New long noncoding RNA drives vascular aging through energy metabolism decline

Research in Cardiovascular Research identifies a previously unknown molecular driver of vascular aging. The long noncoding RNA dubbed LncAAT becomes more active with age and promotes endothelial cell senescence—the dysfunctional state that contributes to atherosclerosis, hypertension, and cardiovascular disease. Crucially, the study demonstrates that LncAAT works by suppressing cellular energy metabolism, revealing a direct mechanistic link between metabolic decline and vascular aging. This matters because vascular aging is arguably the most important contributor to human healthspan decline, underlying heart disease, stroke, kidney disease, and even cognitive impairment. Long noncoding RNAs are emerging as master regulators of aging processes, and they may be more druggable than previously thought. The identification of LncAAT provides a specific target for interventions aimed at preserving vascular health. If the mechanism holds in humans, therapies that reduce LncAAT activity or restore the downstream metabolic pathways could potentially slow vascular aging and reduce cardiovascular disease burden—one of the most promising applications for translational longevity science.
