Protein expression of Myostatin precursor and ActRIIB proteins in crest fat of lean and obese horses and ponies.

<p>Protein expression of myostatin precursor protein and ActRIIB was assessed by Western blot with total AKT used as a loading control. Blots are shown for crest fat expression across all animals with a skeletal muscle sample used as positive control. n = 6/group.
