Methodological considerations for mutagen exposure in C. elegans

Methods. 2014 Aug 1;68(3):441-9. doi: 10.1016/j.ymeth.2014.04.011. Epub 2014 Apr 21.


Maintenance of the genome requires the continual repair of DNA lesions. Exposure of nematodes to DNA damage-inducing agents is a powerful method to rapidly ascribe a role for specific genes in DNA repair and to define epistatic relationships to other repair genes which allows for the construction of repair pathways. Despite the extensive use of these agents, however, differences in dosing, timing, and handling makes it difficult to compare results across laboratories. We provide herein a consideration of the parameters that influence the results of these exposures and detailed protocols for the exposure to mutagenic inducing agents.

Keywords: DNA damage repair; Double-strand breaks; Mutagen.
