PRMT5‐Dependent Stabilization of VPS34 Orchestrates Copper Trafficking to Shield Cancer Cells from Cuproptosis and Radiotherapy

open access: yesAdvanced Science, EarlyView.
Radioresistance arises partly from tumor cells evading cuproptosis via unknown defenses. This study reveals that the PRMT5‐VPS34 axis acts as a radiation‐activated anticuproptotic mechanism: PRMT5 methylates VPS34 at Arg174, recruiting USP10 to remove K48‐linked ubiquitination and prevent degradation.

ER-Targeted Beclin 1 Supports Autophagosome Biogenesis in the Absence of ULK1 and ULK2 Kinases

open access: yesCells, 2019
Autophagy transports cytoplasmic material and organelles to lysosomes for degradation and recycling. Beclin 1 forms a complex with several other autophagy proteins and functions in the initiation phase of autophagy, but the exact role of Beclin 1 ...

Introducing Borsantrazole: A Trifunctional Boron‐Based Pyrazole That Extends the Lifespan of Amyotrophic Lateral Sclerosis Mice

open access: yesAdvanced Science, EarlyView.
Herein we report a boron‐based pyrazole, (Borsantrazole ‐ a small molecule that selectively targets oxidative stress) that significantly increases survival, reduces weight loss, delays disease onset, and affects global protein changes in the SOD1‐G37R mouse model of ALS.

Inhalable ROS‐Responsive Nanospray Activates PPAR‐γ to Restore Macrophage Mitochondrial Homeostasis and Attenuate Radiation‐Induced Lung Injury

open access: yesAdvanced Science, EarlyView.
A nebulized nanoassembly alleviates radiation‐induced lung injury by reprogramming macrophages through coordinated ROS scavenging, NAD+ replenishment, and PPAR‐γ activation. Redox balance, mitochondrial homeostasis, and immune regulation are restored, revealing a microenvironment‐centered strategy for localized radioprotection.

8‐Oxoguanine Modified CircMTUS1 Drives PABPC1 Phase Separation to Promote Gastric Cancer Progression and Cisplatin Resistance via Autophagy

open access: yesAdvanced Science, EarlyView.
ABSTRACT Gastric cancer (GC) is a major global health concern, as its prevention and treatment remain significant challenges. The 8‐oxoguanine (o8G) modification of circRNAs, alongside their capacity to orchestrate liquid‐liquid phase separation (LLPS) and autophagy, plays a pivotal role in driving tumor progression and determining therapeutic outcomes.

Systemic Nanomechanical Single‐Cell Profiling Reveals Mechanophenotype Transitions Under Therapeutic Perturbation

open access: yesAdvanced Science, EarlyView.
Single‐cell mechanomics demonstrates that pharmacological perturbation changes cytoskeletal and cortical structure, suppressing cancer cell invasiveness. By integrating atomic force microscopy (AFM)‐based cortical measurements with stimulated emission depletion (STED)‐resolved adhesion and cytoskeletal organization, this approach identifies nanoscale ...

A Glucose Metabolism‐Modulatory Nanobiohybrid Vaccine Platform Promotes Anti‐Tumor Immunity by Orchestrating Autophagy‐Dependent Cross‐Presentation and H2S‐Enhanced NLRP3 Inflammasome Signaling

open access: yesAdvanced Science, EarlyView.
A nanobiohybrid vaccine was designed by constructing a hydrogen‐bonded organic framework coencapsulated with glucose oxidase (GOx) and tumor antigens. This nanobiohybrid vaccine executed a GOx‐catalyzed enzyme reaction that disrupted glucose metabolism and induced redox imbalance in dendritic cells, leading to autophagy‐dependent antigen cross ...

Gut Microbial Release of Ferulic Acid From Germinated Quinoa Alleviates Obesity‐Associated Cognitive Impairment by Activating Hippocampal Mitophagy Associated with PINK1/Parkin Pathway

open access: yesAdvanced Science, EarlyView.
Liberation of ferulic acid by gut microbial feruloyl esterase mediates cognitive enhancement of germinated quinoa (GQF) on obese mice. Ferulic acid enriched in GQF is released by gut microbes Roseburia hominis and R. intestinalis and subsequently mediates the neuroprotective effects of GQF on obesity‐induced cognitive decline by activating hippocampal ...

Atg14: A Key Player in Orchestrating Autophagy

open access: yesInternational Journal of Cell Biology, 2011
Phosphorylation of phosphatidylinositol (PtdIns) by a PtdIns 3-kinase is an essential process in autophagy. Atg14, a specific subunit of one of the PtdIns 3-kinase complexes, targets the complex to the probable site of autophagosome formation, thereby ...

O‐GlcNAcylation Regulation of SNAP29‐Dependent Autophagy Activation Dictates Chemoresistance in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
Model illustrating the proposed mechanism by which chemotherapy‐induced downregulation of OGT disrupts SNAP29 O‐GlcNAcylation, promoting STX17‐SNAP29‐VAMP8 SNARE complex assembly and protective autophagy, leading to chemoresistance, which in turn establishes a feedforward loop to perpetuate drug tolerance.
