In addition, another study examined differential gene expression in DRG collected from mice in a neuropathic pain model – when we examined this gene list we found that 17/97 of the regulated genes were matrisome genes, and of these matrisome genes, 3 genes overlapped with the differentially expressed matrisome genes in DRG from patients with neuropathic pain we described, Lum, lumican, Prg4, proteoglycan 4, and Ccl8, chemokine (C-C motif) ligand 8 (Bangash et al., 2018). Here, PRG4 is linked to neuropathic pain.
