DNA-Protein Cross-Links Derived from Abasic DNA Lesions: Recent Progress and Future Directions.
Covalent DNA-protein cross-links (DPCs), if not resolved, can block DNA replication and transcription, resulting in genome instability. Compared to other types of DNA damage, how DPCs are formed and repaired is less understood. This review focuses on recent findings concerning DPCs derived from two types of abasic DNA lesions, apurinic/apyrimidinic sites and 3'-phospho-α,β-unsaturated aldehydes. It summarizes the newly reported DPCs and their identification by liquid chromatography tandem mass spectrometry. It also reviews the approaches for synthesizing stable and site-specific DPCs, and their applications for discovering the corresponding repair mechanisms. Finally, it discusses the future directions to better understand the mechanistic formation and repair of those DPCs.
期刊介绍：
Chemical Research in Toxicology publishes Articles, Rapid Reports, Chemical Profiles, Reviews, Perspectives, Letters to the Editor, and ToxWatch on a wide range of topics in Toxicology that inform a chemical and molecular understanding and capacity to predict biological outcomes on the basis of structures and processes. The overarching goal of activities reported in the Journal are to provide knowledge and innovative approaches needed to promote intelligent solutions for human safety and ecosystem preservation. The journal emphasizes insight concerning mechanisms of toxicity over phenomenological observations. It upholds rigorous chemical, physical and mathematical standards for characterization and application of modern techniques.
