Background: Bed rest (BR) reduces whole-body insulin-stimulated glucose disposal (GD) and alters muscle fuel metabolism, but little is known about metabolic adaptation from acute to chronic BR nor the mechanisms involved, particularly when volunteers...

Mitochondrial dysfunction causes Ca2+ overload and ECM degradation–mediated muscle damage in C. elegans (2019)
Journal Article
Sudevan, S., Takiura, M., Kubota, Y., Higashitani, N., Cooke, M., Ellwood, R. A., Etheridge, T., Szewczyk, N. J., & Higashitani, A. (2019). Mitochondrial dysfunction causes Ca2+ overload and ECM degradation–mediated muscle damage in C. elegans. FASEB Journal, 33(8), 9540-9550. https://doi.org/10.1096/fj.201802298r

Mitochondrial dysfunction impairs muscle health and causes subsequent muscle wasting. This study explores the role of mitochondrial dysfunction as an intramuscular signal for the extracellular matrix (ECM)–based proteolysis and, consequentially, musc...

Journal Article
Deane, C. S., Ames, R. M., Phillips, B. E., Weedon, M. N., Willis, C. R., Boereboom, C., Abdulla, H., Bukhari, S. S., Lund, J. N., Williams, J. P., Wilkinson, D. J., Smith, K., Gallagher, I.

Aging, 11(7), 2111-2126. https://doi.org/10.18632/aging.101904

Optimization of resistance exercise (RE) remains a hotbed of research for muscle building and maintenance. However, the interactions between the contractile components of RE (i.e. concentric (CON) and eccentric (ECC)) and age, are poorly defined. We...
