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.

Overcoming the roadblocks to cardiac cell therapy using tissue engineering [PDF]
, 2017 Transplantations of various stem cells or their progeny have repeatedly improved cardiac performance in animal models of myocardial injury; however, the benefits observed in clinical trials have been generally less consistent.

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.

Signal transducer and activator of transcription 2 deficiency is a novel disorder of mitochondrial fission [PDF]
, 2015 Defects of mitochondrial dynamics are emerging causes of neurological disease. In two children presenting with severe neurological deterioration following viral infection we identified a novel homozygous STAT2 mutation, c.1836C4A (p.Cys612Ter), using ...

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 ...

Multiscale modeling of the yeast mitofusin Fzo1
, 2022 Mitochondria are dynamic organelles whose ultrastructural organization is essential in maintaining their quality control and ensuring functional efficiency. The mitochondrial network is the result of both fusion and fission of inner and outer membranes. Tethering and homotypic fusion of mitochondrial outer membranes is mediated by large GTPases of the

Mitochondrial dynamism and heart disease: Changing shape and shaping change [PDF]
, 2015 Mitochondria of adult cardiomyocytes appear hypo-dynamic, lacking interconnected reticular networks and the continual fission and fusion observed in many other cell types.

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).

Miro proteins coordinate microtubule- and actin-dependent mitochondrial transport and distribution [PDF]
, 2018 In the current model of mitochondrial trafficking, Miro1 and Miro2 Rho-GTPases regulate mitochondrial transport along microtubules by linking mitochondria to kinesin and dynein motors.

Mitochondrial control of ciliary gene expression and structure in striatal neurons
The Journal of Physiology, EarlyView.Abstract figure legend Neurons drive animal behaviour by receiving and transmitting information and require energy, primarily supplied by mitochondria, to function. Additionally, neurons need to sense environmental changes to adapt, a function that is locally played by the primary cilia.
