PROS1 and type 1 diabetes mellitus: Cytochrome c1 (a heme protein)(control/T1DM = 1.14, DM/AFB1 = 1.63), ATP synthase subunit beta (ATP5B) (control/T1DM = 0.92, DM/AFB1 = 1.58), and ATP synthase (H+ transport, mitochondrial F1 complex, gamma polypeptide 1) (control/T1DM = 0.78, T1DM/AFB1 = 1.92) and NADH dehydrogenase [ubiquinone] 1 beta subcomplex subunit 10 (control/T1DM = 0.91, T1DM/AFB1 = 1.50) are all involved in oxidative phosphorylation and were found to have similar or slightly decreased expression in the T1DM group as compared to controls.
