Alternate Day Fasting Enhances Intestinal Epithelial Function During Aging by Regulating Mitochondrial Metabolism

Aging Cell, EarlyView.
Alternate day fasting alleviates aging‐induced intestinal epithelial barrier damage by regulating mitochondrial metabolism in small intestinal stem cells. ABSTRACT With advancing age, the decline in intestinal stem cell (ISC) function can lead to a series of degenerative changes in the intestinal epithelium, a critical factor that increases the risk of

VDAC1‐Targeted NHK1 Peptide Recovers Mitochondrial Dysfunction Counteracting Amyloid‐β Oligomers Toxicity in Alzheimer's Disease

Aging Cell, EarlyView.
Amyloid‐β (Aβ) oligomers affect VDAC1 electrophysiology and the physiological metabolic cross‐talk between cytosol and mitochondria. The use of a small, synthetic VDAC1‐antagonist peptide, derived from hexokinase, restores mitochondrial functionality, and respiration in cellular models of Alzheimer's disease. ABSTRACT Mitochondrial dysfunction has been

SGLT2 Inhibition by Enavogliflozin Significantly Reduces Aβ Pathology and Restores Cognitive Function via Upregulation of Microglial AMPK Signaling in 5XFAD Mouse Model of Alzheimer's Disease

Aging Cell, EarlyView.
SGLT2 inhibition with Enavogliflozin significantly improves cognitive function and reduces Aβ pathology in the 5XFAD mouse model of Alzheimer's disease. Through AMPK activation, Enavogliflozin enhances microglial mitochondrial function and Aβ phagocytosis while reducing neuroinflammation.

Nervonic acid, a long chain monounsaturated fatty acid, improves mitochondrial function in adrenomyeloneuropathy fibroblasts

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Nervonic acid plays a vital role in maintaining normal brain and neuronal function. Nervonic acid has gained increasing attention because of its potential neuroprotective and anti‐inflammatory properties. Nonetheless, the beneficial effects of nervonic acid are yet to be fully investigated. Adrenomyeloneuropathy (AMN), a

D‐amino acid oxidase as a chemogenetic tool for spatiotemporally controlled hydrogen peroxide production: The oxygen connection

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose D‐amino acid oxidase (DAO) has been developed as a chemogenetic tool, to precisely manipulate redox levels in tissues and cells by generating H2O2 in the presence of D‐amino acids. The enzyme's significant oxygen consumption during H2O2 production may influence cellular oxygen levels.

Comparative Analysis of the Therapeutic Potential of Extracellular Vesicles Secreted by Aged and Young Bone Marrow‐Derived Mesenchymal Stem Cells in Osteoarthritis Pathogenesis

Cell Proliferation, Volume 58, Issue 4, April 2025.
Extracellular vesicles (EVs) from young and older donors share phenotypic similarities, but age significantly impacts their therapeutic effects in osteoarthritis (OA) management. EVs from younger donors not only display superior chondroprotective capabilities and more effectively mitigate cellular senescence in vitro, but also enhance in vivo efficacy ...

Mitochondrial Mutation Leads to Cardiomyocyte Hypertrophy by Disruption of Mitochondria‐Associated ER Membrane

Cell Proliferation, EarlyView.
Cardiomyocytes with high m.3243A>G burden exhibited hypertrophic phenotype. Mitochondria dysfunction occurred and tended to become round in cardiomyocytes with high m.3243A>G burden. Mitochondria‐associated ER membrane (MAM) was disrupted in cardiomyocytes with high m.3243A>G burden.

Glutaminase‐1 Mediated Glutaminolysis to Glutathione Synthesis Maintains Redox Homeostasis and Modulates Ferroptosis Sensitivity in Cancer Cells

Cell Proliferation, EarlyView.
GLS1‐mediated glutaminolysis supports GSH synthesis in cancer cells. GLS1 KO increases ROS, downregulates GPX4, and upregulates GPX1, making cells more sensitive to ferroptosis. Combining GLS1 or GPX1 inhibitors with a GPX4 inhibitor synergistically suppresses cancer growth.

Amelioration of signaling deficits underlying metabolic shortfall in TREM2R47H human iPSC‐derived microglia

The FEBS Journal, Volume 292, Issue 7, Page 1743-1762, April 2025.
The microglial receptor TREM2 is required for microglia responses in neurodegeneration, and the loss‐of‐function mutation R47H results in functional deficits linked to metabolism. Using human TREM2R47H or TREM2−/− microglia we show that supplementation with either citrate or succinate ameliorates microglia deficiencies due to TREM2 deficiency ...

Succinate receptor 1 signaling mutually depends on subcellular localization and cellular metabolism

The FEBS Journal, Volume 292, Issue 8, Page 2017-2050, April 2025.
SUCNR1, activated by succinate, is a Gi‐ and Gq‐coupled receptor present at the plasma membrane and in endosomes. There are conflicting reports about the pro‐/anti‐inflammatory effects of the succinate‐SUCNR1 signaling axis, and these are likely due to localization‐dependent signaling.
