(A) The inhibitory effect of tyndalized Lactobacillus acidophilus on the expression of MMP-1 and MMP-9 in UVB-irradiated skin. The expression levels of the MMPs were detected by western blot analysis. (B) The inhibitory effects of tyndalized L. acidophilus on the UVB-induced expression of MAPKs. Tyndalized L. acidophilus inhibited the phosphorylation of JNK 1/2, and p38. (C) Tyndalized L. acidophilus inhibited the phosphorylation of ERK or MEK, and ERK 1/2. Lac, tyndalized L. acidophilus; con, control; UV, ultraviolet; MMP, matrix metalloproteinase; JNK, Jun-amino-terminal kinase; MEK, MAPK/ERK kinase; ERK1/2, extracellular signal-regulated protein kinase 1/2. **P<0.01, ***P<0.001 vs. the vehicle group. ##P<0.01, ###P<0.001 vs. the control group.
