Characterization of Shy1, the Schizosaccharomyces pombe homolog of human SURF1

Scientific Reports
Cytochrome c oxidase (complex IV) is the terminal enzyme in the mitochondrial respiratory chain. As a rare neurometabolic disorder caused by mutations in the human complex IV assembly factor SURF1, Leigh Syndrome (LS) is associated with complex IV ...

Mitochondrial capacities and quality control following short‐ and long‐term weight restoration after simulated anorexia nervosa

Experimental Physiology, EarlyView.
Abstract Anorexia nervosa (AN) is a psychiatric disorder characterized by prolonged caloric restriction and skeletal muscle atrophy. Mitochondrial health is a key mediator of muscle function, yet the role of mitochondria during AN and following weight regain has not been investigated. The objective of this study was to evaluate mitochondrial capacities

(Poly)phenols: Mechanisms of action and efficacy of contemporary supplements for exercise recovery and performance

Experimental Physiology, EarlyView.
Abstract (Poly)phenols are a diverse group of bioactive chemical compounds present in a wide range of plant‐ and animal‐based foods. Several thousands of (poly)phenols exist; many have potent biological effects, most notably antioxidant, anti‐inflammatory and vasodilatory.

Impairments in mitochondrial dynamics and morphology in skeletal muscle of breast cancer patients after a single paclitaxel administration

Experimental Physiology, EarlyView.
Abstract Standard chemotherapy regimens for patients with breast cancer are based on epirubicin–cyclophosphamide (EC) and paclitaxel (TAX) administrations. While it has been shown that first EC administration impairs mitochondrial homeostasis, the isolated effects of TAX have not been studied without previous chemotherapy exposure.

α7nAChR agonist GTS-21 ameliorates sepsis-induced acute kidney injury via MEF2/PGC-1α/HO-1 axis in mice. [PDF]

Clin Transl Med
This diagram illustrates opposing pathways regulating AKI (acute kidney injury). The left pathway shows LPS/TLR4 triggering mitochondrial damage (low MMP, Cyt C release, ROS) leading to apoptosis. The right pathway shows α7nAChR agonists activating MEF2 to upregulate PGC‐1α/HO‐1, promoting mitochondrial biogenesis and inhibiting injury, highlighting ...

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).

Induction of mitochondrial biogenesis enhances neurogenesis and cognitive recovery following ischaemic stroke

Anesthesiology and Perioperative Science
Purpose Stroke can cause severe cognitive impairment in patients. Recently, neurogenesis has been proposed as a potential approach to improve cognitive abilities after stroke.

Angiotensin‐converting enzyme and exercise adaptations: Genetic variability, pharmacological modulation and future directions

The Journal of Physiology, EarlyView.
Abstract figure legend ACE I/D genotype, enzyme activity and integrated physiological adaptations. Upper panel: Conceptual framework linking the ACE I/D polymorphism (left) with circulating/tissue ACE activity (centre; violin plots based on hypothetical data for illustration) and strength/power versus endurance phenotypes (right).
