Inhibitory effects of GAE on expression of melanogenesis-related protein and mRNA. a Western blot assay were performed to estimate protein expression levels of b tyrosinase (TYR), c tyrosinase-related protein-1 (TRP-1), d DCT, and e MITF. Protein loading amounts were confirmed by β-actin expression and f the mRNA levels were examined by real time RT-PCR using glyceraldehydes 3-phosphate dehydrogenase (GAPDH) as control. Data are mean ± standard deviation. **p < 0.01 compared with the vehicle-treated group (n = 3)
