Scientists Create the most Accurate Epigenetic Clock Yet



If you are curious about how you age and whether you are naturally prone to develop certain diseases, then you probably want to pay more attention to the Epigenetic clock.

Scientists have developed the epigenetic clock which reveals information on the connection between a rapidly ageing brain and Dementia, including Alzheimer’s disease.

The epigenetic clock is to ageing what the circadian clock is to sleeping and waking cycles.

The scientists who are based at the University of Exeter analyzed brain tissue samples taken from human brains to come up with the epigenetic clock. The epigenetic clock is more accurate than others created using other tissue samples or blood samples.

According to lead researcher Professor Jonathan Mill, more research into Epigenetic clocks could unlock more understanding of the aging process.

“Our new clock will help us explore accelerated aging in the human brain. As we’re using brain samples, this isn’t a model that can be used in living people to tell how fast they’ll age. However, we can apply it to donated brain tissue to help us learn more about the factors involved in brain diseases such as dementia” says Mill.

Researchers studied the epigenetic markers responsible for DNA methylation within the human cortex. These epigenetic markers signal genes to switch on or go off.

The result is the most accurate epigenetic clock so far – one that predicts the biological age of the brain more accurately than ever before, according to Gemma Shireby of the University of Exeter.

The scientists eventually found 347 DNA methylation sites and it through these sites that they were able to make their accurate predictions within the cortex.

Their model held up when it was tested against 1,221 brain tissue samples collected by the Brains for Dementia Research cohort. The BRD cohort gets is funding from the Alzheimer’s Research UK and the Alzheimer’s Society on 1,175 blood samples.

The methylation data was instrumental in the creation of biomarkers for aging. These biomarkers for ageing are epigenetic clocks.

These clocks help scientists to understand how biological age and chronological change differ in terms of managing diseases like neurodegeneration as well as dementia among other brain types.

Researchers are excited because the new epigenetic body clock beats all its predecessors in its predictions of the biological age of the human brain.

They conclude that the reason why this new epigenetic clock is so accurate is that they used brain tissue samples relevant to the study of brain health. Because they were working with brain tissue, they were able to come up with a more accurately calibrated epigenetic clock to enable them to investigate dementia.
