GNRHR and neuroblastoma: This region also contains binding sites for ZNF143 (a transcription factor which interacts with a puberty-related factor, LIN28B, in neuroblastoma cells (50)), JUND (JunD binds to Gnrhr AP-1 site in mouse gonadotrope-derived αT3-1 cells (51) and is expressed in the mouse olfactory bulb (52)), GATA2 and GATA3 (crucial for neurogenesis and expressed in the olfactory bulbs (53)) and CEBPB (Cebpb in rats is expressed in the olfactory bulbs and olfactory ensheathing cells (54) and is known to be an upstream transcriptional regulator of Gnrh1 in mice (55)).
