Folic acid increases global DNA methylation and reduces inflammation to prevent Helicobacter-associated gastric cancer in mice.

abstract：:Much of what is currently accepted on the natural history of Helicobacter pylori-induced gastritis and its relationship with gastric adenocarcinoma rests on the assumption that atrophic gastritis can be correctly identified and reproducibly recognized. Recently, several studies have indicated that pathologists have a ...
