A mechanistic model of nutritional control of protein synthesis in animal tissues.

Regulation of mRNA translation has been held responsible for effects of diet, age, alcohol, hormones, hibernation, disease and hypoxia on protein synthesis in animal tissues. Dietary effects are due to concentrations of amino acids and insulin in circulation that affect activities of two key translational regulators, eukaryotic initiation factor 2 (F2) and eukaryotic initiation factor 4E binding protein 1 (Bp). To construct a platform for prediction of global protein synthesis to nutritional stimuli, a dynamic, mechanistic model of translational control in whole tissues was developed.
