DKK1 and neuroblastoma: Downregulation of linc00467 in NB cells led to reduced cell viability and increase in apoptosis via activation of the tumor suppressor gene DKK1, suggesting that linc00467 plays an important role in tumorigenesis through reducing the activity of DKK1. Although, it regulates cell viability and apoptosis in NB cells, its prognostic value in NB risk assessment is unclear.
