表观遗传信息可以通过哺乳动物的生殖细胞遗传,并代表了一个合理的环境信息的跨代载体。为了测试哺乳动物是否会发生环境信息的跨代遗传,我们对小鼠中对父亲饮食有反应的基因进行了表达谱筛选。后代的男性喂养低蛋白饮食表现出升高的肝脏表达的许多基因参与脂质和胆固醇的生物合成,胆固醇酯的水平降低,相对于后代的男性喂养控制饮食。后代肝脏的表观基因组分析显示,取决于父亲饮食,胞嘧啶甲基化发生了许多适度(约20%)变化,包括关键脂质调节剂PPARα的可能增强子甲基化的可重复变化。这些结果,结合最近的人类流行病学数据,表明父母的饮食可以影响后代的胆固醇和脂质代谢,并定义了一个模型系统来研究遗传表观基因组的环境重编程。
Epigenetic information can be inherited through the mammalian germline, and represents a plausible transgenerational carrier of environmental information. To test whether transgenerational inheritance of environmental information occurs in mammals, we carried out an expression profiling screen for genes in mice that responded to paternal diet. Offspring of males fed a low protein diet exhibited elevated hepatic expression of many genes involved in lipid and cholesterol biosynthesis, and decreased levels of cholesterol esters, relative to the offspring of males fed a control diet. Epigenomic profiling of offspring livers revealed numerous modest (~20%) changes in cytosine methylation depending on paternal diet, including reproducible changes in methylation over a likely enhancer for the key lipid regulator PPARα. These results, in conjunction with recent human epidemiological data, indicate that parental diet can affect cholesterol and lipid metabolism in offspring, and define a model system to study environmental reprogramming of the heritable epigenome.
