Our understanding of the DNA repair mechanisms that preserve genome integrity has increased greatly in recent years. To follow the DNA repair process, researchers have developed sophisticated techniques including live cell imaging, local damage induction and refined biochemical assays. These techniques have helped to elucidate the 'orchestration' of DNA repair mechanisms (i.e. the order of factor assembly around the lesion, the identification of new functions of known factors and the discovery of novel key regulators involved in DNA repair). We will discuss the uses and the limitations of these methods and their applications in the study of DNA repair.
近年来,我们对维持基因组完整性的DNA修复机制的理解有了极大的提高。为了追踪DNA修复过程,研究人员开发了复杂的技术,包括活细胞成像、局部损伤诱导和精细的生化分析。这些技术有助于阐明DNA修复机制的“编排”(即损伤周围因子组装的顺序、已知因子新功能的鉴定以及参与DNA修复的新型关键调节因子的发现)。我们将讨论这些方法的用途和局限性及其在DNA修复研究中的应用。
