肥胖症是目前日益突出的营养学问题。己知肥胖症与糖尿病、高血压、高血脂甚至肿瘤的发病有关。肥胖症的发生原因及机理尚未明确,故对肥胖症的研究已成为医学领域的一个重要课题。随着分子生物学技术的发展,目前已发现多个与肥胖症有关的基因,其中以肥胖基因及其产物ＬＥＰＴＩ Obesity is an increasingly prominent nutrition issue. It is known that obesity is associated with the onset of diabetes, hypertension, hyperlipidemia, and even cancer. The causes and mechanisms of obesity are not yet clear, so the research on obesity has become an important issue in the medical field. With the development of molecular biology technology, a number of genes related to obesity have been found. Among them, the obesity gene and its product LEPTI
