Insights
Vascular calcification shares molecular mechanisms with bone mineralization. Understanding these shared pathways is crucial for developing effective therapies that consider both vascular and skeletal health.
Area of Science:
- Cardiovascular Biology
- Skeletal Biology
- Biomolecular Regulation
Background:
- Vascular calcification was historically viewed as a passive degenerative process.
- Emerging evidence highlights its active regulation, mirroring skeletal bone mineralization.
- Key biomolecules and regulatory pathways are now known to overlap between vascular and skeletal systems.
Purpose of the Study:
- To review the key biomolecules driving vascular calcification.
- To explore the regulation of ectopic calcification by metabolic, hormonal, and inflammatory factors.
- To discuss the implications of shared regulatory mechanisms for therapeutic strategies.
Main Methods:
- Literature review focusing on biomolecular mechanisms of vascular calcification.
- Analysis of regulatory pathways involving metabolic, hormonal, and inflammatory stimuli.
- Examination of the interplay between vascular calcification and skeletal mineralization.
Main Results:
- Bone morphogenetic proteins are implicated in atherosclerotic lesion calcification.
- Shared biomolecules and regulatory mechanisms control both vascular and skeletal mineralization.
- Vessel wall calcification influences plaque stability and cardiac event risk.
Conclusions:
- Vascular calcification is a complex, actively regulated process.
- Therapeutic interventions targeting vascular calcification must consider potential impacts on skeletal health.
- A balanced approach considering both systems is essential for effective treatment development.
Abstract:
Vascular calcification, once considered a degenerative, end-stage, and inevitable condition, is now recognized as a complex process regulated in a manner similar to skeletal bone at the molecular and cellular levels. Since the initial discovery of bone morphogenetic protein in calcified human atherosclerotic lesions, decades of research have now led to the recognition that the regulatory mechanisms and the biomolecules that control cardiovascular calcification overlap with those controlling skeletal mineralization. In this review, we focus on key biomolecules driving the ectopic calcification in the circulation and their regulation by metabolic, hormonal, and inflammatory stimuli. Although calcium deposits in the vessel wall introduce rupture stress at their edges facing applied tensile stress, they simultaneously reduce rupture stress at the orthogonal edges, leaving the net risk of plaque rupture and consequent cardiac events depending on local material strength. A clinically important consequence of the shared mechanisms between the vascular and bone tissues is that therapeutic agents designed to inhibit vascular calcification may adversely affect skeletal mineralization and vice versa. Thus, it is essential to consider both systems when developing therapeutic strategies.

The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
