Última Non-detection of Epstein-Barr virus and human papillomavirus in a region of high gastric cancer risk indicates a lack of a role for these viruses in gastric carcinomas Genet. Mol. Biol. Yuan,Xiao-yan; Wang,Ming-yi; Wang,Xiao-yan; Chang,Ai-ying; Li,Jie. Gastric mucosa tissue was collected from patients with gastroduodenal diseases in a region of norrteastern China showing a high risk of gastric cancer incidence. The presence of EBV and HPV were assayed to investigate the relationship between gastric carcinomas and virus infection. Neither EBV nor HPV DNA was detected in tissue from the patients. The role of EBV and HPV in gastric cancer is not well understood and still needs to be clarified.

Abstract The severity of Helicobacter pylori-related disease is correlated with the presence and integrity of a cag pathogenicity island (cagPAI). cagPAI genotype may have a modifying effect on the pathogenic potential of the infecting strain. After analyzing the sequences of cagPAI genes, some strains with the East Asian-type cagPAI genes were selected for further analysis to examine the association between the diversity of the cagPAI genes and the virulence of H. pylori. The results showed that gastric mucosal inflammatory cell infiltration was significantly higher in patients with East Asian-type cagPAI genes H. pylori strain compared with mosaicism cagPAI genes H. pylori strain (p < 0.05). H. pylori strains with the East Asian-type cagPAI genes were... Tipo: Info:eu-repo/semantics/article Palavras-chave: Helicobacter pylori; CagPAI; Virulence; IL-8.
