The new obesity genes

Article Abstract:

Genetic abnormalities found in both animal and human research may contribute to obesity. Researchers have identified three obesity genes in mouse models, the agouti protein, the Ob protein, and the fat gene. In contrast, genetic evidence in human obesity seems to be much more complex. Possible contributing factors to total body fat include DNA variations of apolipoproteins, uncoupling protein, adrenergic receptors, and lipoprotein lipase. Five human genes may be linked to abdominal fat accumulations. Fat deposits in certain parts of the body has also been linked to DNA polymorphisms, such those for insulin, apolipoproteins, and adrenergic receptors.
