Figure 4From: Aging impairs contraction-induced human skeletal muscle mTORC1 signaling and protein synthesisTotal protein content. Representative immunoblot images for Akt, mammalian target of rapamycin (mTOR), S6 kinase (S6K)1,, eukaryotic initiation factor 4E-binding protein (4E-BP)1, extracellular signal-regulated kinase (ERK)1/2, ribosomal protein (rp)S6 and α-tubulin. Protein content did not change during postexercise recovery in either group (P> 0.05).Back to article page
