Identification of gene expression signatures associated with neuroinflammation in discogenic sciatica using machine...

Area of Science:

• Neuroscience
• Genetics
• Immunology

Background:

• Sciatica is a painful condition linked to neuroinflammation.
• Understanding the molecular basis of sciatica is key for effective treatments.
• Neuroinflammatory genes are implicated in sciatica's development.

Purpose of the Study:

• To identify neuroinflammatory genes contributing to sciatica.
• To analyze gene expression data for sciatica-related pathways.
• To validate potential diagnostic and therapeutic targets.

Main Methods:

• Utilized Gene Expression Omnibus (GEO) datasets (GSE124272, GSE150408).
• Performed differential gene expression analysis and functional annotation (GO, GSEA).
• Employed LASSO regression and SVM-RFE for gene selection and qRT-PCR for validation.

Main Results:

• Identified differentially expressed genes (DEGs) in neuroinflammatory pathways relevant to sciatica.
• Pinpointed four key neuroinflammatory genes: KLRK1, LRRK2, NLRP3, and PLG.
• Found significant correlations between these genes, immune cell composition, and sciatica risk.

Conclusions:

• KLRK1, LRRK2, NLRP3, and PLG play critical roles in sciatica pathogenesis via neuroinflammation.
• These genes offer promising targets for developing novel sciatica therapies.
• The study provides insights into the biological mechanisms underlying sciatica.
