Xanthatin Targets CISD1 to Drive Ferroptosis and Mitophagy as a Dual Anticancer Strategy in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
Triple‐negative breast cancer has a poor prognosis. Xanthatin directly targets and degrades CISD1, triggering ferroptosis through iron dysregulation. The concurrently activated mitophagy synergistically amplifies ferroptotic cell death. Xanthatin also demonstrates potent in vivo anti‐tumor efficacy with minimal toxicity, highlighting its therapeutic ...

Coacervate‐Mediated Lysosome‐Targeting Antibody Delivery for Protein Degradation

Advanced Science, EarlyView.
Targeting coacervates to the lysosome in the cytoplasm is a challenge. Here, we convert a tetrapeptide into lysosome‐targeting, membrane‐translocating coacervates. The lysosome‐sorting peptide coacervates facilitate coacervate‐mediated delivery of antibody antigen complexes and a PROTAC compound to the lysosome for the targeted degradation of cancer ...

Integrating Spatial Proteogenomics in Cancer Research

Advanced Science, EarlyView.
Xx xx. ABSTRACT Background: Spatial proteogenomics marks a paradigm shift in oncology by integrating molecular analysis with spatial information from both spatial proteomics and other data modalities (e.g., spatial transcriptomics), thereby unveiling tumor heterogeneity and dynamic changes in the microenvironment.

Targeted Degradation of eEF2K by a Structure‐Guided PROTAC Strategy for the Treatment of Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study developed an eEF2K‐targeting PROTAC, A6, that efficiently degrades eEF2K in TNBC cells, inhibiting tumor growth in vitro and in vivo. To enhance tumor‐specific delivery, we engineered A6@ZIF‐8, a pH‐sensitive nanocarrier, which improved drug accumulation at tumor sites, offering a promising therapeutic strategy for TNBC through targeted ...

Dual Aptamers‐Based SETDB1 PROTACs as Effective Anti‐Tumor Strategies for Breast Cancer

Advanced Science, EarlyView.
This study establishes dual‐aptamer PROTACs targeting SETDB1 using a SETDB1‐specific aptamer conjugated to AS1411. The designed PROTACs penetrate cells, recruit MDM2 to degrade SETDB1, and inhibit cancer cell proliferation and migration. Remarkably, they also overcome tamoxifen resistance and enhance CD8+ T cell cytotoxicity, suppressing tumor growth ...
