Epigenetic programming of metabolic health across the life-course

In plain English

AI plain-English summary

A baby’s diet in the womb can permanently alter how its DNA works, raising the risk of obesity and type 2 diabetes decades later. This matters because over 4 million people in the UK have diabetes, and a third of adults are obese. Doctors know that poor early nutrition is a factor, but they do not understand exactly how it leaves a lasting mark on the body’s metabolism. The missing piece is “epigenetics”—the system that switches genes on or off without changing the DNA sequence itself. A poor diet in the womb may mis-set these switches in ways that persist for life. This project will scan all 22,000 human genes to identify which ones become faulty due to poor early nutrition. If it succeeds, it could reveal specific molecular targets for new medicines that reverse or compensate for that early damage. That would shift prevention and treatment from general lifestyle advice toward precise, biology-based interventions for metabolic disease. This is fundamental science. It will not produce a drug tomorrow. But understanding how early environment reprograms gene activity has already transformed fields like cancer biology, and the same approach now promises to do the same for obesity and diabetes.

View original technical description
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.
