FOXA2 regulates a network of genes involved in critical functions of intestinal epithelia

ABSTRACT: Background and Aims: The forkhead box A (FOXA) family of pioneer transcription factors is critical for the development of many endoderm-derived tissues including the lung and the liver. Here we investigate the role of FOXA2 in regulating intestinal epithelial cell function. Methods: ChIP-seq was used to identify FOXA2 binding sites genome-wide. Targets of FOXA2 were validated using ChIP-qPCR and siRNA-mediated depletion of FOXA1/2 followed by RT-qPCR. A luciferase-based assay was used to measure intracellular cAMP after FOXA1/2 modulation.Results: Peaks of FOXA2 occupancy were frequent at loci contributing to gene ontology pathways of regulation of cell migration, cell motion, and plasma membrane function. Depletion of both FOXA1 and FOXA2 led to a significant reduction in the expression
