The Link between miRNAs and PCKS9 in Atherosclerosis

Area of Science:

• Cardiovascular Science
• Molecular Biology
• Immunology

Background:

• Cardiovascular disease (CVD) is a leading global cause of mortality, with atherosclerosis as its primary driver.
• Atherosclerosis is a complex inflammatory condition involving lipid accumulation, foam cell formation, and plaque development.
• Dysregulation of cholesterol metabolism in macrophages, particularly foam cell formation, is central to atherosclerotic pathophysiology.

Purpose of the Study:

• To review the role of proprotein convertase subtilisin/kexin type 9 (PCSK9) in atherosclerosis.
• To examine the involvement of microRNAs (miRNAs) in regulating PCSK9-related genes and lipid metabolism.
• To discuss PCSK9 pathway-targeting and miRNA-based therapeutic interventions for atherosclerosis.

Main Methods:

• Literature review of recent findings on PCSK9, miRNAs, and atherosclerosis.
• Analysis of the molecular mechanisms linking PCSK9, miRNAs, and lipid metabolism.
• Synthesis of information on current and emerging therapeutic strategies.

Main Results:

• PCSK9 significantly regulates low-density lipoprotein receptor (LDLR) degradation, impacting circulating LDL cholesterol levels and contributing to atherosclerosis.
• miRNAs are identified as key epigenetic regulators involved in the pathophysiology of atherosclerosis and lipid metabolism.
• The interplay between PCSK9 and miRNAs presents novel therapeutic targets for managing atherosclerosis.

Conclusions:

• Targeting the PCSK9 pathway and modulating miRNA levels offer promising therapeutic avenues for atherosclerosis.
• Understanding the intricate relationship between PCSK9, miRNAs, and foam cell formation is crucial for developing effective CVD treatments.
• Further research into PCSK9 inhibition and miRNA-based therapies could lead to significant advancements in cardiovascular disease management.
