Drp1 acetylation mediated by CDK5-AMPK-GCN5L1 axis promotes cerebral ischemic injury via facilitating mitochondrial fission

Molecular Medicine
The aberrant acetylation of mitochondrial proteins is involved in the pathogenesis of multiple diseases including neurodegenerative diseases and cerebral ischemic injury.

Raptor and Drp1 Function Synthetically to Control Hypoxic Death and the Mitochondrial Network in Caenorhabditis elegans

The FASEB Journal, Volume 40, Issue 13, 15 July 2026.
Hypoxia results in fragmented mitochondria. Whether this fragmentation promotes or prevents cell death is unresolved. Caenorhabditis elegans mutants defective in mitochondrial fission and fusion coupled with a hypoxia resistant Raptor mutant demonstrated that hypoxia‐induced mitochondrial fragmentation occurs without an intact fission machinery and ...

Advances in the Core Role and Mechanisms of Mitochondrial Dysfunction in Alzheimer's Disease

Brain and Behavior, Volume 16, Issue 7, July 2026.
In Alzheimer's disease, Aβ and Tau trigger mitochondrial dysfunction, driving a pathological cascade that results in cognitive decline. Gut microbiota dysbiosis exacerbates this via the gut–brain axis, making mitochondria a key therapeutic target. ABSTRACT Introduction Alzheimer's disease (AD) is a complex neurodegenerative disorder whose pathogenesis ...

EGR1 Mediates Ursodeoxycholic Acid‐Promoted Mitophagy to Prevent Postovulatory Aging of Porcine Oocytes

Aging Cell, Volume 25, Issue 7, July 2026.
This study delivers dual key advances: mechanistically, we uncover a novel role of EGR1 as a pivotal transcriptional regulator that bridges upstream gene expression dysregulation to downstream mitophagic decline in oocyte aging; and translationally, we validate the therapeutic potential of the clinical drug UDCA to counteract oocyte aging.

P110 Inhibits DRP1/FIS1-Mediated Mitochondrial Fission to Alleviate Uric Acid–Induced Apoptosis in HK-2 Cells

Frontiers in Bioscience-Landmark
Background: Hyperuricemic nephropathy is associated with mitochondrial dysfunction. Dynamin-related protein 1 (DRP1), a key regulator of mitochondrial fission, is activated under stress and translocates to the mitochondria, where it ...

A Non‐Canonical Role for Hepatocyte MLKL in Promoting Mitochondrial Dysfunction and Senescence in the Aging Liver

Aging Cell, Volume 25, Issue 7, July 2026.
Aging‐associated MLKL upregulation in hepatocytes induces mitochondrial dysfunction and oxidative stress, accompanied by increased release of pro‐inflammatory extracellular vesicles. These changes are associated with increased p16+/p21+ senescence in hepatocytes and non‐parenchymal cells (macrophages, stellate cells, and endothelial cells), suggesting ...

Metabolic Kinases as Regulators of Inter‐Organelle Communication in Aging and Age‐Related Diseases

Aging Cell, Volume 25, Issue 7, July 2026.
Metabolic kinases integrate cellular energy, nutrient, and stress signals to regulate inter‐organelle coordination during aging. In young or healthy cells, coordinated communication among mitochondria, the endoplasmic reticulum, lysosomes, peroxisomes, and the Golgi apparatus supports calcium handling, lipid metabolism, mitochondrial dynamics ...
