DNA clock helps
to get measure of people's lifespans

Summary:
A biological clock
that provides vital clues about how long a person is likely to live has been
discovered by researchers. Researchers studied chemical changes to DNA that
take place over a lifetime, and can help them predict an individual's age. By
comparing individuals' actual ages with their predicted biological clock age,
scientists saw a pattern emerging.

scientists have
identified a biological clock that provides vital clues about how long a person
is likely to live.
Researchers studied chemical changes to DNA that take place over a
lifetime, and can help them predict an individual's age. By comparing individuals'
actual ages with their predicted biological clock age, scientists saw a pattern
emerging.
People whose biological age was greater than their true age were more
likely to die sooner than those whose biological and actual ages were the same.
Four independent studies tracked the lives of almost 5,000 older people for
up to 14 years. Each person's biological age was measured from a blood sample
at the outset, and participants were followed up throughout the study.
Researchers found that the link between having a faster-running biological
clock and early death held true even after accounting for other factors such as
smoking, diabetes and cardiovascular disease.
Scientists from the University of Edinburgh, in collaboration with
researchers in Australia and the US, measured each person's biological age by
studying a chemical modification to DNA, known as methylation.
The modification does not alter the DNA sequence, but plays an important
role in biological processes and can influence how genes are turned off and on.
Methylation changes can affect many genes and occur throughout a person's life.
Dr Riccardo Marioni, of the University of Edinburgh's Centre for Cognitive
Ageing and Cognitive Epidemiology, said: "The same results in four studies
indicated a link between the biological clock and deaths from all causes. At
present, it is not clear what lifestyle or genetic factors influence a person's
biological age. We have several follow-up projects planned to investigate this
in detail."
The study's principal investigator, Professor Ian Deary, also from the
University of Edinburgh's Centre for Cognitive Ageing and Cognitive
Epidemiology, said: "This new research increases our understanding of
longevity and healthy aging. It is exciting as it has identified a novel
indicator of aging, which improves the prediction of lifespan over and above
the contribution of factors such as smoking, diabetes, and cardiovascular
disease."
The study is published in the journal Genome Biology.
