Empetrum nigrum var. japonicum Extract Suppresses Ultraviolet B-Induced Cell Damage via Absorption of Radiation and Inhibition of Oxidative Stress
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 (); **significantly different from UVB (200 mJ cm−2)-irradiated cells ().
