The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
We show these changes can be reversed by OSK-mediated rejuvenation. With an ability to drive aging in both the forward and reverse directions, we conclude that loss of epigenetic information is a cause of aging in mammals.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
In recent years, the concept of in vivo epigenetic reprogramming, using a subset such as OSK (Oct4, Sox2, Klf4), has been explored as a way to rejuvenate cells while preserving their specialized roles
“Based on our novel mouse population (= >80 years of age in humans) & previous studies in younger mice, we envision therapeutic rejuvenation in aging humans, first in specific age-related disease settings & later for therapeutic healthspan & lifespan extension.”
Partial reprogramming with virally-delivered OSK genes rejuvenates senescent cells, restores tissue integrity, heals wounds & extends lifespan in mice.
