Cooperative role of LSD1 and CHD7 in regulating differentiation of mouse embryonic stem cells.

ABSTRACT: Lysine-specific histone demethylase 1 (LSD1) is a histone demethylase that plays a critical role in epigenetic regulation by removing the methyl group from mono- and di-methylated lysine 4 on histone H3 (H3K4me1/2), acting as a repressor of gene expression. Recently, catalytically independent functions of LSD1, serving as a scaffold for assembling chromatin-regulator and transcription factor complexes, have been identified. Herein, we show for the first time that LSD1 interacts with chromodomain-helicase-DNA-binding protein 7 (CHD7) in mouse embryonic stem cells (ESCs). To further investigate the CHD7-LSD1 crosstalk, we engineered Chd7 and Chd7/Lsd1 knockout (KO) mouse ESCs. We show that CHD7 is dispensable for ESC self-renewal and survival, while Chd7 KO ESCs can differentiate towards emb
