Conclusions In this presentation, it was highlighted:
the emerging and rapidly expanding role of redox regulation during EGFR signaling (ii) the unique chemistry of reactive cysteine residues within specific target proteins, including EGFR (iii) the co-localization of the oxidant sources with the redox-regulated target protein the value of selective and cell-permeable chemical approaches to elucidating regulatory mechanisms that govern H2O2-mediated sulfenylation of proteins Given that aberrant sulfenylation of proteins is linked to aggressive cancer phenotypes, these discoveries may form the basis for the development of new therapeutic anti-cancer strategies
