The relative fold expression of VIM in fibroblasts irradiated by UVB at the indicated time points. (Figure 4-A) VIM expression in fibroblasts 24 h after treatment with different does of UVB, including 0, 25, 50, 75, and 100 mJ/cm2. (Figure 4-B) The time course of VIM expression after treatment with 125 mJ/cm2 UVB. The error bars represent the standard deviation. The experiments were performed in triplicate. * p < 0.05 compared with the control groups; # p < 0.05 compared with the group irradiated with a dose of 50 mJ/cm2; Δ p < 0.05 compared with the group 24 h after exposure.
