ChIP-sequencing of the H3K4me1 in crypts from mice intestinal epithelium with intestinal epithelium specific LSD1 knock out compared to wild type
To study the epigenetic regulation of intestinal epithelium we focus on the role of chromatin modulators. Lysine-specific histone demethylase 1a (KDM1A, LSD1) is one of the enzymes that can erase the H3K4me1/2 mark. To assess the role of LSD1 in intestinal epithelium we studied wild type (WT) (Villin-Cre -; Lsd1f/f) and intestinal-epithelial-specific knock-out (KO) (Villin-Cre+; Lsd1f/f) mice. We found that KO mice completely lack Paneth cells, and have altered stem cell characteristics compared to WT littermates. To assess genome-wide H3K4me1 levels in WT and KO small intestines, we sorted small intestinal crypt cells, fixed them, isolated chromatin, and performed ChIP using an H3K4me1 antibody as described in the protocols.
