Human skeletal muscle is refractory to the anabolic effects of leucine during the postprandial muscle-full period in older men (2017)
Journal Article
Mitchell, W. K., Phillips, B. E., Hill, I., Greenhaff, P. L., Lund, J. N., Williams, J. P., …Atherton, P. J. (2017). Human skeletal muscle is refractory to the anabolic effects of leucine during the postprandial muscle-full period in older men. Clinical Science, 131(21), https://doi.org/10.1042/CS20171230

Leucine modulates muscle protein synthesis (MPS), with potential to facilitate accrual/maintenance of muscle mass. Animal models suggest that leucine boluses shortly after meals may prolong MPS and delay onset of a “muscle-full” state. However, the e...

A novel puromycin decorporation method to quantify skeletal muscle protein breakdown: a proof-of-concept study (2017)
Journal Article
Crossland, H., Smith, K., Atherton, P. J., & Wilkinson, D. J. (2017). A novel puromycin decorporation method to quantify skeletal muscle protein breakdown: a proof-of-concept study. Biochemical and Biophysical Research Communications, 494(3-4), https://doi.org/10.1016/j.bbrc.2017.10.085

The precise roles that the major proteolytic pathways play in the regulation of skeletal muscle mass remain incompletely understood, in part due to technical limitations associated with current techniques used to quantify muscle protein breakdown (MP...

Physiological adaptations to resistance exercise as a function of age (2017)
Journal Article
Phillips, B. E., Williams, J. P., Greenhaff, P. L., Smith, K., & Atherton, P. J. (2017). Physiological adaptations to resistance exercise as a function of age. JCI insight, 2(17), Article e95581. https://doi.org/10.1172/jci.insight.95581

BACKGROUND. The impact of resistance exercise training (RE-T) across the life span is poorly defined. METHODS. To resolve this, we recruited three distinct age cohorts of young (18–28 years; n = 11), middle-aged (45–55 years; n = 20), and...

A novel D2O tracer method to quantify RNA turnover as a biomarker of de novo ribosomal biogenesis, in vitro, in animal models, and in human skeletal muscle (2017)
Journal Article
Brook, M. S., Wilkinson, D., Mitchell, W. K., Lund, J. N., Phillips, B. E., Szewczyk, N. J., …Atherton, P. J. (2017). A novel D2O tracer method to quantify RNA turnover as a biomarker of de novo ribosomal biogenesis, in vitro, in animal models, and in human skeletal muscle. AJP - Endocrinology and Metabolism, 313(6), Article E681-E689. https://doi.org/10.1152/ajpendo.00157.2017

Current methods to quantify in vivo RNA dynamics are limited. Here, we developed a novel stable isotope (D2O) methodology to quantify RNA synthesis (i.e., ribosomal biogenesis) in cells, animal models, and humans. First, proliferating C2C12 cells wer...
