Small-Molecule Mn Antioxidants in Caenorhabditis elegans and Deinococcus radiodurans Supplant MnSOD Enzymes during Aging and Irradiation

ABSTRACT Denham Harman’s oxidative damage theory identifies superoxide (O2•−) radicals as central agents of aging and radiation injury, with Mn2+-dependent superoxide dismutase (MnSOD) as the principal O2•−-scavenger. However, in the radiation-resistant nematode Caenorhabditis elegans, the mitochond...
