    Chromosome territory formation attenuates the translocation potential of cells

    Leah F Rosin et al.
    The translocation potential of cells can be modulated by Condensin II activity during interphase.

    Interferon alpha-inducible protein 6 regulates NRASQ61K-induced melanomagenesis and growth

    Romi Gupta et al.
    The protein IFI6 regulates DNA replication via the transcription factor E2F2, which is necessary for transformation and growth of melanomas induced by the NRASQ61K mutant oncogene product.

    SETD2 is required for DNA double-strand break repair and activation of the p53-mediated checkpoint

    Sílvia Carvalho et al.
    The involvement of SETD2 in an important DNA repair pathway could explain the high frequency of SETD2 mutations in several cancers and may provide an alternative mechanism to evade the p53-mediated checkpoint.

    Direct observation of frequency modulated transcription in single cells using light activation

    Daniel R Larson et al.
    Steroid hormone receptors control the expression of their target genes through a digital on-off switch in individual cells, which leads to an analogue dose-response relationship at the level of the whole organism.

    Distinct roles for S. cerevisiae H2A copies in recombination and repeat stability, with a role for H2A.1 threonine 126

    Nealia CM House et al.
    Despite differing by only one amino acid in the C-terminal tail, copy 1 of yeast histone 2A has a repair-specific role not shared by copy 2.

    Extensive cargo identification reveals distinct biological roles of the 12 importin pathways

    Makoto Kimura et al.
    Transport-based high-throughput identification of cargo proteins specific to all 12 human importin-β family nuclear import receptors revealed biological processes that the cargo cohorts of each receptor are involved in.

    The Chd1 chromatin remodeler shifts hexasomes unidirectionally

    Robert F Levendosky et al.
    Oriented hexasomes can be generated using the Widom 601 positioning sequence, which enables straightforward production of nucleosomes with asymmetrically modified H2A/H2B dimers.

    TGF-β reduces DNA ds-break repair mechanisms to heighten genetic diversity and adaptability of CD44+/CD24− cancer cells

    Debjani Pal et al.
    Phenotypic diversity and cell state transition (i.e., acquisition of a CD44+/CD24- cell state or exposure to TGF-beta) can spur intra-tumor genetic heterogeneity and contribute to acquired resistance.

    Aurora-A mediated histone H3 phosphorylation of threonine 118 controls condensin I and cohesin occupancy in mitosis

    Candice L Wike et al.
    A histone modification that alters the nucleosome structure occurs in mitosis and promotes chromosome packaging and the timely removal of condensin I and cohesion, to achieve chromosome segregation.

    Epigenetic silencing of a multifunctional plant stress regulator

    Mark Zander et al.
    Interplay between histone demethylation and chromatin remodeling shapes the chromatin environment of the essential stress regulator ETHYLENE-INSENSITIVE2.
