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

The 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 ...

Insights from animal models: Dissecting the independent roles of oxygen and nutrients in the fetal origins of cardiovascular disease

The Journal of Physiology, EarlyView.
Abstract figure legend This review utilized animal models of complicated human pregnancies that result in reduced fetal nutrient or oxygen delivery, or combined nutrient and oxygen delivery, to elucidate their independent and/or synergistic contributions to the development of high‐risk cardiac phenotypes.

A high‐fat, high‐sucrose diet exacerbates muscle and metabolic pathology and undermines glucocorticoid efficacy in dystrophin‐deficient mice

The Journal of Physiology, EarlyView.
Abstract figure legend A high‐fat, high‐sucrose diet (HFHSD) exacerbated muscle and metabolic dysregulation in mdx mice while also altering the physiological response to prednisolone (Pred) In diaphragms of control diet (CD)‐fed mdx mice, prednisolone treatment improved muscle function and reduced fibrosis, inflammatory signalling, and mitochondrial ...

SARS‐CoV‐2 targets mitochondria, exacerbating COVID‐19 pneumonia

The Journal of Physiology, EarlyView.
Abstract figure legend Following entry into airway epithelial cells (AECs), SARS‐CoV‐2 releases its single‐stranded RNA into the cytoplasm, where it is translated into viral proteins. Several of these viral proteins localize to mitochondria and interact with key mitochondrial components.

Hypoxia‐induced vulnerability of the somatosensory nervous system

The Journal of Physiology, EarlyView.
Abstract figure legend Sensory neurons are highly energy dependent and rely on sufficient oxygen availability to maintain metabolic stability and effective neurocommunication. Within the somatosensory system, even modest reductions in tissue oxygen tension impair neuronal respiration, forcing a shift toward less efficient metabolic pathways that ...

Exercise training prior to and during cancer in mice preserves muscle mass, reduces tumour weight and suppresses molecular mediators of cachexia

The Journal of Physiology, EarlyView.
Abstract figure legend PoWeR training (11.5 weeks of voluntary wheel running with progressively increased resistance) before and during cancer attenuates muscle loss, limits tumour growth, drives a transition toward a more oxidative muscle phenotype (IIB‐to‐IIA shift), downregulates cachexia‐associated pathways and enhances mitochondrial performance in

Restoration of neuromuscular function by mitochondrial transplantation in injured mouse skeletal muscle

The Journal of Physiology, EarlyView.
Abstract figure legend Mice received chemical injury (cardiotoxin) in the tibialis anterior muscle of one limb, and the contralateral muscle was injected with phosphate‐buffered saline (PBS) as a sham control. Mice then received PBS or mitochondria suspended in PBS into the tail vein.
