Empetrum nigrum var. japonicum Extract Suppresses Ultraviolet B-Induced Cell Damage via Absorption of Radiation and Inhibition of Oxidative Stress

Figure 1

ENE restores cell viability in UVB-irradiated human HaCaT keratinocytes. Cells were pretreated with ENE (50 μg mL⁻¹) and exposed to UVB radiation 1 h later. Following an incubation period of 24 h, cell viability was assessed via the MTT assay. *Significantly different from UVB (150 mJ cm⁻²)-irradiated cells (𝑃<0.05); **significantly different from UVB (200 mJ cm⁻²)-irradiated cells (𝑃<0.05).
