Sirt3 levels increase in human spinal cord of amyotrophic lateral sclerosis (ALS) patients. Human cortex (A,C,E,G,I,K) and spinal cord (B,D,F,H,J,L) were analyzed according to the canonical PPARGC1A (A,B), CNS-specific PPARGC1A (C,D), SIRT3 (E,F), SIRT4 (G,H) and SIRT5 (I,J) mRNA levels. mRNA levels were determined by qPCR and data was normalized to TBP and POLR2A, n = 10–12. SIRT3 protein levels were also determined in the human cortex (K) and spinal cord (L). Data was normalized to total protein amount determined by MemCode staining, n = 12–15. Analysis was performed by the nonparametric Mann-Whitney test. Data are shown as mean ± SEM. ns = P > 0.05, *P ≤ 0.05, **P ≤ 0.01.
