For its second expert panel, the U.S. Transhumanist Party invited Bill Andrews, Aubrey de Grey, Ira Pastor, and Ilia Stambler to discuss life extension and the quest to reverse biological aging through science and technology.

This two-hour panel discussion, moderated by Chairman Gennady Stolyarov II, took place on Saturday, February 18, 2017, at 10 a.m. U.S. Pacific Time. In this interactive venue, many opportunities for fresh discourse arose on the possibility of achieving dramatically greater longevity within our lifetimes. The substance of the discussion begins at 4:25 in the recording.

Questions the panelists considered include the following:

(i) How would you characterize the current state of efforts to reverse senescence / lengthen human lifespans?
(ii) How does progress in the areas of research you have delved into compare to your expectations approximately 10 to 15 years ago?
(iii) What are the most significant challenges and obstacles that you perceive to exist in the way of achieving serious reversal of biological aging?
(iv) What key technologies and methods of delivering treatments to patients would need to be developed in order for longevity escape velocity to be affordably achieved society-wide?
(v) What political reforms and societal / attitudinal changes would you advocate to accelerate the arrival of effective treatments to reverse biological aging and lengthen lifespans?
(vi) Are you concerned about any current political trends and how they might affect the progress of research into combating biological aging?
(vii) What can laypersons who are sympathetic to your goals do in order to hasten their realization? How can the effort to defeat aging become as popular and widely supported as efforts to defeat cancer and ALS are today?
(viii) What lessons can the history of anti-aging research offer to those who seek to advocate and help achieve effective scientific breakthroughs in this area in the coming years and decades?

UNITY Biotechnology Raises $116M for Senescent Cell Clearance Development – Article by Reason

UNITY Biotechnology Raises $116M for Senescent Cell Clearance Development – Article by Reason

The New Renaissance HatReason
******************************

The whispers of late have had it that UNITY Biotechnology was out raising a large round of venture funding, and their latest press release shows that this was indeed the case. The company, as you might recall, is arguably the more mainstream of the current batch of startups targeting the clearance of senescent cells as a rejuvenation therapy. The others include Oisin Biotechnologies, SIWA Therapeutics, and Everon Biosciences, all with different technical approaches to the challenge. UNITY Biotechnology is characterized by a set of high profile relationships with noted laboratories, venture groups, and big names in the field, and, based on the deals they are doing, appear to be focused on building a fairly standard drug development pipeline: repurposing of apoptosis-inducing drug candidates from the cancer research community to clear senescent cells, something that is being demonstrated with various drug classes by a range of research groups of late. Senescent cells are primed to apoptosis, so a nudge in that direction provided to all cells in the body will have little to no effect on normal cells, but tip a fair proportion of senescent cells into self-destruction. Thus the UNITY Biotechnology principals might be said to be following the standard playbook to build the profile of a hot new drug company chasing a hot new opportunity, and clearly they are doing it fairly well so far.

UNITY Biotechnology Announces $116 Million Series B Financing

Quote:

UNITY Biotechnology, Inc. (“UNITY”), a privately held biotechnology company creating therapeutics that prevent, halt, or reverse numerous diseases of aging, today announced the closing of a $116 million Series B financing. The UNITY Series B financing ranks among the largest private financings in biotech history and features new investments from longtime life science investors ARCH Venture Partners, Baillie Gifford, Fidelity Management and Research Company, Partner Fund Management, and Venrock. Other investors include Bezos Expeditions (the investment vehicle of Jeff Bezos) and existing investors WuXi PharmaTech and Mayo Clinic Ventures. Proceeds from this financing will be used to expand ongoing research programs in cellular senescence and advance the first preclinical programs into human trials.

The financing announcement follows the publication of research that further demonstrates the central role of senescent cells in disease. The paper, written by UNITY co-founders Judith Campisi and Jan van Deursen and published today, describes the central role of senescent cells in atherosclerotic disease and demonstrates that the selective elimination of senescent cells holds the promise of treating atherosclerosis in humans. In animal models of both early and late disease, the authors show that selective elimination of senescent cells inhibits the growth of atherosclerotic plaque, reduces inflammation, and alters the structural characteristics of plaque such that higher-risk “unstable” lesions take on the structural features of lower-risk “stable” lesions. “This newly published work adds to the growing body of evidence supporting the role of cellular senescence in aging and demonstrates that the selective elimination of senescent cells is a promising therapeutic paradigm to treat diseases of aging and extend healthspan. We believe that we have line of sight to slow, halt, or even reverse numerous diseases of aging, and we look forward to starting clinical trials with our first drug candidates in the near future.”

So this, I think, bodes very well for the next few years of rejuvenation research. It indicates that at least some of the biotechnology venture community understands the likely true size of the market for rejuvenation therapies, meaning every human being much over the age of 30. It also demonstrates that there is a lot of for-profit money out there for people with credible paths to therapies to treat the causes of aging. It remains frustrating, of course, that it is very challenging to raise sufficient non-profit funds to push existing research in progress to the point at which companies can launch. This is a problem throughout the medical research and development community, but it is especially pronrounced when it comes to aging. The SENS view of damage repair, which has long incorporated senescent cell clearance, is an even tinier and harder sell within the aging research portfolio – but one has to hope that funding events like this will go some way to turn that around.

From the perspective of being an investor in Oisin Biotechnologies, I have to say that this large and very visible flag planted out there by the UNITY team is very welcome. The Oisin team should be able to write their own ticket for their next round of fundraising, given that the gene therapy technology they are working on has every appearance of being a superior option in comparison to the use of apoptosis-inducing drugs: more powerful, more configurable, and more adaptable. When you are competing in a new marketplace, there is no such thing as too much validation. The existence of well-regarded, well-funded competitors is just about the best sort of validation possible. Well-funded competitors who put out peer-reviewed studies on a regular basis to show that the high-level approach you and they are both taking works really well is just icing on the cake. Everyone should have it so easy. So let the games commence! Competition always drives faster progress. Whether or not I had skin in this game, it would still be exciting news. The development of rejuvenation therapies is a game in which we all win together, when new treatments come to the clinic, or we all lose together, because that doesn’t happen fast enough. We can and should all of us be cheering on all of the competitors in this race. The quality and availability of the outcome is all that really matters in the long term. Money comes and goes, but life and health is something to be taken much more seriously.

Now with all of that said, one interesting item to ponder in connection to this round of funding for UNITY is the degree to which it reflects the prospects for cancer therapies rather than the prospects for rejuvenation in the eyes of the funding organizations. In other words, am I being overly optimistic in reading this as a greater understanding of the potential for rejuvenation research in the eyes of the venture community? It might be the case that the portions of the venture community involved here understand the market for working cancer drugs pretty well, and consider that worth investing in, with the possibility of human rejuvenation as an added bonus, but not one that is valued appropriately in their minds. Consider that UNITY Biotechnology has partnered with a noted cancer therapeutics company, and that the use of drugs to inducing apoptosis is a fairly well established approach to building cancer treatments. That is in fact why there even exists a range of apoptosis-inducing drugs and drug candidates for those interested in building senescent cell clearance therapies to pick through. Further, the presence of large numbers of senescent cells does in fact drive cancer, and modulating their effects (or removing them) to temper cancer progress is a topic under exploration in the cancer research community. So a wager on a new vision, or a wager on the present market? It is something to think about.

An Example of the Glaring Lack of Ambition in Aging Research – Post by Reason

An Example of the Glaring Lack of Ambition in Aging Research – Post by Reason

The New Renaissance HatReason
******************************

The mainstream of aging research, at least in public, is characterized by a profound lack of ambition when it comes to treating aging as a medical condition. Researchers talk about slightly altering the trajectory of aging as though that is the absolute most that is possible, the summit of the mountain, and are in many cases ambivalent when it comes to advocating for even that minimal goal. It is this state of affairs that drove Aubrey de Grey and others into taking up advocacy and research, given that there are clear paths ahead to rejuvenation, not just a slight slowing of aging, but halting and reversing the causes of aging. Arguably embracing rejuvenation research programs would in addition cost less and take a much shorter span of time to produce results, since these programs are far more comprehensively mapped out than are efforts to produce drugs to alter the complex operations of metabolism so as to slightly slow the pace at which aging progresses. It is most frustrating to live in a world in which this possibility exists, yet is still a minority concern in the research community. This article is an example of the problem, in which an eminent researcher in the field takes a look at a few recently published books on aging research, and along the way reveals much about his own views on aging as an aspect of the human condition that needs little in the way of a solution. It is a terrible thing that people of this ilk are running the institutes and the funding bodies: this is a field crying out for disruption and revolution in the name of faster progress towards an end to aging.

How can we overcome our niggling suspicion that there is something dubious, if not outright wrong, about wanting to live longer, healthier lives? And how might we pursue longer lives without at the same time falling prey to quasiscientific hype announcing imminent breakthroughs? In order to understand why aging is changing, and what this means for our futures, we need to learn more about the aging process itself. As a biologist who specializes in aging, I have spent more than four decades on a quest to do exactly this. Not only have I asked why aging should occur at all (my answer is encapsulated in a concept called disposability theory), but I have also sought to understand the fastest-growing segment of the population – those aged 85 and above. The challenges inherent in understanding and tackling the many dimensions of aging are reflected in a clutch of new books on the topic. Are these books worth reading? Yes and no. They take on questions like: Can we expect increases in human longevity to continue? Can we speed them up? And, on the personal level, what can we do to make our own lives longer and healthier? If nothing else, these books and their varied approaches reveal how little we actually know.

To find out more about factors that can influence our individual health trajectories across ever-lengthening lives, my colleagues and I began, in 2006, the remarkable adventure of the still ongoing Newcastle 85+ Study, an extremely detailed investigation of the complex medical, biological, and social factors that can affect a person’s journey into the outer reaches of longevity. For each individual, we determined whether they had any of 18 age-related conditions (e.g., arthritis, heart disease, and so on). Sadly, not one of our 85-year-olds was free of such illnesses. Indeed, three quarters of them had four or more diseases simultaneously. Yet, when asked to self-rate their health, an astonishing 78 percent – nearly four out of five – responded “good,” “very good,” or “excellent.” This was not what we had expected. The fact that these individuals had so many age-related illnesses fit, of course, with the popular perception of the very old as sadly compromised. But the corollary to this perception – that in advanced old age life becomes a burden, both to the individuals themselves and to others – was completely overturned. Here were hundreds of old people, of all social classes and backgrounds, enjoying life to the fullest, and apparently not oppressed by their many ailments.

As for my stake in the enterprise, I began investigating aging when I was in my early 20s – well before I had any sense of my own body aging. Quite simply, I was curious. What is this mysterious process, and why does it occur? Everything else in biology seems to be about making things work as well as they can, so how is it that aging destroys us? Now that I am growing older myself, my research helps me understand my own body and reinforces the drive to live healthily – to eat lightly and take exercise – though not at the cost of eliminating life’s pleasures. For all that I have learned about aging, my curiosity remains unabated. Indeed, it has grown stronger, partly because as science discovers more about the process, it reveals that there is ever more to learn, ever greater complexity to unravel, and partly because I am now my own subject: through new physical and psychological experiences in myself, I learn more about what older age is really like. I know all too well that the next phase of my life will bring unwelcome changes, and of course it must end badly. But the participants of the Newcastle 85+ Study have shown me that the journey will not be without interest.

An Interview with Kelsey Moody of Ichor Therapeutics, Bringing a SENS Therapy for Macular Degeneration to the Clinic – Article by Reason

An Interview with Kelsey Moody of Ichor Therapeutics, Bringing a SENS Therapy for Macular Degeneration to the Clinic – Article by Reason

The New Renaissance HatReason
******************************

As I mentioned last week, earlier this year Fight Aging! invested a modest amount in the Ichor Therapeutics initiative to develop a treatment for macular degeneration, joining a number of other amateur and professional investors in helping to get this venture started. The approach taken here is based on the results of research carried out at the Methuselah Foundation and SENS Research Foundation over much of the past decade, funded by philanthropists and the support of our community of longevity science enthusiasts. This is how we succeed in building the future: medical science in the laboratory leads to medical development in startup companies, each new stage bringing treatments capable of repairing specific forms of age-related molecular damage that much closer to the clinic.

Ichor Therapeutics is one of a growing number of success stories to emerge from the SENS rejuvenation research community. Young scientists, advocates, and donors involved in earlier projects – years ago now – have gone on to build their own ventures, while retaining an interest in stepping up to do something meaningful to help bring an end to aging. Back in 2010, Kelsey Moody worked on the LysoSENS project to find ways to break down damaging metabolic waste in old tissues; fast-forward six years, and he is the now the CEO of a successful small biotechnology company with a great team, taking that very same technology and putting it to good use. I recently had the chance to ask Kelsey a few questions about the future of SENS rejuvenation research, as well as how the Ichor scientists intend to construct a new class of therapy for macular degeneration, one based on removing one of the root causes of the condition.

Quote:

Who are the people behind Ichor Therapeutics? How did you meet and decide that this was the thing to do? Why macular degeneration as a target?

People have always been the focus of Ichor. Since day one we have worked to create a positive environment that cultivates a product-oriented research focus and emphasizes autonomy and personal accountability for work. As a result, ambitious self-starters tend to find their way to Ichor and remain here. However, we recognized early on that just filling a lab with a bunch of blue-eyed bushy tailed young up-and-comers is not sufficient to develop a robust, mature, translational pipeline. We have augmented our team with a number of critical staff members who are seasoned pharma operators, including our Quality Assurance Director and General Counsel.

Age-related macular degeneration (AMD) was chosen as a target because we believe it is the closest SENS therapy to the clinic. While we obviously have an interest in providing cures for the patients suffering from AMD and are attracted to the large market opportunities such a treatment could bring, our broader interest is in validating the entire SENS paradigm. We believe that Aubrey de Grey continues to receive excessive criticism because nothing spun out of SENS has ever made it into a legitimate pre-clinical pipeline, much less to the bedside. However, this does not mean he is wrong. Our goal is to be the first group to bring a SENS inspired therapy into the clinic and in doing so, silence critics and generate new energy and capital for this cause.

I understand there’s a lengthy origin story for the approach you are taking to treat AMD; it’d be great to hear some of it.

Our approach to treating AMD is based on the hypothesis that cellular junk that accumulates over the lifespan significantly contributes to the onset and progression of AMD. Our goal is to periodically reduce the burden of the junk so it never accumulates to levels sufficient to induce pathology. The strategy to accomplish this calls for the identification of enzymes that can break down the junk in a physiological setting, and the engineering of these enzymes such that they can break down the target in the correct organelle of the correct cell without appreciable collateral damage to healthy cells or tissue.

Methuselah Foundation and SENS Research Foundation did excellent work in establishing this program nearly a decade ago. They successfully identified a number of candidate enzymes that could break down the molecular junk, but reported that the targeting systems evaluated failed to deliver these enzymes to the appropriate organelles and cells. My group reevaluated these findings, and discovered that these findings were flawed. The delivery failure could be entirely attributed to a subtle, yet highly significant difference between how the target cells behave outside of the body as compared to inside the body. It turned out that the approach was in fact valid, it was the cell based assay that had been used that was flawed. This discovery was striking enough that SENS Research Foundation provided Ichor with funding and a material and technology transfer agreement to reassess the technology, and over $700,000 in directed program investments and grants have been received in the last year or two.

You recently completed a round of funding for the AMD work; what is the plan for the next year or so?

The new funds will allow us to develop a portfolio of enzyme therapy candidates to treat AMD. We will obtain critical data necessary to secure follow-on investment including in vitro studies (cell culture studies to confirm mechanism of action and cytotoxicity) and pivotal proof-of-concept in vivo studies, such as toxicity, PK/PD (how long the enzyme stays in the body and where), and efficacy. We will also be restructuring the company (reincorporating an IP holding company in Delaware, ensuring all contracts are up to date and audited) and ensuring our IP position is on solid footing (licensing in several related patents from existing collaborators, and filing several provisional patents from our intramural work). Collectively, we believe these efforts will position us to obtain series A for investigational new drug (IND) enabling pre-clinical studies.

You’ve been involved in the rejuvenation research community for quite some time now. What is your take on the bigger picture of SENS and the goal of ending aging?

This is a loaded question. What I can say is that the medical establishment has made great progress in the treatment of infectious disease through the development of antibiotics, vaccines, and hygiene programs. However, similar progress has not been realized for the diseases of old age, despite exorbitant expenditures. I have chosen to work in this space because I think a different approach is necessary, and it is here that I believe my companies and I can be the most impactful. I think SENS provides a good framework within which to ask and answer questions.

What do you see as the best approach to getting nascent SENS technologies like this one out of the laboratory and into the clinic?

We need more people who fully understand, in a highly detailed way, what a real translational path looks like. To take on projects like this, being a good scientist is not enough. We need people who can speak business, science, medicine, and legal, and apply these diverse disciplines to a well articulated, focused product or problem. There is no shortage of people who partially understand some of these, but the details are not somewhat important – they are all that matter for success in this space.

Another area is for investors. Some of the projects that come across my desk for review are truly abysmal, yet I have seen projects that are clearly elaborate hoaxes or outright scams (to anyone who has stepped foot in a laboratory) get funded to the tune of hundreds of thousands of dollars or more. While it is perfectly reasonable for high net worth individuals to gamble on moon shots in the anti-aging space (and I am ever grateful for the investors who have taken such a gamble on us) even aggressive development strategies should have some basis in reality. This is especially true as more and more high tech and internet investors move into the space.

If this works stupendously well, what comes next for Ichor Therapeutics?

I really want to get back into stem-cell research, but I basically need a blank check and a strong knowledge of the regulatory path to clinic before I feel comfortable moving into the space. A successful AMD exit would accomplish both of these goals, and position us to pivot to cell-based therapies.

Aubrey de Grey at the Launching Longevity Panel, and Announcing Acceptance of the First Paper to be Published on MitoSENS Research – Article by Reason

The New Renaissance HatReason
******************************

Today I’ll direct your attention to a couple of videos, thematically linked by the presence of Aubrey de Grey, cofounder of the SENS Research Foundation and tireless advocate for progress towards working rejuvenation therapies. For the first of the videos, de Grey recently took part in a panel discussion involving representatives of the biotechnology industry, the research establishment, and venture capital community, with the topic being the coming development of a new industry that will develop therapies to extend healthy life and turn back aging. That industry has barely started to form its earliest and smallest stage today, as the first lines of rejuvenation research reach the point of commercial viability. There are a few startups and a lot of deep pockets yet to be convinced that this is going somewhere – though the commentary in the panel is encouraged, considering those involved.

The recent Rejuvenation Biotechnology 2016 conference hosted by the SENS Research Foundation was more along the same lines, focused on creating a foundation for the near future industry that will build and provide rejuvenation therapies. The purpose of the conference series is to help smooth the way for these treatments to move rapidly from the laboratory to the clinic, to build the necessary relationships, manage expectations, and pull in the additional support needed to make best possible progress. The conference was livestreamed over the past couple of days, and at one point Aubrey de Grey announced the just-then-and-there acceptance of the first scientific publication for the MitoSENS team at the SENS Research Foundation. They are presently in the lead, at the cutting edge, among the few groups working on the project of copying mitochondrial genes into the cell nucleus to protect them from the damage of aging. Ultimately, copying all thirteen genes should completely remove the contribution of mitochondrial damage to degenerative aging, as mitochondria will no longer become dysfunctional as their local DNA is damaged. They will get the proteins they need from the cell nucleus instead. It is a worthy project, and it is always welcome to see progress on this front.

Launching Longevity: Funding the Fountain of Youth

 

Can technology make human longevity a reality? As the pace of discovery accelerates, scientists and entrepreneurs are closing in on the Fountain of Youth. Disrupting the aging process by hacking the code of life, promises better health and longer maximum lifespans. With many layers of complexity from science to ethics, there are still skeptics placing odds against human longevity. Venture capitalists are betting on success; putting big money on the table to fund longevity startups. Google/Alphabet and drugmaker AbbVie have invested $1.5 billion on Calico, while Human Longevity Inc. recently raised $220 million from their Series B funding round. Complementing traditional venture investment, VCs like Peter Thiel and Joon Yun have established foundations and prizes to accelerate the end of aging. Why are VCs suddenly investing heavily in longevity startups? Will extended lifespan be a privilege of the wealthy or will the benefits be accessible to all? How long before these well-funded startups bring viable products to market?

 

Aubrey de Grey Announces Progress in MitoSENS

 

Ok everybody, before I introduce the next session I just wanted to make a very small, brief, but very welcome announcement. Literally half an hour ago we received some extremely good scientific news. Those of you who have been following SENS research since before the SENS Research Foundation itself even existed will know that, about a decade ago, the very first project, the very first research program that we were able to initiate – with the help of, especially, the initial donation of Peter Thiel – was to make mitochondrial mutations harmless by essentially putting backup copies of the mitochondrial DNA into the nuclear genome, modified in such way of course that the encoded proteins would be colocated back into the mitochondria to do their job. This is an idea that was first put forward more than 30 years ago, but it is an idea that despite quite a bit of initial effort, nobody was able to make work. When I first came across this concept, in fact I’d thought of it myself, it’s a pretty obvious idea really, I came to the conclusion that a lot of the despair and despondency and pessimism about this approach was premature, and that it was worth having another go, and so that was the very first project we decided to fund.

Suffice to say that it has not been quite as easy as I was hoping to make progress in that space, but progress has now been made, step by step, over the past several years, with the help especially of the absolutely amazing team we have at the research center, who work on this, headed by Matthew O’Connor. Amutha Boominathan is the number two on the team, and is absolutely indispensable, I’ve no idea where we’d be without her. So, what’s happened half an hour ago is that for the very first time in the entire history of this project, we have got far enough to have a paper accepted in a very nice journal, Nucleic Acids Research, which reports on our progress in this area. The headline result in this paper is that we are the first team ever to get two of the proteins encoded by genes in the mitochondrial DNA simultaneously functioning in the same cell line, and of course – two is equivalent to infinity for mathematicians, you know that, right? – this is extremely heartening news, and I just wanted to let you all know, thank you.

Towards a Greater Knowledge of Mitochondrial DNA Damage in Aging – Article by Reason

Towards a Greater Knowledge of Mitochondrial DNA Damage in Aging – Article by Reason

The New Renaissance HatReason
******************************

Today I’ll point out a very readable scientific commentary on mutations in mitochondrial DNA (mtDNA) and the importance of understanding how these mutations spread within cells. This is a topic of some interest within the field of aging research, as mitochondrial damage and loss of function is very clearly important in the aging process. Mitochondria are, among many other things, the power plants of the cell. They are the evolved descendants of symbiotic bacteria, now fully integrated into our biology, and their primary function is to produce chemical energy store molecules, adenosine triphosphate (ATP), that are used to power cellular operations. Hundreds of mitochondria swarm in every cell, destroyed by quality control processes when damaged, and dividing to make up the numbers. They also tend to promiscuously swap component parts among one another, and sometimes fuse together.

Being the descendants of bacteria, mitochondria have their own DNA, distinct from the nuclear DNA that resides in the cell nucleus. This is a tiny remnant of the original, but a very important remnant, as it encodes a number of proteins that are necessary for the correct operation of the primary method of generating ATP. DNA in cells is constantly damaged by haphazard chemical reactions, and equally it is constantly repaired by a range of very efficient mechanisms. Unfortunately mitochondrial DNA isn’t as robustly defended as nuclear DNA. Equally unfortunately, some forms of mutation, such as deletions, seem able to rapidly spread throughout the mitochondrial population of a single cell, even as they make mitochondria malfunction. This means that over time a growing number of cells become overtaken by malfunctioning mitochondria and fall into a state of dysfunction in which they pollute surrounding tissues with reactive molecules. This can, for example, increase the level of oxidized lipids present in the bloodstream, which speeds up the development of atherosclerosis, a leading cause of death at the present time.

The question of how exactly some specific mutations overtake a mitochondrial population so rapidly is still an open one. There is no shortage of sensible theories, for example that it allows mitochondria to replicate more rapidly, or gives them some greater resistance to the processes of quality control that normally cull older, damaged mitochondria. The definitive proof for any one theory has yet to be established, however. In one sense it doesn’t actually matter all that much: there are ways to address this problem through medical technology that don’t require any understanding of how the damage spreads. The SENS Research Foundation, for example, advocates the path of copying mitochondrial genes into the cell nucleus, a gene therapy known as allotopic expression. For so long as the backup genes are generating proteins, and those proteins make it back to the mitochondria, the state of the DNA inside mitochondria doesn’t matter all that much. Everything should still work, and the present contribution of mitochondrial DNA damage to aging and age-related disease would be eliminated. At the present time there are thirteen genes to copy, a couple of which are in commercial development for therapies unrelated to aging, another couple were just this year demonstrated in the lab, and the rest are yet to be done.

Still, the commentary linked below is most interesting if you’d like to know more about the questions surrounding the issue of mitochondrial DNA damage and how it spreads. This is, as noted, a core issue in the aging process. The authors report on recent research on deletion mutations that might sway the debate on how these mutations overtake mitochondrial populations so effectively.

Expanding Our Understanding of mtDNA Deletions

A challenge of mtDNA genetics is the multi-copy nature of the mitochondrial genome in individual cells, such that both normal and mutant mtDNA molecules, including selfish genomes with no advantage for cellular fitness, coexist in a state known as “heteroplasmy.” mtDNA deletions are functionally recessive; high levels of heteroplasmy (more than 60%) are required before a biochemical phenotype appears. In human tissues, we also see a mosaic of cells with respiratory chain deficiency related to different levels of mtDNA deletion. Interestingly, cells with high levels of mtDNA deletions in muscle biopsies show evidence of mitochondrial proliferation, a compensatory mechanism likely triggered by mitochondrial dysfunction. In such circumstances, deleted mtDNA molecules in a given cell will have originated clonally from a single mutant genome. This process is therefore termed “clonal expansion.”

The accumulation of high levels of mtDNA deletions is challenging to explain, especially given that mitophagy should provide quality control to eliminate dysfunctional mitochondria. Studies in human tissues do not allow experimental manipulation, but large-scale mtDNA deletion models in C. elegans have proved to be helpful, showing some conserved characteristics that match the situation in humans, as well as some divergences. Researchers have used a C. elegans strain with a heteroplasmic mtDNA deletion to demonstrate the importance of the mitochondrial unfolded protein response (UPRmt) in allowing clonal expansion of mutant mtDNAs to high heteroplasmy levels. They demonstrate that wild-type mtDNA copy number is tightly regulated, and that the mutant mtDNA molecules hijack endogenous pathways to drive their own replication.

The data suggests that the expansion of mtDNA deletions involves nuclear signaling to upregulate the UPRmt and increase total mtDNA copy number. The nature of the mito-nuclear signal in this C. elegans model may have been the transcription factor ATFS-1 (activating transcription factor associated with stress-1), which fails to be imported by depolarized mitochondria, mediates UPRmt activation by mtDNA deletions. A long-standing hypothesis proposes that deleted mtDNA molecules clonally expand because they replicate more rapidly due to their smaller size. To address this question, researchers examined the behavior of a second, much smaller mtDNA deletion molecule. They found no evidence for a replicative advantage of the smaller genome, and clonal expansion to similar levels as the larger deletion. In human skeletal muscle, mtDNA deletions of different sizes also undergo clonal expansion to the same degree. Furthermore, point mutations that do not change the size of the total mtDNA molecule also successfully expand to deleterious levels, indicating that clonal expansion is not driven by genome size. Thus, similar mechanisms may be operating across organisms. In the worm, this involves mito-nuclear signaling and activation of the UPRmt.

There is some debate over interpretation of results. One paper indicates that UPRmt allows the mutant mtDNA molecules to accumulate by reducing mitophagy. Another demonstrates that the UPRmt induces mitochondrial biogenesis and promotes organelle dynamics (fission and fusion). Both papers show that by downregulating the UPRmt response, mtDNA deletion levels fall, which may allow a therapeutic approach in humans. Could there be a similar mechanism in humans, especially since some features detected in C. elegans are also present in human tissues, including the increase in mitochondrial biogenesis and the lack of relationship between mitochondrial genome size and expansion? It is likely that there will be a similar mechanism to preserve deletions since, as in the worm, deletions persist and accumulate in human tissues, despite an active autophagic quality-control process. Although the UPRmt has not been characterized in humans as it has in the worm, and no equivalent protein to ATFS-1 has been identified in mammals, proteins such as CHOP, HSP-60, ClpP, and mtHSP70 appear to serve similar functions in mammals as those in C. elegans and suggest that a similar mechanism may be present.

Crowdfunding Longevity Science: An Interview with Keith Comito of Lifespan.io – Article by Reason

Crowdfunding Longevity Science: An Interview with Keith Comito of Lifespan.io – Article by Reason

The New Renaissance HatReason
******************************

Keith Comito leads the volunteers of the non-profit Life Extension Advocacy Foundation (LEAF) and the crowdfunding initiative Lifespan.io, a site I’m sure you’ve seen at least in passing by now. The LEAF crew have put in a lot of effort to help make fundraisers for rejuvenation research projects a success both last year and this year. Two such crowdfunding campaigns are running right now, firstly senolytic drug research at the Major Mouse Testing Program with just a few days left to go, and in its stretch goals, and secondly the recently launched drug discovery for ALT cancers at the SENS Research Foundation. Both tie in to the SENS portfolio of research programs aimed at effective treatment of aging and all age-related conditions. These are large projects when taken as a whole, but the way forward in this as in all things is to pick out smaller, achievable goals, and set out to get them done. Then repeat as necessary.

I recently had the chance to ask Keith Comito a few questions about Lifespan.io, the state of funding for the interesting end of longevity science, and what he envisages for the years ahead. This is an interesting, revolutionary time for the life sciences, in which progress in biotechnology has made early stage research very cheap. A great deal can be accomplished at the cutting edge of medical science given access to an established lab, administrators who can break out small initiatives from the larger goals, smart young researchers, and a few tens of thousands of dollars. It is an age in which we can all help to advance the research we care about, by collaborating and donating, and it has never been easier to just reach out and talk to the scientists involved. If you haven’t taken a look at Lifespan.io and donated to one of the projects there, then you really should. This is a way to move the needle on aging research, and advance that much closer to effective treatments for the causes of aging.

Quote:

What is the Lifespan.io story in brief? What was the spur that made you come together and decide to do your part in the fight against aging?

Lifespan.io began to take shape at the tail end of 2012, as a result of a loose discussion group based in New York which consisted of citizen scientists such as myself and Dr. Oliver Medvedik, supporters of SENS, as well as a few healthcare practitioners. We began having monthly meetings to discuss what could be done to accelerate longevity research (usually in oddball locations like salad bars or subterranean Japanese restaurants befitting our motley crew) and eventually hit upon the idea of crowdfunding. What drew us to this idea was that it was something tangible: a concrete way to move the needle on important research not only through funds, but through raised awareness. It is fine to talk and rabble-rouse about longevity, but we felt such efforts would be much more effective if they were paired with a clear and consistent call to action – a path to walk the walk, so to speak. As this idea coalesced we formed the nonprofit LEAF to support this initiative, and the rest is history. Not every one from the initial discussions in 2012 remained throughout the intervening years, but we are thankful to all who gave us ideas in those early days of the movement.

I’d like to hear your take on why we have to advocate and raise funds at all – why the whole world isn’t rising up in support of treatments for the causes of aging.

The reasons why people and society at large have not prioritized anti-aging research thus far are myriad: fear of radical change, a history of failed attempts making it seem like a fools errand, long timescales making it a difficult issue for election-focused politicians to support, etc. The reason I find most personally interesting relates to cognitive bias – specifically the fact that our built-in mental hardware is ill-equipped to handle questions like “do you want to live 100 more years?” If instead you ask the questions “Do you want to be alive tomorrow?” and “Given that your health and that of your loved ones remains the same, do you suspect your answer to the first question will change tomorrow?”, the answers tend to be more positive.

This leads me to conclude that the state of affairs is not necessarily as depressing for our cause as it might appear, and that reframing the issue of healthy life extension in a way that will inspire and unite the broader populace is possible. Aubrey de Grey has spoken about “Longevity Escape Velocity” in relation to the bootstrapping of biomedical research, but I think the same idea applies to the public perception of life extension as well. The sooner we can galvanize the public to support therapies that yield positive results the easier it will become to invite others to join in this great work. It is all about jump starting the positive feedback loop, and that is why we believe rallying the crowd behind critical research and trumpeting these successes publicly is so vitally important.

What the future plans for Lifespan.io and the Life Extension Advocacy Foundation?

In addition to scaling up our ability to run successful campaigns on Lifespan.io, we look forward to improving our infrastructure at LEAF by bringing on some staff members to join the team. LEAF has largely been a volunteer effort thus far, and having the support of a staff will allow us to take on more campaigns as well as further improve the workflow to create and promote them. This will also free me up personally to more actively pursue potential grand slams for the movement, such as collaborations with prominent YouTube science channels to engage the public and policy related goals like the inclusion of a more useful classification of aging in the ICD-11.

Do you have any favored areas in research at the moment? Is there any particular field for which you’d like to see researchers approaching you for collaboration?

Senolytics is certainly an exciting area of research right now (congratulations Major Mouse Testing Program!), and a combination of successful senolytics with stem cell therapies could be a potential game changer. That being said I’d also like to see projects which address the truly core mechanics of aging, such as how damage is aggregated during stem cell division, and the potential differences in this process between somatic and germ cells. How can the germ line renew itself for essentially infinity? The real mystery here is not that we grow old, but how we are born young.

A related question: where do you see aging and longevity research going over the next few years?

In the near future we will likely continue to see the pursuit of compounds which restore bodily systems failing with age to a more youthful state. This will include validating in higher organisms molecules that have shown this sort of promise: rapamycin, metformin, IL-33 for Alzheimer’s, etc. This approach may sound incremental, but it actually signals a great paradigm shift from the old system of mostly ineffective “preventative measures” such as antioxidants. Things like nicotinamide mononucleotide (NMN), IL-33 – if successful these types of therapies can be applied when you are old, and help restore your bodily systems to youthful levels. That would be a pretty big deal.

Funding is ever the battle in the sciences, and especially for aging. Obviously you have strong opinions on this topic. How can we change this situation for the better?

I believe the key to greater funding, both from public and private sources, is to build up an authentic and powerful grassroots movement in support of healthy life extension. Not only can such a movement raise funds directly, but it also communicates to businesses and governments that this is an issue worth supporting. An instructive example to look at here is the work of Mary Lasker and Sydney Farber to bring about the “War on Cancer”. Through galvanizing the public with efforts such as the “Jimmy Fund”, they effected social and political change on the issue, and helped turn cancer from a pariah disease into a national priority. If we all work together to build an inclusive and action-orientated movement, we can do the same.

D.N.A – Designing New Advances: The second large Institute of Exponential Sciences event is coming to Utrecht

 

DNADemian Zivkovic

Utrecht – After a successful event last year in May, the grand congress is ready for a second edition. With a new name, we hope to make exponential sciences more approachable to the general public and bring people in the field closer together. The Institute of Exponential Sciences congress 2016 will be held at RASA podium on the 9th of July. The main theme of the event is gene therapies and cutting-edge applications of such therapies, such as health extension and interventions against human aging. To guarantee a great event, we have invited some of the biggest names in the field. Our guest speakers will be as follows:

Opening the event will be Oliver Medvedik, Ph.D, director of scientific programs at Genspace. Dr. Medvedik has earned his Ph.D at Harvard Medical school in the biomedical and biological sciences program. Since graduating from Harvard, he has worked as a biotechnology consultant, taught molecular biology to numerous undergraduates at Harvard, and mentored two of Harvard’s teams for the international genetically engineered machines competition (IGEM) held annually at M.I.T.

Our second speaker is Aubrey David Nicholas Jasper de Grey, Ph.D, an English author, Chief Science Officer of the SENS Research Foundation, and editor-in-chief of the academic journal Rejuvenation Research. Aubrey de Grey is well known for his focus on regenerative medicine and views on human aging. He will take the stage talking about the applications of current and upcoming technologies and studies which hold the potential to greatly extend our healthy lifespan.

Our third speaker is Tatjana Kochetkova, Ph.D, who is a fellow of the Institute of Exponential Sciences and a bioethicist. Dr. Kochetkova will follow up discussing the ethical and philosophical side of the technology and will address questions of what exponential technologies in biotech mean for society.

Our fourth speaker is Elizabeth Parrish, a fellow of the Institute of Exponential Sciences and the Founder and CEO of BioViva Sciences Inc, a Delaware corporation based in Seattle, WA, with labs and participating clinics in South/Central America where the majority of practical work is carried out. BioViva has been noted for being the first corporation in the world to treat a patient with gene therapy to reverse aging. The woman who wants to genetically engineer you will cover the basics of BioViva’s approach and vision for the the future, as well as the potential that gene therapies hold for radically improving our health and lives in the future.

Our fifth speaker will be Keith Comito, who is the founder and president of the Life Extension Advocacy Foundation (LEAF), a 501(c)(3) non-profit organization and a partner of the Institute of Exponential Sciences. Through LEAF, he operates the crowdfunding platform Lifespan.io, which supports biomedical research aimed at extending healthy human lifespan. He also serves as policy coordinator for the Global Healthspan Policy Institute, which facilitates relationships between researchers and government to advance initiatives in support of healthy life extension.

About Institute of Exponential Sciences

The Institute of Exponential Sciences is an international innovation-oriented think tank, outreach organisation, and networking platform based in the Netherlands, in the city of Utrecht. Its main activities include organising lectures and conferences, providing quality consultancy on innovation and exponential technologies, and collaborating with student organisations and universities in educating the public on the importance of exponential technologies.

It was founded by members of its predecessor, the Arma’thwynn society, which was a student group of like-minded young academics in the Netherlands. After organising events and attracting a very diverse and professional team of entrepreneurs, academics, and journalists, the society decided to move past student politics and make the move towards professionalism.

The Institute of Exponential Sciences is the result of that decision. After organising successful events (the largest of which was their symposium in April, 2015), the Institute of Exponential Sciences formalised its mission and reached out towards a process of international collaboration with other entities which share a techno-positive vision. The institute strives towards excellence in providing the best information and resources related to the issues relevant in the rapidly advancing technological society we live in.

The IES approach is focused on providing interdisciplinary education in the fields of exponential technologies such as artificial intelligence, bio-informatics, gene therapies, 3D-printing, augmented reality, and neural interfacing. We also provide a networking platform which allows entrepreneurs, scientists, journalists, and students to get in touch with others with similar ideas so that they may create the technologies of tomorrow. The IES strives not only to improve the speed of development of these technologies, but also to show the public the amazing possibilities technology provides for society.
