E-MTAB-10264 - Microarray analysis of Caenorhabditis elegans exposed to three hydrophilic genotoxicants in water in duplicate
Released on 23 April 2021, last updated on 2 December 2021
In this study, we exposed Caenorhabditis elegans wild types N2 to two concentrations of the model genotoxicants formaldehyde (HCHO), N-ethyl-N-nitrosourea (ENU), and methyl methanesulfonate (MMS).We performed a concentration-response test to determine the non-toxic concentration range for studying the transcriptional effects of compounds. In microarray experiments, we studied two concentrations (1 mM and 5 mM) for each compound and a control of M9 medium. Age synchronized worms at developmental L4 larval stage were exposed to treatment for two hours. After flash freezing the samples, RNA was isolated, labeled and hybridized on oligo microarray (Agilent) slides.
