show Abstracthide AbstractArid1a, a subunit of the SWI/SNF chromatin remodeling complex, have been reported in multiple human cancers, however, its functional role in intestinal homeostasis remains unclear. To investigate the role of Arid1a in murine intestine, we have employed ChIP experiments in intestinal spheroid cells generated from crypt cells of wild type mice. ChIP assay revealed that Arid1a binds directly to the Sox9 promoter to support its expression. Overall design: We used intestinal spheroid cells generated from crypt cells of wild type mice.
