Nuclear Factor-kappaB-Mediated Endothelin Receptor Up-Regulation Increases Renal Artery Contractility in Rats
Increased renal artery contractility leads to renal vasospasm and ischaemia as well as kidney damage. This study was designed to examine the hypothesis that organ culture of renal arteries induces transcriptional up-regulation of endothelin type A (ETA) and type B2 (ETB2) receptors in the smooth muscle cells via activation of nuclear factor-kappaB (NF-B) and subsequently increases renal artery con
