Background Glycosylation Liver
Protein glycosylation involves the enzymatic attachment of complex sugar chains to proteins. This fundamental process is vital for cellular functions, recognition, and communication. In the context of liver health and disease, glycosylation plays a profound and often dysregulated role. Aberrant N-glycosylation patterns are increasingly recognized as powerful and sensitive indicators for various liver conditions, from early fatty liver disease to advanced hepatocellular carcinoma. These glycan alterations offer immense potential for non-invasive diagnostic strategies and novel therapeutic interventions, moving beyond traditional markers. Creative Biolabs' liver disease related glycosylation analysis service helps you accelerate research, identify novel biomarkers, and enhance therapeutic strategies through advanced glycomic profiling, high-throughput analysis, and cutting-edge mass spectrometry and capillary electrophoresis. We are dedicated to elucidating the crucial role of glycans in liver health and disease. We provide precise and actionable insights, directly addressing key challenges in liver disease research. We empower your project with:

Explore How Our Specialized Services Can Transform Your Liver Disease Research!
Glycosylation Analysis in Disease research is critical because the liver is a central organ for glycoprotein synthesis, meaning changes in its physiological or pathological state are often reflected in the glycan patterns of circulating serum proteins. These glycan alterations offer unique, non-invasive insights, overcoming the limitations of invasive procedures like liver biopsies. Creative Biolabs provides a comprehensive suite of analytical tools to explore these crucial changes. Our service workflow is meticulously designed for clarity, precision, and efficiency, ensuring high-quality, actionable results for your projects.

Main Glycosylation Changes in Liver Disease Research
-
Fucosylation: Often increased, particularly core fucosylation, observed in conditions like NASH, cirrhosis, and HCC. A notable example is the α1-6 core fucosylation of α-fetoprotein, which is a highly specific marker for HCC.
-
Galactosylation: Decreased levels of galactose are frequently seen, especially in IgG glycans, which is a hallmark of chronic inflammatory conditions like NASH and liver fibrosis.
-
Sialylation: The pattern of sialylation changes is mixed, with some sialylated glycans increasing and others decreasing depending on the specific glycan and disease state.
-
Branching: Increased branching of N-glycans (e.g., tetra-antennary glycans) is often associated with HCC. Alterations in bisecting GlcNAc structures are also significant in cirrhosis and HCC.

Published Data
This research introduces GlycoFibroTyper, an innovative technique designed for analyzing N-glycans attached to Immunoglobulin G (IgG) and its subtypes, aiming to establish a distinct biomarker pattern for liver fibrosis. The method is notable for its efficiency, requiring only a small volume of serum and eliminating the need for extensive purification or chemical modifications before analysis. It functions by capturing specific glycoproteins using an antibody array on a slide. Once captured, the N-glycans are enzymatically detached using PNGase F and subsequently identified and quantified through MALDI imaging mass spectrometry. Figure 2 visually outlines this streamlined process.
