Adults were reared and tested in M9 medium plus 5 mM trehalose, which has previously been shown to extend lifespan and increase pump frequency late in life in C. elegans (Honda et al., 2010). Using an alternate electrophysiological readout of pumping, electrophayrngeograms (EPGs), we examined pump frequency at earlier time points than previously reported. Pumps were stimulated with 10mM 5HT in M9, recorded as EPGs in a microfluidic device, and analyzed using NemAnalysis software (NemaMetrix). Pump frequency in trehalose-treated animals was significantly higher in 11-day adults than in controls of the same age that were reared in parallel and tested on the same day (p<0.01; 1-tailed Mann-Whitney U-test; n = 5-8 worms at each age in each condition). This finding confirms, by an independent method, previously reported data (Honda et al., 2010). | Paper_evidence | WBPaper00050383 | |||||||

Remark | Of deprenyl, reserpine, and haloperidol, only reserpine could extend C. elegans lifespan by 31% at 25 deg C upon chronic treatment from embryo till death. At 20C, no significant lifespan extension was observed. Reserpine-treated worms had a mean life span of 17 days, in contrast to untreated worms with a mean life span of 13 days. | Paper_evidence | WBPaper00031694 | ||||||

NR treatment only increased mean lifespan by 3%, while BHB increased mean lifespan by 21%. Combination treatment increased mean lifespan by 18% that was not significantly different than the addition of BHB alone. | Lifespan experiments were then performed using the same treatments, but first administered at the L1 larval stage (Figure 1B) instead of the L4 stage. The results are summarized in Experiment 2 in Table 1. NR increased mean lifespan by 20% consistent with previous results of NR-mediated longevity (Mouchiroud et al., 2013) and suggesting the requirement of the full non-blunted UPRmt activated during larval development for the anti-aging effects. | Treatment with NR only during larval development increased mean lifespan by 28%, | Paper_evidence | WBPaper00065348 | |||||||

Ten L4 animals were manually transferred to individual plates seeded with S. marcescens. Plates were completely covered by bacteria to prevent animals from avoiding the bacteria. Adults were daily transferred to new plates and the number of eggs laid on each plate was counted every 24 hours until no more eggs were laid. Statistical analyses were performed using repeated measures ANOVA and Tukey's post-hoc test. S. marcescens from Carolina Biological Supply Company. | Paper_evidence | WBPaper00056577 | |||||

Ten L4 animals were manually transferred to individual plates seeded with S. marcescens. Plates were completely covered by bacteria to prevent animals from avoiding the bacteria. Adults were daily transferred to new plates and the number of eggs laid on each plate was counted every 24 hours until no more eggs were laid.

Remark | lipopolysaccharide (LPS) extracted from S. enterica stimulates gravid adults to lay more eggs in LPS-containing solution than those in M9 buffer only. Figure 1 shows that the worms that were exposed to 0.1 mg/ml LPS for 1 hour laid an average of 5.57 +/- 0.57 eggs (+/- one standard error; n = 101), which was significantly different than the response of the worms exposed to M9 buffer (1.87 +/- 0.25 eggs; n = 112). Exogenous serotonin at 1 mg/ml in M9 resulted in the laying of 8.40 +/- 0.60 eggs in one hour (n = 111 compared to the worms in M9). The magnitude of LPS-stimulated egg laying was not comparable to that of the serotonin one (p = 0.0005, indicating significant difference). | Paper_evidence | WBPaper00060230 | ||||||

Remark | "Animals on a high-glucose diet throughout their entire lifecycle have a delayed reproductive profile, with the median point of the fertile period (when 50% of the offspring have been produced) occurring later (Figs. 1C and 1E and Mondoux et al. 2011)." "In contrast to the effects of high-glucose diet on total offspring, which is a phenotype resulting from exposure during adulthood (Figs. 1A-B), we find that high-glucose diet during development is sufficient to delay the reproductive profile as much as exposure during the entire lifecycle." "High-glucose diet exposure only in development led to a 1-day delay in the reproductive profile (median at 3.6 days compared to 2.6 days for animals fed a control diet throughout the lifecycle; Figs. 1C and 1E), which was equal to the delay for animals exposed to glucose throughout their lifecycle (also median 3.6 days, Figs. 1C and 1E). High-glucose diet only in adulthood had a smaller but significant effect on reproductive timing (median 2.9 days; Figs. 1C and 1E), as these animals produced progeny more quickly than those exposed to glucose in development, but were still reproductively delayed compared to control diet. As we observed for total fertility, high-glucose diet only during L4 and the L4 to adult transition did not affect reproductive timing (Figs. 1D and 1F). These results suggest that both developmental and adult exposure to a high-glucose diet affect the reproductive profile, but that there is not an additive effect: high-glucose diet during adulthood does not further slow reproduction if the animal was exposed to high-glucose diet during development." | Paper_evidence | WBPaper00064301 | ||||||

Remark | lipopolysaccharide (LPS) extracted from S. enterica stimulates gravid adults to lay more eggs in LPS-containing solution than those in M9 buffer only. Figure 1 shows that the worms that were exposed to 0.1 mg/ml LPS for 1 hour laid an average of 5.570.57 eggs ( one standard error; n = 101), which was significantly different (p < 0.0001) than the response of the worms exposed to M9 buffer (1.870.25 eggs; n = 112). | Paper_evidence | WBPaper00060230 | ||||||

Remark | 100nM emodepside exposure (over 24 hours) elicited a flaccid paralysis, particularly apparent in the anterior of the worm, and a decrease in amplitude of the sinusoidal body shape. Emodepside inhibited body bends of wild-type worms after a shorter, 3 hour, incubation time but with a slightly higher IC50 (78 nM). | Paper_evidence | WBPaper00038239 | ||||||
