    Bim escapes displacement by BH3-mimetic anti-cancer drugs by double-bolt locking both Bcl-XL and Bcl-2

    Qian Liu et al.
    The pro-apoptotic BH3-protein Bim contains two distinct binding sites for anti-apoptotic proteins that together confer resistance of Bim/Bcl-2 and Bim/Bcl-XL complexes to BH3-mimetic drugs under development for use in humans.

    Cell type-specific transcriptomics of hypothalamic energy-sensing neuron responses to weight-loss

    Fredrick E Henry et al.
    Cell type-specific transcriptomics in energy homeostasis neurons has identified hundreds of genes and multiple signaling pathways that are regulated by weight loss in mice, as well as several previously unexamined genes that can regulate appetite and body weight.

    Quantitative and functional interrogation of parent-of-origin allelic expression biases in the brain

    Julio D Perez et al.
    A subset of genes in the mouse brain show dynamically regulated and unequal expression of maternally and paternally derived variants, with implications for brain development and function.

    Burst mitofusin activation reverses neuromuscular dysfunction in murine CMT2A

    Antonietta Franco et al.
    A trial of mitofusin activation shows neuron regeneration and phenotype reversal in vitro and in vivo in experimental Charcot–Marie–Tooth disease type 2A caused by mitofusin 2 mutations.

    Mechanism and preclinical prevention of increased breast cancer risk caused by pregnancy

    Svasti Haricharan et al.
    The transcription factor STAT5 mediates the increased breast cancer risk associated with a late age pregnancy, but intermittent anti-STAT5 treatment can lower this risk and thus prevent breast cancer.

    The CUL5 ubiquitin ligase complex mediates resistance to CDK9 and MCL1 inhibitors in lung cancer cells

    Shaheen Kabir et al.
    Targeting the CRL5 ubiquitin ligase complex in combination with CDK9 or MCL1 inhibition could combat innate and acquired resistance of cancer cells to MCL1-targeting therapeutics.

    Compensatory growth renders Tcf7l1a dispensable for eye formation despite its requirement in eye field specification

    Rodrigo M Young et al.
    Disruptions to eye field size have little impact on final eye size due to tissue compensatory mechanisms.

    Disordered clusters of Bak dimers rupture mitochondria during apoptosis

    Rachel T Uren et al.
    Dimers of Bak assemble into clusters without using a distinct protein-protein interface, which may explain the apparent difficulties in obtaining high resolution structures of the pore complex and in targeting dimer-dimer interactions to regulate apoptosis.

    MAPK signaling promotes axonal degeneration by speeding the turnover of the axonal maintenance factor NMNAT2

    Lauren J Walker et al.
    Genetic and biochemical analysis reveals that MAPK signaling promotes axon degeneration by modulating the turnover of axon-protective proteins.

    Computationally designed high specificity inhibitors delineate the roles of BCL2 family proteins in cancer

    Stephanie Berger et al.
    Six computationally designed and in vitro optimized protein inhibitors serve as molecular probes to reveal BCL2 profiles of different human cancers.
