Abstract
Plasminogen activator inhibitor-1 (PAI-1) is a key driver of aging and contributes to diverse pathologies. This review examines PAI-1's multifaceted contributions to aging. At the cellular level, PAI-1 amplifies senescence, exhausts stem cell niches, and disrupts metabolism. These cellular alterations translate into physiological decline: PAI-1 drives cardiovascular aging by promoting vascular senescence and arterial stiffening, contributes to cognitive decline by impairing amyloid-beta clearance, fuels cancer progression through angiogenesis and immune suppression, and exacerbates muscle atrophy by hindering regeneration. A rare loss-of-function SERPINE1 mutation extends lifespan, illustrating how lifelong PAI-1 reduction can positively impact the human healthspan. Looking forward, targeting PAI-1 with inhibitors could mitigate senescence, restore stem cell function, improve metabolic profile, enhance physiological health, and promise a longer healthspan.
期刊介绍：
Biomedical Journal publishes 6 peer-reviewed issues per year in all fields of clinical and biomedical sciences for an internationally diverse authorship. Unlike most open access journals, which are free to readers but not authors, Biomedical Journal does not charge for subscription, submission, processing or publication of manuscripts, nor for color reproduction of photographs.
Clinical studies, accounts of clinical trials, biomarker studies, and characterization of human pathogens are within the scope of the journal, as well as basic studies in model species such as Escherichia coli, Caenorhabditis elegans, Drosophila melanogaster, and Mus musculus revealing the function of molecules, cells, and tissues relevant for human health. However, articles on other species can be published if they contribute to our understanding of basic mechanisms of biology.
A highly-cited international editorial board assures timely publication of manuscripts. Reviews on recent progress in biomedical sciences are commissioned by the editors.
