    Super-resolution imaging of a 2.5 kb non-repetitive DNA in situ in the nuclear genome using molecular beacon probes

    Yanxiang Ni, Bo Cao ... Hanben Niu
    Molecular beacon based FISH shows the capability of visualizing a 2.5 kb non-repetitive genomic DNA sequence in situ in human or mouse nuclear genome at super resolution.

    Functional and mutational landscapes of BRCA1 for homology-directed repair and therapy resistance

    Rachel W Anantha, Srilatha Simhadri ... Bing Xia
    Systematic analyses of natural variants and artificial mutants establish functional landscapes of BRCA1 for homology-directed repair (HDR) and therapy resistance and identify the BRCA1-PALB2 interaction as a key control point for HDR pathway choice.

    Polo-like kinase-dependent phosphorylation of the synaptonemal complex protein SYP-4 regulates double-strand break formation through a negative feedback loop.

    Saravanapriah Nadarajan, Talley J Lambert ... Monica P Colaiácovo
    PLK-1/2-mediated SYP-4 phosphorylation is dependent on crossover precursor formation, triggering a switch in the dynamic state of the synaptonemal complex that reduces the formation of further double-strand breaks at late meiotic prophase.

    Meiosis: Stopping chromosomes from breaking bad

    Rima Sandhu, G Valentin Börner
    The scaffolding that holds chromosome pairs together plays a key role in limiting the levels of double-strand breaks.

    sRNA-mediated activation of gene expression by inhibition of 5'-3’ exonucleolytic mRNA degradation

    Sylvain Durand, Frédérique Braun ... Ciarán Condon
    Small regulatory RNAs are able to modulate mRNA degradation rates by controlling access to the 5' end of mRNAs in bacteria.

    Synthetically modified guide RNA and donor DNA are a versatile platform for CRISPR-Cas9 engineering

    Kunwoo Lee, Vanessa A Mackley ... Niren Murthy
    The guide RNA and donor DNA of the CRISPR/Cas system tolerate large chemical modifications and can be engineered for enhanced delivery and gene editing.

    Atrophin controls developmental signaling pathways via interactions with Trithorax-like

    Kelvin Yeung, Ann Boija ... Helen McNeill
    ChIP-seq and phenotypic analyses reveal Atrophin from Drosophila directly regulates Notch and Dpp signaling components, and engrailed gene expression, via interactions with GAGA Factor.

    Global reorganisation of cis-regulatory units upon lineage commitment of human embryonic stem cells

    Paula Freire-Pritchett, Stefan Schoenfelder ... Mikhail Spivakov
    Promoter interactome maps in human embryonic stem cells (ESCs) and ESC-derived early neuroectodermal progenitors link distal enhancers to putative target genes, reveal lineage-specific cis-regulatory architecture and shed light on the logic of gene regulation by multiple enhancers.

    Histone gene replacement reveals a post-transcriptional role for H3K36 in maintaining metazoan transcriptome fidelity

    Michael P Meers, Telmo Henriques ... A Gregory Matera
    Post-translational modification of histone H3K36 is not required to suppress cryptic transcription initiation or to include alternative exons in Drosophila; instead it promotes expression of active genes by stimulating polyadenylation.

    Fail-safe control of translation initiation by dissociation of eIF2α phosphorylated ternary complexes

    Martin D Jennings, Christopher J Kershaw ... Graham D Pavitt
    Phosphorylated translation initiation factor eIF2, a potent inhibitor of protein synthesis in eukaryotic cells, is also inhibitory to protein synthesis when bound to GTP and initiator tRNA broadening the reach and immediacy of eIF2-mediated control.
