    Weight loss, insulin resistance, and study design confound results in a meta-analysis of animal models of fatty liver

    Harriet Hunter, Dana de Gracia Hahn ... Jake P Mann
    Animal studies of fatty liver disease over-estimate the benefit of drugs due to publication bias and are confounded by off-target weight loss, illustrating the challenge of successful translational across species.

    Early prediction of level-of-care requirements in patients with COVID-19

    Boran Hao, Shahabeddin Sotudian ... Ioannis Ch Paschalidis
    Using data for 2566 COVID-19 patients from five hospitals, models are developed to predict for each patient hospitalization and critical care needs, based on demographics, comorbidities, medications, and laboratory findings.

    Postnatal mechanical loading drives adaptation of tissues primarily through modulation of the non-collagenous matrix

    Danae E Zamboulis, Chavaunne T Thorpe ... Peter D Clegg
    Phase-specific mechanical and proteomic analyses reveal how tendon responds to its mechanical environment during postnatal development to meet functional requirements.

    Effects of lifelong testosterone exposure on health and disease using Mendelian randomization

    Pedrum Mohammadi-Shemirani, Michael Chong ... Guillaume Paré
    Long-term increased testosterone improved body composition and bone density, but lowered HDL and raised risks of hypertension, androgenic alopecia, prostate cancer, and spinal stenosis in males.

    APOE2 is associated with longevity independent of Alzheimer’s disease

    Mitsuru Shinohara, Takahisa Kanekiyo ... Guojun Bu
    Translational evidence indicates APOE2 benefits longevity independent of its protective effects on Alzheimer’s disease, which preserved activity and the metabolism of apoE protein and associated-lipids would be key to understanding.

    Patient-specific genomics and cross-species functional analysis implicate LRP2 in hypoplastic left heart syndrome

    Jeanne L Theis, Georg Vogler ... Rolf Bodmer
    Hypoplastic left heart syndrome is reflected by reduced proliferative capacity of patient iPSC-derived cardiomyocytes and requires the activity of LRP2/APOB proteins, likely in conjunction with SHH and WNT signaling pathways.

    Parkinson’s Disease: Debunking an old theory

    Teresa Spix, Aryn Gittis
    Recording the neural activity of cells in the brain of patients with Parkinson's disease challenges long-standing assumptions about how this disease manifests at the cellular level.

    PTPRG is an ischemia risk locus essential for HCO3-dependent regulation of endothelial function and tissue perfusion

    Kristoffer B Hansen, Christian Staehr ... Ebbe Boedtkjer
    HCO3-sensitive regulation of endothelium-dependent vasorelaxation by receptor-type tyrosine-protein phosphatase RPTPγ provides a novel mechanism for acid-base-mediated coordination of cerebrovascular perfusion during increased local metabolism and for protection against ischemia.

    Lack of airway submucosal glands impairs respiratory host defenses

    Lynda S Ostedgaard, Margaret P Price ... Michael J Welsh
    Submucosal glands are critical for two key respiratory host defenses, bactericidal activity and mucociliary transport, in an animal model that has lungs like humans.
