  • Beschreibung: <jats:title>Significance</jats:title> <jats:p> Cancer cells characteristically express proteins with immature O-glycosylation, but how and why cancer cells express immature O-glycans has remained poorly understood. Here, we report that one prevalent mechanism in pancreatic cancer is epigenetic silencing, rather than somatic mutations in a key chaperone, core 1 β3-Gal-T-specific molecular chaperone ( <jats:italic>COSMC</jats:italic> ), required for mature elongated O-glycosylation. We also demonstrate, with the use of well-defined cell systems generated by precise gene editing, that the aberrant O-glycophenotype by itself induces oncogenic features with enhanced growth and invasion. Our study suggests that the characteristic aberrant O-glycophenotype is critical for the development and behavior of cancer and further provides support for immunotherapeutic strategies that target aberrant O-glycans. </jats:p>
