Abstract:
The glycosylation of cell surface receptors has been shown to regulate each step of signal transduction, including receptor trafficking to the cell surface, ligand binding, dimerization, phosphorylation, and endocytosis. In this review we focus on the role of glycosyltransferases that are involved in the modification of N-glycans, such as the effect of branching and elongation in signaling by various cell surface receptors. In addition, the role of those enzymes in the EMT/MET programs, as related to differentiation and cancer development, progress and therapy resistance is discussed.
Insights
Glycosylation of cell surface receptors regulates signaling pathways. This review explores how N-glycan modification by glycosyltransferases impacts cell signaling, differentiation, and cancer progression.
Area of Science:
- Biochemistry
- Cell Biology
- Molecular Biology
Background:
- Cell surface receptor glycosylation is crucial for signal transduction.
- Glycosylation affects receptor trafficking, ligand binding, dimerization, phosphorylation, and endocytosis.
Purpose of the Study:
- To review the role of glycosyltransferases in N-glycan modification.
- To discuss the impact of N-glycan branching and elongation on cell surface receptor signaling.
- To examine the involvement of these enzymes in epithelial-mesenchymal transition (EMT) and mesenchymal-epithelial transition (MET) programs, cancer development, and therapy resistance.
Main Methods:
- Literature review focusing on glycosyltransferases and N-glycan modification.
- Analysis of signaling pathways regulated by glycosylation.
- Discussion of the role of glycosylation in cancer biology and therapeutic resistance.
Main Results:
- N-glycan modifications by glycosyltransferases significantly influence cell surface receptor signaling.
- Aberrant glycosylation patterns are linked to altered EMT/MET programs.
- Glycosyltransferases play a role in cancer progression and the development of therapy resistance.
Conclusions:
- Glycosyltransferases are key regulators of cell signaling through N-glycan modification.
- Understanding these roles is critical for insights into differentiation, cancer development, and treatment strategies.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
