Disease relevance of Nr4a2

 

High impact information on Nr4a2

  • Here we demonstrate the presence of endogenous RXR ligands in the embryonic central nervous system (CNS) and show that they can activate heterodimers formed between RXR and the orphan NR Nurr1 in vivo [5].
  • Induction of a midbrain dopaminergic phenotype in Nurr1-overexpressing neural stem cells by type 1 astrocytes [6].
  • This process requires both the overexpression of the nuclear receptor Nurr1 and factors derived from local type 1 astrocytes [6].
  • Here we use undifferentiated progenitors to probe the events leading to the dopaminergic phenotype and find that the influences of Nurr1 can be temporally and mechanistically uncoupled from the patterning influences of sonic hedgehog and FGF-8 or the more generic process of neuronal differentiation itself [7].
  • In gain-of-function experiments, Nurr1 is able to activate transcription of the tyrosine hydroxylase gene by binding a response element within a region of the tyrosine hydroxylase promoter necessary for midbrain-specific expression [7].
 

Biological context of Nr4a2

 

Anatomical context of Nr4a2

  • A full-length cDNA clone of RNR-1 encodes a 66-kDa, 597-amino acid protein as verified by in vitro translation in reticulocyte lysate [8].
  • In particular, the NGFI-B ligand-binding domain (LBD) exhibits only modest activity in cell lines in which the Nurr1 LBD strongly activates transcription [9].
  • The transcription factor/nuclear receptor Nurr1 is essential for the differentiation of midbrain dopaminergic neurones [11].
  • Rapid increase of Nurr1 expression in the substantia nigra after 6-hydroxydopamine lesion in the striatum of the rat [12].
  • Additionally, we found that Nurr1 is expressed in brain regions that have not been previously reported, such as striatum, septum, and superior colliculus [12].
 

Associations of Nr4a2 with chemical compounds

 

Regulatory relationships of Nr4a2

  • In the present study, we first demonstrate in the adult rat that the orphan nuclear receptor Nurr1 is coexpressed in latexin-expressing neurons located in layer V, sublayer VIa, and the white matter of the lateral sector of the neocortex, and also in latexin-negative early born neurons in sublayer VIb of the entire neocortex [14].
