From: Increased peripheral nerve excitability and local NaV1.8 mRNA up-regulation in painful neuropathy
Detection of NaV1.8 mRNA in the sciatic nerve. A. NaV1.8 mRNA levels were significantly increased in the sciatic nerve ipsilateral to the injury site as compared to contralateral and uninjured DRG. (n = 3; p < 0.05, one-way ANOVA with Tukey post-hoc). B. NaV1.8 mRNA levels in SNE-injured DRG were not significantly different from those of uninjured DRG (n = 4 for uninjured DRG and n = 3 for all other samples). C: Southern blot of the Nav1.8 3' RACE product from contralateral and ipsilateral sciatic nerve. Note the presence of a distinct band representing the expected 3'RACE product of 830 bp. Sequencing of the RACE product confirmed the presence of the 3' end of the NaV1.8 coding region as well as the NaV1.8 3' un-translated region and polyA tail. Tissue was harvested 2 weeks after SNE.
