Loss of hepatic HNF4α expression is frequently observed in end-stage liver disease (ESLD) and associated with loss of vital liver functions and thus increases mortality. Loss of HNF4α expression is mediated by inflammatory cytokines such as TGF-β. However, details of how HNF4α is suppressed are largely unknown to date. This study reports that TGF-β does not directly inhibit HNF4α, but contributes to its transcriptional regulation by SMAD2/3 recruiting acetyltransferase CBP/p300 to the HNF4α promoter...
