One of the most important decisions a cell can make during both developmental and pathological processes is to choose between continued survival and death. For the normal processes of life to occur, cell survival mechanisms must function to oppose cell death. The mechanisms that distinguish between cell death and cell survival and between aspects of cell growth, the increase in cell size and number, are of fundamental importance to many aspects of biology. The origins of many human diseases may be due to errors in these basic biological functions. Drosophila has become an ideal model organism in which to manipulate programmed cell death.
1) to understand the phenomenon of cell survival and the signaling mechanisms that prevent cell death 2) to develop an understanding of the subtle cellular decisions that control and differentiate between cell survival and cell growth 3) to identify and characterize additional components of the akt signaling pathway especially the biologically significant transcriptional targets of foxo, and to discover the extent of the biological consequences of these genes 4) to develop models of neurodegenerative diseases such as Parkinson's disease
