The release of LPS by bacteria stimulates both immune and specific epithelial cell types to release inflammatory mediators. It is known that LPS induces the release of IL-8 by intestinal mucosal cells. Because it is now emerging that bacteria may induce alteration of epigenetic patterns in host cells, we have investigated whether LPS-induced IL-8 activation(More)
COX-2 expression is altered in gastrointestinal diseases. Helicobacter pylori (Hp) infection may have a critical role in COX-2 disregulation. We undertook this study to investigate possible chromatin and DNA methylation changes occurring early during COX-2 gene activation as a direct consequence of Hp-gastric cells interaction. We show that Hp infection is(More)
Inducible nitric oxide synthase (iNOS) expression is altered in gastrointestinal diseases. Helicobacter pylori (Hp) infection may have a critical role in iNOS disregulation. We undertook this study to investigate possible chromatin changes occurring early during iNOS gene activation as a direct consequence of Hp–gastric cells interaction. We show that Hp(More)
