Figure 1.ApoE regulates the PGC-1α-Sirt3 pathway. Temporal lobes were freshly collected from 12-month-old ApoE4 mice and age-matched ApoE3 mice. (A–C) The levels of PGC-1α and Sirt3 were evaluated and normalized with an internal control (β-actin) in Western blot. (D) NAD+/ NADH ratio was measured and analyzed using the NAD+/ NADH assay kit. (E) ATP levels were measured using the ATP assay kit and normalized with brain tissue wet weight (Luminescent counts/ brain tissue weight). N= 8 for each group, *p< 0.05, **p< 0.01.
