Disease relevance of ASCL2

 

Psychiatry related information on ASCL2

  • The data suggest that a complex interplay of activators (Hash-2, HEB) and repressors (Stra13, I-mfa) could be involved in extravillous trophoblast differentiation whereas downregulation of Id proteins could play a role in syncytialisation [5].

Regulatory relationships of ASCL2

  • The expression of proprotein convertase PACE4 is highly regulated by Hash-2 in placenta: possible role of placenta-specific basic helix-loop-helix transcription factor, human achaete-scute homologue-2 [12].
  • These findings suggest that Mash-2 may serve as a hypoxia-induced transcription factor that prevents differentiation to syncytiotrophoblast and aromatase induction in human trophoblast cultured under low O2 conditions [4].
