HSD17B2 and Patent ductus arteriosus: The role for HNF1A in the exocrine pancreas is less clear, and compared to islet and liver cells in the latter study, we only identified 11 overlapping HNF1A upregulated genes (ANXA4, CEACAM1, CHKA, DPP4, HNF4A, HSD17B2, LGALS3, MTMR11, NR0B2, SLC16A5, TM4SF4), suggesting distinct activity for HNF1A in PDA compared to either β cells or the liver.
