The relative fold expression of TUBA1A in fibroblasts irradiated by UVB at the indicated time points. (Figure 3-A) TUBA1A expression in fibroblasts 24 h after treatment with different does of UVB, including 0, 25, 50, 75, and 100 mJ/cm2. (Figure 3-B) The time course of TUBA1A 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 group.
