    Ordered dephosphorylation initiated by the selective proteolysis of cyclin B drives mitotic exit

    James Holder, Shabaz Mohammed, Francis A Barr
    Selective APC/C-mediated proteolysis of cyclin B drives progression through the metaphase-anaphase transition whilst wide-spread waves of dephosphorylation co-ordinate the subsequent events of mitotic exit.

    CTCF confers local nucleosome resiliency after DNA replication and during mitosis

    Nick Owens, Thaleia Papadopoulou ... Pablo Navarro
    In contrast to other transcription factors, CTCF and Esrrb rapidly regain binding after replication and remain bound to their targets during mitosis, preserving local nucleosome organization throughout the cell cycle.

    Mammalian cell growth dynamics in mitosis

    Teemu P Miettinen, Joon Ho Kang ... Scott R Manalis
    High-resolution single-cell mass accumulation and protein synthesis rate measurements are used to quantify the extent, dynamics and consequences of animal cell growth in mitosis and cytokinesis.

    Splicing factors Sf3A2 and Prp31 have direct roles in mitotic chromosome segregation

    Claudia Pellacani, Elisabetta Bucciarelli ... Maria Patrizia Somma
    Extensive cytological and biochemical analyses show that the conserved Sf3A2 and Prp31 splicing factors bind microtubules and the Ndc80 complex, playing direct mitotic functions in both Drosophila and human mitosis.

    Regulation of mRNA translation during mitosis

    Marvin E Tanenbaum, Noam Stern-Ginossar ... Ronald D Vale
    Ribosomal profiling reveals that translational repression is an important mechanism for cell cycle control and can complement protein degradation.

    Mitotic progression, arrest, exit or death relies on centromere structural integrity, rather than de novo transcription

    Marco Novais-Cruz, Maria Alba Abad ... Cristina Ferrás
    Direct live-cell imaging of human cells, combined with RNA-seq, qPCR and in vitro reconstitution essays, reveal that mitotic progression, arrest, exit or death is independent of de novo transcription.

    Proteomic analysis of cell cycle progression in asynchronous cultures, including mitotic subphases, using PRIMMUS

    Tony Ly, Arlene Whigham ... Angus I Lamond
    A detailed analysis of protein abundance and phosphorylation changes across mitotic subphases and interphase in asynchronously growing human cells has been enabled by combining FACS with quantitative MS-based proteomics.

    Cooperation among c-subunits of FoF1-ATP synthase in rotation-coupled proton translocation

    Noriyo Mitome, Shintaroh Kubo ... Shoji Takada
    Biochemical analysis on hetero-mutated c10 subunits ring and molecular dynamics simulations demonstrate the cooperation among c-subunits of FoF1-ATP synthase in rotation-coupled proton translocation.

    Mitotic chromosomes scale to nuclear-cytoplasmic ratio and cell size in Xenopus

    Coral Y Zhou, Bastiaan Dekker ... Rebecca Heald
    A combination of in vivo and in vitro approaches using Xenopus eggs and embryos reveals how dimensions of mitotic chromosomes scale with decreasing cell size and increasing nuclear-cytoplasmic ratio during early embryogenesis.

    Nuclei determine the spatial origin of mitotic waves

    Felix E Nolet, Alexandra Vandervelde ... Lendert Gelens
    Nuclei and spatial system dimensions control local concentrations of cell cycle regulators, determining the spatial origin of waves that coordinate​ DNA replication and, subsequently, cell division.
