A day in the life of chromatin: how enhancer–promoter loops shape daily behavior
How daily changes in DNA loops between gene switches and starters influence behavior
AI simplified
Abstract
Disruption of enhancer-promoter contacts within chromatin leads to an advance in the 'wake-up' time of mice.
- Clock genes encode transcription factors that are expressed across various tissues.
- Time of day-dependent changes in chromatin are linked to core clock oscillations.
- The assembly of active chromatin domains involves the sequential recruitment of core clock transcription factors daily.
- Waking up is associated with significant changes in the three-dimensional arrangement of genes within cells.
