Gene expression changes in Neil1, Neil2 and Apex1 single knockout mouse embryonic stem cells prior and during embryoid body differentiation
The bifunctional DNA glycosylases/AP lyases NEIL1 and NEIL2 excise oxidative base damages, but can also enhance the steady-state turnover of thymine DNA glycosylase (TDG) during oxidative DNA demethylation (Schomacher et al. 2016; doi:10.1038/nsmb.3151) probably due to their AP lyase activity during base excision repair (BER). The dual role of NEILs in antagonizing base damages and promoting epigenetic gene reactivation prompted us to investigate the consequences of Neil-deficiency during embryonic stem cell differentiation. For comparison stem cells deficient for Apex1, the bona fide AP endonuclease during BER, were analysed in parallel. Overall design: RNA-seq gene expression profiling of wildtype, Neil1, Neil2 and Apex1 single knockout mouse embryonic stem cells (mESCs) and embryoid bodies (EBs) derived from them.
