| Outline of Final Research Achievements |
There are growing evidence showing that “Cell Competition”, a struggle for existence in multicellular communities, positively and negatively regulates cancer development and progression. However, the molecular mechanism of cell competition is still unclear. In this study, by using Gal4/UAS system in Drosophila imaginal epithelia, we established a novel model system for cell competition, in which cell competition occurs continuously, enabling us to detect cell competition more easily. We found by using this model system that Wingless signaling (a mammalian Wnt homolog) regulate cell competition triggered by differential expression level of ribosomal proteins.
