We aim to understand why babies who are exposed to a poor diet in the womb are more likely to develop type 2 diabetes or become obese as adults. Obesity and associated conditions like type 2 diabetes are major health problems in the UK and western countries, influencing both quality and quantity of life. Approximately one third of the adult population in the UK are obese and over 4 million people in the UK are affected by diabetes. We know that how well a baby is nourished in the womb is one factor that influences how likely they are to develop type 2 diabetes and obesity as adults. Therefore, it is very important to understand how early diet has such effects as this may help us develop new medicines for these common conditions. We know that one way in which a poor diet during early life impacts on health is through “epigenetic” processes. This is the way the environment controls which parts of DNA are used to make proteins and therefore how well a cell works. Recent advances in genome research allow us to look at the epigenetic regulation of all the genes in our DNA (~22,000). In this project we will use these technological advances to identify faulty genes that cause metabolic diseases because of poor early diet.

我们的目标是了解为什么在子宫内饮食不良的婴儿更有可能患上 2 型糖尿病或成年后变得肥胖。肥胖和 2 型糖尿病等相关疾病是英国和西方国家的主要健康问题，影响生活质量和数量。英国约三分之一的成年人口肥胖，超过 400 万人患有糖尿病。我们知道，婴儿在子宫内的营养状况是影响他们成年后患 2 型糖尿病和肥胖的可能性的因素之一。因此，了解早期饮食如何产生这些影响非常重要，因为这可能有助于我们开发针对这些常见病症的新药物。我们知道，早年不良饮食对健康影响的一种方式是通过“表观遗传”过程。这就是环境控制 DNA 的哪些部分用于制造蛋白质以及细胞运作情况的方式。基因组研究的最新进展使我们能够研究 DNA 中所有基因（约 22,000 个）的表观遗传调控。在这个项目中，我们将利用这些技术进步来识别由于早期饮食不良而导致代谢疾病的错误基因。
