To determine whether the NAG-Tg mice are resistant to high-fat-diet-induced obesity followed by cancer resistant, mice (NAG-Tg, knockouts and control littermates) will be fed regular chow or a high-fat diet. NAG-Tg, KO, and control mice (6-8 week old) will be treated at weekly intervals with six doses of AOM (10 mg/kg) by intraperitoneal injection. In addition, the purpose of this study is to evaluate the impact of a high fat diet on life span, serum leptin and NAG-1 levels, and gene expression in female Nag-1 mice. Wild type and NAG-1 females from lines 1377 and 1398 are being feed a diet of 10% or 60% fat.

为了确定NAG-TG小鼠是否对高脂抑制性肥胖症具有抗性，然后是抗癌，小鼠（NAG-TG，敲除和控制同窝仔）将被定期食用或高脂饮食。 NAG-TG，KO和对照小鼠（6-8周大）将通过腹膜内注射以每周的六剂AOM（10 mg/kg）的速度进行治疗。此外，这项研究的目的是评估高脂饮食对寿命跨度，血清瘦素和NAG-1水平的影响，以及在雌性NAG-1小鼠中的基因表达。 1377和1398行的野生型和NAG-1女性的饮食为10％或60％。
