Extended self-renewal and accelerated reprogramming in the absence of Kdm5b [ChIP-Seq]

ABSTRACT: ES cell pluripotency is thought to be regulated in part by H3K4 methylation. However, it is unclear how H3K4 demethylation contributes to ES cell function and participates in iPS cell reprogramming. Here, we show that KDM5B, which demethylates H3K4, is important for ES cell differentiation, and presents a barrier to the reprogramming process. Depletion of Kdm5b leads to an extension in the self-renewal of ES cells in the absence of LIF. Transcriptome analysis revealed the persistent expression of pluripotency-genes and underexpression of developmental genes during differentiation in the absence of Kdm5b, suggesting that KDM5B plays a key role in cellular fate changes. We also observed accelerated reprogramming of differentiated cells in the absence of Kdm5b, demonstrating that KDM5B is a b
