lncRNAs in vascular senescence and microvascular remodeling

Long noncoding RNAs (lncRNAs) have emerged as critical regulators of vascular senescence and microvascular remodeling, processes that significantly contribute to the development of age-related diseases in organs such as the kidneys, heart, and lungs. Through mechanisms like chromatin remodeling, transcriptional regulation, and posttranscriptional modifications, lncRNAs modulate gene expression, thereby influencing cellular processes such as apoptosis, inflammation, fibrosis, and angiogenesis. In chronic kidney disease, cardiovascular disease, and pulmonary disorders, lncRNAs play a central role in promoting vascular dysfunction, endothelial cell aging, and fibrosis. This review focuses on how lncRNAs contribute to endothelial dysfunction, fibrosis, and vascular aging, emphasizing their roles in disease progression within the kidneys, heart, and lungs, where lncRNA-mediated vascular changes play a significant role in disease progression. Understanding the interactions between lncRNAs, vascular senescence, and microvascular remodeling offers promising avenues for developing targeted therapeutic strategies to mitigate the impact of aging on vascular health.
