Aminoglycoside-driven biosynthesis of selenium-deficient Selenoprotein P [PDF]

, 2017
Selenoprotein biosynthesis relies on the co-translational insertion of selenocysteine in response to UGA codons. Aminoglycoside antibiotics interfere with ribosomal function and may cause codon misreading.

MVP Inhibits Influenza A Virus‐Induced Ferroptosis by Targeting IRF1 and Increasing FSP1 Activity

Advanced Science, EarlyView.
During IAV infection, MVP inhibits IRF1 polyubiquitination, thereby relieving IRF1‐mediated transcriptional inhibition of FSP1. Consequently, this leads to an upregulation of FSP1 expression, thereby reinforcing the inhibition of ferroptosis. In addition, the MVP can promote myristoylation and ubiquitination of FSP1, enabling its membrane localization ...

Macrophage Extracellular Traps in Immunity and Cancer

Advanced Science, EarlyView.
As a macrophage‐mediated innate defense mechanism, the dysregulated release of METs drives chronic inflammation and influences tumor progression. Furthermore, METs exhibit a functional duality within the tumor microenvironment, capable of both promoting and suppressing tumor development.

Protective role of seleno-amino acid against IBD via ferroptosis inhibition in enteral nutrition therapy

iScience
Summary: The interplay between intestinal barrier degradation and trace element insufficiency worsens inflammatory bowel disease (IBD). Selenium (se) is essential for glutathione peroxidase 4 (GPX4) synthesis, which protects against intestinal epithelial

Midbrain dopamine oxidation links ubiquitination of glutathione peroxidase 4 to ferroptosis of dopaminergic neurons

The Journal of Clinical Investigation, 2023
Parkinson’s disease (PD) is a neurodegenerative disorder characterized by the gradual loss of midbrain dopaminergic neurons in association with aggregation of α-synuclein. Oxidative damage has been widely implicated in this disease, though the mechanisms

AML‐Targeted Metal‐Polyphenol Nanoplatform Induces Ferroptosis‐ICD Cascade for Antitumor Immunity Boosting

Advanced Science, EarlyView.
Schematic illustration of the synthesis protocol for Fe‐SH@Fn, an AML‐targeted nanoplatform engineered to co‐deliver shikonin (SH) and Fe3+, synergistically boosting antitumor immunity via ferroptosis induction and immunogenic cell death (ICD). ABSTRACT Acute myeloid leukemia (AML) remains a therapeutic challenge due to its low immunogenicity and ...

Microglial Membranes Wrapped Ultrasmall Medium‐Entropy Ru Single‐Atom Nanozyme: Enhanced Catalysis for Accelerating Inflammation/Redox Microenvironment Regulation in Intracerebral Hemorrhage

Advanced Science, EarlyView.
PtRhIr/Ru SAN@M nanozymes cross the blood–brain barrier and selectively accumulate in hemorrhagic brain regions. By mimicking multiple enzyme activities, they attenuate oxidative stress, modulate microglial polarization toward an anti‐inflammatory phenotype, inhibit ferroptosis, and promote neuronal repair.

Biomimetic Nanoplatform for Targeted Glioblastoma Therapy via Concurrently Triggering GPX4/DHODH Mediated Ferroptosis

Advanced Science, EarlyView.
Considering the great challenge in Glioblastoma multiforme (GBM) treatment, the authors designed and synthesized a multifunctional nanoplatform that effectively induced ferroptosis by synergetically inhibiting intrinsic intrisinc anti‐ferroptosis proteins, GPX4 & DHODH, and realized excellent in vitro and in vivo anti‐GBM effect.
