    Human genetic analyses of organelles highlight the nucleus in age-related trait heritability

    Rahul Gupta et al.
    Although cellular organelles show a functional deterioration in aging, genetic loci associated with common age-associated disease instead nominate nuclear transcription factors across several age-related diseases.

    Inducible and reversible inhibition of miRNA-mediated gene repression in vivo

    Gaspare La Rocca et al.
    A new genetically engineered mouse strain is described in which miRNA activity can be acutely and reversibly inhibited, showing that in a subset of adult tissues miRNA activity is dispensable under homeostatic conditions but becomes essential during tissue regeneration.

    Adult stem cell-derived complete lung organoid models emulate lung disease in COVID-19

    Courtney Tindle et al.
    An integrated stem cell-based disease modeling and computational approach demonstrates how proximal airway epithelium is critical for SARS-CoV-2 infectivity and distal alveolar cells are critical for simulating the host responses.

    YAP and TAZ are transcriptional co-activators of AP-1 proteins and STAT3 during breast cellular transformation

    Lizhi He et al.
    YAP and TAZ, the ultimate targets of the Hippo signaling pathway, are transcriptional co-activators of AP-1 proteins and STAT3 through which they are important for breast cellular transformation.

    The dual role of amyloid-β-sheet sequences in the cell surface properties of FLO11-encoded flocculins in Saccharomyces cerevisiae

    Clara Bouyx et al.
    The role of amyloid-β-aggregation sequence and of the various domains in the physiological function of the FLO11-encoded adhesin in the yeast Saccharomyces cerevisiae are disclosed in this report.

    A prion accelerates proliferation at the expense of lifespan

    David M Garcia et al.
    In its capacity to switch into a heritable, prionogenic form, a conserved RNA-modifying enzyme epigenetically alters fundamental growth, aging, and protein synthesis properties of eukaryotic cells.

    Vaccination induces rapid protection against bacterial pneumonia via training alveolar macrophage in mice

    Hao Gu et al.
    Intranasal immunization of inactivated whole cell of some Gram-negative bacteria induces very rapid and efficient protection against bacterial pulmonary by training alveolar macrophage response, which can be harnessed to design rapid-effecting vaccine against multidrug-resistant bacteria infection.

    Aorta smooth muscle-on-a-chip reveals impaired mitochondrial dynamics as a therapeutic target for aortic aneurysm in bicuspid aortic valve disease

    Mieradilijiang Abudupataer et al.
    An aorta smooth muscle-on-a-chip model indicated that NOTCH1 insufficiency in HAoSMCs induced phenotypic switching from a contractile to a synthetic phenotype accompanied by an impairment of mitochondrial fusion, implying its potential role as a therapeutic target for BAV-TAA.

    A population-level invasion by transposable elements triggers genome expansion in a fungal pathogen

    Ursula Oggenfuss et al.
    The activation of transposable elements and relaxed purifying selection underpin an incipient expansion of the genome in populations of a major wheat pathogen.

    Leveraging the Mendelian disorders of the epigenetic machinery to systematically map functional epigenetic variation

    Teresa Romeo Luperchio et al.
    Chromatin/transcriptome profiling in multiple mouse models with mutations in epigenetic machinery (EM) reveals shared abnormalities including many IgA-relevant genes, indicating that this kind of joint analysis may elucidate the multigenic nature of EM disorders.
