Electrochemical Valence‐Regulated Biomimetic Nanozymes for Breast Cancer Metabolism Inhibition and Potentiated Catalytic Immunotherapy

Exploration, EarlyView.
MnOx nanozymes face low tumoricidal activity and PD‐L1‐mediated immune attenuation. Electrochemically regulated M‐MnOx with high oxidase activity was TCM‐wrapped into TMO. TMO targets tumors, triggers ICD, activates cGAS‐STING, antagonizes PD‐L1, and suppresses tumor recurrence, providing new insights for Mn‐based nanomaterials.

A Nitric Oxide–Based STING Agonist Nanoadjuvant With ICD‐Derived Membrane Antigens Unleashes Robust Antitumor Immunity

Exploration, EarlyView.
Schematic illustration of the synergistic antitumor mechanism of Im@NOnanoPL combined with αPD‐1 therapy. The Im@NOnanoPL nanovaccine targets lymph nodes via ICD‐derived tumor cell membranes, delivering personalized tumor antigens. It releases NO gas to enhance MHC‐I expression and activate the STING pathway, thereby potentiating anti‐tumor immunity in

Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Proteomic Analysis of Mixed Cell Membrane Extracts From Triple‐Negative Breast Cancer Cell Lines Revealed Broad Metabolic Reprogramming Associated With Tumor Progression

PROTEOMICS, EarlyView.
ABSTRACT Triple‐negative breast cancer (TNBC) represents the most aggressive subtype with limited therapeutic options and the poorest clinical outcomes. Using high‐resolution nUPLC‐QTOF‐MS/MS, we performed comprehensive proteomic profiling of TNBC cell lines representing disease progression stages: HCC‐1937 (stage IIB), HCC‐1599 (stage IIIA), and MDA ...

Regulating Lipid Metabolism in Cancer: The Therapeutic Potential of Traditional Chinese Medicine

Phytotherapy Research, EarlyView.
By regulating the reprogramming of lipid metabolism in tumor cells, TCM provides a novel strategy for antitumor therapy with reduced toxicity and enhanced efficacy. ABSTRACT Lipid metabolic reprogramming is a key feature of tumor cells to adapt to the microenvironment and plays an important role in tumor growth, invasion, and metastasis.

HER2‐Targeted AIE Nanotheranostics Overcome SHR‐A1811 Resistance via Immunogenic Pyroptosis and Tumor‐Associated Macrophage Reprogramming in Breast Cancer

Small, EarlyView.
HER2‐targeted AIE780‐A1811 nanoparticles self‐assemble via amide coupling of a mitochondria‐directed photosensitizer with the ADC SHR‐A1811. Upon 660 nm irradiation, they generate ROS, photothermal effects, and controlled drug release, inducing immunogenic pyroptosis and M2‐to‐M1 macrophage reprogramming. This dual action remodels the immunosuppressive
