a Relative mRNA levels of CYP24A1, FBP1, HRNR, GAST and TNFRSF10C in control (0 mJ/cm2) and UVB-irradiated (500 mJ/cm2) human epidermal equivalents collected 72 h after irradiation, n = 3 or 4 independent experiments. b Representative H&E staining or immunohistochemical staining (FBP1, K10) of control (0 mJ/cm2) or UVB (500 mJ/cm2) irradiated human epidermal equivalents collected 72 h after irradiation. Scale bars: 50 μm. c Representative immunohistochemical staining for FBP1 of control (0 mJ/cm2) or UVB (500 mJ/cm2) irradiated mice skin collected 72 h after irradiation. Scale bars: 50 μm. Arrows indicated deep-stained upper epidermis. d Representative H&E staining or immunohistochemical staining of mice skin collected at indicated days after irradiation. Scale bars: 50 μm. Data are shown as mean ± s.d. Statistical analyses in (a) were performed with Student’s t-tests. *p < 0.05, **p < 0.01.
