Western blot analysis of TGF‐β, p-Smad2, and p-Smad3. The bar graph shows quantitative analysis of the TGF‐β, p-Smad2, p-Smad3 and β-actin proteins, and the results were normalized to the RAW246.7 group (A–C). TGF‐β, p-Smad2, p-Smad3 and β-actin protein expression in different groups was detected by Western blot (D). The data are shown as the means ± SDs, one-way ANOVA followed by Tukey's multiple comparison test, ****P < 0.0001
