To further understand the potential roles and clinical relevance of OGT in human cancers, our group investigated the OGT expression profiles in 33 major human cancer types in The Cancer Genome Atlas (TCGA, http://cancergenome.nih.gov) database (Weinstein et al. 2013; Blum et al. 2018; Roychowdhury and Chinnaiyan 2016), using Gene_DE module of the Tumor Immune Estimation Resource package (Li et al. 2020) (TIMER2.0, http://timer.cistrome.org). The gene discussed is OGT; the disease is cancer.
