Nerve growth factor (NGF) is required for the survival of developing sympathetic and sensory neurons. In the absence of NGF, these neurons undergo protein synthesis-dependent apoptosis. Ten years have gone by since the first reports of specific genes being upregulated during NGF deprivation-induced cell death. Over the last decade, a few additional genes (DP5, Bim, SM-20) have been added to a list that began with cyclin D1 and c-jun. In this chapter, we discuss the evidence that these genes act as regulators of neuronal cell death. We also suggest a hypothesis for how one gene, SM-20, may function to suppress a self-protection mechanism in NGF-deprived neurons. |
