(A) Percentage of flies that climbed 4 cm in 20 seconds for Nup62, Nup214, and Nup43-overexpressing (Nup62 OE, Nup214 OE and Nup43 OE) animals compared to eGFP control (n = 3 trials, 10 animals per trials; ***p < 0.001, *p < 0.01, *p < 0.05). (B) Quantification of climbing velocity (cm/s) of Nup62 OE, Nup214 OE, and Nup43 OE flies compared to eGFP controls (n = 3 trials, 10 animals per trials, ***p < 0.001, **p < 0.01, *p < 0.05). (C) Kaplan-Meier survival curve of flies expressing Nup62 OE, Nup214 OE, Nup43 OE, Nup62/Nup214 OE, Nup62/Nup43 OE or eGFP control in motor neurons. (n = 60–80, ****p < 0.0001). (D, E) qPCR analysis of Nup62 and Nup214 mRNA levels in flies expressing Nup62 RNAi, Nup214 RNAi or eGFP controls (n = 3, **p < 0.01, ***p < 0.001). (F, G) Adult Drosophila expressing Nup62 RNAi or Nup214 RNAi in neuronal cells exposed to repeated traumatic brain injury (TBI) were raised on RU486 (+ RU486) or ethanol (-RU486) treated food for 20 days before motor assays. Quantification of (F) percentage of flies that climbed 4 cm in 20 s (n = 3 trials, **p < 0.01, ***p < 0.001) and (G) climbing velocity (cm/s) (n = 3 trials, *p < 0.05, **p < 0.01). Log-rank with Grehan-Breslow-Wilcoxon tests were performed to determine significance for panel C, while one-tailed t-tested was used in panel D, E, F, and G. All quantifications represent mean ± s.e.m.
