Arterial Stiffness and the Canonical WNT/β-catenin Pathway

Area of Science:

• Cardiovascular Research
• Molecular Biology
• Pathophysiology

Background:

• Arterial stiffness (AS) is a significant predictor of cardiovascular morbidity and mortality, particularly in hypertensive patients.
• Key risk factors for AS include aging, hypertension, vascular calcification, inflammation, and diabetes mellitus.
• The WNT/β-catenin pathway plays a crucial role in various cellular processes and is implicated in the development of these risk factors.

Purpose of the Study:

• To review the role of the WNT/β-catenin pathway in the development of arterial stiffness.
• To explore the connection between WNT/β-catenin pathway deregulation and arterial stiffness markers.

Main Methods:

• Literature review focusing on studies investigating arterial stiffness and the WNT/β-catenin pathway.
• Analysis of existing research on risk factors for arterial stiffness and their molecular underpinnings.

Main Results:

• Arterial stiffness, measured by aortic pulse wave velocity (PWV), is elevated in conditions like peripheral artery disease.
• Increased PWV is associated with a higher risk of cardiovascular events.
• Deregulation of the WNT/β-catenin pathway, specifically the inactivation of its inhibitors DKK1 and sclerostin, is linked to arterial stiffness.

Conclusions:

• The WNT/β-catenin pathway is a key contributor to the development of arterial stiffness.
• Understanding this pathway's role offers potential therapeutic targets for managing cardiovascular risk associated with arterial stiffness.
