1450 genes reveal the signs of faster aging process and also a link between genes and factors such as diet, smoking and exercise.

The research team specifically looked for changes in gene expression, a process in which the information contained in genes is 'expressed' by reading the DNA sequence and creating RNA, and subsequently proteins.
By looking in blood, the researchers aimed to find easy to measure markers of human aging. This technique allowed them to develop a new method to predict people's 'biological age' and show that people with a biological age older than their actual age were more likely to have conditions such as high blood pressure or cholesterol.
Researcher Luke Pilling said that this study has discovered many genes that change in their patterns of expression with age. This study has not only given insights into aging mechanisms -- such as mitochondrial function -- but these techniques have potential use in prediction and treatment. The research is published online in Nature Communications.
