Figure 4From: Amino acids and insulin act additively to regulate components of the ubiquitin-proteasome pathway in C2C12 myotubesMG132 blocks amino acid mediated total proteolysis. Experimental procedures are the same as described under Figure 2. Values are means ± SEM for 2 different experiments performed in at least triplicates. * Indicates differences in protein degradation between 0.2 × PC AA (filled bars) & 1.0 × PC AA (open bars) treatments. ψ Represents differences between MG132 (50 uM) versus control (without MG132) groups.Back to article page
