Fig. 3. Lack of CNS insulin signaling leads to impaired regulation of BCAA metabolism.
A) Schematic representation of fasting and refeeding protocol in NIRKO mice. B) Plasma BCAA levels at fasting and refed state in NIRKO mice (n ≥ 5 per group). C) Plasma BCAA levels in IRΔWB mice after overnight fasting (n = 8 per group). D) Plasma BCAA levels in IRΔPER mice after overnight fasting (n ≥ 7 per group). E) Hepatic protein expressions of BCKDH and phosphorylated, inactive form of BCKDH by Western blot in IRΔWB mice after overnight fasting (n ≥ 4 per group). F) Hepatic protein expressions of BCKDH and phosphorylated, inactive form of BCKDH by western blot in IRΔPER mice after overnight fasting (n ≥ 4 per group). * p<0.05 compared to control group. Values are mean±SEM.
