    Cytoplasmic translocation of the retinoblastoma protein disrupts sarcomeric organization

    Keigo Araki et al.
    TNF-α treatment induces phosphorylation and cytoplasmic translocation of the retinoblastoma protein, which regulates cytoskeletal organization in skeletal muscle cells.

    A new class of cyclin dependent kinase in Chlamydomonas is required for coupling cell size to cell division

    Yubing Li et al.
    CDKG1 is a D-cyclin dependent retinoblastoma related protein kinase whose abundance scales with cell size and controls cell division cycle number during multiple fission.

    Opposing roles for DNA replication initiator proteins ORC1 and CDC6 in control of Cyclin E gene transcription

    Manzar Hossain, Bruce Stillman
    Two related DNA replication initiation proteins contribute to the decision of whether to enter a new round of the cell division cycle or enter into a period of proliferative quiescence.

    Irreversible fate commitment in the Arabidopsis stomatal lineage requires a FAMA and RETINOBLASTOMA-RELATED module

    Juliana L Matos et al.
    An adult stem-cell lineage terminally differentiates via recruitment of the RETINOBLASTOMA-RELATED protein by a lineage specific transcription factor.

    The DREAM complex through its subunit Lin37 cooperates with Rb to initiate quiescence

    Christina FS Mages et al.
    Lin37 is essential for cell-cycle gene repression by the DREAM complex in cellular quiescence and a combined loss of Lin37 and Rb prevents cell-cycle exit in response to growth-limiting signals.

    p16 deficiency attenuates intervertebral disc degeneration by adjusting oxidative stress and nucleus pulposus cell cycle

    Hui Che et al.
    A novel IVDD mechanism that involves p16 is demonstrated and theoretical evidence is provided for effective methods to downregulate p16 and so reverse IVDD.

    Cyclin D activates the Rb tumor suppressor by mono-phosphorylation

    Anil M Narasimha et al.
    The retinoblastoma tumor suppressor regulates cell cycle progression when it's in 14 mono-phosphorylated isoforms.

    Genome-wide CRISPR screen identifies noncanonical NF-κB signaling as a regulator of density-dependent proliferation

    Maria Fomicheva, Ian G Macara
    TRAF3, a negative regulator of noncanonical NF-κB signaling, maintains epithelial cell quiescence at confluence, and its loss triggers upregulation of immunity genes and prevents entry into G0 at high cell density.

    KIT ligand protects against both light-induced and genetic photoreceptor degeneration

    Huirong Li et al.
    A combination of in vitro and in vivo experiments demonstrate a cell-autonomous role of the KIT ligand/KIT signaling pathway in protecting retinal photoreceptor cells from environmentally or genetically caused degeneration.
