TBXT, T-box transcription factor T
Disease Roles
Brachyury Overview
Brachyury, encoded by the TBXT gene, is a transcription factor crucial for embryonic development, particularly mesoderm and notochord formation. Its overexpression is strongly associated with chordoma, a rare spinal tumor, and variants can increase the risk of neural tube defects. Brachyury also contributes to tumor metastasis via epithelial-mesenchymal transition (EMT), making it an emerging target for cancer therapy research.
Mechanism of Action
Inhibition of Brachyury transcriptional activity (potential future therapies)
Biological Functions
Mesoderm formation
Notochord development
Transcriptional regulation
Cell movement during gastrulation
Axis formation
Neural tube development
Disease Associations
Chordoma
Neural tube defects
Cancer
Tumor metastasis
Safety Considerations
- Off-target effects on other T-box genes
- Potential developmental toxicity if targeted during embryogenesis
- Induction of other oncogenic pathways
