Background.
The disruption of physiologic vascular smooth muscle cell (VSMC) migration initiates atherosclerosis development.
The biochemical mechanisms leading to dysfunctional VSMC motility remain unknown.
Recently, cytokine BMP-2 has been implicated in various vascular physiologic and pathologic processes.
However, whether BMP-2 has any effect upon VSMC motility, or by what manner, has never been investigated.
Methods.
VSMCs were adenovirally transfected to genetically overexpress BMP-2.
VSMC motility was detected by modified Boyden chamber assay, confocal time-lapse video assay, and a colony wounding assay.
Gene chip array and RT-PCR were employed to identify genes potentially regulated by BMP-2.
Western blot and real-time PCR detected the expression of myosin Va and the phosphorylation of extracellular signal-regulated kinases 1/2 (Erk1/2).
Immunofluorescence analysis revealed myosin Va expression locale.
Intracellular Ca2+ oscillations were recorded.
Results.
VSMC migration was augmented in VSMCs overexpressing BMP-2 in a dose-dependent manner.
siRNA-mediated knockdown of myosin Va inhibited VSMC motility.
Both myosin Va mRNA and protein expression significantly increased after BMP-2 administration and were inhibited by Erk1/2 inhibitor U0126.
BMP-2 induced Ca2+ oscillations, generated largely by a “cytosolic oscillator”.
Conclusion.
BMP-2 significantly increased VSMCs migration and myosin Va expression, via the Erk signaling pathway and intracellular Ca2+ oscillations.
We provide additional insight into the pathophysiology of atherosclerosis, and inhibition of BMP-2-induced myosin Va expression may represent a potential therapeutic strategy.
