CANX and gastric ulcer: In this study, the glycoforms of the 45S site of CANX and the 271T site of YBX1 were stable in host cells infected with H. pylori isolates from patients with MALT lymphoma; however, glycoforms in these glycosylation sites changed or were deglycosylated in host cells infected with H. pylori isolates from patients with gastritis, gastric ulcers and gastric cancer.
