1085-CRISPR Activation Mapping of Cancer Glycome Landscape
Researchers utilized CRISPR activation screens to identify the genetic mechanisms that drive cancer-associated glycome remodeling, specifically the production of Siglec ligands that help tumors evade the immune system. By systematically upregulating thousands of genes, the study discovered that hypersialylation is not controlled by a single master regulator but emerges from a complex network of competing biosynthetic pathways. A significant finding was the role of the enzyme GAL3ST4, which promotes immune evasion in glioma by facilitating the creation of specific structural elements for…
