Effects of different DBP formulations on the protein expression and phosphorylation of MAPKs in mouse dorsal skin tissues. (A) Representative immunoblots of Bax, Bcl-2, Caspase-3, COL1A1, MMP-3, TGF-β, Smad2/3, and GAPDH proteins. (B) The relative expression of Bax quantities. (C) The relative expression of Caspase-3 quantities. (D) The relative expression of Bcl-2 quantities. (E) The relative expression of COL1A1 quantities. (F) The relative expression of MMP-3 quantities. (G) The relative expression of TGF-β quantities. (H) The relative expression of Smad2/3 quantities. (I) Representative immunoblots and phosphorylation levels of ERK, JNK, P38, and GAPDH proteins. (J) The relative ratio of p-ERK/ERK quantities. (K) The relative ratio of p-JNK/JNK quantities. (L) The relative ratio of p-P38/P38 quantities. Data are presented as the mean ± standard deviation; **p < 0.01, ***p < 0.001, and ****p < 0.0001 compared to the normal group; #p < 0.05, ##p < 0.01, ###p < 0.001, and ####p < 0.0001 compared to the Model group, n = 3.
