The redox index of NADH in the PINK1 KD cells was significantly more oxidized than in controls (PINK1 KD neurons, 54.9% ± 3.3%, n = 69, compared to control neurons, 25.2% ± 1.9%, n = 65; PINK1 KD neuroblastoma, 65.7% ± 4.1%, n = 41, compared to control neuroblastoma cells, 29.6% ± 2.3%, n = 39; PINK1 KO mouse neurons, 53.6% ± 4.7% (n = 99), compared to control mouse neurons, 23.4% ± 1.8%, n = 86; p < 0.001 for all type of the cells) (Figure 2). Here, PINK1 is linked to neuroblastoma.
