Oxidative stress has almost universally and unequivocally been implicated in the pathogenesis of all major diseases, including those of the cardiovascular system. Oxidative stress in cells and cardiovascular biology was once considered only in terms of injury, disease and dysfunction. However, it is now appreciated that oxidants are also produced in healthy tissues, and they function as signalling molecules transmitting information throughout the cell. Conversely, when cells move to a more reduced state, as can occur when oxygen is limiting, this can also result in alterations in the function of biomolecules and subsequently cells. At the centre of this 'redox signalling' are oxidoreductive chemical reactions involving oxidants or reductants post translationally modifying proteins. These structural alterations allow changes in cellular redox state to be coupled to alterations in cell function. In this review, we consider aspects of redox signalling in the cardiovascular system, focusing on the molecular basis of redox sensing by proteins and the array of post-translational oxidative modifications that can occur. In addition, we discuss studies utilising proteomic methods to identify redox-sensitive cardiac proteins, as well as those using this technology more broadly to assess redox signalling in cardiovascular disease
