Forkhead box A2 regulates biliary heterogeneity and senescence during cholestatic liver injury in mice‡.

ABSTRACT: Biliary-committed progenitor cells (small mouse cholangiocytes; SMCCs) from small bile ducts are more resistant to hepatobiliary injury than large mouse cholangiocytes (LGCCs) from large bile ducts. The definitive endoderm marker, forkhead box A2 (FoxA2), is the key transcriptional factor that regulates cell differentiation and tissue regeneration. Our aim was to characterize the translational role of FoxA2 during cholestatic liver injury. Messenger RNA expression in SMCCs and LGCCs was assessed by polymerase chain reaction (PCR) array analysis. Liver tissues and hepatic stellate cells (HSCs) from primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC) patients were tested by real-time PCR for methylation, senescence, and fibrosis markers. Bile duct ligation (BDL) and mu
