Apoptosis in Gastric Epithelial Cells Is Induced byHelicobacter pyloriand Accompanied by Increased Expression of BAK

Abstract excerpt

Carriage of the bacterium H. pylori in the human stomach is associated with evidence of increased epithelial cell apoptosis. This may be of significance in the etiology of gastritis, peptic ulcers, and neoplasia. The ability of H. pylori to directly induce epithelial apoptosis was examined in vitro by fluorescence and electron microscopy, flow cytometry, and DNA fragmentation ELISA. The induction of apoptosis by...
