    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.

    Embryonic transcription factor expression in mice predicts medial amygdala neuronal identity and sex-specific responses to innate behavioral cues

    Julieta E Lischinsky et al.
    Studying the development of the medial amygdala in the mouse reveals how the brain may potentially process sex differences in innate behaviors such as mating.

    TP53 drives invasion through expression of its Δ133p53β variant

    Gilles Gadea et al.
    Clinical analysis corroborated with experimental data demonstrate that Δ133p53β, a naturally occurring isoform of p53 protein, induces a pro-metastatic program and is a clinical indicator of metastasis, independently of TP53 mutation status.

    Asymmetric division triggers cell-specific gene expression through coupled capture and stabilization of a phosphatase

    Niels Bradshaw, Richard Losick
    Asymmetric cell division is linked to cell-specific transcription by handoff of a key developmental regulator from the cytokinetic machinery to the adjacent cell pole where it oligomerizes to become stabilized and activated.

    Ribosomal mutations promote the evolution of antibiotic resistance in a multidrug environment

    James E Gomez et al.
    Mutations in several components of a bacterial ribosome are shown to broadly decrease antibiotic and stress sensitivity, and readily accessible reversion mutations allow these ribosomal mutations to serve as stepping stones to high level antibiotic resistance.

    RNA Polymerase II cluster dynamics predict mRNA output in living cells

    Won-Ki Cho et al.
    Quantitative super resolution imaging, in live mammalian cells, reveals a direct relationship between protein clustering dynamics and the number of mRNA transcribed at an endogenous gene locus.

    An extensive program of periodic alternative splicing linked to cell cycle progression

    Daniel Dominguez et al.
    Extensive periodic regulation of alternative splicing during the cell cycle in genes is linked to cell cycle functions, and involves an auto-inhibitory mechanism that uses the protein kinase CLK1.

    Determination of ubiquitin fitness landscapes under different chemical stresses in a classroom setting

    David Mavor et al.
    Chemical perturbation-dependent deep mutational scanning data collected by a lab-based interdisciplinary graduate class resolves a paradox between the high evolution conservation and the high mutational tolerance of the protein ubiquitin.

    CDK-regulated dimerization of M18BP1 on a Mis18 hexamer is necessary for CENP-A loading

    Dongqing Pan et al.
    The stoichiometry and mechanism of interactions of the Mis18 complex with M18BP1 was analysed to unveil the molecular basis of new CENP-A deposition during the G1 phase of the cell cycle.

    Loss of Frataxin induces iron toxicity, sphingolipid synthesis, and Pdk1/Mef2 activation, leading to neurodegeneration

    Kuchuan Chen et al.
    In Drosophila, the loss of Frataxin causes iron accumulation in the nervous system, which in turn enhances sphingolipid synthesis and activation of PDK1 and Mef2, which leads to neurodegeneration.
