Fucosyltransferase 8 modulates receptor tyrosine kinase activation and temozolomide resistance in glioblastoma cells.

ABSTRACT: Alteration of extracellular glycosylation is a hallmark of malignant characteristics. In this study, we revealed that fucosyltransferase 8 (FUT8), an enzyme that mediates the core fucosylation of N-linked glycosylation, is an important regulator of malignant characteristics in human glioma that acts by modifying the activities of both the HGF receptor (MET) and epidermal growth factor receptor (EGFR). mRNA and protein expression levels of FUT8 were frequently upregulated in gliomas, and these events were showed positive correlations with advanced tumor grade, recurrence, and decreased overall survival. Silencing FUT8 expression in glioma cells suppressed cell growth, migration, and invasion, whereas overexpression of FUT8 was sufficient to enhance these phenotypes. Mechanistic investigatio
