SLC35A2 and gastric cancer: To begin with, MEXPRESS was employed to obtain the data about the relationships of SLC35A2 expression with copy number, clinical data (age at initial pathologic diagnosis, barrettes esophagus, family history of stomach cancer and so on), which revealed a significant relation of SLC35A2 expression to histological type (P = 0.001), sample type (P = 3.504e-4), as well as a strong correlation with the copy number (r = 0.191, P < 0.05) (Fig 3A).
