COX6C and post-traumatic stress disorder: In our study, we observed a significant downregulation of oxidative phosphorylation pathway-related genes, including NADH: ubiquinone oxidoreductase subunit A13 (Ndufa13), ubiquinol-cytochrome c reductase, complex III subunit XI (Uqcr11), cytochrome c oxidase subunit 6C (Cox6c), cytochrome c oxidase subunit 8A (Cox8a), and ATP synthase epsilon chain (Atp5e), in both InNs and ExNs in the hippocampus of PTSD mice.
