Effect of AAV-mediated overexpression of ATF5 and downstream targets of an integrated stress response in murine skeletal muscle. Scientific Reports, 11(1), 1-13. https://doi.org/10.1038/s41598-021-99432-4

We previously reported that growth promoter-induced skeletal muscle hypertrophy co-ordinately upregulated expression of genes associated with an integrated stress response (ISR), as well as potential ISR regulators. We therefore used Adeno-Associated... Read More about Effect of AAV-mediated overexpression of ATF5 and downstream targets of an integrated stress response in murine skeletal muscle.

Journal Article
Brearley, M. C., Daniel, Z. C., Loughna, P. T., Parr, T., & Brameld, J. M. (2020). The phosphoenolpyruvate carboxykinase (PEPCK) inhibitor, 3-mercaptopicolinic acid (3-MPA), induces myogenic differentiation in C2C12 cells. Scientific Reports, 10, Article 22177. https://doi.org/10.1038/s41598-020-79324-9

Phosphoenolpyruvate carboxykinase (PEPCK) is a gluconeogenic enzyme with a cytosolic (Pck1/PEPCK-C) and mitochondrial (Pck2/PEPCK-M) isoform. Here we investigate the effect of 3-mercaptopicolinic acid (3-MPA), a PEPCK inhibitor, on C2C12 muscle cells...

Leucine and mTORc1 act independently to regulate 2-deoxyglucose uptake in L6 myotubes (2020)
Journal Article
Yin, Q., Brameld, J. M., Parr, T., & Murton, A. J. (2020). Leucine and mTORc1 act independently to regulate 2-deoxyglucose uptake in L6 myotubes. Amino Acids, 52, 477–486. https://doi.org/10.1007/s00726-020-02829-0

© 2020, The Author(s). Chronic mTORc1 hyperactivation via obesity-induced hyperleucinaemia has been implicated in the development of insulin resistance, yet the direct impact of leucine on insulin-stimulated glucose uptake in muscle cells remains unc...

Changes in expression of serine biosynthesis and integrated stress response genes during myogenic differentiation of C2C12 cells (2019)
Journal Article
Brearley, M. C., Li, C., Daniel, Z. C., Loughna, P. T., Parr, T., & Brameld, J. M. (2019). Changes in expression of serine biosynthesis and integrated stress response genes during myogenic differentiation of C2C12 cells. Biochemistry and Biophysics Reports, 20, Article 100694. https://doi.org/10.1016/j.bbrep.2019.100694

Skeletal muscle is a highly metabolic and dynamic tissue that is formed through the complex and well-organised process of myogenesis. Although there is a good understanding about the role of the Muscle Regulatory Factors during myogenesis, little is...

The commercial pig as a model of spontaneously-occurring osteoarthritis (2019)
Journal Article
Macfadyen, M. A., Daniel, Z., Kelly, S., Parr, T., Brameld, J. M., Murton, A. J., & Jones, S. W. (2019). The commercial pig as a model of spontaneously-occurring osteoarthritis. BMC Musculoskeletal Disorders, 20, Article 70. https://doi.org/10.1186/s12891-019-2452-0

Background: Preclinical osteoarthritis models where damage occurs spontaneously may better reflect the initiation and development of human osteoarthritis. The aim was to assess the commercial pig as a model of spontaneous osteoarthritis development b... Read More about The commercial pig as a model of spontaneously-occurring osteoarthritis.

The beta-adrenergic agonist, Ractopamine increases skeletal muscle expression of Asparagine Synthetase as part of an integrated stress response gene program (2018)
Journal Article
Brown, D., Ryan, K., Daniel, Z., Mareko, M., Talbot, R., Moreton, J., …Brameld, J. M. (2018). The beta-adrenergic agonist, Ractopamine increases skeletal muscle expression of Asparagine Synthetase as part of an integrated stress response gene program. Scientific Reports, 8, Article 15915. https://doi.org/10.1038/s41598-018-34315-9

Synthetic beta-adrenergic agonists (BA) have broad biomedical and agricultural application for increasing lean body mass, yet a poor understanding of the biology underpinning these agents is limiting further drug discovery potential. Growing female p... Read More about The beta-adrenergic agonist, Ractopamine increases skeletal muscle expression of Asparagine Synthetase as part of an integrated stress response gene program.

Effect of sodium 4-phenylbutyrate on clenbuterol-mediated muscle growth (2018)
Journal Article

Previously, we highlighted induction of an integrated stress response (ISR) gene program in skeletal muscle of pigs treated with a beta-adrenergic agonist. Hence we tested the hypothesis that the ER-stress inhibitor, sodium 4-phenylbutyrate (PBA), wo... Read More about Effect of sodium 4-phenylbutyrate on clenbuterol-mediated muscle growth.

Scientific Reports, 6(1), https://doi.org/10.1038/srep28693

We aimed to identify novel molecular mechanisms for muscle growth during administration of anabolic agents. Growing pigs (Duroc/(Landrace/Large-White)) were administered Ractopamine (a beta-adrenergic agonist; BA; 20 ppm in feed) or Reporcin (recombi...
