In addition, we further analyzed the relationship between the overall survival (OS) and the expression of OGT and OGA in 33 major human cancer types using the Gene Expression Profiling Interactive Analysis (GEPIA2, http://gepia2.cancer-pku.cn) package (Tang et al. 2019), the results showed that: (1) OGT expression was related to the OS of BLCA, KIRC, KIRP, LUAD, and READ, although the trends were inconsistent (Fig. 5A). The gene discussed is OGA; the disease is cancer.
