“ BK (10 nM) increased VSMC proliferation by 30% (n=5); this proliferation was inhibited by the antioxidants N-acetylcysteine (20 mM) and alpha-lipoic acid (LA, 250 mM).”
“Preincubation of VSMCs with either N-acetyl-L-cysteine and/or alpha-lipoic acid significantly decreased bradykinin-induced cytosolic and nuclear phosphorylation of p42(mapk) and p44(mapk).”
“Additional experiments supported the hypothesis that n-acetylcysteine is an oxygen radical scavenger, since it reduced or prevented the free radical-dependent cerebral arteriolar dilation normally induced by the topical application of arachidonic acid or bradykinin.”
