| Outline of Final Research Achievements |
Unwanted cells are induced cell death, then phagocytes recognize them using phagocytosis receptor(s) and engulfed. Our previous experiments showed that a Drosophila lacking phagocytosis receptors, Draper and integrin beta-nu, took longer time to develop into adults. This results hypothesized that phagocytosis receptor-mediated phagocytosis controlled ontogenetic growth. To be clear that, phagocytosing phagocyte was subjected to DNA microarray analysis and gel-shift assay. I found; 1) expression level of growth-related gene B was up-regulated, 2) amount of a repressor C which suppresses transcription of the gene B was decreased, and 3) another repressor A which suppresses transcription of the gene C was activated. These findings support the hypothesis.
