| Research Abstract |
Protein malnutrition induces lipid accumulation in the liver, which was liked with the enhancement of insulin signaling in the liver. Furthermore, in contrast to the liver, in white adipose tissue(WAT), protein malnutrition suppresses insulin action. Taken together with our results, when energy utilization is reduced under protein malnutrition, energy that is not utilized is preferentially incorporated into the liver and synthesized to lipids. The enhancement of insulin signaling in the liver and the suppression of insulin signaling in WAT may play important roles in the preferential distribution of lipids in the liver during protein malnutrition.
