Abstract EN
Vascular endothelial cells have an extensive response to physiological levels of shear stress.
There is evidence that the protein caveolin-1 is involved in the early phase of this response.
In this study, caveolin-1 was downregulated in human endothelial cells by RNAi.
When these cells were subjected to a shear stress of 15 dyn/cm2 for 10 minutes, activation of Akt and ERK1/2 was significantly lower than in control cells.
Moreover, activation of Akt and ERK1/2 in response to vascular endothelial growth factor was significantly lower in cells with low levels of caveolin-1.
However, activation of integrin-mediated signaling during cell adhesion onto fibronectin was not hampered by lowered caveolin-1 levels.
In conclusion, caveolin-1 is an essential component in the response of endothelial cells to shear stress.
Furthermore, the results suggest that the role of caveolin-1 in this process lies in facilitating efficient VEGFR2-mediated signaling.
