Figure 4.

Effects of LQ and LQG on the protein levels of melanogenic enzymes (A) and MITF (B). B16-F1 cells were treated with LQ, LQG, or α-MSH at the indicated concentrations for 48 h, and the protein expressions of melanogenesis-related proteins and MITF were determined using Western blotting as described in Materials and Methods. The data shown are representative of 4–6 independent experiments.
