Carcinoma de células escamosas oral: relevância do Papiloma vírus humano (HPV) ...
Lima, Marcos Antonio Pereira deThe oral cancer represents a serious world public health problem. The oral squamous cell carcinomas (OSCC) account for up to 94% of the tumors of this anatomic site. The molecular mechanisms involved in the genesis and progression are still not well elucidated. Some evidences have suggested the involvement of viruses in this process. Also, these tumors still lack of reliable markers to determine the aggressiven...
Association between human papillomavirus (HPV) and the oral squamous cell carci...
Lima, Marcos Antonio Pereira de; Silva, Cláudio Gleidiston Lima da; Rabenhorst, Silvia Helena BaremThe human papillomavirus (HPV) is an epitheliotropic agent whose high-risk genotypes have a well-established link with the development of cervical cancer. Although the relation of HPV to the oral squamous cell carcinoma (OSCC) has been studied since the beginning of the 1980s, its role in the oral carcinogenesis and the probable underlying molecular mechanisms are still not fully elucidated. We performed a syst...
Papel das proteínas precoces do papilomavírus humano na carcinogênese
Lima, Marcos Antonio Pereira de; Silva, Cláudio Gleidiston Lima da; Rabenhorst, Silvia Helena BaremIntrodução: o Papilomavírus Humano (HPV) é um agente epiteliotrópico que apresenta mais de 100 genótipos. d estes, alguns são considerados de alto risco devido ao potencial para induzir o surgimento de lesões malignas, como o carcinoma cervical, cujo percentual de associação com o referido vírus é de aproximadamente 90%. n as células infectadas, duas proteínas virais desempenham papel fundamental na tumorigênes...

The relationship between Helicobacter pylori genes cag E and vir B11 and gastri...
Lima, Valeska Portela; Lima, Marcos Antonio Pereira de; Ferreira, Márcia Valéria Pitombeira; Barros, Marcos Aurélio Pessoaackground: The association between Helicobacter pylori gene diversity and gastric cancer has been poorly reported, although it is one of the important ways to explain the gastric pathogenesis. The aim of this study was to investigate the frequency of cag E and vir B11 genes in H. pylori isolated from patients with gastric cancer and to analyze the histology profiles. Materials and methods: The presence of H. py...
Helicobacter pylori (CagA) and Epstein Barr virus infection in gastric carcinom...
Lima, Valeska Portela; Lima, Marcos Antonio Pereira de; André, Ângela Rosa; Ferreira, Márcia Valéria Pitombeira; Barros, Marcos Aurélio PessoaAIM: To investigate the interrelationship between H pylori and Epstein-Barr virus (EBV) infection in the gastric carcinogenesis having in focus the p53 mutation and the c-Myc, Bcl-2 and Bax expression. METHODS: seventy-one gastric carcinoma tissues were assessed by polymerase chain reaction (PCR) for H pylori and in situ hybridization for EBV. c-Myc, Bcl-2 and Bax expression were detected by immunohistochemistr...
Estudo do vírus Epstein-Barr (EBV) em adenocarcinoma gástrico : freqüência, ass...
Lima, Marcos Antonio Pereira deThe Epstein-Barr virus (EBV) has been related to the tumorigenesis of the gastric carcinomas, varying from 1.3-19.3% according to the studied population. Several studies have demonstrated strong evidences of its relation in this process, such as the monoclonality of the viral genome and its the presence in almost all tumor cells. However, most of the mechanisms used by the virus to control this process are stil...
