Detection of Helicobacter pylori gene expression in human gastric mucosa.
Mucosal and systemic immunologic recognition of cagA by Helicobacter pylori-infected individuals is associated with peptic ulcer disease; however, in the laboratory, expression of cagA is subject to artificial conditions which may not accurately reflect the conditions in host tissues. Gastric antral and body biopsy specimens and serum for anti-H. pylori immunoglobulin G serology were obtained f...
متن کاملChemokines in the gastric mucosa in Helicobacter pylori infection.
BACKGROUND Although chemokines have been suggested to play an important role in Helicobacter pylori associated gastritis, few studies have investigated the role of chemokines other than interleukin 8 (IL-8) in gastric mucosa. AIMS To investigate the expression and production patterns of various chemokines using gastric biopsy specimens. METHODS In 192 patients, expression patterns of C-X-C ...
متن کاملHelicobacter pylori in dental plaque and gastric mucosa: correlation revisited.
Helicobacter pylori (H. pylori) related gastric infection is highly prevalent in developing countries. Prevalence of bacterium in dental plaque from these regions is also reported to be high, but association between simultaneous colonization of H. pylori in both these sites has not been established yet. Aim of this paper is to review possible association between simultaneous oral and gastric H....
متن کاملHelicobacter pylori eradication increases telomere length in gastric mucosa.
BACKGROUND/AIMS Our purpose in this study was to analyze telomere length and telomerase activity before and after eradication treatment in gastric mucosa in patients positive for H. pylori. METHODOLOGY There were two groups: a control group (n=17) and a study group (n=21). For H. pylori eradication, the patients were administrated proton pump inhibitor (PPI) + clarithromycin + amoxicillin or ...
متن کاملHELICOBACTER PYLORI Promoter methylation of E-cadherin gene in gastric mucosa associated with Helicobacter pylori infection and in gastric cancer
Background: E-cadherin is an adhesion molecule involved in tumour invasion/metastasis. Silencing of E-cadherin by promoter CpG methylation has been shown in both familial and sporadic gastric cancers. Helicobacter pylori is a class I carcinogen in gastric cancer. Aims: This study was undertaken to investigate the association between methylation of E-cadherin and H pylori in gastric mucosa from ...
