dc.description.abstract | Cadmium (Cd) is a heavy metal widely used in industry, and the skin is an important target of this metal. Taxifolin (Tax), a natural source of bioflavonoids found in various conifers, exerts multiple biologic effects on skin cells. However, the mechanisms by which Tax protects keratinocytes against Cd are currently unclear. We investigated the cytoprotective effects of Tax against Cd-induced apoptosis in the human HaCaT keratinocyte. The water-soluble tetrazolium salt (WST-1) assay and Annexin V/propidium iodide double-staining assay results showed that Cd-induced cell death was lower in cells treated with Tax (0-100 mu M) than in cells treated with Cd alone. Additionally, a reduction of Cd-induced DNA fragmentation by Tax was shown by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end labeling assay. The levels of reactive oxygen species were also lower in Cd/Tax-treated cells than in Cd-treated cells. We employed a two-dimensional electrophoresis-based proteomic analysis to identify treatment-related alterations in protein expression. Tax downregulated cathepsin B and D and upregulated hsp27, cyclophilin A, and peroxiredowin-1. Western blotting confirmed the downregulation of cathepsin B and D and the upregulation of hsp27. The cytoprotective effects of Tax against Cd-induced apoptosis were also characterized by the changes in the activity of caspase 3, -7, poly ADP-ribose polymerase, the cellular proliferation-related ERK1/2, and AKT. Furthermore, the levels of cell cycle-related proteins, such as SP1 and p21, decreased, whereas p53 level increased. We concluded that Tax reduced Cd cytotoxicity and Cd-induced apoptosis by inhibiting the apoptotic pathway. | - |
