TRIM56 Aggravates Cerebral Ischemia‐Reperfusion Injury via Inhibiting KLF4‐Activated Ferroptosis Signaling

open access: yesAdvanced Science, EarlyView.
This study reveals that the E3 ubiquitin ligase TRIM56 exacerbates neuronal ferroptosis and brain damage by mediating K48‐linked ubiquitination and degradation of KLF4, leading to suppression of the xCT/GSH/GPX4 axis. Targeting TRIM56 alleviates cerebral ischemia‐reperfusion injury in vivo and in vitro, highlighting its therapeutic potential.

TBK1 Induces the Formation of Optineurin Filaments That Condensate with Polyubiquitin and LC3 for Cargo Sequestration

open access: yesAdvanced Science, EarlyView.
Phosphorylation of Optineurin by TBK1 induces the formation of filaments that condensate upon binding to linear polyubiquitin. Membrane‐anchored LC3 partitions into these condensates, suggesting that phase separation of filamentous Optineurin with ubiquitylated cargo promotes the sequestration of cargo and its subsequent alignment with LC3‐positive ...

NAD⁺ Reduction in Glutamatergic Neurons Induces Lipid Catabolism and Neuroinflammation in the Brain via SARM1

open access: yesAdvanced Science, EarlyView.
NAD⁺ homeostasis maintains neuronal integrity through opposing actions of NMNAT2 and SARM1. Loss of NMNAT2 in glutamatergic neurons reprograms cortical metabolism from glucose to lipid catabolism, depletes lipid stores, and triggers inflammation and neurodegeneration.

TMEM131‐Mediated Soluble TRAIL Triggered Type II Alveolar Epithelial Cell Senescence in Radiation‐Induced Lung Injury

open access: yesAdvanced Science, EarlyView.
TMEM131 recruits the COPII complex to accelerate TRAIL transportation from endoplasmic reticulum to Golgi apparatus, and promotes soluble TRAIL secretion. TRAIL inhibits mitophagy and induces senescence through DR5 receptor in type II alveolar epithelial cells, ultimately driving radiation‐induced lung injury (RILI) progression.

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota

open access: yesAdvanced Science, EarlyView.
This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Lactylation‐Driven YTHDC1 Alleviates MASLD by Suppressing PTPN22‐Mediated Dephosphorylation of NLRP3

open access: yesAdvanced Science, EarlyView.
In MASLD, YTHDC1 undergoes increased lactylation and ubiquitination, reducing its expression. AARS1 mediates lactylation at lysine 565, while disrupted binding to LDHA further promotes lactylation, suppressing YTHDC1. This downregulation enhances PTPN22 mRNA stability, leading to NLRP3 dephosphorylation and activation, which exacerbates inflammation ...

CHB‐Induced Immune Zonation Chaos Elicited LXRα‐mediated Lipid Metabolism Disorders in Kupffer Cells to Induce Cancer Stem Cell Formation

open access: yesAdvanced Science, EarlyView.
By profiling the spatiotemporal hepatic landscape of CHB mouse models, the originally peri‐portal localized KCs migrated to the peri‐central in a CXCL9‐CXCR3‐dependent manner, facilitating their interaction with HBV+ hepatocytes. The interaction promoted LMD in KCs through ASGR1‐induced LXRα degradation, which, in turn, induced CSC formation via Stat3 ...
