dmm"Gene Therapy-Mediated Partial Reprogramming Extends Lifespan and Reverses Age-Related Changes in Aged Mice"
A Feb 24 paper seems to claim an impressive result in "wild-type" mice via a partial cellular reprogramming protocol, which includes cyclic administration of doxycycline for temporal control of reprogramming, and which does not seem to be particularly cancer-inducing (that's usually a big problem with cellular reprogramming).. 124-week male mice, Doxycycline-treated controls average survival till 133 weeks, treatment group average survival till 142.5 weeks (for a human something like this would roughly double remaining life expectancy of a 75-year old male from about 10 more years to about 20 more years if equally efficient).
It would be nice if this turns out to be a real breakthrough (we have learned from experience to be very skeptical about claims in this field of study).
