WebNov 15, 2024 · Postmortem human brain sections from patients with Parkinson's disease were subjected to imaging mass cytometry for individual astrocyte analysis of key OXPHOS proteins across all five complexes. Results We show the variability in the astrocytic expression of mitochondrial proteins between individuals. WebIn addition to its role in ATP production by OXPHOS, mitochondria fuel biosynthetic pathways through the tricarboxylic acid (TCA) cycle to produce lipids, proteins, and nucleic acids required in highly proliferating cells ( 3, 4, 7 – 11 ). Many studies have targeted OXPHOS as a therapeutic strategy in cancer ( 12 – 15 ).
