Helicobacter pylori increases proliferation of gastric epithelial cells.

The direct and indirect effects of helicobacter pylori on cell kinetics of gastric epithelial cell line AGS were investigated by flow cytometric analysis of Ki-67 positive cells and by MTT assay. Flow cytometric analysis of Ki-67 positivity permits detection of cells that are in S-phase, whereas the MTT assay is a colometric measure of the number of viable cells. In the absence of added stimula...

Macrophage migration inhibitory factor stimulated by Helicobacter pylori increases proliferation of gastric epithelial cells.

AIM Helicobacter pylori (H pylori) is associated with increased gastric inflammatory and epithelial expression of macrophage migration inhibitory factor (MIF) and gastric epithelial cell proliferation. This study aimed at determining whether H pylori directly stimulates release of MIF in monocytes, whether the cag pathogenicity island (PAI) is involved for this function, and whether MIF stimula...

Decreased gastric proliferation of foveolar epithelial cells after the eradication of Helicobacter pylori.

Increased epithelial cell proliferation is associated with an increased risk of gastric carcinoma. Helicobacter pylori infection is an established risk factor for gastric cancer and the organism has recently been classified as a group I carcinogen by an IARC working group. In this study, we describe differences in gastric epithelial cell proliferation between a H. pylori eradicated group (n = 2...

Helicobacter pylori increases proteasome-mediated degradation of p27(kip1) in gastric epithelial cells.

Helicobacter pylori infection is associated with increased gastric epithelial cell turnover and is a risk factor for noncardia gastric cancer. H. pylori reduces the expression of p27 protein, a cyclin-dependent kinase inhibitor of the G(1) to S-phase cell cycle transition and gastric tumor suppressor gene. Although cell cycle dysregulation associated with decreased p27 may contribute to gastric...
