New prognosis predictor and target for gastric cancer
Apr. 7, 2022—The protein CGA — a subunit of glycoprotein hormones — is a biomarker that predicts chemoresistance in gastric cancer and could be targeted along with EGFR to restore chemosensitivity.
H. pylori, lipid loss and stomach cancer
Jan. 17, 2022—H. pylori infection — a strong risk factor for stomach cancer — changes the composition of stomach lipids, which could offer new biomarkers for detecting premalignant changes, Vanderbilt researchers discovered.
Oral microbes and gastric cancer
Dec. 13, 2021—Studies in three large population cohorts that include Asian, African American and European American people support a role for the oral microbiota — the collection of microbial species in the mouth — in gastric cancer development.
New marker for metaplasia
Oct. 14, 2021—A protein that transports water, called aquaporin 5, is expressed by cells undergoing changes that may increase risk for gastric cancer development, Vanderbilt researchers discovered.
Study finds genetic factor undermines H. pylori treatment
Aug. 4, 2021—Helicobacter pylori, a stomach-dwelling bacterium, is a strong risk factor for gastric cancer, peptic ulcers and other debilitating gastrointestinal disorders. Yet efforts to eradicate it using a combination of antibiotics and proton pump inhibitors (PPIs), which suppress gastric acid production, often fail.
Study gauges specific site stomach cancer risks among ethnic groups
Aug. 6, 2020—Non-white Americans, especially Asian Americans, are at disproportionately higher risk for gastric cancer compared to non-Hispanic white Americans. A new study breaks down this risk according to specific ethnicities and locations within the stomach.
Stomach bug hit-and-run
Jul. 23, 2020—The H. pylori machinery that “injects” an oncoprotein into stomach cells contributes to the development of gastric cancer, Vanderbilt researchers demonstrate.
Researcher works on protocols to implement screening for gastric cancer
Apr. 2, 2020—A Vanderbilt gastroenterologist is helping lead an effort to establish screening guidelines for gastric cancer in the United States, where the number of people at risk for the cancer is increasing as the nation’s population becomes more diverse.
Powering H. pylori pathogenesis
Feb. 6, 2020—Timothy Cover and colleagues report new insights into the sources of energy used by a bacterial “machine” linked to the pathogenesis of stomach cancer.
VUMC study sheds light on gastric cancer development
Jan. 16, 2020—VUMC researchers have created the world’s first laboratory model of precancerous changes in the lining of the stomach, a scientific tour de force that is helping to unlock the mysteries of gastric cancer development.
A step toward gastric cancer
Oct. 3, 2019—New research findings provide insight into the detrimental events that develop in response to H. pylori infection.
Receptor’s role in stopping H. pylori
Apr. 25, 2019—The immune receptor NOD1 may be a prime target for preventing or treating H. pylori infections — the most significant risk factor for stomach cancer, Vanderbilt researchers have discovered.
