Redox‐regulated signalling of adaptations to contractile activity in skeletal muscle: Implications for age‐related muscle weakness

Experimental Physiology, EarlyView.
Abstract Skeletal muscle adaptation to contractile activity is modulated by redox signalling, primarily through reactive oxygen species (ROS) such as hydrogen peroxide (H2O2). Early research framed ROS as deleterious byproducts of exercise, but subsequent studies have established their roles as signalling molecules involved in mitochondrial biogenesis,

Peroxiredoxins in Regulation of MAPK Signalling Pathways; Sensors and Barriers to Signal Transduction

Molecules and Cells, 2016
Peroxiredoxins are highly conserved and abundant peroxidases. Although the thioredoxin peroxidase activity of peroxiredoxin (Prx) is important to maintain low levels of endogenous hydrogen peroxide, Prx have also been shown to promote hydrogen peroxide ...

A method for detection of overoxidation of cysteines: peroxiredoxins are oxidized in vivo at the active-site cysteine during oxidative stress

, 2002
Peroxiredoxins are often encountered as double spots when analysed by two-dimensional electrophoresis. The quantitative balance between these two spots depends on the physiological conditions, and is altered in favour of the acidic variant by oxidative ...

A comprehensive analysis of the peroxiredoxin reduction system in the Cyanobacterium Synechocystis sp. strain PCC 6803 reveals that all five peroxiredoxins are thioredoxin dependent [PDF]

, 2009
Cyanobacteria perform oxygenic photosynthesis, which gives rise to the continuous production of reactive oxygen species, such as superoxide anion radicals and hydrogen peroxide, particularly under unfavorable growth conditions.

Neuroprotective roles of klotho: Molecular pathways and therapeutic implications for cognitive health in neurological and psychiatric diseases

Experimental Physiology, EarlyView.
Abstract Klotho, a pleiotropic protein initially identified for its role in kidney function, has garnered significant attention for its neuroprotective properties in various neurodegenerative diseases. It regulates key processes, such as oxidative stress, neuroinflammation, synaptic plasticity and myelination, all crucial for maintaining neuronal ...

Research progress on damage ⁃ associated molecular patterns in intracerebral hemorrhage

Chinese Journal of Contemporary Neurology and Neurosurgery, 2021
After the onset of intracerebral hemorrhage (ICH), the immune storm causes the massive death of neurons and their supporting cells. Cytotoxic substances such as hemoglobin, heme and iron ions released by red blood cells lysis also promote death of ...

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

The Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session

Born early, age fast: Consequences of premature birth on chronic disease and accelerated ageing

The Journal of Physiology, EarlyView.
Abstract figure legend ELGANs are exposed to several postnatal pro‐oxidant stressors, including ambient and supplemental oxygen, mechanical ventilation, infections, hyperalimentation, excessive glucocorticoids and intermittent hypoxia. Since endogenous antioxidant defences are underdeveloped, this imbalance promotes oxidative stress and inflammation ...

Peroxiredoxins as cellular guardians in Sulfolobus solfataricus characterization of Bcp1, Bcp3 and Bcp4.

, 2008
Peroxiredoxins are ubiquitous enzymes that are part of the oxidative stress defense system. In the present study, we identified three peroxiredoxins [bacterioferritin comigratory protein (Bcp)1, Bcp3 and Bcp4] in the genome of the aerobic ...

Excessive training does not induce mitochondrial dysfunction or impair insulin signalling within skeletal muscle

The Journal of Physiology, EarlyView.
Abstract figure legend Three weeks of overtraining in trained endurance athletes reduced exercise performance without impairing glucose tolerance. In skeletal muscle, overtraining was associated with increased expression of lipid metabolism‐related proteins, enhanced mitochondrial biogenesis and preserved insulin signalling, despite elevated oxidative ...
