Structural Polymorphism of polyG Inclusions Revealed by In Situ Cryo‐Electron Tomography

open access: yesAdvanced Science, EarlyView.
Correlative cryo‐electron tomography in primary cortical neurons and NIID mouse brain tissue reveals that polyG inclusions are interconnected ribbon‐like assemblies rather than canonical amyloid fibrils. Multiple compartment‐specific ribbon states show distinct 26S proteasome accessibility, while cytoplasmic ribbons contact and deform ER‐like ...

Reversing Temozolomide Resistance in Glioblastoma Based on Cuproptosis‐Mediated Positive Feedback Loop

open access: yesAdvanced Science, EarlyView.
To effectively reverse TMZ resistance, this work proposes a cuproptosis‐mediated positive feedback loop that integrates mitochondrial dysfunction, ATP depletion, AMPK‐p53 signaling, and glycolytic inhibition, ultimately amplifying cell death. This cuproptosis‐mediated feedback loop simultaneously disrupts multiple resistance pathways in GBM, including ...

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.

A Personalized Haplotype‐Resolved Near‐Gapless Genome Framework for Somatic Variant Discovery in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
A patient‐specific, haplotype‐resolved genome framework improves detection and interpretation of somatic variants in hepatocellular carcinoma. Using multi‐platform sequencing, the personalized assembly resolves complex regions including centromeres and MHC/HLA loci, enhances structural variant discovery, and links regulatory alterations to allele ...

Hypomethylation of GNA15 Promotes Pancreatic Ductal Adenocarcinoma Progression and Macrophage M2 Polarization via STAT3‐CXCL8 Axis

open access: yesAdvanced Science, EarlyView.
A schematic model summarizing GNA15's mechanism in mediating macrophage M2 polarization and Gemcitabine resistance. ABSTRACT The complexity of pancreatic ductal adenocarcinoma (PDAC) progression, coupled with the lack of effective immunotherapy, underscores the imperative to deepen our understanding of its mechanisms and identify suitable immune ...

Differential Tissue‐Coupled Powering for Battery‐Free Injectable Electroceuticals

open access: yesAdvanced Science, EarlyView.
A thread‐like injectable neural stimulator is powered through differential tissue‐coupled powering (DTCP), which harvests RF‐frequency tissue potentials with an elongated receiver while preserving a injectable cross‐section. The system integrates an ASIC, stimulation electrodes, and a portable transmitter, enabling wireless peripheral nerve stimulation,

EndoTac: An Endoscopic Camera‐Based Tactile Sensor with High Sensitivity for Minimally Invasive Surgery

open access: yesAdvanced Science, EarlyView.
EndoTac presents a trocar‐compatible endoscopic vision‐based tactile sensor that uses a convex mirror to enlarge side‐facing tactile coverage during minimally invasive vessel palpation. Distorted tactile images are unwarped and processed by a learning model to estimate vascular deformation, enabling sensitive, spatially distributed tactile perception ...
