Mitochondria‐Targeted Multimodal Nanotherapeutics Suppress Oxidized mtDNA‐Driven Inflammation at the Source

Advanced Science, EarlyView.
Ox‐mtDNA fragments escaping from mitochondria drive robust inflammatory responses. A targeted nanoplatform simultaneously inhibits mitochondrial FEN1‐mediated mtDNA cleavage and scavenges ROS, preventing the generation of immunogenic Ox‐mtDNA fragments. The released SeNPs further promote autophagic clearance of cytosolic mtDNA. Consequently, cGAS‐STING,

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Research Progress of Berberine in Kidney Disease: Targeting Mitochondria and Ferroptosis

iNew Medicine, EarlyView.
This figure illustrates the model‐specific renoprotective mechanisms of berberine (BBR) across three major kidney diseases. From left to right, the diagram shows that BBR targets distinct core pathways depending on the pathological context: in diabetic nephropathy (DN), BBR activates AMPK to improve mitochondrial energy metabolism; in acute kidney ...

Lewy bodies are surrounded by granulovacuolar degeneration bodies in dementia with Lewy bodies

Brain Pathology, EarlyView.
Here, we report Lewy bodies (LBs) to be enriched for tau‐laden granulovacuolar degeneration bodies (GVBs), suggesting a potential mechanistic interface between α‐synuclein and tau pathology in dementia with Lewy bodies (DLB). Abstract Lewy bodies (LBs), composed primarily of aggregated α‐synuclein (α‐syn), are the pathological hallmark of Lewy body ...

Reactive oxygen species, antioxidants and the regulation of plant development

The FEBS Journal, EarlyView.
The regulation of axillary bud outgrowth by the interplay between phytohormone and redox signals. Axillary bud outgrowth is regulated by cellular energy status and the balance between phytohormones, notably abscisic acid (ABA) and gibberellic acid (GA).

The role of glutamate release on voltage-dependent anion channels (VDAC)-mediated apoptosis in an eleven vessel occlusion model in rats. [PDF]

PLoS ONE, 2010
Voltage-dependent anion channel (VDAC) is the main protein in mitochondria-mediated apoptosis, and the modulation of VDAC may be induced by the excessive release of extracellular glutamate.

Predicting molecular mechanism of silymarin-potentiated diclofenac toxicity: Insight from in silico molecular docking

Toxicology Reports, 2023
Silymarin was shown to enhance diclofenac toxicity by inducing the loss of mitochondrial membrane permeability (MMP) in Caco-2 cells, independent of endoplasmic reticulum stress.

The mitochondrial‐targeted antioxidant SkQ1 prevents skeletal muscle mitochondrial‐apoptotic but not necroptotic signalling during ovarian cancer

The Journal of Physiology, EarlyView.
Abstract figure legend An evaluation of the degree to which mitochondrial hydrogen peroxide emission (mH2O2)‐mediated apoptotic and necroptotic signalling contributes to skeletal muscle atrophy in an orthotopic epithelial ovarian cancer (EOC) model. To determine whether attenuating mH2O2 could prevent regulated cell death signalling and mitigate muscle

Demonstration of beat‐to‐beat, on‐demand ATP synthesis in ventricular myocytes reveals sex‐specific mitochondrial and cytosolic dynamics

The Journal of Physiology, EarlyView.
Abstract figure legend Beat‐locked mitochondrial ATP transients reveal modular, sex‐specific bioenergetic control during excitation–contraction coupling. A, each action potential activates L‐type CaV1.2 channels, producing a Ca2+ influx that triggers ryanodine receptors (RyR2) and elicits SR Ca2+ release.

Dual mechanism of ion permeation through VDAC revealed with inorganic phosphate ions and phosphate metabolites. [PDF]

PLoS ONE, 2015
In the exchange of metabolites and ions between the mitochondrion and the cytosol, the voltage-dependent anion channel (VDAC) is a key element, as it forms the major transport pathway for these compounds through the mitochondrial outer membrane. Numerous
