Olig1 function is required for oligodendrocyte differentiation in the mouse brain.
Oligodendrocyte differentiation and myelination are tightly regulated processes orchestrated by a complex transcriptional network. Two bHLH transcription factors in this network, Olig1 and Olig2, are expressed exclusively by oligodendrocytes after late embryonic development. Although the role of Olig2 in the lineage is well established, the role of Olig1 is still unclear. The current studies an...
متن کاملOlig1 Function Is Required to Repress Dlx1/2 and Interneuron Production in Mammalian Brain
Abnormal GABAergic interneuron density, and imbalance of excitatory versus inhibitory tone, is thought to result in epilepsy, neurodevelopmental disorders, and psychiatric disease. Recent studies indicate that interneuron cortical density is determined primarily by the size of the precursor pool in the embryonic telencephalon. However, factors essential for regulating interneuron allocation fro...
متن کاملImmunolocalization of the oligodendrocyte transcription factor 1 (Olig1) in brain tumors.
Recent in situ hybridization studies showed that mRNA levels of OLIG1 and OLIG2 transcription factors are elevated in oligodendrogliomas. We raised polyclonal antibodies against a synthetic peptide homologous to the human transcription factor Olig1 and studied by immunohistochemistry the expression of Olig1 in 84 brain tumors and in non-neoplastic brain tissues. All oligodendrogliomas, oligoast...
متن کاملOlig1 and Olig2 promote oligodendrocyte differentiation of neural stem cells in adult mice injured by EAE
Investigating neural stem cell plasticity in the hippocampal niche, we demonstrate that retroviral forced expression of Mash1 (Mammalian Achaete-Scute Homolog 1), Olig1 (Oligodendrocyte transcription factor 1), and Olig2 (Oligodendrocyte transcription factor 2) genes, transcription factors involved in enhanced oligodendrogenesis, can contribute to directing the differentiation of adult subventr...
متن کاملInterplay between H1 and HMGN epigenetically regulates OLIG1&2 expression and oligodendrocyte differentiation
An interplay between the nucleosome binding proteins H1 and HMGN is known to affect chromatin dynamics, but the biological significance of this interplay is still not clear. We find that during embryonic stem cell differentiation loss of HMGNs leads to down regulation of genes involved in neural differentiation, and that the transcription factor OLIG2 is a central node in the affected pathway. ...
