(A) Levels of phosphorylated ACC were normalized to total ACC in the livers treated with swimming or metformin or both combined. (B) Expression of SREBP2 were normalized to β-actin in the livers intervened by swimming or metformin or both combined. The values represent the mean ± SEM, n = 10/group. The columns with different letter (a, b, c) are significantly different, P<0.05 (ANOVA, SNK). All data in this figure are representatives of three independent experiments. NC: normal control group, DC: GDM control group, DS: GDM treated with swimming group, DM: GDM treated with metformin group, DSM: GDM treated with swimming plus metformin group.
