Revealing cancer glycome drivers using CRISPR activation screens.

In this study, Wisnovsky and colleagues1 investigate the genetic determinants underlying cancer-associated glycome remodeling. Using genome-wide CRISPR-based approaches, they identified regulators of cell surface glycosylation. Specifically, genetic networks are discovered that upregulate cancer-related ligands of the sialic acid-binding immunomodulatory Siglecs.
