Biochem/physiol Actions

Carbonyl cyanide 3-chlorophenylhydrazone (CCCP) induces mitophagy in mammalian cells. CCCP suppresses the expression of few electron transport chain (ETC) proteins. Protonophore (H+ ionophore) and uncoupler of oxidative phosphorylation in mitochondria. Shown to have a number of effects on cellular calcium. Inhibits secretion of hepatic lipase and partially inhibits the pH gradient-activated Cl- uptake and Cl-/Cl- exchange activities in brush-border membrane vesicles.

Mitochondria play a central and multifunctional role in the progression of tumorigenesis. Although many recent studies have demonstrated correlations between mitochondrial function and genetic makeup or originating tissue, it remains unclear why some cancers are more susceptible to mitocans (anticancer...
