H3K4me1 ChIP-seq of mouse small intestinal epithelium at different development stages (E18.5, P7, P21)


ABSTRACT: To assess the role of H3K4me1 in development in mouse small intestinal epithelium, we isolated intestinal epithelium tissue from wild type mice at E18.5, P7 and P21. This tissue was digested to single cells, sorted, fixed, isolated chromatin, and performed ChIP using an H3K4me1 antibody as described in the protocols.

Intestinal epithelial homeostasis is maintained by adult intestinal stem cells, which, alongside Paneth cells, appear after birth in the neonatal period. We aimed to identify regulators of neonatal intestinal epithelial development by testing a small library of epigenetic modifier inhibitors in Paneth cell-skewed organoid cultures. We found that lysine-specific demethylase 1A (<i>Kdm1a/Lsd1</i>) is absolutely required for Paneth cell differentiation. <i>Lsd1</i>-deficient crypts, devoid of Panet  ...[more]
