typing of human papillomavirus in women with cervical lesions: prevalence and distribution of different genotypes.human papillomavirus (hpv) are distributed widely and persistent infection with high-risk (hr) hpv is recognized as a necessary cause of cervical cancer. the aim of this study was to evaluate the distribution of different hr-hpv genotypes in 199 women with cervical pre-invasive lesions undergoing conservative treatment. a linear array hpv genotyping test was used to identify individual hpv genotypes in cervical samples. it was observed that the most prevalent hpv genotypes were hpv 16 (52.6%), h ...200919107962
genomic diversity of human papillomavirus (hpv) genotype 38.human papillomavirus (hpv) genotype hpv 38 is a hpv genotype associated with skin cancer and is classified taxonomically in the beta-pv genus-species 2. at least six genomic variants of hpv 38, including prototype isolate and its subtype fa125, have been characterized so far. in order to investigate further the genomic diversity of hpv 38, a total of 39 hpv 38 positive samples obtained from hairs plucked from pubic, scrotal, perianal or eyebrow regions from 31 immunocompetent healthy male indivi ...200919107968
tax1bp1 interacts with papillomavirus e2 and regulates e2-dependent transcription and stability.the papillomavirus e2 proteins regulate viral replication, gene transcription, and genome maintenance by interacting with other viral and host proteins. from a yeast two-hybrid screen, we identified the cellular protein tax1bp1 as a novel binding partner of human papillomavirus type 18 (hpv18) e2. tax1bp1 also interacts with the hpv16 and bovine papillomavirus type 1 (bpv1) e2 proteins, with the c-terminal region of tax1bp1 interacting with the n-terminal transactivation domain of bpv1 e2. tax1b ...200919109394
sequence variation of human papillomavirus type 16 and measurement of viral integration by quantitative pcr.given that the integration of human papillomavirus type 16 (hpv16) into the host genome occurs preferentially with the disruption of the e2 gene, a ratio of e2 to e7 gene copies is often used as a marker for integration. it is largely undetermined, however, whether ratio estimates are affected by hpv intratypic variations. we assembled four plasmid constructs, each containing a dna fragment from an hpv16 european, asian-american, african-1, or african-2 variant. these constructs and nine cervica ...200919116350
antibody response for l1, e6, e7 hpv 16, and hpv 18 antigens in tunisian women with cervical cancer.results obtained in the present work indicated that the luminex assay is more sensitive than elisa. the reactivity to the early antigens e6 and e7 was 37% versus 42% for hpv 16 and 21% versus 20% for hpv 18 among cervical cancer cases using elisa. however, these ratios were 44% and 61%, respectively, for e6 and e7 hpv 16 versus 28% and 21% for e6 and e7 hpv 18 when using the luminex technique. data also indicated that hpv 16 and hpv 18 showed distinct profiles for the different antigens tested. ...200919117204

single nucleotide polymorphism array analysis defines a specific genetic fingerprint for well-differentiated cutaneous sccs.cutaneous squamous cell carcinomas (csccs) are the second most frequent cancers in fair-skinned populations; yet, because of their genetic heterogeneity, the key molecular events in cscc tumorigenesis remain poorly defined. we have used single nucleotide polymorphism microarray analysis to examine genome-wide allelic imbalance in 60 csccs using paired non-tumor samples. the most frequent recurrent aberrations were loss of heterozygosity at 3p and 9p, observed in 39 (65%) and 45 (75%) tumors, res ...200919131950
expression of human papilloma virus type 16 e5 protein in amelanotic melanoma cells regulates endo-cellular ph and restores tyrosinase activity.melanin synthesis, the elective trait of melanocytes, is regulated by tyrosinase activity. in tyrosinase-positive amelanotic melanomas this rate limiting enzyme is inactive because of acidic endo-melanosomal ph. the e5 oncogene of the human papillomavirus type 16 is a small transmembrane protein with a weak transforming activity and a role during the early steps of viral infections. e5 has been shown to interact with 16 kda subunit c of the trans-membrane vacuolar atpase proton pump ultimately r ...200919133143
palliative aspects of recurrent respiratory papillomatosis.recurrent respiratory papillomatosis (rrp) is a chronic, frequently debilitating, and potentially life-threatening disease. therapy for rrp has evolved from simply inserting a tracheotomy to provide an airway and plucking out papillomata with cup forceps to provide some degree of voice to the present-day far more sophisticated approaches, along with preventative measures that may someday offer the potential dramatically to decrease disease prevalence. family dynamics and support and intentional ...200919134490
enhancement of dendritic cell-based vaccine potency by anti-apoptotic sirnas targeting key pro-apoptotic proteins in cytotoxic cd8(+) t cell-mediated cell death.dendritic cells (dcs) have become an important measure for the treatment of malignancies. current dc preparations, however, generate short-lived dcs because they are subject to cell death from various apoptotic pressures. antigen-specific cd8(+) cytotoxic t lymphocytes (ctls) is one of the main obstacles to limit the dc-mediated immune priming since ctls can recognize the target antigen expressing dcs as target cells and kill the dcs. ctls secret perforin and serine protease granzymes during ctl ...200919135479
asymmetric gp5+/6+ pcr and hybridization with fluorescence polarization assay of 15 human papillomavirus genotypes in clinical samples.the detection of a broad spectrum of hpv genotypes has not been used widely in cervical cancer screening due to technical difficulties and high costs.200919144564
molecular hpv typing as a diagnostic tool to discriminate primary from metastatic squamous cell carcinoma of the lung.in this study, typing of human papilloma virus (hpv) was performed in squamous cell carcinomas of the lung (n=26) as well as putative primaries of head and neck (n=21) and female genital tract (n=5) of the same patients, to test whether additional information to discriminate lung primaries from metastases can be gained by a direct comparison of the hpv status in both tumors. in 3 (14.2%) patients with head and neck as well as lung squamous cell carcinoma, an identical hpv subtype could be detect ...200919145203

chromosomal signatures of a subset of high-grade premalignant cervical lesions closely resemble invasive carcinomas.cervical cancer develops from precancerous high-grade cervical intraepithelial neoplasia (cin) harboring a transforming infection with high-risk human papillomavirus, which is characterized by p16(ink4a) overexpression. once such a lesion has developed, progression toward an invasive squamous cell carcinoma (scc) may take one or more decades, underlining the heterogeneity of these lesions in terms of duration of existence and progression risk. we performed array-based comparative genomic hybridi ...200919147580
anticancer effects on tacc3 by treatment of paclitaxel in hpv-18 positive cervical carcinoma cells.previously, we used proteome analysis to identify transforming acidic coiled coil (tacc) 3 as a protein that is down-regulated upon paclitaxel treatment in cervical cancer cells. tacc3 mrna and protein levels decreased after paclitaxel treatment in a time- and dose-dependent manner, and the transactivation of tacc3 promoter was dramatically diminished by paclitaxel. importantly, paclitaxel treatment and knockdown of tacc3 by sirna led to a synergistic enhancement of significant g2/m phase arrest ...200919148534
interaction between human papillomavirus type 5 e2 and polo-like kinase 1.the e2 protein of the papillomavirus plays an essential role in the viral life cycle. through a yeast two-hybrid screening, human polo-like kinase 1 was found to interact with human papillomavirus type 5 e2. further characterization identified that the domains responsible for the interaction are the transactivation domain of hpv-5 e2 and the sequence between the kinase and the polo box domains of plk1. in vivo, plk1 and hpv-5 e2 are colocalized at the nuclear speckles. in the skin epithelium not ...200919152411
high-risk hpv types in lesions of the uterine cervix of female commercial sex workers in the philippines.in order to prevent cervical cancer, vaccines against human papilloma virus types 16 (hpv-16) and 18 (hpv-18) have been implemented worldwide. however, the hpv types that cause cancer can differ according to geographical area and ethnicity. in this new era of the hpv vaccine, it is important to elucidate the prevalent hpv types in each area. therefore, the prevalence of hpv infection and cervical abnormalities among 369 female commercial sex workers in the philippines were examined. hpv l1 gene ...200919152419
gene expression patterns induced by hpv-16 l1 virus-like particles in leukocytes from vaccine recipients.human papillomavirus (hpv) virus-like particle (vlp) vaccines were recently licensed. although neutralizing ab titers are thought to be the main effectors of protection against infection, early predictors of long-term efficacy are not yet defined and a comprehensive understanding of innate and adaptive immune responses to vaccination is still lacking. here, microarrays were used to compare the gene expression signature in hpv-16 l1 vlp-stimulated pbmcs from 17 vaccine and 4 placebo recipients be ...200919155521
a strained dna binding helix is conserved for site recognition, folding nucleation, and conformational modulation.nucleic acid recognition is often mediated by alpha-helices or disordered regions that fold into alpha-helix on binding. a peptide bearing the dna recognition helix of hpv16 e2 displays type ii polyproline (pii) structure as judged by ph, temperature, and solvent effects on the cd spectra. nmr experiments indicate that the canonical alpha-helix is stabilized at the n-terminus, while the pii forms at the c-terminus half of the peptide. re-examination of the dihedral angles of the dna binding heli ...200919156829
characterization of immortalized human epidermolysis bullosa simplex (krt5) cell lines: trimethylamine n-oxide protects the keratin cytoskeleton against disruptive stress condition.epidermolysis bullosa simplex (ebs) is an autosomal inherited mechano-bullous disease, characterized by intraepidermal blistering and skin fragility caused by mutations in the keratin (krt) 5 or 14 genes. despite a vast knowledge about the intermediate filament pathology in this disease, the progress in therapy has been slow. animal models and well-characterized continuous cell culture models of ebs are needed prior to clinical testing.200919157792
a type-specific study of human papillomavirus prevalence in cervicovaginal samples in three different spanish regions.human papillomavirus (hpv) is the most frequent sexually transmitted viral infection. it is necessary to know hpv genotype distribution to identify how many women will be protected by hpv vaccines. during a period of 18 months, we have analyzed 2362 hpv positive reporting data from a secondary demand screening program in three regions in spain (cantabria, leon and burgos). the study has been conducted using polymerase chain reaction and tube array hybridization covering the 35 hpv genotypes desc ...200919161533
induction of focal epithelial hyperplasia in tongue of young bk6-e6/e7 hpv16 transgenic mice.squamous cell carcinoma (scc) of the oral cavity is one of the most common neoplasms in the world. during the past 2 decades, the role of high-risk human papilloma virus (hr-hpv) has been studied and the data supporting hpv as a one of the causative agents in the development and progression of a sub-set of head and neck squamous cell carcinomas (hnscc) has accumulated. in order to investigate the role of hr-hpv oncogene expression in early epithelial alterations in vivo, we produced transgenic m ...200919165615
the bcl-xl inhibitor of apoptosis is preferentially expressed in cutaneous squamous cell carcinoma compared with that in keratoacanthoma.keratoacanthoma (ka) is difficult to histologically distinguish from squamous cell carcinoma (scc). therefore, although ka is a benign self-resolving skin lesion, ka is commonly treated as scc. biomarkers to distinguish ka and scc would thus be desirable. in search for specific markers, paraffin-embedded tissue samples from 25 scc and 64 ka were arranged in a tissue microarray (tma) and stained for immunologic cell-markers cd3, cd20 and cd68 as well as for proteins considered of relevance in tum ...200919165861
triage of women with equivocal or low-grade cervical cytology results: a meta-analysis of the hpv test positivity rate.consistent evidence underlines the utility of human papillomavirus (hpv) dna testing in the management of women with equivocal cervical cytological abnormalities, but not in case of low-grade lesions. we performed a meta-analysis including studies where the high-risk probe of the hybrid capture-ii is used to triage these two cytological categories. the triage test-positivity rate reflects the colposcopy referral workload.data were pooled on the hpv test positivity rate in women with atypical squ ...200919166485

immortalization of normal human gingival keratinocytes and cytological and cytogenetic characterization of the cells.most in vitro studies of oral carcinogenesis in human cells are carried out with oral keratinocytes immortalized by human papillomavirus type 16 dna. however, because various etiological factors for oral cancer are known, it is important to establish new human keratinocyte cell lines useful for studying the mechanism of oral carcinogenesis. normal human gingival keratinocytes in secondary cultures grown in serum-free medium were either transfected with origin (-) sv40 dna or sequentially transfe ...200919184294
ensembled support vector machines for human papillomavirus risk type prediction from protein secondary structures.infection by the human papillomavirus (hpv) is regarded as the major risk factor in the development of cervical cancer. detection of high-risk hpv is important for understanding its oncogenic mechanisms and for developing novel clinical tools for its diagnosis, treatment, and prevention. several methods are available to predict the risk types for hpv protein sequences. nevertheless, no tools can achieve a universally good performance for all domains, including hpv and nor do they provide confide ...200919185855
genetic variants in tap are associated with high-grade cervical neoplasia.the transporter associated with antigen processing (tap) is essential in assembling mhc-i proteins. human papillomavirus (hpv) evades immune recognition by decreasing class i mhc cell surface expression through down-regulation of tap1 levels. consistent with heterogeneity in mhc expression is the individual variability in clearing detectable hpv infections. genetic polymorphisms in tap genes may affect protein structure, function, and the ability to clear hpv infection.200919188174
