Rapid Arbitrary‐Shape Microscopy of Unsectioned Tissues for Precise Intraoperative Tumor Margin Assessment

open access: yesAdvanced Science, EarlyView.
This study presents a novel microscopic imaging system capable of rapid, section‐free scanning of irregular tissue surfaces, delivering high sensitivity for detecting cancer cell clusters during intraoperative tumor margin assessment. Abstract Rapid and accurate intraoperative examination of tumor margins is crucial for precise surgical treatment, yet ...

Ferroptosis‐Mediated Hippocampal Neuronal Loss Post‐mTBI: Chromatin Accessibility Profiling and Single‐Nucleus Transcriptomics

open access: yesAdvanced Science, EarlyView.
Hippocampal single ‐nucleus transcriptomes and chromatin accessibility after mild traumatic brain injury reveal dentate granule neuron vulnerability driven by ferroptosis. The c‐Jun–Tmsb4x–Slc2a2 axis modulates lipid peroxidation and iron dysregulation.

Unpaired Learning‐Enabled Nanotube Identification from AFM Images

open access: yesAdvanced Science, EarlyView.
Identifying nanotubes on rough substrates is notoriously challenging for conventional image analysis. This work presents an unpaired deep learning approach that automatically extracts nanotube networks from atomic force microscopy images, even on complex polymeric surfaces used in roll‐to‐roll printing.

Spatial Profiling Reveals Distinct Molecular and Immune Evolution of Mouse Lung Adenocarcinoma Precancers with or Without Carcinogen Exposure

open access: yesAdvanced Science, EarlyView.
Tumor evolution in lung adenocarcinoma is shaped by genetic alterations and spatial immune dynamics. By integrating whole‐exome sequencing, imaging mass cytometry, and spatial transcriptomics across two mouse models, this study reveals how mutational burden, immune infiltration, and cell–state interactions evolve during early and late carcinogenesis ...

Bacteriophage‐Mimetic DNA Origami Needle for Targeted Membrane Penetration and Cytosolic Cargo Delivery

open access: yesAdvanced Science, EarlyView.
We designed a synthetic DNA origami needle‐like structure inspired by bacteriophages for targeted drug delivery. Functionalized with trastuzumab antibodies, cholesterol, and dyes, it selectively targets SKBR3 cancer cells. A glutathione‐triggered dye payload enables controlled release, and delivery is verified using confocal microscopy and live cell ...

Contribution of Gli1+ Adventitial Stem Cells to Smooth Muscle Cells in Atherosclerosis and Vascular Injury

open access: yesAdvanced Science, EarlyView.
Gli1+ adventitial stem cells (ASCs) have been thought to generate smooth muscle cells (SMCs) in atherosclerosis. Using a dual‐recombinase lineage tracing to exclude ectopic labeling, Wang et al. found that Gli1+ ASCs do not contribute to SMCs in atherosclerotic plaques.

The Gut Microbiota Regulates Motor Deficits via Butyrate in a Gnal+/− Mouse Model of DYT25 Dystonia

open access: yesAdvanced Science, EarlyView.
The present study provides compelling evidence for a modulatory role of the gut microbiota in the pathology of DYT25 dystonia, and butyrate supplementation alleviates the motor deficits of dystonia in Gnal+/− mice. Abstract Dystonia is the third most common movement disorder, following essential tremor and Parkinson's disease. The underlying mechanisms

Dual Targeting of Tau Kinases and Autophagy by Abemaciclib Independent of CDK4/6 Inhibition

open access: yesAdvanced Science, EarlyView.
Abemaciclib rescues cognitive function and attenuates tau pathology in Alzheimer's disease models, but not through its known cancer‐fighting mechanism. This study demonstrates that abemaciclib operates independently of CDK4/6 inhibition, instead directly targeting tau kinases CaMKII and GSK3β while simultaneously promoting autophagic clearance of ...

Flipping the Switch: MeCP2‐Mediated Lactylation Rewires Microglial Metabolism and Inflammation via the HK2/mTOR Axis in Poststroke Neuroinflammation

open access: yesAdvanced Science, EarlyView.
Stroke‐induced lactate accumulation promotes p300‐mediated lactylation of methyl‐CpG binding protein 2 (MeCP2) at lysine 210, which reprograms microglial metabolism toward glycolysis and activates the hexokinase 2 (HK2)/mTOR axis. This cascade promotes proinflammatory responses and impairs neurofunctional outcomes.
