In addition, other glycosyltransferases, including beta-1 3-glucosyltransferase, mannose-1-phosphate guanylyltransferase beta, and dolichyl-diphosphooligosaccharide–protein glycosyltransferase subunit one and two were also increased for GBM versus control samples (supplemental File S10). This evidence concerns the gene B3GLCT and glioblastoma.
