1 In an endothelial cell line stably expressing human somatic ACE, ramiprilat increased COX-2 promoter activity, an effect not observed in ACE-deficient cells or cells expressing a nonphosphorylatable ACE mutant (S1270A). ramiprilat angiotensin I converting enzyme Homo sapiens
2 The ramiprilat-induced, ACE-dependent increase in COX-2 expression and promoter activity (both 1.5- to 2-fold greater than control) was prevented by the inhibition of JNK. ramiprilat angiotensin I converting enzyme Homo sapiens
3 Ramiprilat significantly enhanced the DNA binding activity of activator protein-1 in cells expressing ACE but not S1270A ACE. ramiprilat angiotensin I converting enzyme Homo sapiens
