Anti-Aging: State of the Art

Copied from the response to another, similar, comment:

There are a number of publicly-traded longevity biotechnology companies. You could invest in Unity Biotechnology (NASDAQ:UBX) or Proteostasis Therapeutics (NASDAQ:PTI), for example. 

I also recommend the Longevity Market Cap newsletter.

Anti-Aging: State of the Art

If you're referring to median lifespan, we already know that many factors increase lifespan by up to 10-15 years in humans cumulatively: exercise, fasting, diet and so on. So it is highly likely that therapies (e.g. mTOR inhibitors) that potentially act through similar pathways will extend median lifespan. 

In terms of maximal lifespan, I'm not sure of the strength of those theoretical reasons in light of mechanisms of aging such as cellular senescence, which is known to strongly contribute to the aging phenotype in mice and humans and which can be removed in humans now (2020 study). 

Evolution is not optimizing for lifespan...only on gene transmission. So in general, I think arguments along the lines of 'as humans we are hitting our natural limit of lifespan' are poorly substantiated.

Some have calculated lifespan would be 2800-8900 years on average without aging.

Great - have you seen the existing Metaculus questions on anti-aging by Matthew Barnett and others? 

Anti-Aging: State of the Art

Hi bardstale,

'Deregulated nutrient sensing' is one of the 9 hallmarks of aging covered in the article, and includes insulin signaling (IGF-1, etc) - that is, insulin signaling pathways. 

Dietary protocols such as the fasting-mimicking diet (FMD) and ketogenic diets attenuate IGF-1 which is potentially beneficial for longevity. However, lifestyle protocols were not the focus of this article, since ultimately, lifestyle interventions alone are not likely sufficient to extend maximal lifespan beyond 125 years. Another way to phrase this, is that these diets are 'anti-aging' insofar as they slow the rate of aging, but not reverse it to a level that could potentially be achieved with therapies.

The goal of anti-aging research is to provide new therapies that can allow us to live much longer than is available with the best approaches today (diet/exercise/meditation/low stress etc.).

Hi icemtel, 

There are a number of publicly-traded longevity biotechnology companies. You could invest in Unity Biotechnology (NASDAQ:UBX) or Proteostasis Therapeutics (NASDAQ:PTI), for example. 

I also recommend the Longevity Market Cap newsletter.

For larger investments, you could also look into longevity biotech VC's such as Apollo Health Ventures.

Anti-Aging: State of the Art

I did not include the Tel Aviv/HBOT study since it is not considered a promising approach to anti-aging by most researchers in the field. The conclusions of the study are potentially misleading, due to the highly improbable senolytic effect of oxygen therapy.

In my recent interview with Dr Aubrey de Grey, I asked him about this same study (timestamp: 40:30), and he said that it was enormously over-hyped. 

I encourage you to read this article, which explains the media circus around the study, and critiques the science:

Thank you very much, I appreciate it. This is only a short introduction to the field, and I plan to write several follow-up articles in the near future to create a larger sequence (covering: aging and COVID-19, the ethical arguments for/against anti-aging, aging and cancer, and more anti-aging therapy approaches). 

Anti-Aging: State of the Art

Thanks for the tip - just added 'become a researcher' and 'work for a longevity biotech company' as additional ways to help the field.

Thank-you for the kind words! Stay tuned for more articles like this one coming soon.
