MT-RNR2 and age-related macular degeneration: Western blotting analyses comparing protein levels of Complex I subunit (NADH-coenzyme Q oxidoreductase), Complex II subunit (Succinate-coenzyme Q oxidoreductase), Complex III subunit (Coenzyme Q-cytochrome c oxidoreductase), Complex IV subunit (Cytochrome c oxidase), and Complex V subunit (ATP synthase) were performed for untreated and SHLP2-treated normal and AMD cybrids (Fig. 2A) (Fig. S1A, S1B, S2A, and S2B).
