The increased expression of Nav1.6 in DRG was involved in L5-VRT-induced mechanical allodynia. a The hind paw withdraw threshold was substantially reduced by L5-VRT in rats. n = 12 per group, **P < 0.01 versus the sham group. b The expression of Nav1.6 mRNA was significantly increased following L5-VRT. n = 5 per group, **P < 0.01 versus the sham group. c Representative blots and histogram showed the effect of L5-VRT on Nav1.6 protein. n = 5 per group, **P < 0.01 versus the sham group. d The immunofluorescence staining showed the colocalization of Nav1.6 with IB4 and NF-200, but not GFAP, in DRG. n = 3 per group, Scale bar, 50 μm. e Application of Nav1.6 shRNA significantly attenuated L5-VRT-induced mechanical allodynia. n = 12 per group, **P < 0.01 versus the sham group, ##P < 0.01 versus the corresponding L5-VRT group
