Hypothesis
Boundary cells must be refractory to the Wg signal for stable dorsal-ventral boundary formation.
Conclusion
The study demonstrates that the activity of the Notch target gene cut is essential for maintaining the stability of the dorsal-ventral boundary in Drosophila wing development.
Supporting Evidence
- The study presents evidence that boundary cells must be refractory to the Wg signal for stable Notch activation.
- Mathematical modeling was used to predict the behavior of the gene regulatory network.
- In vivo experiments confirmed the necessity of the cut gene for repressing Wg target gene expression in boundary cells.
Takeaway
This research shows that certain cells in the Drosophila wing need to ignore a specific signal to keep their boundaries stable during development.
Methodology
The study used a combination of mathematical modeling and both in silico and in vivo experiments to analyze the gene regulatory network.
