Anoxia hormesis protects from irradiation-induced oxidative damage in a cross tolerance hormetic framework. The strong protective effect of anoxia was evident at all doses (B, C, & D) tested but was more dramatic at 400 Gy (D), where the irradiated control flies die within 24 hrs. but anoxia hormesis flies live more than two months. Sex differences can be seen at all doses and females tend to live longer at higher doses (F; Figure 2 from López-Martínez and Hahn 2014).
