Effects of ARE on the UV-B-reduced filaggrin protein (a) and mRNA (b) levels in 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. In (a), the filaggrin proteins in cellular lysates were determined using western blotting analysis. GAPDH was used as a protein loading control. In (b), the filaggrin mRNA levels were determined using quantitative real time RT-PCR analysis. In (a), the relative band strength, expressed as the percentage of control, was determined with densitometry using the ImageJ software that can be downloaded from the NIH website. # versus the nonirradiated control. ; ; versus the nontreated control (UV-B irradiation alone).
