Fig. 4. Reduction in mitochondrial-DNA encoded proteins in a MRPL40 heterozygous line.

Fig. 4

a, b Western blot of MRPL40, VDAC, SDHA, MT-ND1, cytochrome b, and COX1 from iPSC-derived neurons at differentiation day (DD) 21. In the MRPL40+/mut, there is decreased expression of MRPL40, and the mitochondrial DNA-encoded proteins MT-ND1, cytochrome b, and COX1, but no differences in the nuclear-encoded proteins VDAC and SDHA. c Quantitative PCR of MRPL40, VDAC, MT-ND1, Cytochrome b and COX1. In MRPL40+/mut, there is a small but significant decrease in expression of MRPL40, and no change in levels of the other transcripts. * = p < 0.05, NS—not significant. For a and b, MRPL40 (N = 7), VDAC1 (N = 5), SDHA (N = 3), MT-ND1 (N = 8), cytochrome b (N = 6), and COX1 (N = 5). For c, N = 3.
