The regulation of skeletal muscle is dependent upon the balance between protein synthesis and protein degradation. The FoxO1 transcription factor engages in an important role in regulating skeletal muscle hypertrophy through upregulation of atrophy related genes (i.e. MAFbx/atrogin-1). Studies have shown that FoxO1 regulates skeletal muscle atrophy through both apoptotic and proteolytic pathways in various tissues. However, the interaction between FoxO1 overexpression and protein synthesis is unknown. The hypotheses tested include: i) the overexpression of FoxO1 in vitro suppresses skeletal muscle protein synthesis and ii) suppression of skeletal muscle protein synthesis is due to suppression of ribosome biogenesis. An in vitro model was used in which FoxO1 estrogen receptor fusion proteins were transfected into skeletal muscle myoblasts and grown into myotubes. The differentiated myotubes were treated with 4-hydroxytamoxifen (4-OHT) to activate the FoxO1 estrogen receptor fusion proteins and with insulin as a hypertrophic stimulus for 30 minutes, 60 minutes, and 120 minutes. The cells were treated with [3H] phenylalanine to measure total protein synthesis upon FoxO1 overexpression. In addition, expression of key anabolic molecules including Akt, p70s6k, ribosomal protein S6, and Cyclin D1 activity was assessed via western blot. Our findings show that i) FoxO1 overexpression significantly suppresses protein synthesis in differentiated myotubes, ii) despite treatment with insulin; FoxO1 overexpression blunts protein synthesis compared to control myotubes, iii) FoxO1 overexpression suppresses activation of Akt and ribosomal protein S6. In addition, insulin treatment did not elevate phosphorylation of ribosomal protein S6 upon FoxO1 overexpression. In this study, the major finding is that FoxO1 overexpression suppresses protein synthesis prior to any phenotypic loss of protein content in a ribosomal protein S6 dependent manner. In addition, total protein synthesis is suppressed despite treatment with insulin. Therefore, decreased skeletal muscle size is attributed to both increased protein degradation and suppression of protein synthesis. It can be speculated that the suppression of protein synthesis is due, at least in part, to alterations in ribosomal biogenesis. Future direction will focus on ribosomal biogenesis to elucidate the mechanism to which FoxO1 suppresses protein synthesis.

Resistance exercise (RE) is purported to induce muscle protein accretion primarily by stimulating muscle protein synthesis (MPS), with its effect potentiated by providing a protein or amino acid (AA) supplement post exercise. Glutamine, a conditionally essential AA, is increasingly recommended to improve exercise performance, but it is poorly soluble and unstable in sports drinks. This limitation can be overcome by combining L-glutamine with L-alanine to form a dipeptide (AlaGln). The first study demonstrated that AlaGln supplementation post resistance exercise significantly reduced the phosphorylation of AMPK and NF-kB p65 without activating intracellular signals for MPS. This study also showed that whey protein (WP) activated the mTOR signaling pathways without affecting signaling proteins that controls muscle protein breakdown (MPB). The results provide indirect evidence that AlaGln blocks MPB via suppressing the activation of AMPK-FOXO3A and NF-kB p65, while WP promotes MPS. Recent research suggests that adding carbohydrate (CHO) to a protein supplement post exercise can produce greater protein accretion and subsequently increase the magnitude of resistance training adaptation relative to protein supplementation alone. Early studies from our laboratory found that co-ingestion of CHO and protein, as compared with CHO or protein intake individually, had a greater effect on the activation of anabolic signaling proteins. However, the effect of CHO plus protein on MPS and muscle adaptation is controversial. The second study demonstrated that adding CHO to a protein supplement (CP) accelerated MPS via activating the mTOR-signaling pathway in comparison with placebo (PLA) and WP during early exercise recovery, but CP did not affect signaling proteins that regulate MPB. The third study found that CP enhanced muscle strength relative to PLA and WP. The greater strength development in CP appeared due to increased myofibrillar protein content. Increased muscle hypertrophy occurred without an increase in myonuclei suggesting satellite cell activation was not required for muscle fiber development. Taken together, the results of this series of studies suggest that 1) AlaGln inhibits MPB following acute RE; 2) Adding CHO to a protein supplement accelerates muscle recovery by stimulating MPS, and increases the magnitude of muscle strength by accumulating more myofibrillar protein in comparison with PLA and WP.

Dietary supplement companies and the food industry spend millions to reach resistance trainers—often with exaggerated marketing messages—while health practitioners continue to counsel athletes that their interest in protein is misguided and even dangerous. There appears to be a disconnect between scientists and almost everyone else in sports nutrition. With so much conflicting information, it’s difficult to know who to believe. With contributions from the world’s foremost experts, Dietary Protein and Resistance Exercise delivers the uncut scientific truth about the role of dietary protein in the well-being of athletes. Updating and clarifying the issues surrounding purposeful protein intake and resistance trainers, this volume: Reviews the science-related history of protein and its consumption among strength athletes Analyzes the mechanisms behind what proteins do in muscle cells Describes protein’s effect on performance, recovery, and body composition Explores various populations that actively employ resistance training and dietary protein Discusses timing, type, and safety data regarding liberal protein diets and related supplements Includes sidebars, practical examples, and case studies—translating the science into a practical understanding of various protein-related topics Separating fact from fiction and providing the hard science behind the numbers, this volume demonstrates how changes in dietary protein intake may lead to measurable improvements in body composition, energy levels, and athletic performance.

A succinct review of hundreds of studies on the regulation of protein mass and protein turnover in the human body. The book summarizes the biochemistry of protein synthesis and breakdown, and explains the methods that are used to examine protein metabolism in humans, together with their limitations. Chapters review the effects of nutrition, hormones, metabolic substrates, and physical activity, while various topics of clinical interest include cancer, diabetes, tissue injury, pregnancy, renal disease, muscular dystrophies, and other conditions. Normal values are presented for turnover of proteins in the whole body and individual organs, and for turnover of many individual proteins. This is thus a valuable resource for physiologists, nutritionists, and clinicians interested in the regulation of body protein stores in health and disease. For scientists primarily interested in the basic aspects of protein metabolism, it shows how the basic knowledge is being applied to the study of humans.
