Longevity Research Newsletter May 2022

Welcome Vitalians to the inaugural issue of VitaDAO’s Monthly Longevity Research Newsletter!

Whether you are a longevity neophyte or a seasoned professor, we hope this will be an interesting and valuable resource to keep you up-to-date with the most important longevity research activity happening around the globe.

Why Longevity? Humans have long desired eternal life, with reports dating as far back as the first emperor of China, Qin Shi Huang (260–210), sending hoards of people out in search of the fabled Elixir of Life. But putting dewy-eyed dreams of immortality to one side, let’s consider that for many of the leading causes of death worldwide — cancer, heart disease, neurodegeneration — the biggest underlying risk is age. A school of thought has emerged proposing that, in addition to trying to tackle these diseases individually, we should also be investing in trying to understand the mechanisms which drive ageing itself in the hope that this knowledge could allow us to tackle all of these diseases simultaneously.

Why do we think ageing can be targeted? It is clear from looking at the animal kingdom that ageing rates are not universal — with lifespan ranges from a few years in small rodents to a staggering 200 years plus for bowhead whales. Some organisms such as sea hydras are even thought to be biologically immortal. But even comparing animals with similar sizes and metabolic rates such as mice and bats we observe a 10-fold difference in lifespan, with bats able to live over 30 years. Even among humans we observe disparities of over a decade in healthspan dependent upon postcode alone! Examples such as these provide evidence that ageing is influenced both by genetics and environment.

Experimental evidence? By mutating just a single gene in the microscopic nematode C. elegans, scientists were able to extend lifespan by around 10-fold. In mammals, a 50% increase in mice lifespan has also been achieved, which if translated to humans would mean some people living beyond 160 years old. Interventions such as calorie restriction and rapamycin dosing have also been shown to extend lifespan in numerous organisms.

Treating Ageing. Hitherto, ageing is not recognised by the FDA as a disease indication that can be treated. However the trail-blazing Targeting Aging with Metformin (TAME) trial, spearheaded by Dr. Nir Barzilai, hopes to achieve just that by conducting a 6-year study following over 3000 65–79 year olds to assess whether metformin can delay the onset and progression of age-related diseases https://www.afar.org/tame-trial

If successful, this will be a landmark moment in the history of medicine, however, conducting several year long trials in elderly populations for every new intervention is unfeasible and thus it will be imperative for more robust biomarkers of ageing to be developed so efficacies of interventions can be quantified much more quickly and cheaply.

VitaDAO’s Mission. Over the past few decades biogerontology research has gained significant traction in both academia and industry, however there is still a lack of funding for early stage research projects — VitaDAO aims to bridge this “valley of death” and accelerate R&D into the extension of both human healthspan and lifespan.

VitaDAO-funded Research Projects

This month we have seen two great projects receive approval for VitaDAO funding — with Jonathan An receiving up to 300k USD to tackle periodontitis (gum disease) with gero-science based treatments: https://snapshot.org/#/vote.vitadao.eth/proposal/0x8464713774628fa0af6262478f7c1ecccb0a3272cc72f6324183f598e9f29007 and ApoptoSENS receiving 253k USD to engineer Chimeric Antigen Receptor (CAR-NK) cells to precisely and safely eliminate senescent cells: https://snapshot.org/#/vote.vitadao.eth/proposal/0xcafd8183c8ac4990d99d90b3bd669de2c86376aa361c2384b12d578a49f686c0.

We will be keeping you up-to-date with each new project that gets funded as well as providing updates on existing projects when the data starts to roll in!

Longevity Literature Hot Picks

There is now such a plethora of longevity research being published on a daily basis that we would need a significant lifespan extension to read everything! So to help we have provided you with a selection of our hotpicks of the month — enjoy!

Somatic mutation rates scale with lifespan across mammals

https://www.nature.com/articles/s41586-022-04618-z

Somatic mutations are well known to cause cancer, but they also occur in normal tissue — for example skin cells. With age these mutant but morphologically normal cells multiply but no tumour develops. This happens in multiple tissues and the number of mutant cells dramatically increases with age. The Nature study shows that mutation rates grow linearly with age across species and the calculated mutation rates per year differ significantly between species. The organism mutation rate has a strong reverse correlation to lifespan.

Don’t forget to check out our interview with Alex Cagan — the first author of this paper — below!

Multi-omic rejuvenation of human cells by maturation phase transient reprogramming

https://elifesciences.org/articles/71624

Cellular reprogramming has definitely been a hot topic in the aging field and this new paper from Reik lab shows a new method to achieve this. The novel technique outperforms other reprogramming protocols. It was demonstrated to be highly effective in rejuvenating the epigenome of human skin cells from middle aged donors and turning the clock back 30 years according to a new transcriptomic clock.

FGF21 is required for protein restriction to extend lifespan and improve metabolic health in male mice

https://www.nature.com/articles/s41467-022-29499-8

Protein restricted diets have been shown to extend lifespan in numerous organisms — here Hill et al., show that beneficial health effects of protein restriction in mice are dependent on the metabolic hormone FGF21.

Early SRC activation skews cell fate from apoptosis to senescence

https://www.science.org/doi/full/10.1126/sciadv.abm0756

Upon severe genotoxic insult, cells undergo either apoptosis or senescence — here the authors show that inhibition of the kinase SRC can cause cells to preferentially apoptose, thus highlighting a potential therapeutic avenue to target senescent cells in aged or damaged tissues.

Cell senescence, rapamycin and hyperfunction theory of aging

https://pubmed.ncbi.nlm.nih.gov/35358003/

Prof. Mikhail Blagosklonny provides an interesting perspective that hyperfunctional signalling pathways, such as mTOR, can drive both cellular senescence and organismal ageing whilst arguing that the two are not dependent on each other.

Interview with Dr. Alex Cagan

After studying Anthropology at the University of Cambridge followed by a PhD in Evolutionary Genomics of Animal Domestication at the Max Planck institute, Dr. Cagan now works as a scientist at the Wellcome Sanger Institute — utilising the power of comparative genomics to better understand the processes of somatic evolution and how it relates to cancer and ageing. He also works as a scientific illustrator and is passionate about the combined power of art and science.

How do you think your latest paper on somatic mutations will impact the field of ageing research and what are the remaining questions?

In our paper we looked at cells in the intestinal crypt across 16 mammalian species and found a strong inverse correlation between somatic mutation rate and lifespan across. In other words the longer the lifespan of a species the slower the DNA mutation rate in the cells of that species, such that a mouse and a human end their lifespan with a similar number of somatic mutations in their intestinal cells. These findings are consistent with a role for somatic mutations in the aging process, something that has been theorized for decades. What the results don’t tell us is through what mechanisms, if any, somatic mutations are contributing to aging. This remains a fascinating open question. Our results also suggest that longer lived species than humans may have found ways to lower their mutation rate beyond our own. Studying these species and understanding how they achieve this, potentially through higher fidelity mechanisms of DNA repair, could be of great benefit.

What inspired you to enter longevity research?

Aging fascinates me because it is one of the fundamental biological processes that still remains relatively mysterious. As an evolutionary geneticist I am fascinated by exploring the relatively uncharted landscape of somatic evolution, the process by which mutations in the DNA occur and spread throughout the human body as we age. It’s long been known that this process causes cancer but due to technical limitations it has been challenging to study this process in normal tissues as we age. Now that genome sequencing methods have improved we are able to study this hitherto inaccessible process and are learning about how mutations in our cells radically alter the molecular landscape of our bodies as we age. I am excited to discover to what extent these processes may be contributing to a range of age-related diseases and potentially even aging itself.

How has the field changed since you started?

There has been an enormous surge in interest in this field since I started, both within academia as new technologies have been developed that enable us to quantify the aging process in new ways and from industry, as the potential of breakthroughs to improve the human healthspan is enormous.

Other than your own, what do you think have been the biggest/important discoveries in the field?

Because of the nature of aging as a multifactorial process there have been a multitude of important discoveries. As we have yet to fully understand which processes are the key drivers of aging it is challenging to assess their relative importance, they all contribute to our understanding. I would say that the discovery of epigenetic clocks, that telomere shortening and proteome turnover rates correlate with species lifespan and our growing understanding of cellular senescence are among the most important discoveries in the field.

What advice would you give to people currently working in longevity research?

I would say that it’s an incredibly exciting time to be working in this field and that given the multifactorial nature of aging a central challenge now is to quantify to what extent different molecular mechanisms contribute to specific phenotypic changes that occur during aging.

Which aspect of longevity research do you think requires more attention?

There are already species that have far longer lifespans than our own. More energy could be devoted to studying these species in order to understand the mechanisms by which they have extended their lifespans. In some senses evolution has already solved the problem of aging in these species and we would probably do well to try and learn from these solutions that are already sharing the planet with us.

Is ageing a disease?

Aging certainly raises the risk for a number of diseases. Whether or not we define aging itself as a disease I would consider largely a semantics issue, though with implications for how we think about our lives and how we fund aging research. I enjoy considering different perspectives on aging, whether it is something we should ‘accept’ or ‘conquer’ or ‘cure’. Such conversations remind me of Sophocles’ lines about humanity from Antigone ‘Numberless are the world’s wonders, but none more wonderful than man; …from every wind he has made himself secure — from all but one: In the late wind of death he cannot stand.” It is awe inspiring and humbling to think that there is a realistic prospect that aging itself could be overcome through human ingenuity. Though we are currently far from reaching this point I think it’s important that as a society we begin to have conversations about what the implications of this would mean.
