826346
characterization of a new human papillomavirus (hpv 41) from disseminated warts and detection of its dna in some skin carcinomas.a new human papillomavirus type (hpv 41), distantly related to known hpv prototypes, was isolated from a patient with disseminated facial, peri-anal and foot warts (epidermodysplasia verruciformis was not diagnosed). the viral dna was molecularly cloned in 2 bamh1 restriction fragments with sizes of 6.5 kb and 0.98 kb, respectively. the classification of this cloned dna as a new type is based on the degree of cross-hybridization with 40 hpv types under conditions of varying stringency. a total o ...19882826347
analysis of human papillomavirus sequences in cell lines recently derived from cervical cancers.the dna and rna from four cell lines recently derived from cervical carcinomas (hx151c, hx155c, hx156c, and hx160c) were analyzed for the presence of human papillomavirus dna. each contained hpv-16 dna in a multicopy integrated form of varying complexity. each also expressed rna transcripts of similar sizes to caski cell transcripts. the splice acceptor position within the e6 coding region of the cell line hx156c was identical to caski, siha, and hela cells as well as a cell line derived from mo ...19882825972
prevalence of human papillomavirus in inverted nasal papillomas.human papillomaviruses (hpvs) have been associated with both benign and malignant neoplasms of the head and neck. to determine the prevalence and types of hpvs in this neoplasm, we examined fixed tissue from 21 patients by in situ hybridization. human papillomavirus types 6b and 11 probes were used, and hybridization was positive to both types in lesions from 16 (76%) of 21 patients. hybridization to the hpv-11 probe resulted in the most intense nuclear staining throughout the epithelium, probab ...19882825730
persistence and expression of human papillomavirus during interferon therapy.alpha interferon did not prevent the persistence or expression of human papillomavirus (hpv) types 6 or 11 in respiratory tract papillomas. seventeen patients receiving interferon therapy for a minimum of six months and a maximum of 39 months still had one to ten copies per cell genome of hpv dna in their laryngeal tissues, seen by southern blot hybridization. in papillomas that recurred during treatment, hpv rna could be detected by in situ hybridization, and capsid protein could be detected by ...19882825731
penile studies and heterosexual partners. peniscopy, cytology, histology, and immunocytochemistry.the male partners of 20 women with human papilloma virus (hpv) infection (subtypes 6, 11, 16, and 18) were studied. these men were unsuspecting and allowed investigation "for scientific reasons" in the context of the abnormal findings in their female partners. peniscopy (study of the penis with a colposcope) was abnormal in 17 cases. in the cytologic-brush preparations of the urethra, hyperkeratosis (visualized with the modified papanicolaou technique) occurred in all cases, but koilocytosis in ...19882450635
epidermal langerhans cells, dermal dendritic cells, and keratinocytes in viral lesions of skin and mucous membranes: an immunohistochemical study.we wanted to evaluate the eventual expression of viral antigens and mhc class ii products by keratinocytes as well as the alterations of epidermal langerhans cells and dermal dendritic cells in viral lesions of skin and mucous membranes. therefore we investigated 68 biopsy specimens of protracted viral lesions, such as warts, condylomas, and mollusca contagiosa, and of rapidly resolving viral lesions such as herpes simplex virus infection. for this we used immunohistochemical staining techniques ...19882466441
