Mitochondrial Ca2+ uniporter haploinsufficiency leads to sexually dimorphic redox imbalance and metabolic remodelling in the mouse brain

The Journal of Physiology, EarlyView.
Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...

Metabolic stimulation improves bioenergetics and haematologic indices of circulating erythrocytes from sickle cell mice

The Journal of Physiology, EarlyView.
Abstract figure legend Metabolic stimulation improves bioenergetics, redox state, hydration and hematologic indices of circulating erythrocytes from sickle cell mice. Retained mitochondria in circulating RBCs from sickle mice are a source of RBC ATP as mitochondria function (ETC, electron transport chain) inhibitors [rotenone, a mitochondrial complex I

Reduction of the plastoquinone pool by exogenous NADH and NADPH in higher plant chloroplasts. Characterization of a NAD(P)H-plastoquinone oxidoreductase activity

Biochimica et biophysica acta
Chlorophyll fluorescence measurements were performed on osmotically lysed potato chloroplasts in order to characterize the reactions involved in the dark reduction of photosynthetic inter-system chain electron carriers. Addition of NADH or NADPH to lysed chloroplasts increased the chlorophyll fluorescence level measured in the presence of a non-actinic

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

The Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

Vitamin‐Responsive Disorders: From Molecular Basis to Clinical Presentation and Therapy

Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Vitamin‐dependent cofactors are essential for numerous metabolic reactions, and defects affecting their uptake, conversion, utilisation, or regeneration constitute a heterogeneous group of inherited metabolic disorders (IMDs). Although dietary vitamin intake is sufficient to sustain coenzyme synthesis in healthy individuals, it is insufficient

Redox signals and oxidative stress in the control of mitochondrial protein import

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Mitochondrial protein import is essential for organelle biogenesis and cellular homeostasis. It operates in an environment that is intrinsically shaped by redox chemistry. Mitochondria are major sources of reactive oxygen species (ROS), which arise as by‐products of oxidative phosphorylation. Cells therefore maintain sophisticated ROS‐handling

Integrated genomic and transcriptomic approaches reveal oxidative stress adaptation mechanisms in a mesotrione‐resistant Amaranthus tuberculatus biotype

Pest Management Science, Volume 82, Issue 7, Page 6387-6398, July 2026.
Integrated GWAS and transcriptomics in a Canadian waterhemp biotype reveal mesotrione resistance is polygenic and metabolically driven. Significant SNPs and 187 herbicide‐responsive genes point to enhanced redox homeostasis, glutathione‐linked detoxification, lipid/secondary metabolism, and oxidative stress responses. Resistance arises from coordinated,

A multilayered regulatory framework linking cell wall remodelling, redox homeostasis, and metabolic plasticity during leaf development in Arabidopsis thaliana

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
This study proposes a three‐layered regulatory model illustrating the transition from cell wall remodelling to redox homeostasis during leaf maturation. The model integrates structural extensibility (CESA8, XTH15), redox‐metabolic balancing (AOX1A), and transcriptional feedback mediated by NAC13.

Comparative proteomics analysis of root and nodule mitochondria of soybean

Plant, Cell &Environment, Volume 49, Issue 7, Page 3482-3499, July 2026.
Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

Exercise Training Stimulates the Release of Glutathione Peroxidase 1 (GPX1)‐Enriched Extracellular Vesicles That Promote Angiogenesis

The FASEB Journal, Volume 40, Issue 12, 30 June 2026.
Exercise Training Stimulates the Release of Glutathione Peroxidase 1 (GPX1)‐Enriched Extracellular Vesicles that Promote Angiogenesis. The results from this study suggest that EVs isolated from blood immediately after the last bout of endurance exercise training (ExerV) are enriched in antioxidants. ExerVs stimulate vascular growth both in vitro and in
