ATP5F1B and posterior cortical atrophy: Our results showed that the expression of carnitine palmitoyl transferase 1 (CPT1), cytochrome c oxidase subunit 4 (COXIV), ATP synthase subunit alpha and beta (ATP5A and B), and mitochondrial import receptor subunit (TOM20) is increased in 22Rv1 cells, suggesting that PCa increases the import of mitochondrial proteins (via TOM20), mitochondrial acyl-CoA transport (via CPT1), and ATP production (via COXIV, ATP5A, and ATP5B) (Figure 1A).
