    Multi-omic mapping shows that group 3 and group 4 medulloblastomas have a common, human-specific developmental origin in the cerebellar rhombic lip, providing a basis for their ambiguous molecular features and overlapping anatomical location, and for the difficulty of modelling these tumours in mice.

    The ability of retrotransposons to mobilize and insert into genes presents a challenge to a cell needing to maintain its genomic integrity. These authors have studied retrotransposition in embryonic carcinoma-derived cells. On insertion into DNA, the retrotransposon is quickly silenced, but the retrotransposon-specificity of this process implies that multiple silencing mechanisms may exist. Once cells differentiate, the ability to silence newly introduced retrotransposons is lost but previously inactivated retrotransposons remain inactive.
