Hydrogen sulfide mediates athero-protection against oxidative stress via S-sulfhydration.

ABSTRACT: S-sulfhydration is a signalling pathway of hydrogen sulfide (H2S), which is suggested as an anti-atherogenic molecule that may protect against atherosclerosis. The identification of S-sulfhydrated proteins by proteomic approach could be a major step towards understanding the mechanisms of H2S in response to atherosclerosis. The present study studied targeted S-sulfhydrated proteins using the modified biotin switch method followed by matrix-assisted laser desorption/ionisation time of flight tandem mass spectrometry identification. The results showed that H2S can protect against atherosclerosis by reducing body weight gain and alleviating aortic plaque formation. In addition, H2S treatment can increase aortic protein S-sulfhydration. Seventy targeted S-sulfhydrated aortic proteins were iden
