(oipA) of Helicobacter pylori
MICROBIOLOGY. For the article ‘‘A Mr 34,000 proinflammatory outer membrane protein (oipA) of Helicobacter pylori’’ by Yoshio Yamaoka, Dong H. Kwon, and David Y. Graham, which appeared in number 13, June, 20, 2000, of Proc. Natl. Acad. Sci. USA (97, 7533–7538), the authors note the following correction. The sequence of the HP0638 gene was incorrect as published. The sequence published was 59-GCT...
متن کاملCloning and Sequence Analysis of Gene Encoding OipA from Iranian Clinical Helicobacter pylori
Background: Outer inflammatory protein A (OipA) is one of the important adhesins of H. pylori and a valuable candidate for vaccine development. Its gene is under "on-off" switch status which correlates with OipA protein expression. Objectives: We aimed to obtain a recombinant OipA clone (with "on" status) from an Iranian clinical isolate. Materials and Methods: A clinical H. pylori-isolate demo...
متن کاملHelicobacter pylori HopH (OipA) and bacterial pathogenicity: genetic and functional genomic analysis of hopH gene polymorphisms.
BACKGROUND Expression of the Helicobacter pylori outer membrane protein HopH is regulated by phase variation within a CT dinucleotide repeat motif of the hopH gene. METHODS To investigate the importance of HopH for bacterial pathogenicity, we performed a detailed functional genomic and population-based genetic characterization of this contingency locus. RESULTS Sequencing of hopH in H. pylo...
متن کاملRelevance of Helicobacter pylori dupA and OipA genotypes and development of gastric disease
Helicobacter pylori infection is now accepted as the major cause of severe gastritis-associated diseases, including peptic ulcer and gastric cancer. In the current study, we decided to determine the dupA and OipA genotypes in H. pylori strains isolated from patients with gastrointestinal disorders and to evaluate whether these genes are associated with the severity of the gastroduodenal disease...
متن کاملDesign, cloning and expression assay of oipA gene in a bicistronic vector harboring mice IL-18 gene: potential implications for Helicobacter pylori vaccine investigations
Introduction: Helicobacter pylori (H. pylori) infection has remained as a global health problem. Animal studies demonstrated the role of H. pylori oipA gene in the development of gastric cancer. The aim of this study was the cloning and expression of Helicobacter pylori oipA gene in a bicistronic vector harboring mice IL-18 gene. Materials and methods: The target gene encoding oipA was amp...
