Scholarcy highlights

  • Thioredoxin 1 is a known redox regulator that is implicated in the redox control of cell growth and apoptosis inhibition
  • We show that Trx is essential for maintaining the content of S-nitrosylated molecules in endothelial cells
  • Trx itself is S-nitrosylated at cysteine 69 under basal conditions, and this S-nitrosylation is required for scavenging reactive oxygen species and for preserving the redox regulatory activity of Trx
