Bacteria with obesity gene. Gloved hand with petri dish culture of recombinant bacteria containing the UCP2 gene linked to human obesity & diabetes. White dots are bacterial colonies containing this gene. The UCP2 gene was discovered by French and American scientists in 1997. Genetically engineer- ed into bacteria, it is being cloned for study. UCP2 (uncoupling protein 2) gene occurs on human chromosome 11 & is believed to govern the rate at which the body burns off fat. The protein produced by this gene occurs in muscles and fat. It enables cells to burn off calories as heat. Obese humans have lowered levels of this protein. Future drugs for weight loss may include this protein.
