Mitochondrial alterations as potential early events in neuromuscular junction remodelling with muscle disuse

Experimental Physiology, EarlyView.
Abstract Physical inactivity impairs neuromuscular health, promoting skeletal muscle atrophy, mitochondrial changes, and neuromuscular junction (NMJ) instability. However, the interplay between mitochondria and NMJ alterations in the context of muscle disuse remains underexplored.

Mitophagy in skeletal muscle: Impact of ageing, exercise and disuse

Experimental Physiology, EarlyView.
Abstract Skeletal muscle plays an important role in whole‐body health, quality of life and regulation of metabolism. The maintenance of a healthy mitochondrial pool is imperative for the preservation of skeletal muscle quality and is mediated through mitochondrial quality control consisting of mitochondrial turnover mediated by a balance between ...

Heat treatment combined with hybrid exercises retraining mitigates cellular markers of protein turnover after hindlimb suspension in male mice: A pilot study

Experimental Physiology, EarlyView.
Abstract Recent evidence suggests that heat treatment (HT) and resistance training can limit skeletal muscle mass loss during immobilization. However, the effects of repeated HT sessions combined with hybrid exercises (EX), which promote both endurance and resistance responses, on muscle protein turnover following hindlimb unloading (HU) remain ...

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

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.

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.

155 | Mitochondrial dynamics and therapeutic insights in spinal muscular atrophy: effects of mfn2 boosting in motoneurons and human fibroblasts

Journal of Biological Research
Mitochondria form a dynamic network whose spatial architecture is governed by the balance between fusion and fission, known as mitochondrial dynamics.

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

The Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

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).
