Mesenchymal stem cell-derived exosomal miR-26a induces ferroptosis, suppresses hepatic stellate cell activation, and ameliorates liver fibrosis by modulating SLC7A11

Open Medicine
Liver fibrosis is a key contributor to hepatic disease-related mortality. Exosomes derived from mesenchymal stem cells (MSCs) have been revealed to improve liver fibrosis.

Magneto‐NIR‐II‐Programmed Cascade Nanozymes Unlocking Blood–Brain Barrier Translocation and Autophagic Resistance in Glioblastoma

Advanced Science, EarlyView.
Magneto‐NIR‐II‐programmed NFSH nanozymes integrate magnetic blood–brain barrier (BBB) translocation, CD44 targeting, multimodal imaging, and cascade catalytic therapy for glioblastoma. Alternating magnetic fields and NIR‐II irradiation amplify ferroptosis, release H2S, suppress autophagic and mitophagic repair, and reshape the immune microenvironment ...

SLC7A11 in Fibrosis: Molecular Mechanisms and Future Prospects

aging and disease
Solute carrier family 7 member 11 (SLC7A11), or xCT, is a cystine-glutamate antiporter crucial for maintaining cellular antioxidant capacity through the uptake of cystine, which is vital for glutathione synthesis. This protein plays an important role in regulating ferroptosis, an iron-dependent form of cell death.

Kidney‐Targeted Cilastatin Nanoparticles Inhibit DPEP1‐Mediated Ferroptosis for Acute Kidney Injury Therapy

Advanced Science, EarlyView.
In this study, MPDA NPs were engineered to encapsulate CTT. To further increase renal accumulation of CTT, L‐serine was conjugated to the surface of the MPDA nanoparticles (CTT/MPDA@L‐Ser NPs). CTT/MPDA@L‐Ser NPs inhibit DPEP1 activity, thereby restoring ferroptosis defense mechanisms through upregulation of GPX4 and SLC7A11 expression, ultimately ...

CIRBP Stabilizes Slc7a11 mRNA to Sustain the SLC7A11/GPX4 Antioxidant Axis and Limit Ferroptosis in Doxorubicin-Induced Cardiotoxicity

Antioxidants
Doxorubicin-induced cardiotoxicity (DIC) significantly constrains the clinical efficacy of anthracycline chemotherapy, primarily through the induction of ferroptosis, an iron-dependent, regulated cell death driven by oxidative stress and lipid peroxidation. However, the upstream regulators of ferroptosis in DIC remain incompletely defined.

SPARC Drives Podocyte Mitochondrial Damage and Ferroptosis in Diabetic Kidney Disease Following Klotho Deficiency

Advanced Science, EarlyView.
Klotho deficiency promotes podocyte mitochondrial dysfunction and ferroptosis through activation of the PKCα/CUX1/SPARC/TGFβ‐RII axis. SPARC emerges as a key mediator linking Klotho loss to podocyte injury in DKD and other kidney injury models, suggesting broader implications for CKD progression.

Dual‐Gene Edited Extracellular Vesicles Remodel the Redox Homeostasis to Inhibit Ferroptosis in Intervertebral Disc Degeneration

Advanced Science, EarlyView.
ABSTRACT Intervertebral disc degeneration (IDD) is driven by ferroptosis of nucleus pulposus cells (NPCs) as a core pathological mechanism. Nucleus pulposus progenitor cells (NPPCs), exhibiting stem cell‐like properties, yield extracellular vesicles (PEVs) with high affinity for NPCs and enable targeted phenotypic regulation.

Targeting the PHB2–ACSL3 Lipid‐Remodeling Axis Overcomes Cisplatin Resistance by Restoring Ferroptosis in Gastric Cancer

Advanced Science, EarlyView.
ABSTRACT Platinum‐based chemotherapy resistance remains a major obstacle in gastric cancer (GC) treatment. Through integrated transcriptomic profiling of cisplatin‐resistant xenografts and pharmacogenomic interrogation of the NCI‐60 dataset, we identified Prohibitin‐2 (PHB2) as a previously unrecognized determinant of chemoresistance.

Integrated O2 and H2 Gas Therapy via Microneedle‐Assisted Photocatalytic Water Splitting for Accelerating Diabetic Full‐Thickness Skin Wound Healing

Advanced Science, EarlyView.
A concept of integrated O2 and H2 gas therapy is achieved using a gas‐producing material. PMP nanoparticles, fabricated from platinum, MIL‐101(Fe)‐NH2, and phosphotungstic acid, are integrated into bilayer gelatin methacryloyl microneedles for transdermal delivery. These microneedles enable integrated O2 and H2 gas therapy and promote wound healing via
