    Arid1b haploinsufficient mice reveal neuropsychiatric phenotypes and reversible causes of growth impairment

    Cemre Celen et al.
    Mirroring human patients with ARID1B mutations, Arid1b haploinsufficient mice exhibited numerous neuropsychiatric defects and revealed IGF1 deficiency related growth impairment that could be ameliorated with growth hormone supplementation.

    Environment determines evolutionary trajectory in a constrained phenotypic space

    David T Fraebel et al.
    Experimental evolution shows that when selection acts on two traits constrained by a trade-off, the direction of phenotypic evolution depends on the environment.

    MELK expression correlates with tumor mitotic activity but is not required for cancer growth

    Christopher J Giuliano et al.
    Cancer cells can grow in vitro and in vivo in the absence of maternal embryonic leucine zipper kinase (MELK).

    Transient external force induces phenotypic reversion of malignant epithelial structures via nitric oxide signaling

    Benjamin L Ricca et al.
    In a 3D culture model of breast epithelium, application of a short-timescale compression to single malignant cells promotes the long-timescale development of polarized, growth-arrested structures.

    Mice deficient of Myc super-enhancer region reveal differential control mechanism between normal and pathological growth

    Kashyap Dave et al.
    A tumor-specific regulatory region has been identified upstream of the Myc oncogene.

    Proteotoxicity from aberrant ribosome biogenesis compromises cell fitness

    Blake W Tye et al.
    Rapidly proliferating cells are at risk of compromised cell fitness due to proteostasis collapse from perturbations that interfere with ribosome biogenesis.

    Fitness effects of altering gene expression noise in Saccharomyces cerevisiae

    Fabien Duveau et al.
    The impact of changing gene expression noise on fitness reveals beneficial or deleterious effects in a stable environment depending how close the average expression level is to the fitness optimum.
