| pubmed-article:6295765 | pubmed:abstractText | Possible mechanisms are evaluated for the acute regulation of the hamster brown-fat mitochondrial proton-conductance pathway which is active during non-shivering thermogenesis. Isolated mitochondria are incubated under conditions designed to approximate to the non-thermogenic state, and the effect of the steady infusion of fatty acids or acyl derivatives upon respiration, membrane potential and membrane proton conductance is monitored continuously. Fatty acids increase the proton conductance with no detectable threshold concentration, allowing the generated acyl carnitine to be rapidly oxidized. The extent of depolarization and of respiratory increase is a function of the rate of infusion. Immediately infusion is terminated the conductance decreases, the mitochondria repolarize and respiration returns to the initial rate. Infusion of acyl-CoA and acylcarnitine cause only a slight depolarization or respiratory increase after high concentrations of these derivatives have accumulated. Any factor which decreases the rate of conversion of fatty acid to acyl-CoA potentiates the conductance increase. An effect of acyl-CoA upon chloride permeability is not specific to brown-fat mitochondria. Fatty acids infused into rat liver mitochondrial incubations produced a small conductance increase, comparable to that of acyl-CoA or acylcarnitine. It is concluded that fatty acids are the most plausible acute regulators of the proton conductance. The relation to the brown-fat-specific 32000-Mr protein is discussed. | lld:pubmed |
