    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.

    LIN37-DREAM prevents DNA end resection and homologous recombination at DNA double-strand breaks in quiescent cells

    Bo-Ruei Chen et al.
    The LIN37-DREAM complex has a critical role in regulating DNA double-strand break end processing and suppressing aberrant homology-directed repair in quiescent cells.

    A terminal selector prevents a Hox transcriptional switch to safeguard motor neuron identity throughout life

    Weidong Feng et al.
    A molecular mechanism that involves highly conserved transcription factors enables cholinergic motor neurons of the nematode Caenorhabditis elegans to become and remain functional.

    NirD curtails the stringent response by inhibiting RelA activity in Escherichia coli

    Loïc Léger et al.
    Genetic and biochemical approaches uncover a novel mode of regulation of the alarmone synthetase RelA through a functional and direct interaction with the small subunit of the nitrite reductase NirD.

    The Fml1-MHF complex suppresses inter-fork strand annealing in fission yeast

    Io Nam Wong et al.
    Genomic deletions formed from inter-fork strand annealing associated with a collapsed replication fork are suppressed by the FANCM-related DNA helicase Fml1 in conjunction with its partner proteins Mhf1 and Mhf2.

    Zeb1 controls neuron differentiation and germinal zone exit by a mesenchymal-epithelial-like transition

    Shalini Singh et al.
    Neuronal progenitor cells autonomously inhibit polarization via the transcription factor Zeb1.

    Dynamic filopodia are required for chemokine-dependent intracellular polarization during guided cell migration in vivo

    Dana Meyen et al.
    Functional analysis of filopodia by specific interference with their formation and distribution reveals a critical role in conferring intracellular polarity and in controlling the dynamic properties of chemokine-guided cell migration in vivo.

    Characterization of the mechanism by which the RB/E2F pathway controls expression of the cancer genomic DNA deaminase APOBEC3B

    Pieter A Roelofs et al.
    The antiviral and genomic DNA deaminase APOBEC3B is repressed in normal cells by PRC1.6/E2F6 and DREAM/E2F4 complexes and deregulation of this axis provides a unifying mechanism for overexpression in cancer.

    Lineage mapping identifies molecular and architectural similarities between the larval and adult Drosophila central nervous system

    Haluk Lacin, James W Truman
    Mapping individual neural stem cells to their corresponding embryonic and postembryonic progeny shows that these sets of neurons have profound molecular and anatomical similarities despite building different central nervous systems.
