Mechanistically, TRI-03 not only increases intracellular reactive oxygen species (ROS) levels by inhibiting TrxR1 activity but also decreases XIAP expression, leading to the activation of the caspase-9/caspase-3/GSDME axis and irreversible GSDME-mediated pyroptosis in melanoma cells. This evidence concerns the gene CASP3 and melanoma.
