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

open access: yesThe 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

open access: yesThe 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).

Mitochondrial control of ciliary gene expression and structure in striatal neurons

open access: yesThe 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.

Heterogeneous metabolic response of endothelial cells from different vascular beds to experimental hyperglycaemia and metformin

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Diabetes mellitus is associated with vascular pathology that leads to vascular complications in several tissues, such as retinopathy of the eye. Endothelial dysfunction plays a pivotal role in the progression of each complication.

NAD replenishment restores mitochondrial function and thermogenesis in the brown adipose tissue of mice with obesity

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A high‐fat diet (HFD) induces brown adipose tissue (BAT) whitening, mitochondrial dysfunction (damaged cristae, fragmentation), reduced NAD+ levels and impaired thermogenesis, leading to lower energy expenditure and metabolic inflexibility.

Hypoxia and hypercapnia elicit overlapping but distinct skeletal muscle toxicities

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Hypoxia and hypercapnia cause overlapping skeletal muscle phenotypes, including atrophy, change in myofibre metabolic profile and myogenic response to injury. Both signals operate via distinct cellular pathways. Abstract Skeletal muscle dysfunction is strongly associated with elevated mortality in acute and chronic pulmonary ...

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Cellular mechanisms of radiation‐induced myocyte dysfunction: effects on calcium handling, ion channel regulation and mitochondrial energetics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Dose‐dependent effects of radiation on cardiac electrophysiology and arrhythmia susceptibility. At low radiation doses (left), increased reactive oxygen species (ROS) initiate an ROS–Ca2+ positive feedback loop involving calcium/calmodulin‐dependent protein kinase II (CaMKII) activation, enhanced L‐type Ca2+ current (ICaL ...
