Despite aggressive research aimed at understanding the myriad biochemical factors that are integrated to balance energy intake and expenditure to maintain normal body weight, obesity is increasing at an alarming rate, and the long-term success of prevention and intervention strategies is minimal. Because much of the scientific literature addressing obesity has originated with rodent models, there is considerable interest among researchers and funding agencies in the development of comparative animal models. Furthermore, numerous disparate results between rodent models and humans (i.e., adipsin, leptin, resistin, tumor necrosis factor-alpha, and other adipokines) have hindered the translation of rodent data into actionable technologies for humans. The pig is an exceptional restenosis model, and is emerging rapidly as a biomedical model for energy metabolism and obesity in humans because it is devoid of brown fat postnatally and because of their similar metabolic features, cardiovascular systems, and proportional organ sizes. This article highlights the current literature devoted to the development of porcine models for obesity and the metabolic syndrome, with a particular emphasis on the role of adipose tissue and adipokines in the regulation of energy balance and the inflammation associated with obesity.
尽管针对理解众多相互作用以平衡能量摄入与消耗从而维持正常体重的生化因素进行了积极研究,但肥胖现象仍在以惊人的速度增长,预防和干预策略的长期成效微乎其微。由于大量关于肥胖的科学文献都源于啮齿动物模型,研究人员和资助机构对开发比较动物模型有着浓厚兴趣。此外,啮齿动物模型与人类之间存在众多不同的结果(如脂肪酶、瘦素、抵抗素、肿瘤坏死因子-α以及其他脂肪因子方面),这阻碍了将啮齿动物数据转化为对人类可行的技术。猪是一种出色的再狭窄模型,并且正迅速成为人类能量代谢和肥胖的生物医学模型,因为其出生后缺乏棕色脂肪,且具有相似的代谢特征、心血管系统和比例相当的器官大小。本文重点介绍了目前致力于开发肥胖和代谢综合征猪模型的文献,特别强调了脂肪组织和脂肪因子在能量平衡调节以及与肥胖相关炎症中的作用。
