Abstract
Hepatocyte nuclear factor 4 α (HNF4α) is a highly conserved member of the nuclear
receptor superfamily expressed at high levels in the liver, kidney, pancreas, and
gut. In the liver, HNF4α is exclusively expressed in hepatocytes, where it is indispensable
for embryonic and postnatal liver development and for normal liver function in adults.
It is considered a master regulator of hepatic differentiation because it regulates
a significant number of genes involved in hepatocyte-specific functions. Loss of HNF4α
expression and function is associated with the progression of chronic liver disease.
Further, HNF4α is a target of chemical-induced liver injury. In this review, we discuss
the role of HNF4α in liver pathophysiology and highlight its potential use as a therapeutic
target for liver diseases.
