Cdc14B/Cyclin B1 signaling modulates the pathogenesis of sonic hedgehog subtype medulloblastoma.

Medulloblastoma (MB) is a severe malignancy of the central nervous system that predominantly occurs in the cerebellum of children. Overactivation of the sonic hedgehog (Shh) signaling pathway is the primary cause of the development and progression of Shh subtype MB, although the detailed mechanisms underlying this process remain largely elusive. In this study, we discovered that Shh can promote proliferation in MB cells through non-canonical Hedgehog signaling.
