Disease relevance of OLIG2

 

Psychiatry related information on OLIG2

  • It was hypothesized a priori that OLIG2 and OLIG1 were associated with OCD regardless of the presence of comorbid Tourette disorder (TD), but not with TD alone [4].
  • Finally, the formation of oligodendrocytes is triggered by an increase in the activity of bHLH factors Olig1 and Olig2 that may be coupled with a decrease in Id activity [5].
 

High impact information on OLIG2

  • By temporally selective interactions with other transcription factors, Olig2 first directs motor neuron fate and later switches to promoting oligodendrocyte production [6].
  • The bHLH repressor Olig2 participates in the transcriptional code governing cell fate specification in the ventral spinal cord [6].
  • At later stages, NFIA promotes migration and differentiation of astrocyte precursors, a function that is antagonized in oligodendrocyte precursors by Olig2 [7].
  • Functional analysis of PDGF signaling in these neural progenitors resonates in provocative ways with an older body of literature on PDGF autocrine loops in malignant glioma and with more recent observations on the bHLH transcription factor Olig2 [8].
  • OLIG2-positive cells corresponding to neoplastic oligodendrocytes were present in all oligodendrogliomas and oligoastrocytomas [3].
