Interestingly, skeletal muscle displayed zero statistically different proteins in CKD and control mitochondrial proteomes; however, four proteins (CYB5R1, IDH3g, NDUFS7, and RMDN1) were found to be significantly correlated with OXPHOS conductance (p < 0.05, Figure 7A,D). This evidence concerns the gene NDUFS7 and chronic kidney disease.
