Figure 5.
Effect of co-treatment with hesperidin and MG132 (protease inhibitor) on (a) melanin contents and (b) MITF protein expressions in B16F10 cells. Cells were incubated with MG132 with or without hesperidin. Melanogenesis-related protein expressions were analyzed by Western blot. Each percentage value for the treated cells was reported relative to that in α-MSH-stimulated cells. Data were expressed as mean ± SD of three independent experiments carried out in triplicates. ** p < 0.01 as compared to the one treated with hesperidin (30 μM) only.
