Tummy troubles -- gastrin key in bacterial-induced stomach cancer
Date:6/23/2009

s a central role in the safety network for the protection from mucosal damages caused by gastric acid secretion induced by gastrin itself, and thus either too much or too little gastrin can predispose to carcinogenesis. Therefore, clinicians in the future may need to be more circumspect when prescribing with acid suppressive drugs, such as proton-pump inhibitors, for a long-term use in patients infected with Helicobacter pylori." In future studies, Dr. Wang and colleagues plan to study "host factors other than gastrin [that] are also important for Helicobacter-associated gastric carcinogenesis. These include specific cytokines and chemokines induced by Helicobacter infection, and modulated by gastrin, that link inflammation and cancer. In addition, they plan to study the role of other non-Helicobacter bacteria that colonize the stomach when acid secretion is suppressed, since bacterial overgrowth likely contributes to gastric carcinogenesis".
