Histone acetyltransferases and are paralogs highly expressed in the intestinal epithelium, but their functions are not well understood. In this study, double knockout of murine genes in the intestinal epithelium was lethal, resulting in robust activation of interferon signaling and interferon-associated phenotypes including the loss of intestinal stem cells. Use of pharmacological agents and sterile organoid cultures indicated a cell-intrinsic double-stranded RNA trigger for interferon signaling.
