Study describes novel aging clock trained to predict human age

Deep Longevity, a Hong-Kong based longevity startup, has published their research on the epigenetics of aging in the Aging and Disease journal.

The article about DeepMAge describes a novel aging clock that was trained to predict human age on more than 6'000 DNA methylation profiles. By analyzing the methylation patterns it can estimate human age within a 3-year error margin, which is more accurate than any other human aging clock.

Aging clocks boom started in 2013 when the first DNA methylation aging clocks by Horvath and Hannum were published. They have proven to be an indispensable tool in aging research, letting scientists understand its mechanisms and develop longevity interventions.

Unlike its predecessors, DeepMAge is a neural network that may prove to be more efficient in some other ways apart from prediction accuracy. In the original paper, DeepMAge deems people with certain conditions to be older, which may be useful for the development of early diagnostics tools.

For example, women with ovarian cancer are on average predicted 1.7 years older than healthy women of the same chronological age, and likewise, multiple sclerosis patients are predicted 2.1 years older. Similar results have been obtained for several other conditions: irritable bowel diseases, dementia, obesity.

Higher age predictions indicate a faster pace of aging in these conditions, which begs the question: is a higher aging rate a precondition to them or is it just an epigenetic footprint of the harm they cause? The authors plan to further investigate the links between epigenetics and longevity using DeepMAge.

Aging clocks have come a long way since the first works by Horvath and Hannum in 2013. We are happy to contribute to this research field. Now, we are going to explore how epigenetic aging can be slowed down with the interventions available to consumers".

Neural network architecture, which DeepMAge is based on, can be modified to digitally emulate the effects of fasting, taking longevity supplements, physical training, and other lifestyle changes.
