NPM1 Mediates mRNA Sorting into Extracellular Vesicles via Specific RNA Motif Binding and Phase Separation

open access: yesAdvanced Science, EarlyView.
NPM1 selectively sorts specific mRNAs into extracellular vesicles (EVs) by recognizing RNA motifs and forming phase‐separated condensates. These mRNA cargos—including EGFR—are then loaded via multivesicular bodies. This active sorting pathway, validated in EVs derived from both lung cancer cells and patient serum, reveals a specific mechanism for ...

Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy

open access: yesAdvanced Science, EarlyView.
Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.

Understanding and Overcoming Antibody‐Drug Conjugate Resistance: Biological Mechanisms and Emerging Analytical Frameworks in Breast Cancer

open access: yesAdvanced Science, EarlyView.
Antibody–drug conjugates (ADCs) transform breast cancer therapy, yet resistance limits their durability. Emerging evidence reveals that ADC failure is not solely tumor‐intrinsic but shaped by dynamic tumor–microenvironment interactions that alter drug delivery, processing, and response.

The role of MRI and clinicopathologic features in predicting the invasive component of biopsy-confirmed ductal carcinoma in situ

open access: yesBMC Medical Imaging, 2020
Background The upgrade rate of biopsy-confirmed ductal carcinoma in situ (DCIS) to invasive carcinoma is up to 50% on final pathology. We investigated MRI and clinicopathologic predictors of the invasive components of DCIS diagnosed by preoperative ...

Hepatocyte PIEZO1 Negatively Regulates Lipogenesis and Ameliorates MASLD by Sensing Membrane Tension and Activating AMPK

open access: yesAdvanced Science, EarlyView.
Hepatocytes are subjected to increased membrane tension along with lipid accumulation. Loss of PIEZO1 exacerbates high‐fat diet‐induced MASLD in mice. Activation of PIEZO1 alleviates high‐fat diet‐induced MASLD in mice. PIEZO1 negatively regulates de novo lipogenesis through activation of CaMKK2‐AMPK pathway. ABSTRACT Liver is a central organ for lipid

β‐Adrenergic Signaling Promotes Anti‐Tumor Immunity in TP53‐mutant Oral Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
β‐adrenergic stimulation enhances anti‐tumor immunity in TP53‐deficient oral squamous cell carcinoma by inducing tumor‐derived secretion of CXCL10, which attracts and activates cytotoxic CD8+ T cells. The findings demonstrate that β‐adrenergic signaling alters tumor–immune interactions via CXCL10‐mediated paracrine activation, revealing a neuro‐immune ...

Highly Active Cu14 Cluster Precisely Activates Autophagy Inhibitor to Amplify Cuproptosis Immunotherapy

open access: yesAdvanced Science, EarlyView.
An atomically precise Cu14 cluster‐mediated bond scission reaction pioneers the amplification of the antitumor immune response via synergetic cuproptosis‐associated immunogenic cell death induction and in situ autophagy blockade. ABSTRACT Transition metal‐mediated cleavage mechanisms have emerged as an effective means to mitigate the off‐target ...
