Abstract
The glial cell line-derived neurotrophic factor (GDNF) family of ligands play essential roles in promoting normal neural crest differentiation during embryogenesis, and, may have a therapeutic role in malignancies of neural crest origin, such as neuroblastoma. However, we report here that GDNF and neurturin blocked the growth inhibitory and neuritogenic effects of all-trans-retinoic acid in neuroblastoma cells in vitro. GDNF caused neuroblastoma cells to proliferate in the presence of a range of cytotoxic chemotherapeutic agents at low concentrations. Thus, our findings suggest a role for GDNF signaling in promoting resistance to differentiation or cytotoxic therapy of neuroblastoma, and, preclude their use in this neural crest tumor.
