infection induces gastric precancerous lesions and persistent expression of Angpt2, Vegf-A and in a mouse model.

Introduction: colonizes the gastric mucosa and induces chronic inflammation.

Methods: Using a mouse model of -induced gastritis, we evaluated the mRNA and protein expression levels of proinflammatory and proangiogenic factors, as well as the histopathological changes in gastric mucosa in response to infection. Five- to six-week-old female C57BL/6N mice were challenged with SS1 strain.
