  60. ncbi Pivotal role of Cu,Zn-superoxide dismutase in endothelium-dependent hyperpolarization
    Keiko Morikawa
    Department of Cardiovascular Medicine, Kyushu University Graduate School of Medical Sciences, Fukuoka 812 8582, Japan
    J Clin Invest 112:1871-9. 2003
    ..These results prove the novel concept that endothelial Cu,Zn-SOD plays an important role as an "EDHF synthase" in mice, in addition to its classical role to scavenge superoxide anions...
  61. ncbi Interleukin-1beta induces death in chondrocyte-like ATDC5 cells through mitochondrial dysfunction and energy depletion in a reactive nitrogen and oxygen species-dependent manner
    Rika Yasuhara
    Department of Biochemistry, Showa University School of Dentistry, Tokyo 142 8555, Japan
    Biochem J 389:315-23. 2005
    ..These results suggest that the death of chondrocyte-like ATDC5 cells was mediated at least in part by mitochondrial dysfunction and energy depletion through ONOO- formation after IL-1beta treatment...
  62. ncbi Phosphoinositide 3-kinase in nitric oxide synthesis in macrophage: critical dimerization of inducible nitric-oxide synthase
    Kouhei Sakai
    Department of Microbiology and Immunology, Yamaguchi University School of Medicine, 1 1 1 Minami kogushi, Ube shi, Yamaguchi ken 755 8505, Japan
    J Biol Chem 281:17736-42. 2006
    ..Our current results demonstrate a critical role of class IA type PI3K in the bactericidal activity of macrophages by regulating their NO production through GTP cyclohydrolase 1 induction...
  63. ncbi Nitric oxide regulation of MMP-9 activation and its relationship to modifications of the cysteine switch
    Sean M McCarthy
    Department of Pathology, University of Vermont, Burlington, Vermont 05405, USA
    Biochemistry 47:5832-40. 2008
    ..Collectively, our results demonstrate that NO is incapable of directly activating proMMP-9 and that S-nitrosylation of MMP-9 propeptide by NO-donors is unrelated to their ability to regulate MMP-9 activity...
