GDNF/RET activate Hedgehog/GLI signaling in neuroblastoma cells.
GDNF/RET/AKT/GSK3β signaling module promotes proteolytic formation of GLI activators.
RET induces the neuroblastoma cell proliferation and tumor growth through Hedgehog pathway.
Targeting Hedgehog pathway is a rational approach for the therapy of neuroblastoma.
