In addition, HEK-Trx2 are more sensitive toward rotenone, an inhibitor of complex I of the respiratory chain.

Auranofin was also able to unmask the production of hydrogen peroxide occurring in the presence of rotenone.
As the mitochondrial metabolism of hydrogen peroxide proceeds through the peroxidases linked to glutathione or thioredoxin, the relative efficiency of the two systems and the effects of auranofin were tested.

16449798 Hsieh CC, Papaconstantinou J: Thioredoxin-ASK1 complex levels regulate ROS-mediated p38 MAPK pathway activity in livers of aged and long-lived Snell dwarf mice. FASEB J. 2006 Feb;20(2):259-68.

Here we propose that activation of the p38 MAPK pathway by complex I (CI) generated ROS, in response to rotenone (ROT) treatment, is based on the ability of reduced Trx to bind to and inhibit ASK 1 and its release from the complex upon oxidation.

20157567 Hsieh CC, Papaconstantinou J: Dermal fibroblasts from long-lived Ames dwarf mice maintain their in vivo resistance to mitochondrial generated reactive oxygen species (ROS). Aging (Albany NY). 2009 Jul 31;1(9):784-802.

Activation of p38 MAPK by ROS involves dissociation of an inactive, reduced thioredoxin-ASK1 complex [(SH)(2) Trx-ASK1].
In these studies we demonstrate that dermal fibroblasts from these long-lived mice exhibit (a) higher levels of (SH)(2) Trx-ASK1 that correlate with their resistance to ROS generated by inhibitors of electron transport chain complexes CI (rotenone), CII (3-nitropropionic acid), CIII, (antimycin A), and H (2) O (2)-mediated activation of p38 MAPK, and (b) maintain their in vivo resistance to ROS generated by 3NPA.
