This experiment was conducted to study the effects of fasting and refeeding on expression of the atrogin-1 and Akt/FOXO signaling pathway in skeletal muscle of chicks. Chicks were fasted for 24 h and refed for 2 h. Atrogin-1 mRNA expression was increased by fasting, and their increment was reduced by refeeding. Phosphorylations of Akt and FOXO1 were not decreased by fasting, but, they were increased by refeeding. These results indicate that refeeding stimulates phosphorylation of Akt/FOXO, resulting in a decrease in atrogin-1 expression in skeletal muscle of chicks.
