1. Alterations in the expression and activity of extracellular matrix components in HPV-associated infections and diseases
Infection with human papillomaviruses is associated with a series of benign and malignant hyperproliferative diseases that impose a heavy burden on human populations. A subgroup of mucosal human papillomavirus types are associated with the majority of cervical cancers and a relevant fraction of vulvar, vaginal, anal, penile and head and neck carcinomas. Huma

2. Epidemiology and biology of cutaneous human papillomavirus
Cutaneous human papillomaviruses (HPVs) include β- and γ-HPVs, in addition to a small fraction of α-HPVs. β-HPVs were first isolated from patients with the rare genetic disorder Epidermodysplasia verruciformis, and they are associated with the development of nonmelanoma skin cancer at sun-exposed skin sites in these individuals. Organ transplant recipien

3. Papillomaviruses: a systematic review
Abstract In the last decades, a group of viruses has received great attention due to its relationship with cancer development and its wide distribution throughout the vertebrates: the papillomaviruses. In this article, we aim to review some of the most relevant reports concerning the use of bovines as an experimental model for studies related to papillomavir

4. Epidemiology of oral HPV in the oral mucosa in women without signs of oral disease from Yucatan, Mexico
High-risk human papillomaviruses (HR-HPV) are considered necessary for the development of cervical cancer. Furthermore, there is no doubt that some types of oral squamous cell carcinoma are associated with HR-HPV. The epidemiology of oral HPV infections in healthy subjects remains unclear due to a lack of knowledge. The objective of this study was to investi

5. Enhanced anti-tumor effect of a gene gun-delivered DNA vaccine encoding the human papillomavirus type 16 oncoproteins genetically fused to the herpes simplex virus glycoprotein D
Anti-cancer DNA vaccines have attracted growing interest as a simple and non-invasive method for both the treatment and prevention of tumors induced by human papillomaviruses. Nonetheless, the low immunogenicity of parenterally administered vaccines, particularly regarding the activation of cytotoxic CD8+ T cell responses, suggests that further improvements

6. Genotipagem de HPV proveniente de mulheres soropositivas e soronegativas para HIV atendidas no Centro de Referência em DST/AIDS em Vitória - ES
Os papilomavírus humanos (HPV) são vírus epiteliotrópicos que infectam tecido cutâneo ou mucoso e estão relacionados com desenvolvimento de lesões que, no trato genital, variam de verrugas ao câncer cervical invasivo. Estas lesões são causadas por diferentes tipos de HPV, que são classificados em baixo e alto risco conforme sua associação com c�

7. Phylogenetic position of an uncharacterized Brazilian strain of bovine papillomavirus in the genus Xipapillomavirus based on sequencing of the L1 open reading frame
The use of PCR assays with degenerate primers has suggested the existence of numerous as yet uncharacterized bovine papillomaviruses (BPV). Despite the endemic nature of BPV infections, the identification of BPV types in Brazilian cattle is still only sporadic. However, in a recent analysis of a partial segment of the L1 gene, we observed notable diversity a

8. IdentificaÃÃo e avaliaÃÃo da presenÃa de PapilomavÃrus bovino (BPV) em sangue de bovinos e cultura de linfÃcitos em uma fazenda leiteira do estado de Pernambuco
Bovine papillomaviruses (BPVs), family Papillomaviridae, act as causal agent of warts, bladder and digestive tract cancers, causing significant losses to the cattle economy. Ten types of BPVs have been well characterized (BPV-1-10). This study has as main objective to evaluate sequences of BPV genomes in blood samples collected in a dairy farm in Pernambuco

9. AvaliaÃÃo da presenÃa de PapilomavÃrus bovino em sÃmen de touros (Bos taurus)
Papillomaviruses (PV) are viruses that contain double strand DNA and can infect the squamous epithellium of the skin and mucosa. There are 10 different types of BPV (BPV-1 to 10) and they can cause serious diseases in dairy herds or cutting, creating great economic losses to farmers in Brazil and other countries. The presence of BPV has been detected in repr

10. Identificação e estudo da diversidade do papilomavírus associado a lesões cutâneas em bovinos
Papillomaviruses (PV) has a worldwide distribution and is recognized as an etiologic agent associated with several benign and malignant epithelia lesions in human and animals. The Papillomaviridae family is a highly heterogeneous group of viruses, which has 18 genera, and likely occurs in most mammals and birds. The PV genome is circular double-stranded DNA

Papillomaviruses are a wide viruses family associated to epiteliotropic lesions and affecting also mucous tissues, causing benign tumors that can suffer malignization. The bovine papilomatosis is an economicaly important desease, since undervaluate cattle to be selled out. Although epidemiological data are unavailable, based on local farmers the incidence of

12. Caracterização molecular do gene L1 de um provável novo tipo de papilomavírus bovino identificado no Brasil
Papillomaviruses (PVs) comprise a highly diverse group of non-enveloped oncovirus classified in Papillomaviridae family, whose genome consists of a circular double-stranded DNA molecule. Depending on nucleotide identity presented in structural protein L1, 10 types of bovine papillomavirus (BPV) are described in cattle, being each of them located in genera De
