PMID:18497292 purification of TXN and TXNRD as a NADPH-dependent caspase-3 SNO reductase system in 10C9 human B lymphocytes, siRNA-mediated depletion of TXN or TXNRD1 increases the amount of S-nitroso-CASP3 identification of a mixed disulfide between CASP3 and TXN resolving cysteine mutant upon CysSNO suggests that TXN is oxidized to a disulfide during CASP3 denitrosation
