Figure 3. Influence of heart salt gene overexpression and LTE on the climbing ability and lifespan in Drosophila. (A) The climbing index in 1-week old, 3-week old, and 5-week old flies. (B) Fly population survival (%)curve. The leftmost curve represents the salt-OE group, of which flies had the shortest lifespan. (C) The average lifespan. (D) The climbing endurance in 1-week old flies. (E) The climbing endurance in 3-week old flies. (F) The climbing endurance in 5-week old flies. (G) The climbing endurance of Salt-control. (H) The climbing endurance of Salt-OE. (I) The climbing endurance of Salt-OE+E. The leftmost curve represents the salt-OE group, of which flies had the shortest lifespan. For climbing ability measurement, the sample size was about 100 flies for each group. For climbing index, using a one-way analysis of variance (ANOVA) followed by an LSD test among these groups. For lifespan, the sample size was 200-220 flies for each group. P-values for lifespan curves and climbing endurance curves were calculated by the log-rank test. Data are represented as means ± SEM. *P<0.05; **P <0.01.
