Genome-wide bisulfite sequencing (GWBS) and RNA-seq in hippocampus of Neil1- and Neil2 deficient mice

We report the bisulfite sequencing and RNA-seq in hippocampus of Neil deficient adult mice. By genome-wide bisulphite sequencing (GWBS) analysis, NEIL depletion mice (including Neil1-/-, Neil2-/- and Neil1-/- Neil2-/-) consistently displayed global hypo-methylation of 5mC in base resolution in CG context, as well as in gene feature regions including transcription start sites (TSS) in CHG and CHH context by compared to wild type. RNA-seq reveals differentially expressed genes are mainly overlapped with differential methylation. A subset of overlap genes is enriched in synaptic function. Together, NEIL1 and NEIL2 functionally promote DNA methylation and impact gene expression.
