Stomach
Going from ulcers to cancer
By Dross at 2008-08-23 00:49
 

Researchers have uncovered a big clue as to why some of the bacteria that cause stomach ulcers pose a greater risk for serious problems like stomach cancer than others; it turns out these bacteria can exploit the surrounding stomach cells to protect them from the immune system.

Helicobacter pylori is a bacterial strain that can infect the human stomach and induce inflammation, ulcers, and potentially even stomach cancer. However, only a small fraction of H. pylori infections ultimately lead to cancer, leading researchers to figure out what biological events will trigger this path.

One type of H. pylori strain that seems to increase disease risk is the cag+ strain, which contains a set of proteins that allows it to inject bacterial proteins into cells following attachment to the stomach lining; this interaction between bacteria and gastric cells may be a key contributor to chronic damage.

Early treatment of stomach infection may prevent cancer
By Dross at 2008-05-01 23:55
 

PHILADELPHIA – Based on research using a new mouse model of gastritis and stomach cancer, researchers from the Massachusetts Institute of Technology (MIT) say that prompt treatment of Helicobacter pylori (H. pylori) infections reverses damage to the lining of the stomach that can lead to cancer.

In the May 1 issue of Cancer Research, a journal of the American Association for Cancer Research, researchers say their study results should lay to rest any question about whether – and when - antibiotic treatment of H. pylori can eliminate or reduce risk of developing gastric, or stomach cancer.
