| Outline of Final Research Achievements |
We previously found that neoplastic tumors in Drosophila imaginal discs always arise from the unique intrinsic structures "tumor hotspots" in the epithelial continuum. In the present study, we investigated the genetic mechanism underlying the cellular architecture of the tumor hotspots and the initiation of tumor formation, by the hydrodynamic modeling of epithelia we developed. We identified multiple candidate genes and enhancer elements potentially involved in the formation of hotspots. Furthermore, we found signaling pathways required for the delamination and proliferation of tumorigenic mutant epithelial cells at the hotspots.
