  • Nucleolar integrity during interphase supports faithful Cdk1 activation and mitotic entry

    Hayashi Yuki , Fujimura Akiko , Kato Kazashi , Udagawa Rina , Hirota Toru , Kimura Keiji , 木村 圭志

    … In addition to effects on overall mitotic phenotypes, NOL11 depletion reduced ribosomal RNA (rRNA) levels and caused nucleolar disruption during interphase. … Notably, mitotic phenotypes found in NOL11-depleted cells were recapitulated when nucleolar disruption was induced by depletion of rRNA transcription factors or treatment with actinomycin D. …
