Adaptive thermogenesis in hummingbirds.
The occurrence of non-shivering thermogenesis in birds has long been a controversial issue. Although birds are endothermic vertebrates, sharing with mammals (placental mammals and marsupials) a common ancestor, they do not possess brown adipose tissue or a similar type of tissue, unlike their mammalian counterparts. Some bird species are, however, able to withstand very low ambient temperatures...
متن کاملAdaptive thermogenesis: Orchestrating mitochondrial biogenesis
The biogenesis of mitochondria requires products of the nuclear and mitochondrial genomes. Recent studies of adaptive thermogenesis have shown how mitochondrial proliferation and respiratory activity in brown fat and skeletal muscle are directed by the transcriptional coactivator PGC-1.
متن کاملNeuronal Control of Adaptive Thermogenesis
The obesity epidemic continues rising as a global health challenge, despite the increasing public awareness and the use of lifestyle and medical interventions. The biomedical community is urged to develop new treatments to obesity. Excess energy is stored as fat in white adipose tissue (WAT), dysfunction of which lies at the core of obesity and associated metabolic disorders. By contrast, brown...
متن کاملWeight loss, weight maintenance, and adaptive thermogenesis.
BACKGROUND Diet-induced weight loss is accompanied by adaptive thermogenesis, ie, a disproportional or greater than expected reduction of resting metabolic rate (RMR). OBJECTIVE The aim of this study was to investigate whether adaptive thermogenesis is sustained during weight maintenance after weight loss. DESIGN Subjects were 22 men and 69 women [mean ± SD age: 40 ± 9 y; body mass index (B...
متن کاملAdaptive thermogenesis: Turning on the heat
Brown adipocytes play important roles in the regulation of fat storage and body temperature, by virtue of their ability to uncouple mitochondrial fuel oxidation and ATP synthesis. The discovery of a tissue-specific transcriptional coactivator provides new insights into the regulation of thermogenesis by brown adipocytes.
