RNA-seq and RRBS of developing zebrafish larval brain and WGBS of 4 week old WT and dnmt3aa/dnmt3ab CRISPR/CAS9 KO brain
Ontology highlight
ABSTRACT: DNA methylation predominantly occurs at CG dinucleotides in vertebrate genomes, however, non-CG methylation (mCH) is also detectable in vertebrate tissues, most notably in the nervous system. In mammalian brains, it is well established that: i) mCH is targeted to CAC trinucleotides by DNMT3A, ii) enriched in gene bodies and repetitive elements, and iii) associated with transcriptional repression. However, the possible conservation of these mCH features in zebrafish is largely unexplored and has yet to be functionally demonstrated. In this study, we analyse the transcriptomes (RNA-seq) and methylome (RRBS) of developing zebrafish larvae (1-6 weeks) and adult brain (6 month). We additionally elucidate a role for dnmt3aa/dnmt3ab in mCH deposition via CRISP/CAS9 KO and WGBS of 4 week old brains
