The mitochondrial‐targeted antioxidant SkQ1 prevents skeletal muscle mitochondrial‐apoptotic but not necroptotic signalling during ovarian cancer

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend An evaluation of the degree to which mitochondrial hydrogen peroxide emission (mH2O2)‐mediated apoptotic and necroptotic signalling contributes to skeletal muscle atrophy in an orthotopic epithelial ovarian cancer (EOC) model. To determine whether attenuating mH2O2 could prevent regulated cell death signalling and mitigate muscle

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session

Excessive training does not induce mitochondrial dysfunction or impair insulin signalling within skeletal muscle

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Three weeks of overtraining in trained endurance athletes reduced exercise performance without impairing glucose tolerance. In skeletal muscle, overtraining was associated with increased expression of lipid metabolism‐related proteins, enhanced mitochondrial biogenesis and preserved insulin signalling, despite elevated oxidative ...

Mitochondrial physiology in cardiac muscle of deer mice native to high altitude

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude deer mice exhibited evolved changes in mitochondrial energy metabolism and reactive oxygen species (ROS) management that may support cardiac performance under cold hypoxic conditions. High‐altitude mice had increased activity of lactate dehydrogenase (LDH) in the heart, probably enhancing the capacity for lactate ...

Skeletal muscle adaptation to muscle activity and hypoxia: Differential structural and metabolic remodelling

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend There has been controversy about the structural (capillary) response of skeletal muscle to altered O2 status, involving decreased supply (hypoxia) or increased demand (activity). Here we demonstrate that seven days of activation of skeletal muscle by indirect electrical stimulation led to significant expansion of the capillary ...

Seasonal shifts in mitochondrial and reactive oxygen species metabolism are linked to ultrastructural remodelling in honey bees (Apis mellifera)

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Seasonal changes profoundly reshape honey bee mitochondrial metabolism. In winter, bees shift from complex I (CI)‐ to mitochondrial glycerol‐3‐phosphate dehydrogenase (mG3PDH)‐ and complex II (CII)‐linked respiration. Despite lower CI‐linked respiration ATP production is maintained, suggesting increased energetic efficiency in ...
