Differential Dose Response of mTOR Signaling to Oral Administration of Leucine in Skeletal Muscle and Liver of Rats

Abstract

Phosphorylation of eukaryotic initiation factor 4E-binding protein 1 (4E-BP1) and 70-kDa ribosomal protein S6 kinase (S6K1) in the rat liver increased in proportion to the amount of leucine administered, ranging from 0.169 to 1.35 g/kg of body weight. In the skeletal muscle, phosphorylation of these factors reached a plateau at 0.675 g/kg of body weight. The sensitivity of mammalian target of rapamycin (mTOR) signaling to leucine in the skeletal muscle appeared to be higher than that in the liver.
