The longevities of hypoxic Canton S and Oregon R flies are diet and GC7 sensitive. Flies were fed on different diets as indicated and survivorship curves were defined under chronic hypoxic conditions. Sample sizes are indicated in parentheses. L-ornithine and GC7 were used at 10 mM. Percentage changes in longevity by GC7 are indicated. A log rank test was used to compare survivorship curves: **: p < 0.0001. The survivorship curves of flies fed on a 10% sucrose medium were truncated for clarity. Median and maximum longevities of hypoxic flies fed on a 10% sucrose diet were: Canton S, 8 days and 22 days, Oregon R, 14 days and 22 days.
