miRNA-mediated GALNT modulation of invasion and immune suppression A sweet deal for metastatic cells

Glycosylation is a key process impacting on many aspects of cellular interactions. We recently reported that a miRNA cluster controls glycosylation by directly targeting N-acetylgalactosamine transferases (GALNTs), resulting in increased tumor invasion and immunosuppression. Here we further discuss how defective glycosylation or GALNTs dysregulation may contribute to tumor progression
