Roles of High Mobility Group Box 1 in Cardiovascular Calcification
Insights
Cardiovascular calcification is an active process. High mobility group box 1 (HMGB1) protein plays a key role in its development, though mechanisms require further study.
Area of Science:
- Cardiovascular Biology
- Molecular Medicine
- Biochemistry
Background:
- Cardiovascular calcification, a risk factor for adverse events, is now understood as an active, regulated process, not merely degenerative.
- Pathogenesis involves osteochondrogenic differentiation, apoptosis, and extracellular vesicle release, yet mechanisms remain unclear.
- High mobility group box 1 (HMGB1), a nuclear protein, acts as a damage-associated molecular pattern (DAMP) and bone-active cytokine.
Purpose of the Study:
- To review current understanding of cardiovascular calcification mechanisms.
- To discuss the multifaceted roles of High mobility group box 1 (HMGB1) in cardiovascular calcification.
Main Methods:
- Literature review of recent studies on cardiovascular calcification.
- Analysis of High mobility group box 1 (HMGB1) involvement in calcification pathways.
Main Results:
- Cardiovascular calcification is an active biological process.
- High mobility group box 1 (HMGB1) is implicated in cardiovascular calcification.
- The precise mechanisms of HMGB1's role require further investigation.
Conclusions:
- Understanding the active mechanisms of cardiovascular calcification is crucial.
- High mobility group box 1 (HMGB1) emerges as a significant factor in cardiovascular calcification.
- Further research is needed to elucidate the specific pathways HMGB1 utilizes in promoting cardiovascular calcification.
Abstract:
Calcific disease of the cardiovascular system, including atherosclerotic calcification, medial calcification in diabetes and calcific aortic valve disease, is an important risk factor for many adverse cardiovascular events such as ischemic cardiac events and subsequent mortality. Although cardiovascular calcification has long been considered to be a passive degenerative occurrence, it is now recognized as an active and highly regulated process that involves osteochondrogenic differentiation, apoptosis and extracellular vesicle release. Nonetheless, despite numerous studies on the pathogenesis of cardiovascular calcification, the underlying mechanisms remain poorly understood. High mobility group box 1 (HMGB1), a nuclear protein bound to chromatin in almost all eukaryotic cells, acts as a damage-associated molecular pattern (DAMP) when released into the extracellular space upon cell activation, injury or death. Moreover, HMGB1 also functions as a bone-active cytokine participating in bone remodeling and ectopic calcification pathogenesis. However, studies on the roles of HMGB1 in promoting cardiovascular calcification are limited to date, and the mechanisms involved are still unclear. In this review, we summarize recent studies investigating the mechanism of cardiovascular calcification and discuss multiple roles of HMGB1 in its development.
