Noncoding RNAs regulate NF-κB signaling to modulate blood vessel inflammation

Area of Science:

• Cardiovascular Biology
• Molecular Medicine
• Aging Research

Background:

• Cardiovascular diseases, including atherosclerosis, are major global health burdens.
• Atherosclerosis progression is linked to vascular inflammation and endothelial cell activation.
• The transcription factor NF-κB is central to endothelial inflammatory signaling, with enhanced activity during aging.

Purpose of the Study:

• To review the role of microRNAs in regulating vascular inflammation and NF-κB signaling.
• To explore the therapeutic potential of microRNA-based interventions for cardiovascular diseases.
• To discuss emerging roles of long noncoding RNAs and circulating microRNAs in vascular health.

Main Methods:

• Literature review of studies on microRNAs, NF-κB signaling, and vascular inflammation.
• Analysis of data from mouse models of vascular inflammation and atherosclerosis.
• Synthesis of current knowledge on noncoding RNA regulation in endothelial cells.

Main Results:

• Noncoding RNAs, especially microRNAs, significantly modulate the NF-κB signaling pathway in vascular inflammation.
• Dysregulation of these microRNAs is implicated in the pathogenesis of atherosclerosis.
• Aging exacerbates NF-κB activation, potentially mediated by altered noncoding RNA expression.

Conclusions:

• MicroRNAs are key regulators of vascular inflammation and NF-κB activity.
• Targeting microRNA pathways presents a promising therapeutic strategy for atherosclerosis and age-related cardiovascular disease.
• Further research into long noncoding RNAs and circulating microRNAs may reveal novel therapeutic avenues.
