UCP1-independent thermogenesis in white adipose tissue of cold-acclimated Ucp1-/- mice.
Apart from UCP1-based nonshivering thermogenesis in brown adipocytes, the identity of thermogenic mechanisms that can be activated to reduce a positive energy balance is largely unknown. To identify potentially useful mechanisms, we have analyzed physiological and molecular mechanisms that enable mice, genetically deficient in UCP1 and sensitive to acute exposure to the cold at 4 degrees C, to ...
متن کاملWhite adipose tissue contributes to UCP1-independent thermogenesis.
Beta3-adrenergic receptors (AR) are nearly exclusively expressed in brown and white adipose tissues, and chronic activation of these receptors by selective agonists has profound anti-diabetes and anti-obesity effects. This study examined metabolic responses to acute and chronic beta3-AR activation in wild-type C57Bl/6 mice and congenic mice lacking functional uncoupling protein (UCP)1, the mole...

SMITH, ROBERT E., AND JANE C. ROBERTS. Thermogenesis of brown ad ipose tissue in cold-acclimated rats. Am. J. Physiol. 206( I > : 143-148. I g64.-Multilocular brown adipose tissue in the rat is shown to increase in both mass and respiratory rate, in vitro, during cold acclimation. By vascular convection the resulting heat is directly applied to the thoracocervical regions of the spinal cord, th...
متن کاملOnly UCP1 can mediate adaptive nonshivering thermogenesis in the cold.
Adaptive nonshivering thermogenesis may have profound effects on energy balance and is therefore therefore is a potential mechanism for counteracting the development of obesity. The molecular basis for adaptive nonshivering thermogenesis has remained a challenge that sparked acute interest with the identification of proteins (UCP2, UCP3, etc.) with high-sequence similarity to the original uncou...
متن کاملLeptin selectively reduces white adipose tissue in mice via a UCP1-dependent mechanism in brown adipose tissue.
We tested the hypothesis that leptin, in addition to reducing body fat by restraining food intake, reduces body fat through a peripheral mechanism requiring uncoupling protein 1 (UCP1). Leptin was administered to wild-type (WT) mice and mice with a targeted disruption of the UCP1 gene (UCP1 deficient), while vehicle-injected control animals of each genotype were pair-fed to each leptin-treated ...
