Involvement of sperm acetylated histones and the nuclear isoform of Glutathione peroxidase 4 in fertilization [PDF]

open access: yes, 2017
We previously demonstrated that the nuclear form of Glutathione peroxidase 4 (nGPx4) has a peculiar distribution in sperm head, being localized to nuclear matrix and acrosome and that sperm lacking nGPx4 are more prone to decondensation in vitro. In this

NIR‐Activatable Domino Cascade Catalysis Nanozyme Reactor for Multi‐Mechanism Synergistic Immunotherapy in Bladder Cancer

open access: yesAdvanced Science, EarlyView.
This study presents an intravesical delivery strategy of ferroptosis‐ and immunity‐inducing nanozyme‐loaded thermoresponsive hydrogels (FMCC@PNH) for enhanced bladder cancer therapy. Abstract Current intravesical therapies for bladder cancer after resection are limited by poor tissue penetration, off‐target effects, and insufficient efficacy.

The mutualistic fungus Piriformospora indica protects barley roots from a loss of antioxidant capacity caused by the necrotrophic pathogen Fusarium culmorum [PDF]

open access: yes, 2013
Fusarium culmorum causes root rot in barley (Hordeum vulgare), resulting in severely reduced plant growth and yield. Pretreatment of roots with chlamydospores of the mutualistic root-colonizing basidiomycete Piriformospora indica (Agaricomycotina ...

Chloroplast Stress Signals Orchestrate Epidermis‐Specific Remodeling of Mitochondria and ER Under High Light

open access: yesAdvanced Science, EarlyView.
High light exposure triggers an epidermis‐specific remodeling of mitochondria and ER in Arabidopsis, driven by chloroplast‐derived signals. Live‐cell imaging shows that HL rapidly suppresses mitochondrial motility, followed by fusion‐driven elongation and ER cisternal expansion.

Ablation of ferroptosis regulator glutathione peroxidase 4 in forebrain neurons promotes cognitive impairment and neurodegeneration

open access: yesRedox Biology, 2017
Synaptic loss and neuron death are the underlying cause of neurodegenerative diseases such as Alzheimer's disease (AD); however, the modalities of cell death in those diseases remain unclear. Ferroptosis, a newly identified oxidative cell death mechanism

Ochratoxin A: In Utero Exposure in Mice Induces Adducts in Testicular DNA [PDF]

open access: yes, 2010
Ochratoxin A (OTA) is a nephrotoxin and carcinogen that is associated with Balkan endemic nephropathy and urinary tract tumors. OTA crosses the placenta and causes adducts in the liver and kidney DNA of newborns.

NuSAP Safeguards Centriole Integrity to Mediate CEP57‐CEP152 Torus Recruitment for Proper Engagement

open access: yesAdvanced Science, EarlyView.
This study reveals a novel role for the microtubule stabilizer NuSAP at centrioles. NuSAP depletion destabilizes the centriole's tubulin structure, causing premature disengagement, PCM defects, and mis‐localization of the CEP57‐CEP63‐CEP152 complex. By reinforcing centriole architecture, NuSAP enables early CEP57 loading and initiates a newly proposed ...

PRDM1+ Malignant Cells Mediate an Immunosuppressive Landscape and Resistance to Neoadjuvant Chemoradiotherapy and Immunotherapy in Esophageal Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
Integrated scRNA‐seq, scTCR‐seq analysis, and functional assays identify PRDM1+ malignant epithelial cells with hyper lipid peroxidation characteristics that demonstrate reduced responsiveness to the nICRT treatment. Principal factor PRDM1 activates cysteine metabolism genes to modulate lipid peroxidation (an intrinsic cellular pathway related to ...

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

open access: yesAdvanced 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.
