Effect of mutEphA4-Fc treatment on SOD1G93A mice in functional tests and disease onset. (A) Kaplan Meier plot of ages (in days) of mutEphA4-Fc treated and saline control groups, in which the animal reached its peak body weight. The mean disease onset in the mutEphA4-Fc-treated group was delayed by about one week, compared with that in the saline control group; however, this difference was not statistically significance (log-rank test; p = 0.15). (B) Rotarod test values for mutEphA4-Fc treated and saline control groups show better performance of the mutEphA4-Fc treatment group from week 17 to week 23, compared with the control group (n = 8 per group; two-way ANOVA with Fisher’s LSD test at each age; *p < 0.05; **p < 0.01; ***p < 0.001). (C) Hind-limb grip strength; significant improvements in grip strength are seen in mutEphA4-Fc-treated SOD1G93A mice versus saline-treated mice at 9 weeks and 18–21 weeks of age. (two-way ANOVA with Fisher’s LSD test at each age; *p < 0.05; ***p < 0.001). (D) Kaplan Meier plot of survival time (in days) of mutEphA4-Fc-treated and saline control groups. The mutEphA4-Fc treatment group displayed a longer median survival time compared with the control group; however, this difference was not statistically significant. (log-rank test; p = 0.19). Data are expressed as mean ± SEM; n = 8 per group.
