Fig 1: PPI network of DEGs. (A) PPI network of DEGs. (B) Identification of a sub-network. (C) Gene expression of CXCL9, MMP9, C3 in DRG tissue after surgery were validated by reverse transcription-quantitative PCR. (D) The level of DRG, C3, MMP9 and CX3CL9 protein after sham and LID surgery and isolated DRG tissues. *P<0.05, **P<0.01, ***P<0.001. PPI, protein-protein interaction; DEGs, differentially expressed genes; DRG, dorsal root ganglia; LID, localized inflammation of the dorsal root ganglion; CXCL9, C-X-C motif ligand 9; MMP9, matrix metallopeptidase 9; C3, complement component 3.
