PGC-1α improved motor performance and survival in SOD1 mutant mice. (A) Motor performance as measured by rotarod test in WT, PGC-1α, SOD1-G93A and SOD1-G93A/PGC-1α animals (**p < 0.01); (B) Survival analysis of WT, PGC-1α, SOD1-G93A and SOD1-G93A/PGC-1α animals (**p < 0.01 by Mantel-Cox test); (C) Average body weight of WT, PGC-1α, SOD1-G93A and SOD1-G93A/PGC-1α animals; (D) Average weight loss (percentage of peak weight) of SOD1-G93A and SOD1-G93A/PGC-1α animals (*p < 0.05).
