Phase Separation of NFIB Suppresses SLC3A2‐Mediated Ferroptosis in Castration‐Resistant Prostate Cancer

Advanced Science, EarlyView.
Castration‐resistant prostate cancer (CRPC) remains sensitive to ferroptosis, but its intrinsic resistance is poorly understood. Here, we identify NFIB as a master suppressor. SIRT7‐mediated NFIB acetylation drives its liquid–liquid phase separation, which promotes SLC3A2 transcription to inhibit ferroptosis.

Cuproptosis and Disulfidptosis Converge to Empower PD‐L1 Checkpoint Therapy via Cadict‐Induced PD‐L1 Translation

Advanced Science, EarlyView.
This study introduces Cadict, an EGFR‐targeted nanodrug that co‐delivers cuproptosis and disulfidptosis inducers to overcome immune resistance. Cadict synergistically enhances tumor cytotoxicity and sensitizes cancers to ICIs by upregulating PD‐L1 via an Eif5b‐dependent translation mechanism, fostering a potent antitumor immune response and ...

Atypical onset of nephropathic infantile cystinosis in a Russian patient with rare CTNS mutation

Clinical Case Reports, 2018
Key Clinical Message We report a Russian patient with atypical onset of infantile nephropathic cystinosis. The disease debuted with vomiting and loss of weight and motor skills. Nephropathic changes appeared 6 months after onset of disease.

Coenzyme A mitigates cystine-deprivation-induced ferroptosis by suppressing the iron-starvation response. [PDF]

FEBS J
Cystine (Cys2) deprivation in pancreatic cancer cells induces oxidative stress that destabilizes cytosolic iron–sulfur cluster (ISC) proteins, triggering an iron‐regulatory protein (IRP)‐mediated iron‐starvation response (ISR). This leads to increased iron uptake (via TFRC), an expanded labile iron pool, and ferroptosis.

Inhibition of Calcium‐Dependent Lipid Droplets Relocation of ACSL4‐PKCβ‐ALOX15 Complex Alleviates Ferroptosis and Acute Pancreatitis

Advanced Science, EarlyView.
This study identifies L‐type calcium channel blockers as novel ferroptosis inhibitors. It reveals that PKCβ, activated in calcium dependent manner, phosphorylates and activates ACSL4 and ALOX15, relocating them to lipid droplets to promote lethal lipid peroxidation and ferroptosis.

The Mechanism and Regulation of Disulfidptosis and Its Role in Disease

Biomedicines
Disulfidptosis is a recently identified form of regulatory cell death (RCD), Which has emerged as a research hotspot due to its distinctive feature of accumulating protein disulfide bonds, setting it apart from other RCD mechanisms.

Disulfide‐Bridged Ru Complex–Mediated Photo‐Disulfidptosis for Colorectal Cancer Therapy

Advanced Science, EarlyView.
In this work, a binuclear ruthenium complex, RuSSRu was developed for efficient colorectal cancer (CRC) treatment. The synergistic interaction between disulfidptosis and lysosomal damage‐induced apoptosis induced by RuSSRu amplified tumor cell death. This innovative approach offers a potent therapeutic strategy for CRC.

Multiple Disulfide-Bonded States of Native Proteins: Estimate of Number Using Probabilities of Disulfide Bond Formation

Molecules, 2020
The polypeptide backbone of proteins is held together by two main types of covalent bonds: the peptide bonds that link the amino acid residues and the disulfide bonds that link pairs of cysteine amino acids. Disulfide bonds form as a protein folds in the

Neuroprotective Effects of Time‐Restricted Feeding Combined With Different Protein Sources in MPTP‐Induced Parkinson's Disease Mice Model and Its Modulatory Impact on Gut Microbiota Metabolism

Advanced Science, EarlyView.
Time‐restricted feeding (TRF) exerts protein‐dependent neuroprotective effects in an MPTP‐induced Parkinson's disease model. In casein‐fed mice, TRF improves gut barrier integrity and reduces neuroinflammation, possibly via modulation of Allobaculum and BCAAs.

p53 Suppresses Metabolic Stress-Induced Ferroptosis in Cancer Cells

Cell Reports, 2018
How cancer cells respond to nutrient deprivation remains poorly understood. In certain cancer cells, deprivation of cystine induces a non-apoptotic, iron-dependent form of cell death termed ferroptosis.
