Core clock genes mRNA levels in obese adipose tissues.

<p>A, Tissue distribution of Per1 mRNA. The Per1 mRNA level of the eye was set at 1, and the mRNA levels of Per1 in other tissues are presented relative to the Per1 mRNA level of the eye. B to J, Changes in adipose core clock genes and adipose-related genes in C57BL/6N (B6) and <i>ob/ob</i> (<i>ob</i>) mice at 8, 25 and 35 weeks of age. n = 3–8 per group. Values are mean ± SEM. **P<0.01; ***P<0.001. ^$P<0.05; ^$$P<0.01; ^$$$P<0.001, compared to 8-week-old B6 mice. ^##P<0.01; ^###P<0.001, compared to 8-week-old <i>ob</i> mice.
