Plasma metabolites, insulin, and adipokines in 8 week old wild-type and <i>Bmal1</i> null mice.

<p>Plasma glucose (a), free fatty acids (b), insulin (c), adiponectin (d) and leptin (e) levels. Data are the mean ± s.e.m. for <i>n = </i>4 mice of each genotype at each time point, wild-type mice (open circles) and <i>Bmal1</i> null mice (closed circles). The accompanying histograms represent the estimated marginal means ± s.e.m. of the individual gene expression as calculated from the ANOVA. The shaded areas represent the period of darkness. The symbol * indicates that there was a significant difference (<i>P</i><0.05) between the genotypes.
