Abstract:
Compounds causing DNA damage have been used widely in molecular biology and some are used as therapeutic agents in cancer therapy. In most cases, their cellular response is pleiotropic, making it challenging to develop these agents efficiently for potential therapeutic use. Furthermore, this means that such compounds can also affect healthy tissues, which is a major drawback for the use in therapy. Thus, dissecting and understanding not only their molecular mode of action, but also identifying all their cellular targets is critical. With the advent of high throughput DNA sequencing technologies our understanding of the genomic targets of such compounds has increased significantly over recent years. This review gives an overview of some well-studied DNA-damaging agents and dissects what is known about their molecular mode of action, their cellular response and use in clinical settings. It then describes how high throughput-sequencing approaches can be used (a) to study DNAdamaging compounds and (b) to gain insight into their biological activity in vivo.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
