WebMar 6, 2024 · We confirmed that FCCP decreased Δψ m in vivo, as expected (Fig. 2 A), did not affect mitochondrial mass (Supplementary Fig. 1 C), and that FCCP exposure entirely prevented lifespan extension from DR (Fig. 2 B). Importantly, we chose a dose of FCCP that did not affect wildtype lifespan (Fig. 2 B&C). WebNov 1, 2024 · In this study, we analyzed a variety of respiration buffers and substrate combinations to determine the optimal conditions to support mitochondrial function through ADP-stimulated respiration and uncoupled respiration using FCCP.
WebMitochondrial membrane potential (MtMP) is a key indicator of mitochondrial activity, because it reflects the process of electron transport and oxidative phosphorylation, the driving force behind ATP production [56]. WebCCCP/FCCP is a lipid-soluble weak acid and a potent mitochondrial uncoupling agent that increases the proton permeability across the mitochondrial inner membrane, thus …
WebCarbonyl cyanide 4‐(trifluoromethoxy) phenylhydrazone (FCCP) induced depolarization in mitochondria and eliminates mitochondrial membrane potential. FCCP is a potent mitochondrial oxidative phosphorylation uncoupler and serves as positive control for depolarization of mitochondrial membrane or for apoptosis.
