OGT and gastric cancer: Because OGT is the only known enzyme that catalyzes O-GlcNAcylation in mammals 32 and because the content of OGT often reflects the level of O-GlcNAcylation in cells, we further examined the levels of CD36 and OGT mRNA in a publicly available cohort of 300 GC patients (GSE62254) 33, dividing the patients into groups based on the high or low expression of CD36 or OGT relative to the respective median expression level.
