    Multiple kinases inhibit origin licensing and helicase activation to ensure reductive cell division during meiosis

    David V Phizicky, Luke E Berchowitz, Stephen P Bell
    Meiotic cells inhibit two distinct steps of replisome assembly with multiple kinases to prevent DNA replication between Meiosis I and Meiosis II.

    In vivo analysis reveals that ATP-hydrolysis couples remodeling to SWI/SNF release from chromatin

    Ben C Tilly, Gillian E Chalkley ... C Peter Verrijzer
    Visualization of BRM remodelers engaging their endogenous genomic targets revealed highly transient and dynamic interactions with chromatin, which are fueled by ATP-hydrolysis.

    The kleisin subunit controls the function of C. elegans meiotic cohesins by determining the mode of DNA binding and differential regulation by SCC-2 and WAPL-1

    Maikel Castellano-Pozo, Georgios Sioutas ... Enrique Martinez-Perez
    Meiosis-specific cohesin complexes differing in their kleisin subunit display different chromosome binding dynamics and perform specialised functions in sister chromatid cohesion, chromosome axis organisation, and double-strand break repair.

    Single-molecule observation of ATP-independent SSB displacement by RecO in Deinococcus radiodurans

    Jihee Hwang, Jae-Yeol Kim ... Nam Ki Lee
    RecO efficiently displaces SSB from ssDNA without consuming ATPs using its two DNA-binding sites, even though SSB binds to ssDNA approximately 300 times more strongly than RecO does.

    A conserved Mcm4 motif is required for Mcm2-7 double-hexamer formation and origin DNA unwinding

    Kanokwan Champasa, Caitlin Blank ... Stephen P Bell
    Analysis of an essential motif in Mcm4 provides insights into replicative helicase double-hexamer formation and the first step requiring this intermediate during replication initiation.

    Epigenetic analysis of Paget’s disease of bone identifies differentially methylated loci that predict disease status

    Ilhame Diboun, Sachin Wani ... Omar ME Albagha
    PDB-associated differences in DNA methylation are reproducible and reflect key environmental modulators of bone homeostasis including viral processes, vitamin D metabolism, as well as mechanical sheer load.

    Unexpected sequences and structures of mtDNA required for efficient transcription from the first heavy-strand promoter

    Akira Uchida, Divakaran Murugesapillai ... Craig E Cameron
    Hypervariable regions of mtDNA contribute to transcriptional regulation by serving as sites for TFAM binding and looping.

    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.

    Transcription-coupled genetic instability marks acute lymphoblastic leukemia structural variation hotspots

    Merja Heinäniemi, Tapio Vuorenmaa ... Olli Lohi
    Convergent transcription and stalling of transcription are enriched at DNA breakpoints found in acute lymphoblastic leukemia and associate with DNA structures and sequences that mediate genetic instability.

    CTCF and cohesin regulate chromatin loop stability with distinct dynamics

    Anders S Hansen, Iryna Pustova ... Xavier Darzacq
    Single-molecule imaging of CTCF and cohesin in live cells suggests that chromatin loops are dynamic structures that frequently form and fall apart.
