    A Plasmodium falciparum MORC protein complex modulates epigenetic control of gene expression through interaction with heterochromatin

    Maneesh Kumar Singh, Victoria Ann Bonnell ... Celia RS Garcia
    Multi-omic analyses reveal that the chromatin-associated microrchidia protein, MORC (PF3D7_1468100), at the blood stage of the human malaria parasite, Plasmodium falciparum, interacts with a range of nuclear proteins.

    Topological stress triggers persistent DNA lesions in ribosomal DNA with ensuing formation of PML-nucleolar compartment

    Alexandra Urbancokova, Terezie Hornofova ... Pavla Vasicova
    Chemotherapeutics altering DNA topology evoke RNA polymerase I inhibition, rDNA damage and consequent formation of PNAs that segregate persistent rDNA lesions from the active nucleolus, with implications for rDNA maintenance and design of new cancer treatment strategies targeting rDNA repair.

    On the pH-dependence of α-synuclein amyloid polymorphism and the role of secondary nucleation in seed-based amyloid propagation

    Lukas Frey, Dhiman Ghosh ... Jason Greenwald
    The amyloid polymorph selection that occurs during α-synuclein aggregation is dictated by environmental conditions, in particular pH, with the largest variety of structures being observed near neutral pH.

    Dependence of nucleosome mechanical stability on DNA mismatches

    Thuy TM Ngo, Bailey Liu ... Taekjip Ha
    The mechanical stability of a nucleosome is enhanced upon the introduction of a single base pair mismatch that makes DNA more bendable, with implications on mismatch repair in vivo.

    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.

    WRNIP1 prevents transcription-associated genomic instability

    Pasquale Valenzisi, Veronica Marabitti ... Annapaola Franchitto
    WRNIP1 has been identified as a pivotal factor in preventing the pathological persistence of R-loop-induced transcription-replication conflicts and the accumulation of DNA damage, thereby ensuring genome integrity.

    Disordered regions and folded modules in CAF-1 promote histone deposition in Schizosaccharomyces pombe

    Fouad Ouasti, Maxime Audin ... Francoise Ochsenbein
    Histone, PCNA, and DNA binding are essential for CAF-1 functions in preventing DNA damage during DNA replication in Schizosaccharomyces pombe, while its C-terminal domain specifies distinct cellular processes.

    Activity of MukBEF for chromosome management in E. coli and its inhibition by MatP

    Mohammed Seba, Frederic Boccard, Stéphane Duigou
    MukBEF selectively loads onto newly replicated DNA, and MatP prevents MukBEF activity, correlating with matS sites, likely due to MatP-mediated unloading.
