Think Inside the BOCs: A Mechanism Underlying Medulloblastoma Progression

Approximately one-third of medulloblastoma cases are associated with genetic lesions of Hedgehog (Hh) signaling pathway components. In this issue of Developmental Cell, Mille et al. (2014) show that the Hh coreceptor Boc functions specifically in the progression of early- to advanced-stage medulloblastoma by promoting Cyclin D1-dependent DNA damage and genomic instability
