| Outline of Final Research Achievements |
The Shh locus provides a good model to study gene regulatory by tissue-specific enhancers residing at very remote regions from the Shh promoter. Our next-generation sequencing analysis revealed dynamic chromosomal architecture around the Shh locus, which is possibly responsible for the promoter-enhancer interactions in the mouse embryo. We also demonstrated different sizes of interactome between the Shh gene and neighboring genes or genomic segments. In addition, we found a phylogenetic boundary of evolutionary conservation of a larynx Shh enhancer by genome comparison among different vertebrate species. Euteleost has evolved a novel endodermal enhancer that functionally corresponds to the larynx enhancer in terrestrial animals.
