Suppression of mitochondrial respiration through recruitment of p160 myb binding protein to PGC-1α : modulation by p38 MAPK [PDF]

, 2004
The transcriptional coactivator PPAR gamma coactivator 1 α (PGC-1α) is a key regulator of metabolic processes such as mitochondrial biogenesis and respiration in muscle and gluconeogenesis in liver. Reduced levels of PGC-1α in humans have been associated

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 ...

Pex13 Mutant Mice as Models for the Peroxisome Biogenesis Disorders

, 2008
Zellweger syndrome (ZS) is the most severe form of a spectrum of disorders resulting from mutations in PEX genes, genes that encode proteins necessary for peroxisome biogenesis.

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 ...

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 ...

Investigations of peroxisome membrane complexity and biogenesis [PDF]

, 2020
Eukaryotic life is distinguished by compartmentalizing biochemical reactions in membrane-delimited organelles, and how organelles accomplish this sequestration is a fundamental question of cell biology.

The Health Benefits of Exercise: Molecular and Cellular Mechanisms. [PDF]

MedComm (2020)
Our synthesis integrates evidence on exercise‐induced regulatory mechanisms across multiple systems (musculoskeletal, cardiovascular, nervous, metabolic and immune), cross‐system, and aging. We also discusses adaptive regulation of exercise in extreme environments, along with the prospects and challenges of multiomics and AI‐driven precision exercise ...

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.
