qRT-PCR analysis of <i>Prlr</i> (A, B) and <i>Adipoq</i> (C, D) expression level.

<p>Data are represented as a normalized relative fold change to control. Asterisks represent statistical significance (* p<0.01; *** p<0.001). Control animals are represented in black, stressed animals in grey.

It should be noted that the level of Adipoq expression in hippocampus is very low (C(t) values >40 and beyond detection), which results in a high fold change that is not significant.
