摘要

Glycosylation is found as the most frequent post-translational modification of proteins, frequently altered in tumour cells [1]. Alterations in cellular glycosylation are among the crucial factors involved in cellular signaling, angiogenesis, development and progression of drug resistance in cancer cells. Changes in the expression or activity of glycosylotransferases and in the conformation of peptide backbones are the most important factors, which lead to an increase in the amount of O-GlcNAcylation of intracellular proteins and branched-N-glycans. Abundance of N-glycans correlates not only with the grade of cancer but also with the sensitivity to anticancer treatment [2].
