    Clavreul N, Bachschmid M, Hou X, Shi C, Idrizovic A, Ido Y, et al. S-glutathiolation of p21ras by peroxynitrite mediates endothelial insulin resistance caused by oxidized low-density lipoprotein. Arterioscler Thromb Vasc Biol. 2006;26:2454-61 pubmed
    ..This study provides direct evidence for a novel molecular mechanism by which oxidants can induce insulin resistance via S-glutathiolation of p21ras and Erk-dependent inhibition of insulin signaling. ..
  3. Mei Y, Thompson M, Shiraishi Y, Cohen R, Tong X. Sarcoplasmic/endoplasmic reticulum Ca2+ ATPase C674 promotes ischemia- and hypoxia-induced angiogenesis via coordinated endothelial cell and macrophage function. J Mol Cell Cardiol. 2014;76:275-82 pubmed publisher
    ..This study highlights the hitherto unrecognized interaction of two ER proteins, SERCA 2 C674 and ERO1, which mediate the EC and macrophage angiogenic response to ischemia/hypoxia. ..
  4. Evangelista A, Thompson M, Bolotina V, Tong X, Cohen R. Nox4- and Nox2-dependent oxidant production is required for VEGF-induced SERCA cysteine-674 S-glutathiolation and endothelial cell migration. Free Radic Biol Med. 2012;53:2327-34 pubmed publisher
    ..These results demonstrate that VEGF stimulates EC migration through increased S-glutathiolation of SERCA and Ca(2+) influx in a Nox4- and H2O2-dependent manner, requiring Nox2 downstream. ..
