Research Abstract |
Nerve growth factor(NGF) dependency is responsible for developmentally programmed cell death(PCD) of normal peripheral neurons as well as spontaneous regression of neuroblastoma(NB), a childhood solid tumor arising from sympathoadrenal lineage. However the molecular mechanism remains elusive. In this study, we found that the dependence receptor UNC5D was involved in NGF deprivation-induced cell death in neuroblastoma through the nuclear translocation of its intracellular fragment released by caspase 2/3.Our findings indicate that UNC5D may play a critical role in accelerating cell death during regression of neuroblastoma, which could be a tool to develop new therapeutic strategies against high-risk tumors.
