Cellular glycosylation occurring during cancer development and progression represent key features of tumor cell malignant behavior. In this publication, the authors preview and discuss the findings of Nguyen et al. (Cancer Cell. 2017 Nov 13;32(5):639-653) who identified a molecular mechanism in which the relocation of a glycosyltransferase mediating protein O-glycosylation initiation, from the Golgi to endoplasmic reticulum, leads to aberrant glycosylation.

As células produzem vesículas para o meio extracelular as quais apresentam uma composição característica de ácidos nucleicos, proteínas, lípidos e glicanos. As vesículas produzidas têm origem nos endossomas multivesiculares ou na membrana plasmática e são veículos de biomoléculas constituintes das células de origem para o meio extracelular, sendo encontradas em biofluidos humanos. As células tumorais também produzem vesículas extracelulares, as quais contém moléculas desreguladas na doença e constituindo, por conseguinte, alvos muito promissores para a identificação de biomarcadores.
