The connections between vascular calcification and bone health

Area of Science:

• Gerontology
• Vascular Biology
• Bone Metabolism

Background:

• Vascular calcification and bone loss are common age-related conditions often linked to increased mortality.
• Previously underestimated, the association between vascular calcification and impaired bone metabolism is now recognized as biologically interconnected.

Discussion:

• Vascular calcification involves vascular smooth muscle cells adopting an osteoblast-like phenotype, influenced by mineral metabolism factors like phosphorus, calcium, and parathyroid hormone.
• Emerging evidence suggests Wnt pathway inhibitors, such as secreted frizzled proteins and Dickkopf related protein-1 (DKK-1), may mediate the link between vascular calcification and bone loss.

Key Insights:

• Vascular calcification may directly impact bone metabolism, indicating a true crosstalk between these tissues.
• The progression of vascular calcification and its impact on patient outcomes are critical areas for investigation.

Outlook:

• Controlling chronic kidney disease-mineral and bone disorder components, particularly serum phosphorus, is crucial for maintaining bone turnover and preventing vascular calcification.
• Targeting these pathways could offer new therapeutic strategies for age-associated vascular and bone disorders.
