Targeting Telomere Shortening in Vascular Aging and Atherosclerosis: Therapeutic Promise of Astragalus membranaceus

By Canale P, Andreassi MG

Telomere dysfunction has emerged as a pivotal contributor to vascular senescence, a fundamental process in the pathogenesis of age-related cardiovascular diseases such as atherosclerosis. This connection underscores the therapeutic potential of targeting telomere biology to prevent or mitigate the progression of vascular aging. In this context, Astragalus membranaceus and its bioactive constituents, including astragaloside IV, cycloastragenol, and the commercial telomerase activator TA-65, demonstrate significant promise in attenuating vascular aging and atherosclerotic disease. These compounds exert a range of pleiotropic effects, including anti-inflammatory, antioxidant, endothelial-protective, and lipid-modulating actions, while also modulating telomerase activity and supporting telomere maintenance. This review provides an overview of the mechanistic basis underlying the anti-atherosclerotic effects of Astragalus-derived compounds and underscores critical key knowledge gaps. It also outlines future research directions necessary to validate their efficacy and therapeutic potential in the prevention and treatment of atherosclerosis and other age-related vascular disorders.
