Fig. 3. Reductions in mitochondrial-DNA encoded protein in 22qSZ.

Fig. 3

a–d Protein levels, by western blot and relative to β-actin, of MRPL40, VDAC, SDHA, MT-ND1, cytochrome b, and COX1 in iPSC-derived neurons. While nuclear-encoded VDAC and SDHA were unchanged, the mitochondria-encoded proteins MT-ND1, cytochrome b, and COX1 were significantly reduced. e Quantitative PCR of MRPL40, VDAC, MT-ND1, cytochrome b, and COX1 shows decreased expression of MRPL40 but no change of VDAC, MT-ND1, cytochrome b, and COX1 in 22qSZ relative to control. f No difference of mitochondrial DNA copy number between 22qSZ and control in iPSC-derived neurons at differentiation day 21. N = 5 for control, N = 4 for 22qSZ; * indicates p < 0.05. NS—not significant.
