Time‐Restricted Feeding Alters Behavior in a Sex‐Specific Manner in Mice With Neuropathic Pain

Molecular Nutrition &Food Research, Volume 70, Issue 8, 27 April 2026.
Time‐restricted feeding (TRF) alleviates anxiety‐like behavior in male mice with neuropathic pain (NP), but not in females. Upon nerve injury, TRF altered the diurnal expression of transcripts in the hypothalamus. These findings suggest that TRF should be explored as a new therapeutic approach to alleviate the comorbid anxiety in NP.

Nonoxidizable ubiquinol derivatives that are suitable for the study of the ubiquinol oxidation site in the cytochrome bc1 complex

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2002
Recent X-ray crystallographic analyses of the mitochondrial cytochrome bc1 complex show ubiquinone binding at the Q(i) site, but attempts to show binding of ubiquinol or ubiquinone at the Q(o) site have been unsuccessful, even though the binding of noncompetitive Q(o) site inhibitors near the putative ubiquinol binding pocket is well established.

Genomic and Transcriptomic Insights Into the Autotrophic Metabolism on H2 + CO2 or CO of the Thermophilic Acetogenic Model Organism Moorella thermoacetica

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Moorella thermoacetica is the model organism for elucidation of acetogenesis. The reduction of CO2 to acetate is well studied, but how redox carrier balancing and energy conservation are maintained during autotrophic growth and how H2 is oxidised remains enigmatic.

Role of Succinate Dehydrogenase in Age‐Related Th17 Inflammation

Aging Cell, Volume 25, Issue 4, April 2026.
Age‐induced mitoSTAT3‐dependent upregulation of mitochondrial complex II; succinate dehydrogenase (SDH), in CD4+ T cells promotes an imbalance in the levels of metabolites succinate and fumarate, characterized by lower succinate and higher fumarate. Changes in the metabolites alter mitochondrial structure and function and promote HIF1α to induce the ...

Pck1 Deficiency Drives Mitochondrial Dysfunction and Cellular Senescence in Adipocytes

Aging Cell, Volume 25, Issue 4, April 2026.
Phosphoenolpyruvate carboxykinase 1 (Pck1) expression is downregulated in aging white adipose tissue. Adipocyte Pck1 deficiency impairs TCA cycle cataplerosis, causing fumarate accumulation. Excess fumarate disrupts mitochondrial homeostasis, triggers oxidative stress and mtDNA release, activating cGAS–STING signaling and driving inflammaging ...

When Pathways Converge: Iron, Lipid Peroxidation, and α‐Synuclein in Ferroptosis‐Driven Dopaminergic Neurodegeneration

Journal of Neurochemistry, Volume 170, Issue 4, April 2026.
Dopaminergic neurons are particularly susceptible to ferroptosis. Pacemaking activity–driven calcium (Ca2+) influx increases metabolic demand and reactive oxygen species (ROS) production, promoting iron release from aconitase. Alpha‐synuclein (α‐syn) enhances iron uptake via transferrin receptor 1 (TfR1) and exhibits ferrireductase activity, converting

Identification of the alternative oxidase gene and its expression in the copepod Tigriopus californicus [PDF]

, 2019
In addition to the typical electron transport system (ETS) in animal mitochondria responsible for oxidative phosphorylation, in some species there exists an alternative oxidase (AOX) pathway capable of catalyzing the oxidation of ubiquinol and the ...
