Figure 3. DPI extends lifespan of C. elegans. (A) Survival curves at different concentrations of DPI: untreated control (FUdR alone) (blue), 5 nM (red) and 20 nM (green). Statistical analysis was performed using Log-rank (Mantel-Cox), **p < 0.01 (control vs. 5 nM; control vs. 20 nM). (B) Median survival and maximal lifespan are represented. Experiments were carried out in triplicate with 15 worms for each replicate.
