Major breakthrough in aging
Posted: Fri Jan 13, 2023 2:38 pm
"An international study 13 years in the making demonstrates for the first time that degradation in the way DNA is organized and regulated — known as epigenetics — can drive aging in an organism, independently of changes to the genetic code itself.The work shows that a breakdown in epigenetic information causes mice to age and that restoring the integrity of the epigenome reverses those signs of aging."
In other words, they made young mice old and made old mice young again.
“This is the first study showing that we can have precise control of the biological age of a complex animal; that we can drive it forwards and backwards at will,” said Dr. David Sinclair [yup, him].
The study was published in Cell, the leading journal in biochemistry and molecular biology.
