Hypoxia and the cytoskeleton

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic outlining the activation of hypoxia‐sensitive pathways, the influence of hypoxia and associated pathways on the cytoskeleton, and the impact of these on disease progression. Abstract A highly‐regulated and dynamic cytoskeleton is vital for functional cellular physiology and the maintenance of homeostasis.

Demonstration of beat‐to‐beat, on‐demand ATP synthesis in ventricular myocytes reveals sex‐specific mitochondrial and cytosolic dynamics

The Journal of Physiology, EarlyView.
Abstract figure legend Beat‐locked mitochondrial ATP transients reveal modular, sex‐specific bioenergetic control during excitation–contraction coupling. A, each action potential activates L‐type CaV1.2 channels, producing a Ca2+ influx that triggers ryanodine receptors (RyR2) and elicits SR Ca2+ release.

Human‐derived cardiac‐neural microtissues reveal catecholaminergic polymorphic ventricular tachycardia is also a disease of the sympathetic neuron

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic diagram illustrating the proposed pathway in which regulatory defects might occur in sympathetic neurons derived from hiPSC in catecholaminergic polymorphic ventricular tachycardia (CPVT). Specifically, enhanced calcium transients appeared to derive from three sources: enhanced membrane excitability (due to loss of ...

Mitochondrial permeability transition in skeletal muscle phenocopies muscle alterations seen in cancer cachexia and other wasting conditions

The Journal of Physiology, EarlyView.
Abstract figure legend Skeletal muscle wasting conditions are characterized by muscle fibre atrophy, mitochondrial respiratory dysfunction, mitochondrial depletion and fragmentation of acetylcholine receptor (AChR) cluster at the neuromuscular junction.

Intracellular mechanosensation in intestinal smooth muscle: Piezo1 complexes amplify signalling beyond the surface

The Journal of Physiology, EarlyView.
Abstract figure legend Mechanosensation is not confined to the cell surface. In intestinal smooth muscle Piezo1 is predominantly intracellular (86%), where it forms a nanoscale (<40 nm) complex at the sarcoplasmic reticulum (SR)–plasma membrane junction. Within this sensor–amplifier–effector axis intra‐Piezo1 is the sensor that detects force at the SR,

β‐hydroxy‐β‐methylbutyrate improves fast‐twitch muscle function, histopathology and mitochondrial respiration in the D2.mdx dystrophic mouse

The Journal of Physiology, EarlyView.
Abstract figure legend β‐Hydroxy‐β‐methylbutyrate (HMB) enhances fast‐twitch muscle and mitochondrial function in D2.mdx mice. Male DBA/2J (wild‐type) and D2.mdx mice aged 3 or 6 months received daily β‐hydroxy‐β‐methylbutyrate (HMB; 1 mg g−1 day−1) via drinking water for 8 weeks. Fast‐twitch extensor digitorum longus (EDL) and slow‐twitch soleus (SOL)
