Regulation of Cell Death by The Drosophila ING Proteins (Master's thesis, University of Calgary, Calgary, Canada).

INGs are subunits of histone deacetylase (HDAC) and histone acetyltransferase (HAT) complexes. The Drosophila genome encodes 3 ING homologues, dING 2, 3 and 4. In this research, I showed that overexpression of dING2 leads to smaller tissue and clone size in Drosophila. dING2 was sufficient to induce caspase-dependent but p53-independent cell death, which promoted expression of the pro-apoptotic gene, reaper. Experiments conducted on polyploid tissues revealed that clonal overexpression of dING2 had little effect in cells in the larval fat body, but resulted in smaller salivary glands. My experiments established that overexpression of dING3 induces caspase-dependent cell death. However, neither dING2 nor dING3 is required for IR-induced apoptosis. This work should provide valuable insights into the role of INGs in apoptosis.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
