Summary
Non-starch polysaccharides (NSPs) may target the TLR4 inflammatory pathway to modulate hyperuricemia (HUA). This study prioritizes TLR4-axis genes and suggests fucoidan and alginate for further research in HUA inflammation.
Area of Science:
- Immunometabolism
- Bioinformatics
- Computational Biology
Background:
- Hyperuricemia (HUA) is an immunometabolic disorder linked to gout and inflammation.
- The molecular mechanisms by which non-starch polysaccharides (NSPs) impact HUA-related inflammation are not fully understood.
Purpose of the Study:
- To identify molecular targets of NSPs in HUA-related inflammation using an integrative computational approach.
- To prioritize candidate genes and pathways involved in HUA inflammation modulated by NSPs.
Main Methods:
- Integrative bioinformatics workflow combining transcriptomic data, protein-protein interactions, and single-cell RNA sequencing.
- Mendelian randomization, guided docking, molecular dynamics, and in silico gene knockout analyses were employed.
- Prioritization of the TLR4-centered inflammatory module including TLR4, MSR1, TIRAP, and CXCL8.
Main Results:
- The TLR4-centered module, involving innate immunity and NF-κB pathways, was prioritized.
- Single-cell analysis indicated myeloid cell involvement in gout flares.
- Mendelian randomization suggested a link between TLR4-axis gene expression and serum uric acid levels.
- Fucoidan and alginate showed potential interactions with TLR4.
Conclusions:
- The study provides a framework prioritizing the TLR4 axis in NSP-modulated HUA inflammation.
- Myeloid cell relevance and potential roles for fucoidan and alginate were highlighted.
- Further experimental validation is recommended to confirm these findings.
