“Loss of epigenetic information as a cause of mammalian aging”

In this pioneering study published January 12, 2023 in Cell, Professor Sinclair and colleagues report that loss of epigenetic information causes and accelerates aging, and that these changes are reversible via epigenetic reprogramming. This finding supports Professor Sinclair’s Information Theory of Aging–and the notion that aging is reversible.

“Reprogramming to recover youthful epigenetic information and restore vision”

As detailed in this landmark study published December 2, 2020 in Nature, Professor Sinclair and colleagues have used epigenetic reprogramming to reverse vision loss in aged mice afflicted with glaucoma. This feat demonstrates that epigenetic reprogramming can be used to promote tissue regeneration and improve tissue function in live animals.
