Schematic shows the regulation of the NGF gene expression and the involvement of C/EBPα in chronic inflammatory pain. Chronic inflammation leads to upregulation of miR-29b expression level which represses the activity of DNMT3b, enhances the demethylation of the NGF gene promoter region, and promotes the binding of C/EBPα with NGF gene promoter, resulting in upregulation of NGF gene expression, and contribute to the maintenance of chronic inflammatory pain
