Previous studies have observed progressively higher OGT and O-GlcNAcylation levels as gastric cancer (GC) progresses: O-GlcNAcylation and OGT levels were higher in GC with the intestinal type, higher pathological and clinical stage, and more lymph node metastasis (Jang and Kim 2016). The gene discussed is OGT; the disease is gastric cancer.
