Targeting GPX4 to Induce Ferroptosis Overcomes Chemoresistance Mediated by the PAX8‐AS1/GPX4 Axis in Intrahepatic Cholangiocarcinoma

Advanced Science, EarlyView.
PAX8‐AS1 drives chemoresistance in intrahepatic cholangiocarcinoma by activating NRF2‐mediated GPX4 transcription and stabilizing GPX4 mRNA via IGF2BP3. Targeting the PAX8‐AS1/GPX4 axis with a GPX4 inhibitor enhances the efficacy of gemcitabine and cisplatin in preclinical models, offering a promising strategy to overcome chemotherapy resistance in ...

Effect of arsenic on benzo[a]pyrene DNA adduct levels in mouse skin and lung.

Carcinogenesis, 2003
Concomitant exposures to arsenic and polycyclic aromatic hydrocarbons (PAHs) such as benzo[a]pyrene (BaP) are widespread. While BaP acts by binding to and inducing mutations in critical sites on DNA, the mechanism(s) of arsenic carcinogenesis remains ...

CXCL6 Reshapes Lipid Metabolism and Induces Neutrophil Extracellular Trap Formation in Cholangiocarcinoma Progression and Immunotherapy Resistance

Advanced Science, EarlyView.
CXCL6's function in cholangiocarcinoma is underexplored. Here it is discovered that CXCL6 is upregulated in cholangiocarcinoma tissues and promotes proliferation and metastasis of it. CXCL6 functions through the CXCR1/2‐JAK‐STAT/PI3K axis and reshaping tumor lipid metabolism.

Photosensitizer Repositioning Affords an Enantiocomplementary Enzyme for [2 + 2]‐Cycloadditions

Angewandte Chemie, EarlyView.
In this study, we capitalize on the versatility offered by genetic code expansion to develop a proficient photoenzyme for [2 + 2]‐cycloadditions that is enantiocomplementary to our recently developed photoenzyme EnT1.3. By repositioning the genetically programmed benzophenone photosensitizer and subsequent directed evolution, we have developed an ...

CD103+ T Cells Eliminate Damaged Alveolar Epithelial Type II Cells Under Oxidative Stress to Prevent Lung Tumorigenesis

Advanced Science, EarlyView.
This work unravels a novel function of CD103+ T cells in eradicating oxidative‐stressed somatic cells to prevent lung tumorigenesis and identifies specific CD103+ T cell‐decline as a key feature in the aged lung. This comprehensive study highlights the contribution of immuno‐dysregulation to the high incidence of aging‐associated lung cancers ...

Small Molecule‐Induced Alterations of Protein Polyubiquitination Revealed by Mass‐Spectrometric Ubiquitome Analysis

Angewandte Chemie, EarlyView.
To monitor small molecule‐induced changes in protein polyubiquitination in an unbiased manner, we employ enrichment through tandem ubiquitin binding entities coupled to LC‐MS/MS analysis (TUBE‐MS). By applying the workflow to PROTAC, p97‐ and deubiquitinase‐inhibitor treatment of cells, we demonstrate its broad applicability and reveal the induction of
