Targeted Delivery of α‐ketoglutarate to Macrophages in Bone: A Novel Therapeutic Strategy for Improving Fracture Healing in Type 2 Diabetes

open access: yesAdvanced Science, EarlyView.
The study reveals that glutaminolysis in macrophages is inhibited under type 2 diabetes mellitus (T2DM) conditions, which impedes fracture healing by reducing bone morphogenetic protein 2 (BMP2) production through increased cytosine methylation on the promoter.

PLXDC1+ Tumor‐Associated Pancreatic Stellate Cells Promote Desmoplastic and Immunosuppressive Niche in Pancreatic Ductal Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
This study uncovers the activation, heterogeneity, and regulatory roles of pancreatic stellate cells (PSCs) at single‐cell and spatial levels. It further identifies PLXDC1+ PSCs near aggressive LRRC15+ cancer‐associated myofibroblasts and SPP1+ macrophages, forming a desmoplastic and immunosuppressive tumor niche that promotes CD8+ T cell exhaustion ...

Nanoneedle‐Based Electroporation for Efficient Manufacturing of Human Primary Chimeric Antigen Receptor Regulatory T‐Cells

open access: yesAdvanced Science, EarlyView.
Low reproducibility and inefficient gene transfer hamper clinical manufacturing of chimeric antigen receptor regulatory T cells (CAR Tregs). Nanoneedle mediated electroporation generates primary human CAR Tregs under good manufacturing practice conditions with superior efficiency compared to viral transduction.

Glycolysis‐Derived Lactate Induces ACSL4 Expression and Lactylation to Activate Ferroptosis during Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
Glycolysis‐derived lactate activates nucleus pulposus cell ferroptosis via Histon H3K18la‐mediated ACSL4 transcription and ACSL4 lactylation and aggravate intervertebral disc degeneration. Inhibiting glycolysis via gene silencing or chemical intervention reduces the production of lactate and ameliorates ferroptosis activation and nucleus pulposus ...

M2 Macrophage‐Derived Extracellular Vesicles Reprogram Immature Neutrophils into Anxa1hi Neutrophils to Enhance Inflamed Bone Regeneration

open access: yesAdvanced Science, EarlyView.
This study reveals that M2‐EVs mitigate periodontitis‐induced bone resorption by modulating neutrophil fate. Single‐cell RNA sequencing identified an Anxa1hi neutrophil subpopulation with pro‐reparative properties. M2‐EVs disrupt neutrophil maturation, promoting this subpopulation through key reprogramming genes (Acvrl1, Fpr2). These findings highlight

ISG15 Enhances the Activity of γ‐Glutamate Cysteine Ligase to Suppress Apoptosis in High Fat Diet‐Promoted Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
Hepatocellular carcinoma (HCC) cells under high‐fat environment constrain harmful reactive oxygen species (ROS) by enhancing glutathione synthesis though upregulating interferon stimulated gene 15 (ISG15). In this process, upregulated high mobility group A1 (HMGA1) enhances ISG15 transcription, upregulated ISG15 subsequently noncovalently binds with ...

Halofuginone Disrupted Collagen Deposition via mTOR‐eIF2α‐ATF4 Axis to Enhance Chemosensitivity in Ovarian Cancer

open access: yesAdvanced Science, EarlyView.
COL1A1, a major component of ECM, contributes to chemoresistance and poor prognosis in ovarian cancer. Halofuginone (HF) attenuates CAF‐secreted COL1A1 through mTOR‐eIF2α‐ATF4 axis. Notably, HF disrupts collagen deposition to form the looser ECM and facilitates CD8+ T cell infiltration, partially via M2‐M1 macrophage polarization to enhance ...

ALKBH3‐Mediated M1A Demethylation of METTL3 Endows Pathological Fibrosis:Interplay Between M1A and M6A RNA Methylation

open access: yesAdvanced Science, EarlyView.
RNA modification is crucial in fibrosis diseases, but the role of m1A modification remains elusive. This study reveals that ALKBH3, an m1A demethylase, drives skin fibrosis by reshaping m6A RNA modification and stabilizing COL1A1 and FN1 mRNAs through METTL3, uncovering a crosstalk between m1A and m6A methylation in pathological events.

METTL14‐Induced M6A Methylation Increases G6pc Biosynthesis, Hepatic Glucose Production and Metabolic Disorders in Obesity

open access: yesAdvanced Science, EarlyView.
It is shown that obesity is associated with increases in hepatic METTL14 and m6A methylation of G6pc transcript. YTHDF1 and YTHDF3 bind to m6A‐marked G6pc mRNA to increase its synthesis. Hepatocyte‐specific deletion of Mettl14 decreases G6pc m6A methylation, G6pc biosynthesis, and G6pc‐mediated gluconeogenesis, alleviating glucose metabolic defects in ...
