    Rev7 and 53BP1/Crb2 prevent RecQ helicase-dependent hyper-resection of DNA double-strand breaks

    Bryan A Leland et al.
    A single-cell assay reveals that the genetic rewiring that underlies PARP inhibitor resistance drives altered DNA double-strand break end resection pathway choice.

    Targeting of the Fun30 nucleosome remodeller by the Dpb11 scaffold facilitates cell cycle-regulated DNA end resection

    Susanne CS Bantele et al.
    Chromatin remodelling is a key bottleneck to DNA end resection, the first and committed step of homologous recombination.

    Major satellite repeat RNA stabilize heterochromatin retention of Suv39h enzymes by RNA-nucleosome association and RNA:DNA hybrid formation

    Oscar Velazquez Camacho et al.
    An RNA-mediated mechanism that stabilizes association of the Suv39h enzymes at mouse heterochromatin is defined.

    Structural basis for DNA 5´-end resection by RecJ

    Kaiying Cheng et al.
    A structural investigation reveals details of the mechanism by which the nuclease RecJ processes DNA ends to repair double strand breaks.

    The mobility of packaged phage genome controls ejection dynamics

    Alex Evilevitch
    Temperature and ionic conditions control the mechanical properties of virally encapsidated DNA and act as a switch between synchronized and desynchronized genome ejection dynamics in a phage population.

    The mechanism of variability in transcription start site selection

    Libing Yu et al.
    Variability in bacterial transcription start site selection involves DNA “scrunching” and “anti-scrunching,” which may represent a general mechanism for start site selection in all organisms.

    Target DNA bending by the Mu transpososome promotes careful transposition and prevents its reversal

    James R Fuller, Phoebe A Rice
    Biochemical data demonstrate that the conformation of the target site DNA can dramatically modulate the kinetics and directionality of the otherwise isoenergetic transposition reaction of DDE transposases.

    Forniceal deep brain stimulation induces gene expression and splicing changes that promote neurogenesis and plasticity

    Amy E Pohodich et al.
    Forniceal deep brain stimulation is a promising treatment for several neuropsychiatric disorders as it upregulates synaptic and neurogenesis-associated genes, normalizes genes misregulated in Rett syndrome mice, and regulates genes altered in intellectual disability and major depression.

    The S-phase-induced lncRNA SUNO1 promotes cell proliferation by controlling YAP1/Hippo signaling pathway

    Qinyu Hao et al.
    Cell cycle phase-specifically induced long non-coding RNAs regulate cell proliferation by modulating crucial cell signaling pathways.

    Molecular evidence of hybridization between pig and human Ascaris indicates an interbred species complex infecting humans

    Alice Easton et al.
    Comparative phylogenomic analyses based on a new reference-quality human Ascaris genome assembly reveals a pig/human interbred species complex with implications for Ascaris control worldwide.
