Gene expression (mean ± SE) in the cerebral cortex and liver of mice of different genotypes and ages as indicated.

<p><i>Wt</i> = wild type mice; M8 = <i>Mct8KO</i>; L2 = <i>Lat2KO</i>; M8L2 = <i>Mct8Lat2KO</i>. Measurements were by qPCR, and the data expressed relative to 18S RNA. Significance of differences was calculated by one way ANOVA and the Tukey posthoc test. Only relevant significant comparisons are indicated. * P<0.05. ** P<0.01. *** P<0.001. <i>Hr</i>: Hairless mRNA. <i>Sema7a</i>: Semaphorin 7a mRNA. <i>Klf9</i>: Kruppel factor 9, or BTEB mRNA. P0, P5, P15, P21: postnatal days 0, 5, 15, or 21.
