    Neural stem cell-encoded temporal patterning delineates an early window of malignant susceptibility in Drosophila

    Karine Narbonne-Reveau, Elodie Lanet ... Cédric Maurange
    Sequentially expressed temporal transcription factors in neural stem cells during early development determine which progeny can undergo malignant transformation upon dedifferentiation.

    RUNX1 marks a luminal castration-resistant lineage established at the onset of prostate development

    Renaud Mevel, Ivana Steiner ... Georges Lacaud
    The transcription factor RUNX1 marks a distinct lineage of luminal castration-resistant prostate cells established early during development and enriched in the periurethral region of adult mouse prostate.

    Coopted temporal patterning governs cellular hierarchy, heterogeneity and metabolism in Drosophila neuroblast tumors

    Sara Genovese, Raphaël Clément ... Cédric Maurange
    About twenty temporal patterning genes are identified that drive an irreversible differentiation trajectory governing the heterogeneity and proliferative properties of cells in neural tumors with an early developmental origin.

    Targets and genomic constraints of ectopic Dnmt3b expression

    Yingying Zhang, Jocelyn Charlton ... Alexander Meissner
    Ectopic expression of Dnmt3b leads to wide-spread CpG island hypermethylation that is largely defined by chromatin state and has some distinct features when compared to the cancer methylome.

    Reassessment of weak parent-of-origin expression bias shows it rarely exists outside of known imprinted regions

    Carol A Edwards, William MD Watkinson ... Anne C Ferguson-Smith
    Genes with parent-of-origin specific expression are not as numerous as previously reported and validated parentally-biased expressed genes tend to be peripheral to known imprinted domains indicating shared regional control.

    A network of epigenetic modifiers and DNA repair genes controls tissue-specific copy number alteration preference

    Dina Cramer, Luis Serrano, Martin H Schaefer
    The genetic background of a cancer cell and the chromatin organization of the tissue-of-origin impact the amount, length and position of somatic copy number alterations in cancer.

    Rapid DNA replication origin licensing protects stem cell pluripotency

    Jacob Peter Matson, Raluca Dumitru ... Jeanette Gowen Cook
    The unique cell cycle variations of pluripotent stem cells ensures that the first step in DNA replication is particularly fast and this rapid rate, in turn, restrains early differentiation.

    Integrative analysis of DNA replication origins and ORC-/MCM-binding sites in human cells reveals a lack of overlap

    Mengxue Tian, Zhenjia Wang ... Chongzhi Zang
    The ~20,000 origins of replication in human cell lines that are reproducibly identified by multiple techniques in multiple cell lines are distant from known origin recognition complex and MCM2-7-binding sites.
