title: Cytochrome c reduction by triiodothyronine (T3).
abstract: Triiodothyronine (T3), the active thyroid hormone, reduced cytochrome c non-enzymatically. This reduction was partially inhibited by superoxide dismutase (SOD). Thyroxine (T4) was only minimally effective as a reductant in this system. The effect of T3 on mitochondrial oxidative phosphorylation may involve a direct redox mechanism.
