Mitochondria Isolated from Rat Brown Adipose Tissue
Mitochondrial fractions, relatively free from contsmination by other cytopla-~mic structures, have been isolated by differential centrifugation from homogenates of brown adipose tissue from starved rats. It was possible in such fractions to distinguish two types of mitochondria in this tissue. Type I mitochondria, when morphologically intact, are limited by a bilaminar membrane and show regular...

متن کاملSodium-induced calcium release from mitochondria in brown adipose tissue.
Coupled mitochondria of brown adipose tissue can accumulate Ca2+ if a substrate is present. The Ca2+ is released by addition of 20 mM Na+, but not by addition of K+ or choline +. Energy-dissipating Na+-induced Ca2+ cycling occurs maximally with 20 mM Na+ and 10 microM Ca2+. In brown adipocytes, the Ca2+ ionophore A23187 and the Na+ ionophore monensin increase respiration if substrate is added, ...
متن کاملMitochondrial fission: firing up mitochondria in brown adipose tissue.
Brown adipose tissue (BAT) is an important site for energy expenditure, for instance to generate heat in times of cold exposure. BAT expansion and activation can increase energy dissipation of an organism. This involves the coordinated activation of mitochondrial metabolism and heat generation through uncoupling of oxidative phosphorylation. In this issue of The EMBO Journal, the Shirihai group...
متن کاملBrown adipose tissue
Obesity is currently a global pandemic, and is associated with increased mortality and co-morbidities including many metabolic diseases. Obesity is characterized by an increase in adipose mass due to increased energy intake, decreased energy expenditure, or both. While white adipose tissue is specialized for energy storage, brown adipose tissue has a high concentration of mitochondria and uniqu...
