Analysis of pqe-1 mutants under different stress-inducing conditions. Refer to Fig. 1 for a description of box plot. (A) RT-qPCR analysis showing increased expression of hsp-4 (p = 0.0128), hsp-6 (p < 0.0001), hsp-16.2 (p = 0.0012) and xbp-1(p < 0.0001) in pqe-1(ok1983) day-1 adults. (B) pqe-1(ok1983) animals exhibited a reduced electrotaxis speed compared to wild-type N2 (p = 0.0053) (C) The speed was further decreased following treatments with 125 μM PQ (p = 0.007). (D) The speed of pqe-1(ok1983) was not significantly different from untreated control (p = 0.2461). At 2 μg/mL exposure, pqe-1 mutants showed a significant decrease in speed (p = 0.0001). (E) The electrotaxis speed of ifg-1 RNAi in control and pqe-1(ok1983) animals. The ifg-1 RNAi had no effect on control animals (p = 0.4193) or pqe-1 mutants (p = 0.6676). The numbers of animals were (B) N2: n = 3 batches, pqe-1 n = 3 batches. (C) pqe-1 untreated: n = 44, pqe-1 + PQ 125 μM: n = 30. (D) pqe-1: n = 16, pqe-1 + 1 μg/mL Tuni n = 21, pqe-1 + 2 μg/mL Tuni n = 21. (E) Control, L4440: n = 47, Control, ifg-1 RNAi: n = 66, pqe-1, L4440: n = 41, pqe-1, ifg-1 RNAi: n = 44. Data was analyzed using one-way ANOVA with Tukey’s post hoc test (A), one-way ANOVA with Dunnett’s post hoc test (D), and unpaired Student’s t-test (B,C,E).
