Heparanase, Endothelial Dysfunction, and Cardiovascular Risk: The Emerging Role of Vitamin D

Area of Science:

• Cardiovascular Science
• Endothelial Biology
• Molecular Medicine

Background:

• Endothelial dysfunction is a key factor in cardiovascular disease (CVD).
• The endothelial glycocalyx is crucial for vascular homeostasis, regulating permeability and signaling.
• Heparanase degrades the glycocalyx, contributing to CVD pathologies.

Purpose of the Study:

• To explore the potential role of vitamin D in preserving endothelial integrity.
• To investigate vitamin D's effect on heparanase and the endothelial glycocalyx.

Main Methods:

• Review of existing literature on vitamin D, heparanase, and endothelial function.
• Analysis of studies demonstrating vitamin D's effects in related cellular models (e.g., podocytes).

Main Results:

• Heparanase activity exacerbates glycocalyx degradation, linked to oxidative stress, hyperglycemia, and hypertension.
• Vitamin D shows potential in maintaining glycocalyx structure and suppressing heparanase expression.
• Evidence from podocyte studies suggests a protective mechanism for vitamin D.

Conclusions:

• Vitamin D may protect the vasculature by inhibiting heparanase-mediated glycocalyx degradation.
• This action could mitigate endothelial dysfunction and reduce cardiovascular risk.
• Further research is warranted to confirm therapeutic potential in CVD.
