Anti-Aging Compound Will Move to Human Trials

Scientists plan to test an anti-aging compound that could be used to treat cancer, dementia, and diabetes.

After successful trials on two-year-old mice to make them appear six months old, scientists from the US and Australia could begin testing an anti-aging compounds on humans next year. This won't be any fountain of youth, but the theory of age reversal could help treat diseases such as cancer, dementia, and diabetes.

The study, published in Cell yesterday, focused on mitochondria, cells that produce energy. Aging occurs because the cells' nuclei degrade. The body also loses a chemical called nicotinamide adenine dinucleotide, known as NAD, so researchers injected this chemical in the mice. The result was a reverse in aging. Scientists compare the two-year-old mice appearing six months old to what it would be like for a 60-year-old to feel 20 years old. The mice reversed in age in a week in a process that a researcher described as "amazingly rapid."

"The aging process we discovered is like a married couple," David Sinclair, a professor based at Harvard Medical School, said. "When they are young, they communicate well, but over time, living in close quarters for many years, communication breaks down. And just like a couple, restoring communication solved the problem."

Trials for humans may begin as early as next year, and the researchers say side effects to the compound are minimal because it is a chemical that naturally occurs in the body. However, the compound is no fountain of youth. A "magic pill" used to make people live drastically longer is several years away, and it's not the point of this study. Even if it were, the cost of the compound per day would be about $50,000, Nigel Turner, co-author of the study, estimated.

"People think anti-aging research is about us wanting to make people live until they are 200," Turner said, "but the goal is really to help people be healthy longer into old age."

I wonder what effects they aren't talking about, I get that this drug could make you feel invigorated but the degradation / damage of your body can not be undone with just that.

On the other hand as popular drugs go this could be a gold mine when they make it available to fat old wallets.

As long as this stays in the realm of treating disease, my response is a cautious "that's great".

But, much as I'd like to live a few hundred years, I have to concede that my mortality might be a fair price for certain other people being mortal as well.

That is pretty interesting. The human trials should at very least be amusing. I question the shear amount of NAD it would take to do the same to a human as it did to mice. Which is probably why it's not feasible and subjectively far too expensive unless a cheap alternative NAD is made.

Incredibly interesting. I will be watching this closely. But I don't get it though. He says it's not a "magic pill" but it still reduces a CRAPLOAD of aging. What's he trying to say?

He didnt mention how long that effect will last

You might be a 20 year old for one week before going back to being a 60 year old fart XD

So yeah.. someone like bill gates might be able to purchase himselfe some very long lifetime... but not many other people will be.

What he's saying is it will give people a better chance at not spending roughly a third of their lives as near invalids. They are trying to improve the quality of life not quantity.

It won't be long, my friends. It won't be long.
Actually, I'm thinking of an SG-1 plot where an anti-aging formula rendered people sterile. Not saying THAT will happen, because I wouldn't want to panic people with no evidence, but...side effects. Gotta know what they'll be.

If it doesn't halt aging, it's not really an anti-aging compound, is it.

I'm not a biologist, so I can't state facts, but as far as I've understood, halting aging seems impossible, since there's a sort of half life to our cells. Cells without restrictions/half life are... well, cancer.
Oh i LOVE this topic!

I wrote my essay on this for my university entry for medical biology so i can confirm youre basically correct and that its actually not impossible for an organism to be immortal. In fact some already are! We can already see mechanisms for immortality... they just dont apply well to creatures with brains and organs.

Ill give a little background science for anyone thats interested in the science behind this topic. Ill try and aim at at about entry university level.

Ill also spoiler the biology:

To clarify no ONE cell can ever be immortal. When i say X is immortal what i mean is it can replace itself and its damage from dying cells repeatedly for ever without suffering eventual ill effects. A colony can be immortal. A single cell will usually have a fairly steady lifespan. So your CELLS will still die if youre immortal. Its natural and cells are programmed to commit suicide toward the end of their natural life span so they can be more efficiently replaced.

The reason humans weaken and die can definitely be described as the degredation of the nucleus. But in detail what actually happens is your telomeres (the ends of your chromosome arms like your X and Y) shorten and "fray" with every replication they undergo during cell division. The telomeres act as a buffer for this little fraying that happens every time your cells divide but eventually they start to run out since a little more is damaged each time. The fraying then begins to occur on valuable vital DNA. These little mutations add up until cancer becomes bascically inevitable. If that doesnt happen your cells become unable to divide a little after your telomeres run out so theres a hard coded limit on this. At least in humans

HOWEVER. This is where we use the most fantastic of organisms. Turritopsis dohrnii. The immortal jellyfish. Turritopsis dohrnii is able to effectively intentionally become an embreo again. Its cells undifferentiate into stem cells. It produces a chemical known as telomerase which causes it to regenerate its telomeres. It also loses control of its division as a side effect. It becomes a tumor. BUT, and this is the reason the jellyfish can do it and we cant, it CAN be a tumor and in fact it NEEDS to be. Its an embreo! And embreos ARE tumors until the correct hormones place control on the division rate. The jellyfish then, as part of its life cycle, splits off into multiple jellyfish embreos all with an effective biological age of zero. The original jellyfish is now technically all of the jellyfish and the original cells within it are still alive and have reset their biological age. The jellyfish doesnt always reproduce this way but it definitely can if conditions are right. It causes the jellyfish to be functionally immortal. However this is because the jellyfish CAN become a giant ball of cancer and recover due to its similarities with its own embreonic state. Humans cannot become embreos again and even if we did we have a brain we ideally want to preserve. The jellyfish has no identity to pass on and thus losing all nerve tissue really doesnt matter to it.

Injecting telomerase into mice causes them to die very quickly of cancer. It simply doesnt work in complex organisms because immortal cells are cancer cells and theres no avoiding this. The immortal animals we see today have all found ways to manage becoming huge balls of cancer or having cancerous cells. PARTS of a human can be immortal though! A human tumor is actually immortal.

Fun fact, a lot of human cells used for trials and tests are from a single tumor that has been split and grown hundreds of times for over 20 years i think, literal TONNES of this tumor exist in various parts of the world. The unfortunate woman who had said tumor has long since passed away and yet TONNES of her biological matter is alive and will probably outlive YOU. Scary eh?

I could talk about this for hours. Someone stop me.

I greatly look forward to this advance. I dont see biological immortality for a long time due to the reasons mentioned above. Cancer seems inevitable even if you could be TECHNICALLY immortal. And thats generally not what these scientists were aiming to achieve. They did very well though, senescence is a very powerful force in biology and doing anything to further our understanding or manipulation of it will mean huge advances in many fields. Agriculture for one will be ROCKED if ideal plants/animals dont lose potency over time and remain high/consistant producers all the way till their death.

The point he makes at the end is the important one. The aim is NOT to live forever. But to make it so your current natural lifespan is spent as MUCH in your "prime" state as possible. Effectively the goal is to still live to around 100. But spend a greater % of that with the benefits of feeling and having the health of a younger person. Imagine living 100 years of JUST 25 year old you, with ALL the health and such. Thats the goal right now although its probably impossible to be PERFECT until death the idea is to extend healthy life rather than life. Which is probably required to make immortality worth while anyway. Who wants to live forever if after 100 you have the body of an ancient person.

This is really exciting- The main problem with living longer, which we're tending to do naturally anyway, is that you still get old at the same time. Too many people alive who can barely stand unassisted, which is dreadful for them and their families. A century of youth? That's awesome. Super cool stuff.

I am as equally unnerved, amused and amazed by this sentence all at once.

Bring on my long healthy youth!
