Death curves of two different biomarkers of aging coupled to tetanus toxin expression. Flies were kept at a density of 25 flies per sex and vial on lightly yeasted standard cornmeal food and passed every other day. Dead flies were counted daily. (A) DJ651-driven toxin expression leads to average survival times of 8 days for both males and females. Toxin expression is delayed in DJ634-driven flies, and therefore, average survival times increased to 18 days. (B) Compared with survivorship curves of Canton-S flies, DTT females live 80% shorter.
