Epigenomic (RRBS) analyses in brains of exposed F0 zebrafish and their unexposed F1 and F2 offspring after early-life exposure to permethrin 10 microg/L


ABSTRACT: In the present study, zebrafish were exposed to permethrin during early-life, and F1 and F2 generations were bred unexposed. Permethrin exposed F0 fish showed a hypoactive phenotype at adulthood, whereas males from the F1 and F2 generations showed a decrease in anxiety-like behavior. We performed transcriptomic analyses on whole brains (GSE154020), and here, we further performed RRBS analyses to identify whether there was any stable change in DNA methylation that could be linked to the effects observed at other levels of organization. Due to technical issues during sequencing, we had to perform a correction on the raw data (CombaT) in order to remove a batch effect (flow-cell). We made sure that this did not create any false-positive differentially methylated region. Processed files available are the results from methyl calling before batch correction(with a min coverage >= 5 per C). A matrix of corrected data is available as supplementary file.
