DNA damage and repair refers to the creation and correction of DNA lesions that threaten genome integrity. Because DNA replication errors or environmental agents that damage DNA can introduce mutations if not corrected, multiple cellular DNA repair mechanisms exist to remove damaged regions of chromosome...
Over the last decade, the discovery of new targeted therapies against DNA damage signalling and repair has offered the possibility of therapeutic improvements in oncology. In this review, we summarize the current knowledge of DNA damage signalling and repair inhibitors, their molecular and cellular ...
2023年2月23日,华中农业大学严顺平教授团队在国际著名期刊EMBO Journal发表了题为“The SMC5/6 complex recruits the PAF1 complex to facilitate DNA double-strand break repair in Arabidopsis”的研究论文。该论文发现 SMC5/6复合体通过招募PAF1复合体介导DSB位点组蛋白H2B的单泛素化,从而促进HR修复。这不仅揭示...
DNA damage produces a variety of responses, including cell senescence, apoptosis and DNA repair. This review summarises the evidence for DNA damage in atherosclerosis, the cellular responses to damage and the mechanisms of signalling DNA damage. 关键词: Atherosclerosis Oxygen radicals DOI: 10.1016/...
