A developmental program drives aggressive embryonal brain tumors

Embryonal tumors with multilayered rosettes (ETMRs) are primitive neuroectodermal tumors arising in infants. A new study shows that these tumors are universally driven by fusion of the promoter of a gene with brain-specific expression, TTYH1, to C19MC, the largest human microRNA cluster, activating a fetal neural development program.
