Vascular smooth muscle cell senescence in atherosclerosis.
Markers of cell senescence have been identified in both the blood and vessel wall of patients with atherosclerosis. In particular, vascular smooth muscle cells (VSMCs) derived from human plaques show numerous features of senescence both in culture and in vivo. This review summarises the evidence for VSMC senescence in atherosclerosis, and outlines the mechanisms and triggers leading to their se...
متن کاملVascular smooth muscle cell in atherosclerosis.
Vascular smooth muscle cells (VSMCs) exhibit phenotypic and functional plasticity in order to respond to vascular injury. In case of the vessel damage, VSMCs are able to switch from the quiescent 'contractile' phenotype to the 'proinflammatory' phenotype. This change is accompanied by decrease in expression of smooth muscle (SM)-specific markers responsible for SM contraction and production of ...
متن کاملRas induces vascular smooth muscle cell senescence and inflammation in human atherosclerosis.
BACKGROUND Vascular cells have a finite cell lifespan and eventually enter an irreversible growth arrest, cellular senescence. The functional changes associated with cellular senescence are thought to contribute to human aging and age-related vascular disorders. Ras, an important signaling molecule involved in atherogenic stimuli, is known to promote aging in yeast and cellular senescence in pr...
متن کاملVascular Smooth Muscle Cell Senescence Promotes Atherosclerosis and Features of Plaque Vulnerability.
BACKGROUND Although vascular smooth muscle cell (VSMC) proliferation is implicated in atherogenesis, VSMCs in advanced plaques and cultured from plaques show evidence of VSMC senescence and DNA damage. In particular, plaque VSMCs show shortening of telomeres, which can directly induce senescence. Senescence can have multiple effects on plaque development and morphology; however, the consequence...

Circulation Research is available at http://circres.ahajournals.org DOI: 10.1161/CIRCRESAHA.115.306361 Abstract: The historical view of vascular smooth muscle cells (VSMCs) in atherosclerosis is that aberrant proliferation of VSMCs promotes plaque formation, but that VSMCs in advanced plaques are entirely beneficial, for example preventing rupture of the fibrous cap. However, this view has been...
