Angiotensin‐converting enzyme and exercise adaptations: Genetic variability, pharmacological modulation and future directions

The Journal of Physiology, EarlyView.
Abstract figure legend ACE I/D genotype, enzyme activity and integrated physiological adaptations. Upper panel: Conceptual framework linking the ACE I/D polymorphism (left) with circulating/tissue ACE activity (centre; violin plots based on hypothetical data for illustration) and strength/power versus endurance phenotypes (right).

Hypoxia and hypercapnia elicit overlapping but distinct skeletal muscle toxicities

The 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 ...

Amyloid β alters vascular CaV1.2 channel spatiotemporal properties

The Journal of Physiology, EarlyView.
Abstract figure legend Amyloid‐β1‐42 (Aβ1‐42) triggers a male‐specific signalling cascade influencing CaV1.2 spatiotemporal properties in cerebral vascular smooth muscle. The signalling pathway involves NADPH oxidase (NOX)‐derived reactive oxygen species (ROS) activation of protein kinase C (PKC). Aβ1‐42 can also activate protein kinase A (PKA).

NSAID ingestion augments training‐induced muscle hypertrophy and differentially affects muscle mRNA expression, but not strength gains, in trained men

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic outlining the impact of NSAID ingestion on resistance exercise training‐induced changes in muscle morphology, function and gene networks relative to placebo ingestion in trained males. Abstract Non‐steroidal anti‐inflammatory drugs (NSAIDs) are widely overused in sports.

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.

Coordinated regulation of PIEZO2 by alternative splicing, post‐translational modification, membrane trafficking and protein partners

The Journal of Physiology, EarlyView.
Abstract figure legend Regulatory mechanisms such as alternative splicing, post‐translational modification, membrane trafficking, and protein interactions control channel gating, membrane abundance, and overall activity of PIEZO2. Proper regulation supports PIEZO2‐dependent proprioceptive, somatosensory, nociceptive, pruriceptive and interoceptive ...

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.

Voltage‐gated potassium channels mediate thyroid hormone control of skeletal muscle excitability

The Journal of Physiology, EarlyView.
Abstract figure legend Thyroid hormone (TH)‐dependent remodelling of potassium (K+) channel networks regulates skeletal muscle (SkM) excitability. Triiodothyronine (T3), locally generated from thyroxine (T4) by type 2 deiodinase (D2), binds thyroid hormone receptors (TRα/β) and modulates transcription via thyroid response elements (TREs).

CaV1.2 dynamics in native male arterial myocytes

The Journal of Physiology, EarlyView.
Abstract figure legend Proposed model of microtubule‐dependent CaV1.2 reorganization in vascular disease. Schematic illustration of microtubule‐mediated delivery and stabilization of CaV1.2 channels into enlarged plasma membrane clusters in response to Ang II or hyperglycaemia, promoting cooperative gating and enhanced Ca2+ influx. Abstract L‐type CaV1.
