An international group of researchers examined expression of genes in blood samples from 15,000 people.
New research has shed light on the molecular changes that occur in our bodies as we age. In the largest study of its kind, an international group of researchers, including experts from the University of Exeter’s Medical School, examined expression of genes in blood samples from 15,000 people across the world.
They found 1,450 genes that are linked to aging, and also uncovered a link between these genes and factors such as diet, smoking and exercise. Whilst the underlying causes of human aging are largely unknown, growing old increases the risk of diseases such as cancer, heart disease, and stroke — 3 of the leading causes of death.
The research team specifically looked for changes in gen...
