Effects of QCN on MAPK signaling pathway in the spinal cords of BPA rats at week 8 post-avulsion. A The protein levels of B-Raf, p-MEK and p-ERK as determined by western blot. Quantification of B B-Raf, C p-MEK to MEK, and D p-ERK to ERK proteins in the ventral horn of the C6-7 spinal segments. Data are expressed as the mean ± SEM (n = 3). ^### p < 0.001 vs the sham group; *p < 0.05 and **p < 0.01 vs the vehicle group
