We recently reported that prolonged exposure of human aortic endothelial cells ( HAEC ) to low shear stress flow patterns is associated with a sustained increase in the activated form of the transcriptional regulator nuclear factor-kappaB ( NF-kappaB ).
 ( protein: NF-kappaB, None) , ( protein: nuclear factor-kappaB, None) , ( cell line: HAEC, None) , ( cell type: human aortic endothelial cells, None)
