Results are expressed as percentages and represent means ± SEM. WAT = White adipose tissue. Two-way ANOVA yielded p < 0.001 for the effect of treatment and p < 0.001 for the effect of tissue. Comparisons between specific groups performed within rows and within columns yielded the results summarized by the following symbols:

^*p < 0.05 versus control;

^**p < 0.01 versus control by Dunnet's post hoc test;

^ap < 0.01 versus any other tissue;

^bp < 0.05 versus liver and p < 0.01 versus any other tissue;

^cp < 0.05 versus heart and p < 0.01 versus WAT by Tukey's post hoc test.
