Mean (±SE) percent change of the phosphorylation of A) adipose insulin receptor, B) muscle insulin receptor, C) adipose Akt, D) muscle Akt, and E) adipose AMP kinase (AMPk) from early- (2 wks postweaning, n=5) and late-fasted (7 wks postweaning, n=5) elephant seal pups in response to insulin infusions. F) Representative Western blots for each protein from insulin infused animals. # denotes significantly (p<0.05) different from early fasting; * denotes significantly (p<0.05) different from baseline (T0).
