Figure 9. Changes in the protein levels of members of the inhibitor of apoptosis (IAP) protein family comparing euthermic (EC) and hibernating (LT) conditions in ground squirrel tissues. (A) The relative expression levels of cIAP1/2. (B) The relative expression levels of xIAP.

Tissues are brown adipose tissue (BAT), skeletal muscle (MUS), heart (HRT), liver (LIV), kidney (KID) and brain (BRN) of thirteen-lined ground squirrels. Representative Western blots are shown with sampling points labeled to the left and tissues labeled above the bands. Histograms show mean standardized band densities (±S.E.M., n = 4 independent protein isolations from different animals). Data were analyzed using the Student’s t-test; * values are significantly different from EC, p < 0.05.
