Figure 5. Inhibition of the Small GTPase rab-10 Increases Autophagy.

Figure 5

(A) Average number of LGG-1::GFP-containing puncta in N2 wild-type animals (WT) fed either control bacteria or bacteria expressing daf-2 (as a control) or rab-10 dsRNA for two generations. p < 0.0001 for either daf-2 or rab-10 RNAi treatment compared to control RNAi treatment, unpaired, two-tailed t-test. n, total number of seam cells observed. Error bars: ±SEM. See Figure 1 for details. Please see Table S1 for quantification of all data.

(B) Average number of LGG-1::GFP-containing puncta in rab-10(ok1494) mutants compared to N2 wild-type animals (WT), p < 0.0001, unpaired, two-tailed t-test. n, total number of seam cells observed. Error bars: ±SEM. Please see Figure 1 for details. Please see Table S1 for quantification of all data.

(C) Survival curves of rab-10(ok1494) animals fed either control bacteria or bacteria expressing bec-1 or vps-34 dsRNA during adulthood at 20 °C. Mean lifespan was 27.9 d for control, 19.9 d for bec-1 RNAi, and 22.1 d for vps-34 RNAi, all pair-wise comparisons to control, p < 0.0001, Log-rank (Mantel-Cox) test. This experiment was performed two times. Please see Table 3 for additional data.

(D) Survival curves of N2 wild-type animals (WT) fed either control bacteria or bacteria expressing bec-1 or vps-34 dsRNA during adulthood at 20 °C. These assays were performed at the same time as the rab-10 lifespan analysis shown in Figure 5C. Mean lifespan was 22.9 d for control, 23.6 d for bec-1 RNAi, and 24.5 d for vps-34 RNAi, pair-wise comparison to control, p = 0.057 and p = 0.16, respectively, Log-rank (Mantel-Cox) test. Please see Table 1 for additional data.
