Dietary interventions in acute kidney injury: From molecular mechanism to clinical trials

Experimental Physiology, EarlyView.
Abstract Ageing impairs renal resilience with an elevated risk of frequent and harmful acute kidney injury (AKI) that causes substantial morbidity and mortality among hospitalized patients. Since different damaging stimuli at the molecular, cellular and functional level contribute to this loss in kidney function, AKI's pathophysiology is heterogeneous ...

PEX16: a multifaceted regulator of peroxisome biogenesis

, 2013
Peroxisomes are formed by two distinct pathways: the growth and fission of mature peroxisomes and de novo synthesis at the endoplasmic reticulum (ER).

Mitophagy in skeletal muscle: Impact of ageing, exercise and disuse

Experimental Physiology, EarlyView.
Abstract Skeletal muscle plays an important role in whole‐body health, quality of life and regulation of metabolism. The maintenance of a healthy mitochondrial pool is imperative for the preservation of skeletal muscle quality and is mediated through mitochondrial quality control consisting of mitochondrial turnover mediated by a balance between ...

Genomic structure and identification of 11 novel mutations of the PEX6 (peroxisome assembly factor-2) gene in patients with peroxisome biogenesis disorders

, 1999
The PEX6 (peroxisome assembly factor-2, PAF-2) gene encodes a member of the AAA protein (ATPases associated with diverse cellular activities) family and restores peroxisome assembly in fibroblasts from peroxisome biogenesis disorder patients belonging to

The efficacy and physiological bases of small muscle mass exercise in health and disease

Experimental Physiology, EarlyView.
Abstract The conventional approach to aerobic exercise prescription involves large muscle mass exercise and the manipulation of variables such as training intensity, duration and frequency to promote desired adaptations. However, during whole‐body exercise, central limitations (i.e., neural, pulmonary and/or cardiac) constrain exercise tolerance and ...

Ageing alters cysteine oxidation‐regulated redox signalling in skeletal muscle: Integrative omics and AI‐based structural predictions

Experimental Physiology, EarlyView.
Abstract Ageing is associated with loss of skeletal muscle mass and strength (sarcopenia) and disrupted redox homeostasis. Redox signalling is essential for muscle adaptation, yet the mechanisms by which ageing disrupts cysteine‐based regulation are poorly defined. The drivers of site‐specific reactivity and signalling specificity in aged muscle remain

The cold‐water immersion recovery–adaptation paradox: Reconciling acute parasympathetic and analgesic benefits with chronic hypertrophy attenuation

Experimental Physiology, EarlyView.
Abstract Cold‐water immersion (CWI) is among the most widely used post‐exercise recovery modalities in elite sport and clinical rehabilitation, yet a fundamental paradox now emerges from the evidence: the same protocols that accelerate parasympathetic reactivation and reduce perceived muscle soreness also suppress the molecular and cellular machinery ...

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

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.

Pex1 loss-of-function in zebrafish is viable and recapitulates hallmarks of Zellweger spectrum disorders

Frontiers in Molecular Neuroscience
Zellweger spectrum disorders (ZSDs) are rare autosomal recessive conditions belonging to the larger group of peroxisome biogenesis disorders. The most prevalent form of ZSD is caused by mutations in the PEX1 gene, which encodes an AAA ATPase protein ...

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

The 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.
