Figure 4. Shear stress-dependent downregulation of endothelin-1 (ET-1) peptide release.
The effect of shear stress on ET-1 protein expression was quantified as ET-1 peptide release into the cell culture medium (in percentage of internal control without shear stress). The ET-1 release of HUVEC is downregulated by long-term (24 h) shear stress in a dose-dependent manner. Values are given as means ±s.e.m.; n= 6; * P < 0.05 vs. static control (con) (static condition: open bar, shear stress: hatched bars).
