Relative levels of FGF21 signaling component mRNAs in ground squirrel tissues.

<p>The relative levels of mRNA were measured in eight tissues from thirteen-lined ground squirrels with 2 squirrels in August active state, 2 squirrels in winter torpid state, and 2 squirrels in IBA state for a total of 6 squirrels. (<b>A</b>) βKlotho mRNA was detected predominantly in liver and white adipose tissue (WAT). (<b>B</b>) FGFR1 mRNA was detected in all tissues at a low level with the highest expression in WAT. Error bars show standard error of the mean.
