Intact O-glycopeptides identification by pGlyco 2.0. A Venn diagram showing intact O-glycopeptides in tissues samples. B The abundance of O-glycans in tissue samples. C The binding of intact O-glycopeptides to MUC2 protein in tissue samples. A, B, and C: left, normal control; right, the fourth patient with UC. D Relative abundance of several key glycans of MUC2 O-glycan in control and UC samples. N, tissues from healthy subjects. P4, tissue obtained from the fourth patient with UC. Differences between two groups were assessed using Student’s t-test. *P < 0.05
