Oligodendrocyte transcription factor 2

This gene encodes a basic helix-loop-helix transcription factor which is expressed in oligodendroglial tumors of the brain. The protein is an essential regulator of ventral neuroectodermal progenitor cell fate. The gene is involved in a chromosomal translocation t(14;21)(q11.2;q22) associated with T-cell acute lymphoblastic leukemia. Its chromosomal location is within a region of chromosome 21 which has been suggested to play a role in learning deficits associated with Down syndrome. [provided by RefSeq, Jul 2008] (from NCBI)

Jiang et al., Chongqing, China. In Brain Res, 19 Dec 2015
The transcription factors olig1 and olig2, which play crucial roles in regulating OPC proliferation, differentiation and remyelination, were up-regulated during the early phases (the acute and latent phases) followed by a sharp decline in their expression during the chronic and late chronic phases.

Kesari et al., San Diego, United States. In Oncotarget, 30 Nov 2015
We targeted the OLIG2 TF which is essential for GBM survival and growth, we hypothesized that small molecules able to fit each subpharmacophore would inhibit OLIG2 activation.

Primary diffuse leptomeningeal glioneuronal tumors.
Park et al., Seoul, South Korea. In Brain Tumor Pathol, Jan 2015
All three cases were diffusely positive for both GFAP and synaptophysin, and scattered positive for OLIG2 and NeuN, but negative for IDH-1 (H09).
Sonic hedgehog functions upstream of disrupted-in-schizophrenia 1 (disc1): implications for mental illness.
Wood et al., Sheffield, United Kingdom. In Biol Open, Dec 2014
We show that disc1 is prominently expressed in olig2-positive midline progenitor cells that are absent in smo mutants, while cyclopamine treatment blocks disc1 expression in these cells and mimics the effect of disc1 knock down on OPC specification.
Signaling molecules regulating phenotypic conversions of astrocytes and glial scar formation in damaged nerve tissues.

The transcription factors: STAT3, OLIG2, SMAD, NF-κB, and Sp1 have been suggested to play regulatory roles in astrocytic activation and glial scar formation.

Rowitch et al., Boston, United States. In Nat Rev Neurosci, 2012
