Actions of Short-Term Fasting on Human Skeletal Muscle Myogenic and Atrogenic Gene Expression

Abstract

Unlike previous observations in catabolic and cachexic diseased states, short-term fasting (40 h) fails to elicit marked alteration of the genes regulating both muscle-specific protein synthesis or atrophy. Greater periods of fasting may be required to initiate coordinated inhibition of myogenic and atrogenic gene expression.
