The INAVA mRNA in Extracellular Vesicles Activates Normal Ovarian Fibroblasts by Phosphorylation–Ubiquitylation Crosstalk of HMGA2

open access: yesAdvanced Science, EarlyView.
Ovarian cancer‐derived extracellular vesicles (EVs) transfer INAVA mRNA to normal ovarian fibroblasts (NOFs). Translated INAVA protein inhibits HMGA2 phosphorylation‐dependent ubiquitylation and proteasomal degradation, promoting NOF activation.

Dynamic Cap‐Mediated Substrate Access and Potent Inhibitor Design of Monkeypox Virus I7L Protease

open access: yesAdvanced Science, EarlyView.
The first crystal structure of MPXV I7L protease, revealing its unique dimeric form is resolved. The structures and MD simulations uncovered a dynamic cap region that regulates substrate access to the active site. The structural basis of substrate recognition and the catalytic mechanism are elucidated, which led to the development of a FRET‐based assay

Potent Cross‐neutralizing Antibodies Reveal Vulnerabilities of Henipavirus Fusion Glycoprotein

open access: yesAdvanced Science, EarlyView.
Hendra and Nipah viruses (HNVs) pose significant threats to global health. This work reports potent cross‐neutralizing antibodies targeting the fusion glycoprotein (F) and reveals shared features of these antibodies and vulnerabilities of F, thereby guiding the rational design of countermeasures against HNVs and similar pathogens.

DDX3 Regulates the Cap‐Independent Translation of the Japanese Encephalitis Virus via Its Interactions with PABP1 and the Untranslated Regions of the Viral Genome

open access: yesAdvanced Science, EarlyView.
Japanese encephalitis virus (JEV) employs a cap‐independent (CI) translation strategy to evade host translational shutoff. During the shut‐off of host cellular canonical translation, DEAD‐box protein 3 (DDX3) bind to JEV UTRs to establish a closed‐loop architecture, and its interaction with poly(A)‐binding protein 1 (PABP1) to form DDX3/PABP1/eIF4G ...

Fast pH‐Driven Solubilization Method of Realgar (As4S4) to Reduce the Toxicity of Arsenic [As(III)] for Medicinal Purposes

open access: yesAdvanced Science, EarlyView.
Arsenic trioxide transformed acute promyelocytic leukemia therapy and shows promise against HIV. A new method to solubilize the mineral realgar produces different arsenic species depleting the main arsenic target, nuclear PML protein, and retaining effects on leukemic and HIV reservoir cells, while minimizing off‐target damage.

CD103+ T Cells Eliminate Damaged Alveolar Epithelial Type II Cells Under Oxidative Stress to Prevent Lung Tumorigenesis

open access: yesAdvanced Science, EarlyView.
This work unravels a novel function of CD103+ T cells in eradicating oxidative‐stressed somatic cells to prevent lung tumorigenesis and identifies specific CD103+ T cell‐decline as a key feature in the aged lung. This comprehensive study highlights the contribution of immuno‐dysregulation to the high incidence of aging‐associated lung cancers ...

Neuronal FGF13 Inhibits Mitochondria‐Derived Damage Signals to Prevent Neuroinflammation and Neurodegeneration in a Mouse Model of Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
This study elucidates a novel role of FGF13 in manipulating neuronal fate via mitochondrial transfer. FGF13 is identified as a mitochondria‐stabilizing protein by interacting with mitochondrial proteins. Under stress, the decrease of neuronal FGF13 fails to retain mitochondria within the cytoplasm, leading to the release of damaged mitochondria to ...

SNORA74A Drives Self‐Renewal of Liver Cancer Stem Cells and Hepatocarcinogenesis Through Activation of Notch3 Signaling

open access: yesAdvanced Science, EarlyView.
Abstract Liver cancer stem cells (CSCs) account for tumor initiation, heterogeneity and therapy resistance. However, the role of small nucleolar RNAs (snoRNAs) in the regulation of liver CSCs remains largely unclear. Here, this work identifies a conserved H/ACA box snoRNA SNORA74A which is highly expressed in liver CSCs.

Delayed Transplantation of Neural Stem Cells Improves Initial Graft Survival after Stroke

open access: yesAdvanced Science, EarlyView.
Delayed transplantation of human iPSC‐derived neural progenitor cells (NPCs) enhances graft survival, proliferation, and axonal sprouting after stroke. Using bioluminescence imaging and histology in a mouse model of stroke, it is shown that NPC delivery at 7 days post‐stroke is more effective than acute transplantation, highlighting the importance of ...

FIB‐3 index as a novel age‐independent predictor of liver fibrosis and prognosis in hepatocellular carcinoma patients undergoing hepatectomy

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
Fibrosis‐3 index (FIB‐3) can stratify the risk of the survival and the recurrence‐free survival. The FIB‐3 index is a reliable, age‐independent tool for assessing liver fibrosis and prognosis in HCC patients post‐hepatectomy. Its use may improve clinical outcomes and support personalized treatment strategies. Abstract Background Liver fibrosis is a key
