In this study, downregulation of OGT-mediated O-GlcNAcylation of SNAP-23 promoted the formation of SNAP-23-Stx4-VAMP8 complex and increased exosomes release in ovarian cancer, which increased cisplatin efflux through exosomes and reduced the intracellular cisplatin concentration46. The gene discussed is SNAP23; the disease is ovarian cancer.
