p38 MAPK siRNA effects on TNF-α-mediated DPP/DSP and MMP-1 expression. Efficacy of p38 siRNA inhibition on total p38 protein expression was quantified after GAPDH normalization, and values are shown above the panels (A). The effects of p38 MAPK siRNA (20 or 60 pmol) on TNF-α-mediated DPP and DSP (B), and MMP-1 (C) expression in dental pulp cells were evaluated. Coomassie blue staining shows equal loading for all lanes. Graphs depict mean and standard deviation from 3 different cell donors; *p < 0.05.
