Abstract:
Transcription factors are expressed in a dynamic fashion both in time and space during brain development, and exert their roles by activating a cascade of multiple target genes. This implies that understanding the precise function of a transcription factor becomes a challenging task. In this review, we will focus on COUP-TFI (or NR2F1), a nuclear receptor belonging to the superfamily of the steroid/thyroid hormone receptors, and considered to be one of the major transcriptional regulators orchestrating cortical arealization, cell-type specification and maturation. Recent data have unraveled the multi-faceted functions of COUP-TFI in the development of several mouse brain structures, including the neocortex, hippocampus and ganglionic eminences. Despite NR2F1 mutations and deletions in humans have been linked to a complex neurodevelopmental disease mainly associated to optic atrophy and intellectual disability, its role during the formation of the retina and optic nerve remains unclear. In light of its major influence in cortical development, we predict that its haploinsufficiency might be the cause of other cognitive diseases, not identified so far. Mouse models offer a unique opportunity of dissecting COUP-TFI function in different regions during brain assembly; hence, the importance of comparing and discussing common points linking mouse models to human patients' symptoms.
Insights
Chicken ovalbumin upstream promoter transcription factor II (COUP-TFI) regulates brain development. Its role in retinal development is unclear, but mouse models suggest it may cause other cognitive diseases when deficient.
Area of Science:
- Neuroscience
- Developmental Biology
- Genetics
Background:
- Transcription factors orchestrate complex developmental processes like brain formation.
- COUP-TFI (NR2F1) is a key nuclear receptor regulating cortical development, cell specification, and maturation.
- Understanding transcription factor roles is challenging due to dynamic expression and multiple targets.
Purpose of the Study:
- To review the multifaceted functions of COUP-TFI in brain development.
- To explore the potential role of COUP-TFI in retinal and optic nerve formation.
- To investigate the link between COUP-TFI haploinsufficiency and cognitive diseases using mouse models.
Main Methods:
- Literature review of studies on COUP-TFI function in brain development.
- Analysis of existing data on NR2F1 mutations in human neurodevelopmental disorders.
- Comparative analysis of mouse models and human patient symptoms.
Main Results:
- COUP-TFI plays critical roles in the neocortex, hippocampus, and ganglionic eminences during development.
- Human NR2F1 mutations are associated with optic atrophy and intellectual disability.
- The specific role of COUP-TFI in retina and optic nerve development requires further investigation.
Conclusions:
- COUP-TFI is a crucial regulator of mammalian brain development.
- COUP-TFI haploinsufficiency may underlie currently unidentified cognitive disorders.
- Mouse models are essential for dissecting COUP-TFI functions and understanding human disease.
