Announcing to the team we received acceptance at a top scientific journal of a 13 year study to test The Information Theory of Aging… 1/n #harvard
With this discovery, we’re able to drive aging forwards and backwards in a mouse, and see the underlying processes that we believe cause us to age 2/n
The goal is to slow and reverse aging in the human body, to treat diseases by addressing their cause rather than the symptoms 3/n
The study suggests that aging is like scratches on a CD that can be polished off, or like corrupted software that can be reinstalled to reverse aging, as described in Lifespan 4/n
I’m so proud of the 60 person team and of Dr. Jae-Hyun Yang, lead scientist this past decade. He’s the guy at the end, to my right 5/n
Jae revealed that he wrote me a resignation email in 2021, it was so physically and emotionally difficult for him (and his family). Fortunately he never sent it 🙏 6/n
The lessons: 1. Aim the highest you can imagine 2. Don’t listen to the naysayers, they will always criticize what’s new or threatening 3. Never, ever give up. Have grit 4. Collaborate with people smarter & more skilled than you. It takes a diverse team to do the impossible 7/n
5. Always aim to improve your work 6. Utilize new technologies 7. Believe in yeast 8. What you do is more important than how long it takes you 9. Surround yourself with people who share the same goals and work ethic 10. Stick to what you believe in. Never compromise 8/n
I was 39 when this project started in lab! In 2009, there was no such thing as a DNA methylation clock or CRISPR. It was initiated by postdoc Dr. Phillip Oberdoerffer and our lab’s manager Dr. Luis Rajman. Thanks guys. 9/n
The paper was rejected about 3 years ago. We improved the work for another year. We appealed. We won the appeal. We did another year of work. We merged the two papers, we did another year of work. We resubmitted & were accepted in Dec 2022. Publication date Feb 2023. 10/n
We dedicate the work to Drs. Michael Bonkowski (right) and Norm Wolf, who we lost on the journey
Be suspicious of anyone who claims resveratrol has no health benefits. New papers showing efficacy in rodents & humans are published often, and the debate b/w my lab & @pfizer about the molecular mechanism of Sirt1 activation was settled in 2013 🤷♂️
On November 4th, 2022, the US Food and Drug Administration (FDA) published a letter regarding the marketing and sales of nicotinamide mononucleotide (NMN) as a supplement to boost NAD levels 1/15
I am deeply grateful for your patience while I’ve gathered information to share with you about the impact of this decision. I know many of you are worried about what this means about the safety of NMN, and the possible limitations to the availability of NMN supplements 2/15
While NAD boosters such as NMN have become popular as supplements, in part because of my research, I am not, and have not, been involved as an owner, cofounder, investor, shareholder, marketer, spokesperson or sponsor of any company that sells NAD boosters as supplements 3/15
New lab paper: In 2003, we found activators of SIRT1: resveratrol, fisetin, quercetin, and potent SRT2104, which combated psoriasis in humans. Now we have SIRT3 & SIRT5-activators to boost mitochondria. Will they work in humans? Refs👇 1/4 pubs.acs.org/doi/10.1021/ac…
The type 2 diabetes drug metformin is finally shown to slow aging! Aging needs to be called a “disease” so drugs like metformin can be prescribed before we get sick @US_FDA frontiersin.org/articles/10.33…
Gene variant of SIRT6 in human centenarians improves DNA break repair and gene silencing, matching what we discovered in yeast & mice, making this aging biology at least 1B years old
A treat to hang with one of my favorite authors, @sapinker 🤩 who taught me How The Mind Works and has a new book called Rationality. Just ordered a copy
Rationality: What It Is, Why It Seems Scarce, Why It Matters a.co/d/bA2tMv6
Mentioned @sapinker twice in Lifespan 🤩…
“The Harvard psychologist Steven Pinker put it this way in his book Enlightenment Now: The Case for Reason, Science, Humanism, and Progress: “Most people agree that life is better than death. Health is better than sickness…
