Regulation of Foxo‐1 and the angiopoietin‐2/Tie2 system by shear stress
Abstrak
Transcription factor Foxo‐1 can be inactivated via Akt‐mediated phosphorylation. Since shear stress activates Akt, we determined whether Foxo‐1 and the Foxo‐1‐dependent, angiogenesis‐related Ang‐2/Tie2‐system are influenced by shear stress in endothelial cells. Expression of Foxo‐1 and its target genes p27Kip1 and Ang‐2 was decreased under shear stress (6 dyn/cm2, 24 h), nuclear exclusion of Foxo‐1 by phosphorylation increased. eNOS and Tie2 were upregulated. No effects on Ang‐1 expression were detected. In conclusion, Foxo‐1 and Ang‐2/Tie2 are part of the molecular response to shear stress, which may regulate angiogenesis.
