LIN28B and neuroblastoma: The RNA‐binding protein LIN28B is typically expressed during embryogenesis and plays a crucial role in maintaining the identity of stem and progenitor cells primarily by inhibiting the biogenesis of the let‐7 miRNA family.[4] In addition to its physiological function, LIN28B has been implicated in the development of various cancer types, including neuroblastoma.[28] Neuroblastoma is a pediatric solid tumor arising from a transient population of stem cells, the NC deriving ones.
