Significance In this study, we identify microRNA-32-5p (miR-32-5p) as a key functional noncoding RNA in trigeminal-mediated neuropathic pain. We report that injury-induced histone methylation attenuates the binding of glucocorticoid receptor to the promoter region of the miR-32-5p gene and decreases the expression of miR-32-5p, in turn promoting the development of neuropathic pain through regulation of Cav3.2 channels. miRNA-mediated gene regulation has been proposed as a therapeutic approach in neuropathic pain. Our findings identify miR-32-5p replenishment as a therapeutic strategy for treating chronic neuropathic pain.
