. β-actin was used as a loading control. The blots shown are representative of three independent experiments that had similar results. (C) HaCaT cells (0 × 00^0^ cells/well) were treated with the indicated concentrations of WE(0-0) and AL(0-0) for 00 h and cell viability was determined by MTT assay. Results of independent experiments were averaged and are shown as percentage cell viability compared with the viability of untreated control cells. (
