Summary
Epigenetic clocks like PhenoAge measure biological age more accurately than your birth certificate and predict disease risk years out. Smoking, exercise, diet, and socioeconomic factors all influence how fast your epigenetic clock ticks. Cellular reprogramming with Yamanaka factors may eventually reverse these aging markers entirely.
Key Points
- Epigenetic clocks like PhenoAge and GrimAge measure biological age more accurately than chronological age
- DNA methylation patterns show predictable changes with aging that correlate with disease risk
- Socioeconomic status, smoking, exercise, and diet all influence epigenetic age acceleration
- Sex differences and menopause significantly affect epigenetic aging trajectories
- Cellular reprogramming techniques using Yamanaka factors may potentially reverse aging markers
- Consumer epigenetic testing has variable reliability and should be interpreted cautiously
- Development plays a central role in aging processes, with early-life factors shaping later outcomes
Key Moments
Methylation Support Discussion
The problem is that this program gets completely rewritten with aging.
"The problem is that this program gets completely rewritten with aging. And we don't know exactly why, whether it's errors or whether it's just the program kind of having glitches along the way."
Epigenetic Aging: Clock
The conversation you're about to listen to features Dr. Morgan Levine, a founding principal investigator at Altos Labs, a new biotechnology company focused on the development of cellular rejuvenation technology.
"The problem is that this program gets completely rewritten with aging. And we don't know exactly why, whether it's errors or whether it's just the program kind of having glitches along the way."
Young Plasma Exchange Discussion
I think the other question though is, you know, cells also build up kind of these aggregates and other, you know, nasty kind of by-projects and accumulate what happens to them.
"People are doing this in the early 20th century. Basically, you can take two mice and connect their circulatory systems."
Methylation Support Discussion
I don't know what it's called, but... Yeah, surviving to the next.
"And it was interesting because the suppression of inflammation was the only thing that could predict going to the next age group or engineering. I don't know what it's called, but... Yeah, surviving to the next. Right."
Omega 3: Index
I don't know what it's called, but... Yeah, surviving to the next.
"And it was interesting because the suppression of inflammation was the only thing that could predict going to the next age group or engineering. I don't know what it's called, but... Yeah, surviving to the next. Right."
Epigenetic Aging: Clock
It was like decreasing a lot of the pro-inflammatory pathways. So, you know, at the level of methylation.
"Most people are predicted exactly the same age on their two tests, and so what I would say, so Elysium, as you mentioned, I'm no longer an advisor for them because I'm doing other stuff with Altos, but I was an advisor for them."
Caloric Restriction: Benefits
It makes you feel good. What's your favorite kind of exercise that you do?
"It makes you feel good. So for me, trying to maintain an active lifestyle as much as possible, I have a...you know, I sit at a desk a lot."
Epigenetic Aging: Clock
Some actually do worse with caloric restriction. The other thing that the reason I don't do caloric restriction personally is because there's studies, even in mice, that if you stop it, you lose the benefit.
"Any other... No, just thank you for having me. This was a really fun discussion. Well, thanks so much, Morgan. I'm excited. Yeah, absolutely. Yep. Perfect. Bye. Thank you so much to Dr. Levine for having this discussion with me."
