Optimized Monothiol Thioredoxin Derivative (ORP100S) Protects In Vitro and In Vivo from Radiation and Chemotoxicity Without Promoting Tumor Proliferation

open access: yesAdvanced Science, EarlyView.
Native thioredoxin‐1 (TRX) stimulates proliferation and rescues stem cells and cancer cells from multiple stressors by suppressing p53 and inhibiting ferroptosis via GPX4/SLC7A11 upregulation mediated by enhanced KLF4 expression and p53 promoter binding.

Snord15b Maintains Stemness of Intestinal Stem Cells via Enhancement of Alternative Splicing of Btrc Short Isoform for Suppression of β‐Catenin Ubiquitination

open access: yesAdvanced Science, EarlyView.
In intestinal stem cells (ISCs), Snord15b associates with Ilf2 to recruit splicing factors for alternative splicing of Btrc mRNA, leading to the generation of short Btrc. This short Btrc fails to form a functional E3 ubiquitin ligase complex for β‐catenin ubiquitination and degradation.

Sympathetic Activation Promotes Kidney Fibrosis in Mice via Macrophage‐Derived N2ICD‐Enriched Extracellular Vesicles

open access: yesAdvanced Science, EarlyView.
Norepinephrine/α2B‐adrenoceptor axis promotes the secretion of Notch2 intracellular domain (N2ICD)‐enriched extracellular vesicles (EVs) from macrophages. These EVs deliver N2ICD into fibroblasts, thereby inducing their activation. Deletion of Notch2 or α2B‐AR in macrophages disrupts N2ICD‐enriched EV formation and alleviates kidney fibrosis in mice ...

Lactylation of HMGB1 at K177 Drives Nuclear Export of TIAR to Promote Hypoxia‐Induced Stress Granule Formation

open access: yesAdvanced Science, EarlyView.
This study uncovers a novel mechanism in which p300‑catalyzed lactylation of HMGB1 triggers nuclear export of the HMGB1‐TIAR complex, driving TIAR‐dependent SGs formation in the cytoplasm. Mass spectrometry and mutagenesis reveals that K177 lactylation is essential for this export and subsequent SGs formation.

Restoring Histone Acetylation Accelerates Diabetic Wound Repair by Improving the Spatiotemporal Dynamics of Macrophages

open access: yesAdvanced Science, EarlyView.
Butyrate—via epigenetic modulation of the histone core—rebalance dysregulated macrophage function and promotes wound healing under persisting hostile conditions of diabetic mice. Additionally, butyrate harmonizes macrophage interactions with keratinocytes and fibroblasts as well as breaks the vicious cycle of inflammation in chronic wounds by restoring
