1 trans-4,5-Dihydroxy-1,2-dithiane, the intramolecular disulfide form of dithiothreitol (DTTox) transcriptionally activates the stress-responsive genes gadd153(chop) and grp78. Disulfides heat shock protein family A (Hsp70) member 5 Sus scrofa
2 Furthermore, the ring-open intermolecular disulfide form of DTTox, 2-hydroxyethyl disulfide, was only a weak inducer of grp78 and gadd153 but was a strong inducer of hsp70 mRNA and a potent oxidant that lowered the NADPH/NADP+ ratio and depleted reduced glutathione (GSH). Disulfides heat shock protein family A (Hsp70) member 5 Sus scrofa
