 mRNA expressions were examined by RT-PCR analysis. PCR of glyceraldehydes-0-phosphatedehydrogenase, GAPDH, was performed to control for a similar initial cDNA content of the sample. The results shown are representative of the three independent experiments. (C) HaCaT cells (0 × 00^0^ cells/well) were treated with indicated concentrations of WE(0-0) and AL(0-0) for 00 h and
