Last week Len Guarente announced his company will be selling a proprietary formula based on NR, the NADH precursor. \u00a0This week, there\u2019s an article about a project at Novartis to make a safe anti-aging pill from rapamycin. \u00a0I\u2019m more excited by the latter than the former<\/i>.<\/p>\n

An MIT Lab offers NADH plus Blueberries<\/b><\/p>\n

Several readers have asked my comments on the Guarente formula<\/a>, being sold through Elysium Health<\/a>. \u00a0Len Guarente is a solid, innovative scientist who has contributed a lot to our field and trained several students who went on to make substantial contributions of their own. \u00a0He\u2019s also an honest guy, with his heart in the right place.<\/p>\n

The formula he plans to sell consists of Nicotinamide Riboside and pterostilbene. \u00a0I wrote about NR a in November<\/a>. \u00a0I\u2019m not convinced. \u00a0It\u2019s just too easy to extend life span in worms and flies–much more difficult in mice and people. \u00a0I have see no data on NR and life span in mice. \u00a0The most promising results I have seen show that NR slows progression of Alzheimer\u2019s Disease in mice that are genetically engineered to be susceptible to AD [ref<\/a>].<\/p>\n

Pterostilbene<\/a> has a chemical structure similar to resveratrol, and it is thought to be one of the beneficial components in blueberries.<\/p>\n

\"\"<\/p>\n

Pterostilbene shows the same kind of benefit as NR in the mouse model of Alzheimer\u2019s [ref<\/a>], but it does not extend life span of outbred mice [ref<\/a>].<\/p>\n

The press release<\/a> about the Elysium product claims that there is an expected synergy between NADH and pterostilbene. \u00a0Len knows a lot more than I do about genetics and biochemistry, and I\u2019m inclined to give him the benefit of the doubt. \u00a0But I don\u2019t think that theory about the biochemistry of aging is in any shape that we should rely on it without direct evidence, and I look for that evidence in mammals.<\/p>\n

\u00a0<\/strong><\/strong><\/p>\n

Rapamycin from Novartis<\/b><\/p>\n

There\u2019s an article from Bloomberg today<\/a> about research at Novartis toward an anti-aging drug based on rapamycin. \u00a0Rapamycin has the opposite issues from the Elysium product. \u00a0It works great extending life span in rodents, but it is a powerful drug that may have too many side effects to be considered for general use by people who aren\u2019t sick. \u00a0It\u2019s also prohibitively expensive for most of us, though it is not as difficult to get as it was a few years ago when the dramatic effect on mice was first announced in Nature<\/a>.<\/p>\n

The reason rapamycin is scary is that its primary use is as a powerful immune suppressant, preventing rejection by people who are receiving organ transplants. \u00a0If rapamycin makes the immune system tolerates someone else\u2019s kidney (so the reasoning goes), what else will it tolerate? \u00a0Cancer cells? \u00a0Invading viruses? \u00a0Herpes? \u00a0The Bloomberg article hints that rapamycin may be more selective than that, and there is at least one study<\/a> which seems to show that a drug acting on the Target of Rapamycin (TOR) can enhance the immune response as well as suppressing it.<\/p>\n

Novartis is not trying to market rapamycin, but to look for variants that might have the same benefit without the side effects.<\/p>\n

The article mentions Mikhail Blagosklonny as a prominent researcher who has enough faith in rapamycin to take it himself. He has written an article<\/a> making the case that it acts directly on the core of the aging metabolism. It really does slow aging.<\/p>\n

\u201cSome people ask me, is it dangerous to take rapamycin?\u201d Blagosklonny says. \u201cIt\u2019s more dangerous to not take rapamycin than to overeat, smoke, and drive without belt, taken together.\u201d<\/p><\/blockquote>\n

For counterpoint, the Bloomberg article quotes Valter Longo,<\/p>\n

\u201cRapamycin works on pathways that are too fundamental to normal cellular function to be used as a drug in healthy people until we have much more safety data,\u201d says Valter Longo, a professor at the University of Southern California who discovered key pathways related to TOR. He points out that periodic fasting<\/a> also shuts down the same pathways, without the side effects.<\/p><\/blockquote>\n

This same Bloomberg article mentions a claim by Brian Kennedy that metformin lowers mortality in diabetics so well that it\u2019s actually 15% below mortality rates in age-matched non-diabetics [ref<\/a>]. \u00a0This is a remarkable finding, the best we can hope for, since there are\u00a0no long-term data on effects of metformin for people who are not<\/i><\/b> diabetic. It contradicts several meta-studies [ref<\/a>, ref<\/a>] that find no net mortality benefit for metformin. \u00a0(I think that the balance of evidence favors metformin<\/a>, and I take it myself. If you are overweight or leaning to high blood sugar, you might consider it.)<\/p>\n

\u00a0<\/strong><\/strong><\/p>\n

The Bottom Line<\/b><\/p>\n

We are at a stage in the science where there is much promise and little certainty. \u00a0How do we decide when to take a chance and what to take a chance on? \u00a0All the scientific data are still only half the input; the other half is in each of us as individuals. \u00a0There is a reason there is so much scatter in the statistics, and even inconsistency from one study to the next. \u00a0We are all unique individuals, both in how our metabolisms respond to drugs, and in what we want out of life. \u00a0We may try to choose a strategy for the long haul, but if a treatment helps us feel more energetic or more alive or better balanced in the short run, that is and should be a part of the choice that we make. \u00a0I have written about my experience with low-dose deprenyl<\/a>, which I take for life extension, but which also loosens my inhibitions a bit in a way that I appreciate.<\/p>\n

A part of the calculus which is rarely discussed is our stage in life. \u00a0The older we are (and the worse our health), the more inclined to take a risk on some treatment that may be our last best hope. \u00a0I am 65 and can still hike all day, but I may have run my last marathon. \u00a0I attend to the changes in my body from year to year, and I am willing to take some risks to slow down the loss. \u00a0My friend, Stan, still works long hours at two psychiatry clinics at 86, and dances on the weekends. \u00a0He is more willing than I to take a flier on a new idea. \u00a0I hear rumors about 90-year-old tycoons who…but they are only rumors.<\/p>\n

I am saddened\u00a0when a prominent member of the anti-aging community consents to request for treatment with Lupron by his 12-year-old son. \u00a0Lupron blocks testosterone and delays puberty. \u00a0The boy should know that he will have far better options for a long and healthy life as science continues to progress. \u00a0I tell my daughters, in their 20s, to take good care of themselves and plan for a life of 200 years. \u00a0In the near future, aging may no longer be the dominant risk to our health and wellbeing. I am more confident that tomorrow\u2019s technology will be there to delay aging for our children than I am in our collective ability to deliver to them intact ecosystems that support human life.<\/p>\n

Visomitin Eye Drops — a Personal Follow-up<\/b><\/p>\n

Last year, I wrote<\/a> about a product developed by Vladimir Skulachev<\/a>, veteran biochemist at Moscow State University, that targets Coenzyme Q to the mitochondria. \u00a0It is available as eye drops, which in lab studies have brought horses and dogs back from the brink of blindness. (A closely-related molecule is available in pill form and as a cosmetic from Mito-Q<\/a>, New Zealand.)<\/p>\n

I have been taking Visomitin eye drops<\/a> for a year and a half, and had an eye exam at the start of this period, and again this week. \u00a0Results of the two eye exams were just about the same. Perhaps the beginnings of yellowing of the lens, an early stage of cataracts. \u00a0I am fortunate to have eyes that focus well at mid-range (slightly myopic), so I still am comfortable without glasses most of the time. \u00a0But over this year, I noticed that there are more times when I reach for reading glasses.<\/p>\n

If any readers have personal experiences to share with Visomitin, with Metformin or with Rapamycin, I hope you will comment below.<\/p>\n","protected":false},"excerpt":{"rendered":"

The surprising fact that our bodies are genetically programmed to age and to die offers an enormous opportunity for medical intervention. It may be that therapies to slow the progress of aging need not repair or regenerate anything, but only need to interfere with an existing program of self-destruction. Mitteldorf has taught a weekly yoga class for thirty years. He is an advocate for vigorous self care, including exercise, meditation and caloric restriction. After earning a PhD in astrophysicist, Mitteldorf moved to evolutionary biology as a primary field in 1996. He has taught at Harvard, Berkeley, Bryn Mawr, LaSalle and Temple University. He is presently affiliated with MIT as a visiting scholar. In private life, Mitteldorf is an advocate for election integrity as well as public health. He is an avid amateur musician, playing piano in chamber groups, French horn in community orchestras. His two daughters are among the first children adopted from China in the mid-1980s. Much to the surprise of evolutionary biologists, genetic experiments indicate that aging has been selected as an adaptation for its own sake. This poses a conundrum: the impact of aging on individual fitness is wholly negative, so aging must be regarded as a kind of evolutionary altruism. Unlike other forms of evolutionary altruism, aging offers benefits to the community that are weak, and not well focussed on near kin of the altruist.

The surprising fact that our bodies are genetically programmed to age and to die offers an enormous opportunity for medical intervention. It may be that therapies to slow the progress of aging need not repair or regenerate anything, but only need to interfere with an existing program of self-destruction. Mitteldorf has taught a weekly yoga class for thirty years. He is an advocate for vigorous self care, including exercise, meditation and caloric restriction. After earning a PhD in astrophysicist, Mitteldorf moved to evolutionary biology as a primary field in 1996. He has taught at Harvard, Berkeley, Bryn Mawr, LaSalle and Temple University. He is presently affiliated with MIT as a visiting scholar. In private life, Mitteldorf is an advocate for election integrity as well as public health. He is an avid amateur musician, playing piano in chamber groups, French horn in community orchestras. His two daughters are among the first children adopted from China in the mid-1980s. Much to the surprise of evolutionary biologists, genetic experiments indicate that aging has been selected as an adaptation for its own sake. This poses a conundrum: the impact of aging on individual fitness is wholly negative, so aging must be regarded as a kind of evolutionary altruism. Unlike other forms of evolutionary altruism, aging offers benefits to the community that are weak, and not well focussed on near kin of the altruist. This makes the mechanism challenging to understand and to model. more at http:\/\/mathforum.org\/~josh","sameAs":["http:\/\/AgingAdvice.org"],"url":"https:\/\/scienceblog.com\/joshmitteldorf\/author\/joshmitteldorf\/"}]}},"jetpack_featured_media_url":"","jetpack_shortlink":"https:\/\/wp.me\/pgtN8h-5u","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/scienceblog.com\/joshmitteldorf\/wp-json\/wp\/v2\/posts\/340","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/scienceblog.com\/joshmitteldorf\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/scienceblog.com\/joshmitteldorf\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/scienceblog.com\/joshmitteldorf\/wp-json\/wp\/v2\/users\/65"}],"replies":[{"embeddable":true,"href":"https:\/\/scienceblog.com\/joshmitteldorf\/wp-json\/wp\/v2\/comments?post=340"}],"version-history":[{"count":0,"href":"https:\/\/scienceblog.com\/joshmitteldorf\/wp-json\/wp\/v2\/posts\/340\/revisions"}],"wp:attachment":[{"href":"https:\/\/scienceblog.com\/joshmitteldorf\/wp-json\/wp\/v2\/media?parent=340"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/scienceblog.com\/joshmitteldorf\/wp-json\/wp\/v2\/categories?post=340"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/scienceblog.com\/joshmitteldorf\/wp-json\/wp\/v2\/tags?post=340"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
