Multicohort Validation of Gut Microbiome Signatures for Cholangiocarcinoma Diagnosis and Functional Characterization of Bifidobacterium Pseudocatenulatum

open access: yesAdvanced Science, EarlyView.
This study analyzes gut bacteria in cholangiocarcinoma patients, revealing distinct microbial signatures that enable accurate disease detection. Species‐based diagnostic models achieved over 98% accuracy in identifying cholangiocarcinoma and distinguished it from other liver diseases. The research demonstrates that specific beneficial bacteria suppress

Intracellular Aβ42 Sequestration by a Serine Protease Mitigates Neurotoxicity in a Drosophila Alzheimer's Disease Model

open access: yesAdvanced Science, EarlyView.
Emerging evidence suggests that intraneuronal Aβ accumulation represents an early pathogenic event in Alzheimer's disease (AD). Using Drosophila AD model, this study shows that a nonsecreted serine protease Yip7 physically interacts with Aβ. This causes intraneuronal Aβ accumulation but surprisingly reduces the associated neurotoxicity, arguing that ...

Delivery of Pleckstrin‐Homology Domains Suppresses PI3K/Akt Signaling and Breast Cancer Metastasis

open access: yesAdvanced Science, EarlyView.
Current therapies curb tumor growth but not metastasis. Obscurin, a giant metastasis suppressor lost in breast cancer, restrains PI3K/Akt signaling but is impractical to restore. We deploy a mini‐obscurin, comprising the obscurin‐PH‐domain, which sequesters PI3K‐p85, potently suppressing invasion and metastasis.

A Dual‐Responsive Versatile Nanohybrid Orchestrating Tumor Elimination and Tumor‐Associated Osteolysis Restoration via Sequential Release

open access: yesAdvanced Science, EarlyView.
The versatile CaO2@CuMOF@HAP nanohybrid demonstrates an outstanding MMP9/pH‐triggered release performance for sequential release of osteogenic growth peptide into deep‐seated tumor‐infiltrated bone destruction areas and dual ions into tumor cells, enabling efficient tumor‐associated osteolysis restoration and tumor elimination for more comprehensive ...

Targeted Mitochondrial ECSIT Overexpression Attenuates MASH by Increasing OTUD3 Expression

open access: yesAdvanced Science, EarlyView.
Mitochondrial ECSIT expression is reduced during MASH pathogenesis. Overexpression of mitochondrial ECSIT mitigates steatohepatitis and maintains hepatic metabolic homeostasis. Mechanistically, ECSIT enhances intramitochondrial OTUD3 expression to stabilize SIRT3 through deubiquitination, thus preserving mitochondrial function and impeding disease ...

NK Cell Activation by Platinum Boosts Immunotherapy in HR+/HER2− Breast Cancer

open access: yesAdvanced Science, EarlyView.
Multi‐omics and single‐cell analyses identify activated NK cells as key mediators of anti‐PD‐(L)1 response in HR+/HER2− breast cancer. Platinum chemotherapy enhances NK cell cytotoxicity through NF‐κB–associated signaling, synergizing with immunotherapy and providing a rationale for combination treatment.

Tetrastigma Hemsleyanum Polysaccharide Suppresses Triple‐Negative Breast Cancer by Disrupting the Hippo‐YAP/TEAD4‐PDIA4 Axis and Endoplasmic Reticulum Stress Adaptation

open access: yesAdvanced Science, EarlyView.
ABSTRACT Triple‐negative breast cancer (TNBC) exhibits addiction to chronic endoplasmic reticulum (ER) stress, which sustains an aggressive metastatic phenotype through activation of the unfolded protein response (UPR). Here, we identify a previously unrecognized “ER‐stress addiction” axis in which the Hippo pathway effector TEAD4 directly ...

Reduced Maintenance DNA Methylation Thresholds Enable Sensitive Reporter Assays for UHRF1 and DNMT1 Inhibition

open access: yesAdvanced Science, EarlyView.
The authors engineer colorectal cancer cells with reduced redundancy of UHRF1 and DNMT1, key DNA methylation maintenance factors, lowering the maintenance threshold and sensitizing cells to inhibition. They develop reporter assays driven by endogenous tumor‐suppressor gene promoters with enhanced sensitivity and dynamic range to demethylating drugs ...

Elevated TRIM25 Impairs Poly (ADP‐ribose) Metabolism via PARG Degradation and Mediates Compression‐Induced Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
TRIM25 acts as a multifunctional hub driving intervertebral disc degeneration under mechanical stress. Mechanical compression significantly upregulates TRIM25 expression, establishing it as a key E3 ubiquitin ligase platform. TRIM25 targets PARG and Ku80 via distinct molecular interfaces, triggering their ubiquitination and degradation.
