Human total serum N-glycome.

Area of Science:

• Biochemistry
• Glycobiology
• Clinical Diagnostics

Background:

• The human total serum N-glycome (TSNG) represents the N-glycosylation patterns of serum glycoproteins.
• N-glycosylation analysis is an emerging diagnostic tool in clinical biochemistry.
• Understanding TSNG is crucial for disease biomarker discovery.

Purpose of the Study:

• To review the N-glycosylation of serum glycoproteins and its role in the TSNG.
• To describe protocols for obtaining N-glycosylation profiles.
• To discuss TSNG variations in various diseases and its diagnostic potential.

Main Methods:

• Literature review of N-glycosylation studies.
• Analysis of protocols for serum N-glycome profiling.
• Synthesis of data on TSNG alterations in disease states.

Main Results:

• N-glycosylation patterns are integral to serum glycoprotein function.
• Various analytical methods exist for characterizing the TSNG.
• Distinct TSNG profiles are associated with specific diseases.

Conclusions:

• TSNG analysis holds promise for diagnosing congenital disorders of glycosylation (CDG).
• TSNG variations are observed in hepatic cirrhosis, inflammatory disorders, autoimmune diseases, and cancers.
• Further research into TSNG applications can enhance clinical diagnostics.
