Cold and exercise training effects on relative mRNA expression and protein levels from qRT-PCR and western blot assays for plasma membrane-bound fatty acid binding protein (FABPpm), fatty acyl translocase (FAT/CD36) and cytosolic fatty acid binding protein (FABPc) in pectoralis muscles of house sparrow (Passer domesticus). Error bars represent s.e.m. Sample sizes for the different treatment groups were: cold training, N=9; cold training control, N=9; exercise training, N=8; exercise training control, N=8. *Significant differences between treatment groups.
