The advancement of medical technology has led not only to an increase in life expectancy but also to a rise in aging-related diseases. Aging promotes metabolic disorders, in turn affecting cardiovascular health. Derailment of biological processes in the pancreas, liver, adipose tissue, and skeletal muscle impairs glucose and lipid metabolism, and mitochondrial function, triggering the development of diabetes and lipid-related disorders that inflict damage on cardiac and vascular tissues. Long noncoding RNAs (lncRNAs) regulate a wide range of biological process and are one of the key factors controlling metabolism and mitochondria. Here, we discuss the versatile function of lncRNAs involved in the metabolic regulation of glucose and lipid, and mitochondrial function, and how the dysregulation of lncRNAs induces the development of various metabolic disorders and their cardiovascular consequences.
Cardiovascular diseases are the most prominent cause of death in Western society, especially in the elderly. With the increasing life expectancy, the number of patients with cardiovascular diseases will rise in the near future, leading to an increased healthcare burden. There is a need for new therapies to treat this growing number of patients. The discovery of long non-coding RNAs has led to a novel group of molecules that could be considered for their potential as therapeutic targets. This review presents an overview of long non-coding RNAs that are regulated in vascular disease and aging and which might therefore give insight into new pathways that could be targeted to diagnose, prevent, and/or treat vascular diseases.
Atherosclerosis and its sequelae, such as myocardial infarction and stroke, are the leading cause of death worldwide. Vascular endothelial cells (EC) play a critical role in vascular homeostasis and disease. Atherosclerosis as well as its independent risk factors including diabetes, obesity, and aging, are hallmarked by endothelial activation and dysfunction. Metabolic pathways have emerged as key regulators of many EC functions, including angiogenesis, inflammation, and barrier function, processes which are deregulated during atherogenesis. In this review, we highlight the role of glucose, fatty acid, and amino acid metabolism in EC functions during physiological and pathological states, specifically atherosclerosis, diabetes, obesity and aging.
