SREBP1 and SREBP2 expressions in the liver. KK-Ay mice were fed with the AIN-93G diet with or without 0.2% fucoxanthin for 4 weeks. Liver lysates were prepared for Western blotting, and primary antibody binding was detected by appropriate secondary antibodies for chemiluminescence as described under “Materials and Methods”. SREBP1 and SREBP2 levels are presented relative to control group after normalization for β-Actin levels. Each value represents the mean ± standard error (n = 6). Asterisks show significant differences from the control group (** P < 0.01).
