Study Design:
Bioinformatics analysis.
Objectives:
To explore the diagnostic signatures for patients with spinal cord injury (SCI).
Setting:
Shenyang, China.
Methods:
After DEGs screening, WGCNA was employed to screen the SCI-related genes. Then the SCI-related genes were intersected with DEGs and PANoptosis-related genes, and DPRGs were obtained, followed by PPI network construction. Diagnostic genes were identified by machine learning, followed by nomogram construction, immune infiltration analysis, GSEA, mRNA-miRNA and mRNA-TF networks establishment, and potential drugs screening.
Results:
Total 277 PANoptosis-related genes, 3269 DEGs, and 1417 SCI-related genes were identified, and intersection analysis yielded 28 intersection genes, which were considered DPRGs. Subsequently, seven diagnostic genes were identified by machine learning, namely FASLG, AVEN, PSMB3, EXOG, CASP4, CASP5, and TLR4. The CASP4 and TLR4 were both enriched in Toll-like receptor signaling pathway and NOD-like receptor signaling pathway, etc. Seventeen immune cells shown significant difference between SCI and control samples, including macrophage, activated dendritic cell, and neutrophil, etc. CASP4 and TLR4 were strongly associated with macrophage, activated dendritic cell and neutrophil, etc. The nomogram of CASP4 and TLR4 was constructed with powerful predictive accuracy. Finally, the potential drugs were predicted, including emricasan, neoceptin-3, and resatorvid, etc. CONCLUSIONS: Seven PANoptosis-related genes, namely FASLG, AVEN, PSMB3, EXOG, CASP4, CASP5, and TLR4, and the constructed nomogram based on CASP4 and TLR4 might viable diagnostic signatures for SCI, and conducive to the prevention and diagnosis of SCI in clinical practice.
