Figure 1. Effect of fisetin on the viability of UVB-exposed human lens epithelial cells. A: Cell viability of SRA01/04 to different irradiation intensities of UVB (30, 60, and 90 mJ/cm²) is shown at different incubation times of 0, 3, 6, 12, 24, and 48 h. The viability was measured by MTT assay. B: The cell viability of cells pretreated with fisetin at different concentrations (0, 5, 10, 25, 50, and 100 μg/ml) for 1 h before exposure to 30 mJ/cm² UVB was estimated using MTT assay after being cultured for 24 h. Data are represented as the mean±SD from three independent experiments. An asterisk indicates p<0.05.
