Key result
Inflammation and hypertension upregulate endothelial BMP-2 expression via H2O2-mediated NF-kappaBeta activation.
Why the study?
The factors that regulate arterial expression of bone morphogenetic protein-2 (BMP-2) in endothelial cells are completely unknown despite its role in vascular development and coronary atherosclerosis.
Population
Primary coronary arterial endothelial cells, human umbilical vein endothelial cells, rat arteries, and vessels of TNF-alpha knockout mice
Comparison
Proinflammatory and mechanical stimuli versus control conditions
Design
Experimental study using cell cultures and organ culture models

May link inflammation/hypertension to endothelial BMP-2 via H₂O₂/NF-κB; hypothesis-generating for atherosclerosis mechanisms.
Vascular BMP-2 expression is regulated by H2O2-mediated activation of NF-kappaBeta in response to inflammatory stimuli and high intravascular pressure, suggesting a mechanism for endothelial activation in atherosclerosis.
Csiszár et al. (2005) studied this question. Proinflammatory stimuli (TNF-alpha) and high intravascular pressure was evaluated on BMP-2 expression. Proinflammatory stimuli and high intravascular pressure upregulated vascular BMP-2 expression via an H2O2-mediated activation of NF-kappaBeta in endothelial cells.
