October Longevity Research Newsletter

October 13, 2022
Maria Marinova & Rhys Anderson


Welcome back to VitaDAO’s monthly longevity research newsletter!

Some species in the animal kingdom live extraordinarily long lives. They seem to be somehow protected from all the damage that we would expect to accumulate in aged tissues. Many are very large, like bowhead whales, and there is an established correlation between mass and lifespan, often attributed to slower metabolism. There are also animals like the naked mole rat, which live many times the life of a rodent of the same size with no increased risk of disease or decline of physiological function. We have a lot to learn from such species and Prof. Vera Gorbunova is doing just that - her lab focuses on understanding the underlying mechanisms of aging and how they differ between long-lived mammals and humans. We interviewed her for this month’s issue, so make sure you don’t miss this! (and if you just can’t wait, it can be found towards the bottom of this page!)

Longevity Literature Hot Picks

As so many great longevity papers are being published every month, we’ve decided to keep our newly introduced Further Reading section at the end of the newsletter! But first, here are our hotpicks of the month:

Sex- and age-dependent genetics of longevity in a heterogeneous mouse population

This substantial body of work, done on the largest-ever mouse longevity study unravels the distinct genetic determinants of male vs female longevity. The group has compiled their data with other sources to produce an interactive research tool, which is quite fun to play around with:

Brown-fat-mediated tumour suppression by cold-altered global metabolism

Cancer cells are known to utilise glycolysis to provide cellular energy - a process reliant upon glucose uptake. Non-shivering thermogenesis of adipose tissues also requires glucose uptake. Interestingly, Seki et al., show that cold exposure can lead to a non-shivering thermogenesis-induced decrease in blood glucose levels which can attenuate tumour growth!

Pan-cancer analyses reveal cancer-type-specific fungal ecologies and bacteriome interactions

A pan-cancer mycobiome analysis reveals fungal involvement in gastrointestinal and lung tumors

For years research has implicated a role for bacteria in cancer - now two papers published in Cell provide extensive evidence that fungi are also found in numerous cancers and can even be associated with different prognoses. Certain fungi and bacteria were even found to often co-exist in some cancer types. This adds an additional level of complexity to our understanding of cancer, and could provide new markers for diagnostic and prognostic testing.

Insulin signaling in the long-lived reproductive caste of ants

There is a trade-off between reproduction and lifespan in most organisms, but the queen ant is an exception. When a caste ant switches to a reproductive status of a pseudo-queen, her lifespan is extended 5x. During this switch, genes expression patters of insulin, MAPK, AKT is altered, consistent with the observed longer life.

SIRT3 deficiency decreases oxidative metabolism capacity but increases lifespan in male mice under caloric restriction

Contrary to previous hypotheses that the mitochondrial SIRT3 is responsible for caloric restriction (CR) mediated lifespan extension, this study shows that deletion of SIRT3 actually extends the life of mice under CR conditions. This points to SIRT3 being dispensable for CR induced lifespan extension but it is required for aerobic capacity and oxidative metabolism.

Ketogenic diet prevents chronic sleep deprivation-induced Alzheimer’s disease by inhibiting iron dyshomeostasis and promoting repair via Sirt1/Nrf2 pathway

An interesting interplay between sleep diet and Alzheimer’s has been described. Ketogenic diet seemed to be preventative of cognitive deficiency, amyloid deposition and hyperphosphorylated tau induced by chronic sleep deprivation by inhibiting ferroptosis and alleviating oxidative stress. 

Is “cellular senescence” a misnomer?

David Gems and Carina Kern argue that considering cellular senescence has been shown to play roles in healthy physiological processes such as acute wound healing and embryogenesis, perhaps the word ‘senescent’ is a misnomer as the dictionary definition implies that something is old. Instead they propose the term should be replaced with one more descriptive of the phenotype - “remodelling activation” - which would consequently replace SASP with RASP. Whilst it’s unlikely that the word will change any time soon (historically used terms have sticking power) it’s an important idea to keep in mind when thinking about what exactly a senescent cell is.

Rapamycin treatment during development extends life span and health span of male mice and Daphnia magna

Another study convincingly shows how tightly connected development and aging are. Only 45 days of rapamycin treatment during early development (right after birth) were sufficient to increase lifespan by 10% in male mice. The cost of this was smaller size and slowed down development. 

Drugs, clocks and exercise in ageing: hype and hope, fact and fiction

This review takes a broad look at the field and compares the effects of pharmacological vs non-pharmacological interventions and the accuracy and predictive power of functional measurements vs aging clocks. Roadblocks in the advancement of the field and potential future strategies are also discussed.

Aging and cancer epigenetics: Where do the paths fork?

There is a clear association between aging and cancer on molecular and eidemiological level but can this also be explained via epigenetic mechanisms? While there are considerable differences between the two processes, epigenetic clocks could be key to unravel the intricacies of this relationship, especially if integrated with genetic evidence of DNA damage.

Interview with Professor Vera Gorbunova

Prof. Vera Gorbunova is a Professor of Biology at the University of Rochester and a director of the Rochester Aging Research Center. Her research is centred around aging, cancer and genome stability. Her lab aims to understand the basic mechanisms underlying these processes by studying multiple model organisms, especially long-lived mammals. 

What inspired you to enter longevity research?

This is the most fascinating problem in biology and medicine… How could I work on anything else?
Longevity research addresses a fundamental problem of biology and has relevance to every living human.

Which of the current theories of ageing do you think are the most convincing?

I find the damage accumulation theory the most convincing. However, the nature of this “damage” is a subject of debate. Most likely, this is a combination of DNA damage, mutations and epigenetic dysregulation.

How has the field changed since you started?

I witnessed tremendous progress. We now have the tools we did not have before. Genomes of various species, various other omics tools became widely available and used in everyday research. Conserved pathways of aging had been identified in model organisms.

What mistakes do you think the longevity field has made?

Too much focus on short-lived model organisms. These organisms are helpful to identify conserved aging pathways, but they are not suitable to find longevity adaptations that evolved in long-lived species.

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

Do more bold and out of the box things. We need novel approaches and new research models. When studying long-lived organisms, do not just compare young to old. Obviously, the long-lived organisms age slower. What is most important is to find the mechanisms that make them age slower.

Is ageing a disease?

From the evolutionary standpoint aging is not a disease. However, we have to approach it as a disease to develop treatments and interventions.

You have done research across the animal kingdom. How do long-lived animals benefit longevity research? What are the most promising organisms to study that are currently underexplored?

Long-lived animals are essential for longevity research as they hold the clues for long lifespan. I am particularly interested in long-lived mammals because they are phylogenetically closer to people and the discoveries would be more translatable. There are many long-lived mammals and each may have evolved unique longevity mechanisms. That is why it is important to study all of them. My group works on naked mole rats, bats, bowhead whales and many other mammalian species. 

What are the most interesting insights from naked mole rat studies and what are potential ways to translate them?

There were many interesting discoveries made on naked mole rats. The most interesting ones come when researchers look at novel mechanisms not merely testing the same pathways that were shown to be important in short-lived species. Here I can name our discovery of abundant hyaluronic acid and unique ribosomal structure with split 28S rRNA that results in highly accurate protein synthesis.

Could you explain hyaluronic acid anti-tumour and pro-longevity effects you have observed, and do you see this as a potential intervention in humans?

Naked mole rat tissues are saturated with hyaluronic acid of very high molecular weight (HMW-HA). Such hyaluronic acid has antiproliferative properties and arrests proliferation of premalignant cells leading to lower cancer incidence. HMW-HA is also a potent anti-inflammatory molecule reducing inflammation in the body and through this having an anti-aging effect.
