    Using single-cell DNA sequencing after an error-prone mitosis in untransformed, diploid cell lines and organoids, chromosomes are shown to have different segregation error frequencies that result in non-random aneuploidy landscapes.

    Telomeric-repeat-containing RNA is recruited to telomeres by a mechanism that involves the DNA recombinase RAD51 and the formation of DNA–RNA hybrids, or R-loops—a process similar to that involved in homology-directed DNA repair.

    The surfactant-like protein Ki-67 mediates the clustering of chromosomes during mitotic exit, which displaces large cytoplasmic molecules from the future nuclear space and thus enables the separation of cytoplasmic and nuclear components before the nuclear envelope reforms.

  • Article |

    In a study performed in Schizosaccharomyces pombe, ‘closed mitosis’ is shown to occur via local disassembly of the nuclear envelope within the narrow bridge connecting segregating daughter nuclei, and a key role is identified for Les1, which restricts nuclear envelope breakdown to the bridge.

    The chromatin protein MeCP2 is a component of dynamic, liquid-like heterochromatin condensates, and the ability of MeCP2 to form condensates is disrupted by mutations in the MECP2 gene that occur in the neurodevelopmental disorder Rett syndrome.

    RNA polymerase II has an unexpected function in the nucleolus, helping to drive the expression of ribosomal RNA and to protect nucleolar structure through a mechanism involving triplex R-loop structures.

    The three-dimensional structure of pericentromeres in budding yeast is defined by convergent genes, which mark pericentromere borders and trap cohesin complexes loaded at centromeres, generating an architecture that allows correct chromosome segregation.

    Structural and microscopy studies of gene transcription underpin a model in which phosphorylation controls the shuttling of RNA polymerase II between promoter and gene-body condensates to regulate transcription initiation and elongation.

    A disease model using cardiomyocytes derived from induced pluripotent stem cells of patients with mutated LMNA-related dilated cardiomyopathy reveals that the abnormal activation of the PDGF pathway is associated with the arrhythmic phenotypes of patients.

    Spatial genome organization into lamina-associated domains is first established in the mouse zygote immediately after fertilization without inheritance from the maternal germline—with the paternal and maternal pronucleus exhibiting different organization, which subsequently converges prior to implantation of the embryo.

    Long-read sequencing allows the assembly of antigen-gene arrays in Trypanosoma brucei and, coupled with deletion experiments, demonstrates that histone variants act as a molecular link between genome architecture, chromatin conformation and antigen variation.

    HP1a can nucleate into foci that display liquid properties during the early stages of heterochromatin domain formation in Drosophila embryos, suggesting that the repressive action of heterochromatin may be mediated in part by emergent properties of phase separation.

    A candidate-based genetic screen in Drosophila expressing 30 G4C2-repeat-containing RNAs finds that RanGAP, a key regulator of nucleocytoplasmic transport, is a potent suppressor of neurodegeneration; the defects caused by the G4C2 repeat expansions can be rescued with antisense oligonucleotides or small molecules targeting the G-quadruplexes.

    The ESCRT-III complex is implicated in the reformation of the nuclear envelope; the CHMP2A component of ESCRT-III is directed to the forming nuclear envelope through classical ESCRT-assembly mechanisms, with the help of the p97 complex component UFD1, and provides an activity essential for nuclear envelope reformation.

    HIV-1 integration into the host cell genome occurs in the outer shell of the nucleus in close correspondence with the nuclear pore, in which a series of cellular genes are preferentially targeted by the virus.

    A protein degradation pathway is found at the inner nuclear membrane that is distinct from, but complementary to, endoplasmic-reticulum-associated protein degradation, and which is mediated by the Asi protein complex; a genome-wide library screening of yeast identifies more than 20 substrates of this pathway, which is shown to target mislocalized integral membrane proteins for degradation.
