Differential role of HNF4α isoforms in colitis and colitis-associated colon cancer


ABSTRACT: Hepatocyte nuclear factor 4alpha (HNF4α) is a nuclear receptor with an emerging role in the gut. While HNF4α has been implicated in colitis and colon cancer in humans, deciphering its functional role is complicated by the existence of two promoters (P1 and P2) in theHNF4A gene that drive the expression of multiple isoforms in the adult intestine. In this study we investigate the roles of P1- and P2-driven HNF4α under conditions of homeostasis, colitis and colitis-associated colon cancer (CAC). P1- and P2-HNF4α are differentially expressed in the differentiated and proliferative compartments of the normal colonic crypt, respectively. Expression profiling of untreated exon swap mice suggests distinct functions of the isoforms that were corroborated in migration and ion transport assays.
