肥胖是一种公共健康危机。需要新的方法来改善其后果,因为推动它的社会和经济因素发生逆转的可能性很小。中性脂肪在肝脏的病理性堆积(肝脏脂肪变性)是一个与肥胖相关的问题,其分子基础尚不清楚,缺乏有效的治疗方法。在这里,我回顾了斑马鱼是如何被利用来发现有助于正常肝脏脂肪处理的新因素的,斑马鱼是一种强大的模式生物,长期用于研究脊椎动物的发育计划。注意饮食模型和个体突变体。我推测肝脏、脂肪组织和肠道微生物群中的非肝细胞居留物在肝脏脂肪变性的发展中可能起到了作用。强调的工作和未来的方向可能会导致对过度肝脂状态的发病机制和治疗的新见解。
Obesity is a public health crisis. New methods for amelioration of its consequences are required because it is very unlikely that the social and economic factors driving it will be reversed. The pathological accumulation of neutral lipids in the liver (hepatic steatosis) is an obesity-related problem whose molecular underpinnings are unknown and whose effective treatment is lacking. Here I review how zebrafish, a powerful model organism long-used for studying vertebrate developmental programs, is being harnessed to uncover new factors that contribute to normal liver lipid handling. Attention is given to dietary models and individual mutants. I speculate on the possible roles of non-hepatocyte residents of the liver, the adipose tissue, and gut microbiome on the development of hepatic steatosis. The highlighted work and future directions may lead to fresh insights into the pathogenesis and treatment of excess liver lipid states.
