DNA damage response upon environmental contaminants: An exhausting work for genomic integrity

Following exposure to xenobiotics, cellular mechanisms will take place to prevent damages relative to i) DNA, to maintain genome integrity, ii) proteins, to maintain their activities, iii) lipids, to limit peroxidation. This system of cellular defence and resistance is energetically costly. In this commentary review, we discuss the impact of DNA damage and the DNA damage response (DDR) on energetic metabolism. Conversely, we address the question...
