Summary
N-glycans, sugar molecules attached to proteins, show potential as biomarkers for diabetes. They may help identify diabetes risk, subtypes, and guide management strategies for various forms of the disease.
Area of Science:
- Endocrinology
- Metabolic Disorders
- Glycobiology
Background:
- Diabetes mellitus is a heterogeneous metabolic disorder defined by hyperglycemia.
- Identifying reliable biomarkers is crucial for disease predisposition, diagnosis, and management.
- N-glycans, protein-linked oligosaccharides, are increasingly recognized for their roles in metabolic diseases.
Purpose of the Study:
- To explore the role of N-glycosylation in four major diabetes subtypes: type 1, type 2, gestational, and monogenic diabetes.
- To review N-glycans as potential markers for diabetes development, diagnosis, and complications.
- To discuss the functional impact of N-glycans in glucose metabolism and insulin secretion.
Main Methods:
- Review of existing literature on N-glycans and diabetes.
- Analysis of genome-wide association studies linking glycosyltransferase genes to diabetes.
- Examination of studies investigating N-glycome alterations in diabetes patients.
Main Results:
- N-glycome profiles are altered in type 2 diabetes and can indicate predisposition.
- Glycosyltransferase genes are implicated as causal in type 1 and type 2 diabetes.
- N-glycans may play a role in regulating glucose-stimulated insulin secretion.
Conclusions:
- N-glycans represent promising biomarkers for various diabetes subtypes.
- Understanding N-glycosylation is vital for advancing diabetes diagnosis and therapeutic strategies.
- Further research into N-glycans could unlock novel approaches for diabetes management.

4.1K
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...

7.9K
Glycosylation, the most common post-translational modification for proteins, serves diverse functions. Adding sugars to proteins makes the proteins more resistant to proteolytic digestion. Glycosylated proteins can act as markers and receptors to promote cell-cell adhesion. Additionally, they have many essential quality control functions in the cell, such as correct protein folding and facilitating transport of misfolded proteins to the cytosol, which can be degraded.

3.4K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

3.1K
Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
