Effect of PLG on MAPK/NF-κB expression in TNF-α/IFN-γ-induced HaCaT cells. a p-EKR, p-P38 and NF-κB signaling pathways were determined by western blot. b-d Evaluation of MAPK/NF-κB expression level by image J. Data represent the mean ± SEM. ^###P < 0.05 and ^###P < 0.01 vs. Normal group; ^*P < 0.05, ^**P < 0.01 and ^***P < 0.001 vs. Control group
