Enhancing effects of ARE on the UV-B-reduced caspase-14 activity levels in HaCaT keratinocytes. The HaCaT cells were subjected to the varying concentrations (0, 10, 50, and 200 μg/mL) of ARE for 1 h prior to the UV-B irradiation. The caspase-14 activity in cellular lysates, expressed as an arbitrary fluorescence unit, was determined using Ac-WEHD-methyl-coumarin amide as a fluorometric substrate. # versus the nonirradiated control. versus the nontreated control (UV-B irradiation alone).
