Signalling cell cycle arrest and cell death through the MMR System [PDF]

, 2006
Loss of DNA mismatch repair (MMR) in mammalian cells, as well as having a causative role in cancer, has been linked to resistance to certain DNA damaging agents including clinically important cytotoxic chemotherapeutics.

Amplifying Anti‐Tumor Immune Responses via Mitochondria‐Targeting Near‐Infrared Photodynamic Therapy

Advanced Science, EarlyView.
Interfacial Nd3+‐triplet energy transfer enables direct activation of molecular triplets under near‐infrared (NIR) irradiation for reactive oxygen species (ROS) generation. Photodynamic therapy (PDT) exaggerates hypoxia, which initiates subsequent hypoxia‐activated chemotherapy.

Self‐Assembly of a Customizable Library of Nickel Trifluoromethylation Catalysts via Selective C─F and C─O Bond Cleavage

Angewandte Chemie, EarlyView.
Carbatranes and anionic pincer ligands were self‐assembled via one‐pot C─F or C─O bond cleavage and the formation of C─O, C─N, or C─C bonds, forming ligand architectures inaccessible by common synthetic methods. This approach allowed to build a customizable library of nickel catalysts for light‐induced C─H bond trifluoromethylation.

DNA Adductomics: A Narrative Review of Its Development, Applications, and Future

Biomolecules
DNA adductomics is the global study of all DNA adducts and was first proposed in 2006 by the Matsuda group. Its development has been greatly credited to the advances in mass spectrometric techniques, particularly tandem and multiple-stage mass ...

Unexpected transformation of dissolved phenols to toxic dicarbonyls by hydroxyl radicals and UV light. [PDF]

, 2018
Water treatment systems frequently use strong oxidants or UV light to degrade chemicals that pose human health risks. Unfortunately, these treatments can result in the unintended transformation of organic contaminants into toxic products.

Pyroptosis‐Inducing Platinum(IV) Prodrugs via GSDME Pathway for Chemoimmunotherapy and Metastasis Inhibition in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
Three PtIV prodrugs MRP, DRP, and HRP are designed to induce pyroptosis in low GSDME‐expressing tumor cells via the Caspase‐3/GSDME pathway. By relaxing chromatin and reactivating GSDME, HRP can effectively induce pyroptosis, enhance pro‐inflammatory cytokine production, and exhibit potent antitumor effects.

Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

Hepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

A Genetically Encoded Homocysteine Precursor to Probe Protein Active Sites and to Addict Escherichia coli to a Noncanonical Amino Acid Directly Involved in Catalysis

Angewandte Chemie, EarlyView.
A new genetically encoded amino acid is chemically converted into homocysteine (Hcy) under mild conditions to probe and to activate protein active sites. Surprisingly, Hcy can replace cysteine or serine residues in several enzymes. Its potential for a widespread use in proteins is further underlined by rendering Escherichia coli dependent on Hcy ...

Adaptive Response Enzyme AlkB Preferentially Repairs 1-Methylguanine and 3-Methylthymine Adducts in Double-Stranded DNA [PDF]

, 2018
The AlkB protein is a repair enzyme that uses an α-ketoglutarate/Fe(II)-dependent mechanism to repair alkyl DNA adducts. AlkB has been reported to repair highly susceptible substrates, such as 1-methyladenine and 3-methylcytosine, more efficiently in ss ...
