Disease relevance of Hnf4a

  • 5. HNF-4 mRNA was first detected in embryonic tissues at day 8.5, in the liver diverticulum and the hindgut [1].
  • Of these, only HNF4alpha (nuclear receptor 2A1) and HNF1alpha appear to be correlated with the differentiated phenotype of cultured hepatoma cells [2].
  • The disease maturity-onset diabetes of the young (MODY) is a genetically heterogeneous monogenic form of non-insulin-dependent (type 2) diabetes mellitus (NIDDM), characterized by early onset, usually before 25 years of age and often in adolescence or childhood, and by autosomal dominant inheritance [3].
  • HNF3 and HNF4 synergistically activate DHBV pregenomic RNA synthesis and viral replication [4].
  • Hepatocyte nuclear factor 4 (HNF4) binding to the proximal nuclear hormone receptor recognition sequence in the nucleocapsid promoter appears to limit RNA synthesis from the precore transcription initiation site [5].

Associations of Hnf4a with chemical compounds

  • Hepatocyte nuclear factor 4 (HNF-4) is a liver-enriched transcription factor and a member of the steroid hormone receptor superfamily [10].
  • TCPOBOP, a CAR agonist that increases the interaction of CAR with coactivators, potentiated CAR inhibition of HNF-4 transactivation [14].
  • Here, it is shown that CBP can acetylate hepatocyte nuclear factor-4 (HNF-4), a member of the nuclear hormone receptor family, at lysine residues within the nuclear localization sequence [15].
  • We have also identified the mutation in the HNF-1alpha gene in the Jutland pedigree, one of the original MODY pedigrees reported in the literature, as being a T-->G substitution in codon 241, resulting in the replacement of a conserved Cys by Gly (C241G) [16].
  • Phosphoenolpyruvate carboxykinase (GTP): characterization of the human PCK1 gene and localization distal to MODY on chromosome 20 [17].
 

Physical interactions of Hnf4a

 

Regulatory relationships of Hnf4a

  • Consistent with our earlier finding that HNF-6 stimulates the hnf4 and hnf3beta gene promoters, GH treatment of hypophysectomized rats increased the liver concentration of HNF-4 and HNF-3beta mRNAs [19].
  • GATA6 regulates HNF4 and is required for differentiation of visceral endoderm in the mouse embryo [8].
  • It appears, therefore, that HNF-4 activates the hepatic transcription of Cyp2a-4 gene through its direct binding to the regulatory element regardless of the methylation at position -50 [20].
 

Other interactions of Hnf4a

  • Taken together, these data suggest a model in which GATA6 lies upstream of HNF4 in a transcriptional cascade that regulates differentiation of the visceral endoderm [8].
  • Analysis of differentiation markers confirms that vHNF1 is part of a genetic network that directs the expression of HNF4 and downstream endodermal genes [21].
  • Transcriptional regulation by HNF-4 of the steroid 15alpha-hydroxylase P450 (Cyp2a-4) gene in mouse liver [20].
  • At later times HNF-4 transcripts were observed in the mesonephric tubules, pancreas, stomach, and intestine and, still later, in the metanephric tubules of the developing kidney [1].
  • HNF-4 could play an important role in the formation and function of visceral yolk sac and in the development of the liver and kidney since its mRNA, as determined by in situ hybridization, appears upon primary differentiation of these organs [22].
