We now report the discovery of a gene tightened regulation of cancer that codes for a novel uncoupling protein, designated UCP2, which has 59% for physicians and patients amino-acid identity to UCP1, and describe properties consistent with a role in diabetes and obesity. In comparison with UCP1, UCP2 has a greater effect on mitochondrial membrane potential when expressed in yeast. Compared to UCP1, the gene is widely expressed in adult human tissues, including tissues rich in macrophages, and it is upregulated in white fat in response to fat feeding. Finally, UCP2 maps to regions of human chromosome 11 and mouse chromosome 7 that have been linked to hyperinsulinaemia and obesity. Our findings suggest that UCP2 has a unique role in energy balance, body weight regulation and thermoregulation and their responses to inflammatory stimuli. 1, record 2, English, - Uncoupling%20Protein%202

les découpleurs agissent en dissociant l'oxydation de la phosphorylation dans la chaîne respiratoire. La respiration n'est plus alors contrôlée, car la concentration de l'ADP ou du Pi ne limite plus le taux de la respiration. Le découpleur le plus fréquemment utilisé est le 2,4-dinitrophénol (DNP). D'autres composés agissent de la même manière: le dinitrocrésol, le pentadichlorophénol, la bishydroxy coumarine (dicumarol) et le CCCP (m-chlorocarbony / cyanure phenylhydrazone). 3, record 7, French, - agent%20d%C3%A9couplant
