No associations were observed for any of the clinical parameter with NF-κB1–DNA binding or with CGRP, SP, or TRPV1 protein expression except that of nuclear ReLA levels which correlated negatively with ODI (r = −0.507; p = 0.045; n = 16) in DDD patients. This evidence concerns the gene NFKB1 and Dowling-Degos disease 1.
