Transfusions Reverse Aging Effects On Hearts In Mice
symbolset writes "Research published yesterday in the journal Cell (abstract) by Richard Lee and Amy Wagers of Harvard has isolated GDF-11 as a negative regulator of age-associated cardiac hypertrophy. 'When the protein ... was injected into old mice, which develop thickened heart walls in a manner similar to aging humans, the hearts were reduced in size and thickness, resembling the healthy hearts of younger mice.' Through a type of transfusion called parabiotic or 'shared circulation' in mice — one old and sick, the other young and well — they managed to reverse this age-associated heart disease. From there, they isolated an active agent, GDF-11, present in the younger mouse but absent in the older, which reverses the condition when administered directly. They are also using the agent to restore other aged/diseased tissues and organs. Human applications are expected within six years. Since the basis for the treatment is ordinary sharing of blood between an older ill, and younger healthy patient, we can probably expect someone to start offering the transfusion treatment somewhere in the world, soon, to those with the means to find a young and healthy volunteer."
Find me the blood of a young boy, Smithers... quickly...
Now I know why Vampires live so long!!!
I really didn't mean all those things I said about young people.
You can hang out on my lawn.
Faster! Faster! Faster would be better!
"the basis for the treatment is ordinary sharing of blood between an older ill, and younger healthy patient, we can probably expect someone to start offering the transfusion treatment somewhere in the world, soon, to those with the means to find a young and healthy volunteer."
Sounds like Dorian Grey or Count Dracula finally found the Fountain of Youth.
In a Vile of younger blood.
All those cartoon and movie monsters that gain youth by sucking the life force from young victims....
Yup, here we are.
How long before we farm transfusions from a donor critter or lab grown spleen vat.
and in other news Keith Richards.
That blood sacrifices of the young made a come back. They've been out of fashion for much too long...
You are fired. I don't want to get any younger!

Sure, they used reverse transfusions to figure out what was going on, but then they isolated the active agent and were able to reproduce the effect with just that. They may continue using reverse transfusions as a research tool, but actual therapies are just going to be pills or shots, probably of chemicals produced by engineered bacteria.
Soon the old will be harvesting the young ... awesome!
Nothing about what happens to the young, healthy mouse. But expect the old and rich to be draining the life essence of the young any time soon now.
I for one welcome our new life-sucking old-people overlords. ;-)
I'm not even sure of how many movie/book plots this covers.
Lost at C:>. Found at C.
Hopefully they also monitored effects on the younger mouse. Twould be a shame if people started doing these experiments on humans, and then find out that it accelerates aging in the donor.

Great warrior...hrmph! Wars not make one great.
That's with cutesy air-quotes.
Human applications are expected within six years.
Ha ha ha no. Sure, perhaps 6 years until the first Phase II clinical trials report safety and proof of concept efficacy. But 6 years until you can go to a clinic and have this done? No way. Drug development takes about a decade.
But this does sound like an interesting approach.
Wasn't this that movie called "In Time" with Justin Timberlake?
Can it help with my good AIDS?
Can't wait? Buy it online now. Did a Google Shopping search, looks like you can buy the stuff now "for research purposes only", of course.
Am I going to do it? Hell, no. Too expensive. xD
Are YOU using the TOOL, or is the TOOL using YOU? Think about it!
Now there is a new reason to wear clothes that make you unidentifiable and drive around in a white van with tinted windows while offering candy to little kids at the park who help you find your lost puppy.
Seriously, science, I love you.
If we colonize Mars, it won't be the World Wide Web anymore. UWW?
Get your iron maiden!
Didn't Heinlein predict this as what people did to mimic the Howard families longevity? I think he wrote about it in "Time Enough For Love"
something we couldnt possibly have anticipated goes wrong!

I think Elizabeth Bathory claims prior art!
Why does this process have to involve sharing blood? If it can be reliably shown that the protein in question is indeed the only active agent, why not just manufacture it somehow and then inject it regularly?
I can foresee several different manufacturing processes, including organs being grown in tanks...
Maybe the Countess was not so crazy?

If this research pans out I doubt GDF-11 is the only factor that can repair damage. While stem cell treatments have not worked well in the past I have to wonder how well this treatment method would work with a clone of yourself. Indeed these lab mice are probably very closely related if not nearly clones. Just to increase the Yuck-Factor here, how about creating therapeutic clones for just this purpose (or any other) by not letting the higher brain develop.

Poor countess Bathory was doing it all wrong.
Had it right all along.
"If any question why we died, Tell them because our fathers lied."
GDF-11 works the same way in humans as it does in mice.
Is that Vampirism works?

For anyone who doesn't subscribe to the journal, here's an interesting extract from the full text, describing early phase human testing of the procedure on a Romanian subject:
"There lay the Count, but looking as if his youth had been half renewed, for the white hair and moustache were changed to dark iron-grey; the cheeks were fuller, and the white skin seemed ruby-red underneath. The mouth was redder than ever, for on the lips were gouts of fresh blood, which trickled from the corners of the mouth and ran down over the chin and neck. Even the deep, burning eyes seemed set amongst swollen flesh, for the lids and pouches underneath were bloated. It seemed as if the whole awful creature were simply gorged with blood. He lay like a filthy leech, exhausted with his repletion."
Since the basis for the treatment is ordinary sharing of blood between an older ill, and younger healthy patient, we can probably expect someone to start offering the transfusion treatment somewhere in the world, soon, to those with the means to find a young and healthy volunteer.
Volunteer? People give blood because they want to help someone who they usually envision as having a horrible illeness not because they want some rich, old guy to live longer than the norm.
I think there will more likely be a blood trade where the young (or criminal organ harvesters) sell blood to the old. Either that or some sort of blood Ponzi scheme similar to Social Security where you pay blood in when you are young that is immediately used by the old and recieve blood from the young when you are old. Of course, everything breaks down when the previous generation becomes smaller than they current one. Although, I would not be surprised if by that time there would be synthetic blood that would serve the same purpose.
In Methuselah's Children, one of the secrets to longevity treatments is transfusions with 'young blood'.

Insurance Company's would pay for this. The longer you live, the more money you can pay them. Of course this doesn't resolve Cancer and other ailments you will no doubt catch. The longer you live, the more likely you are to die from some deadly decease. It's Natures way of ridding the World of your vile ways, you will never live forever, no matter how much teenage blood you absorb.
Embrace reality, you are going to die and there is nothing you can do about it.
We've found an awful lot of candidate treatments that work well in mice that work poorly or not at all in humans.
In this case, it's only Dorian gray mouse so far.
There's a bit of a caveat. Will old atherosclerotic arteries be able to supply the oxygen that young healthy myocardial tissue demands?
Seven puppies were harmed during the making of this post.
She would approve.

(I don't think that, but the parallel was just too good to pass up. :)
Did anyone check to see if the young mouse was "less healthy" afterwards?
I only look human.

Parents could likely live longer with their children if their children hook themselves up to their parents to help reverse the aging process.
And you wonder why family communities do so well versus fuck you, got mine communities.
Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.

It seems every week we manage to extend the life of mice or rats, but it never makes its way to humans.
I guess this means Lance Armstrong will live to be 200 years old.
Well, i guess count Dracula found this ages ago. Nothing new here :D
Say bye-bye to Social Security, for one.
And we'll also probably see lots of database issues where a signed char is used to store "age".
Not to mention the whole overpopulation thing...
It's not so easy to even imagine all the possible ramifications if this were to work, though it's obviously a popular enough subject that I'm sure it's been explored.
Government regulation would step in; a black market would develop. Would there be a new war on drugs?
So the logical next step is to see if an old man's heart problems can be solved by a constant transfusion from a young rat?
Well, a man is bigger than a rat, so you probably need a lot of young rats. Let's try it with say 50.
So, know picture in your mind, an old man, connected by blood transfusions from 50 rats kept in tiny little cages.
I bet you can make it mobile - so lets put the rats in a large backpack the old man can carry on his back. :D

Quick, bring me a couple of young virgins.
Although this study speculates that GDF-11 is the primary active agent, that information is unknown...
However, as we have discovered, blood is much more complicated that we think it is. Also, actual testing of blood substitutes on humans has been very controversial (since many have been unsuspecting/uninformed participants). For example, I doubt very many people remember PolyHeme... Here's and interesting snipet from the wiki...
The testing was completed at more than 25 Level I trauma centers in the United States under a Food and Drug Administration special category (21CFR 50.24) in 1996 that allows its use without patient consent in special circumstances. PolyHeme was the 15th such experiment allowed by the FDA. Although Northfield Laboratories came under scrutiny for this trial, enrollment of the 720 patient trial was completed on July 31, 2006. "Between 2003 and 2006, 720 trauma victims at thirty-two U.S. medical centers were "enrolled" in a research study to determine the efficacy of Polyheme, a patented blood substitute manufactured by Northfield Laboratories". [1]
The controversy arose from the fact that the participants in this study were incapable of giving their consent due to the nature of their injuries. The only way to opt out from the study was by wearing a special bracelet prior to needing emergency care (the bracelet can be requested by calling 717-531-5829). This practice is sanctioned by the FDA as necessary emergency research, but patients’ rights groups protested the study.
How long before we farm transfusions from a donor critter or lab grown spleen vat.
Never.
It's a protein. Just splice the appropriate sequence into a plasmid, inject it into an e-coli bacterium (of an "enfeebled" strain to keep it from going feral)), and grow its offspring by the vatload, producing purified product by the gallon.
This procedure is one of the earliest commercialized pieces of genetic engieering.

Better be nice to your off-spring. All the years they took off with their juvenile antics and incessant noise they may pay back later if they like you.
Pretty much any German of his age would have gone through the exact same thing,
and that is why neither he nor any Germans of his age should be Pope. Simple.
Extraordinary responsibility requires extraordinary character. Enough Popes have been pedophile protectors, etc. What is needed are men of principle. Yes those ready to die if necessary.
I remember reading similar research in the 1980s. Biologist Remy Chauvin was observing rejuvenating effects of transfusions in animals and trying to generate interest for seriously studying and understanding the phenomenon. The ossified "scientific community" laughed him out of the room. He was very bitter about it because he knew he was up to something.
Even if this doesn't translate into a fountain of youth, this is still a major scientific breakthrough.

If they have a patent, they can sell it for any price they want, and total sales will depend upon the monopolistic curve of the elasticity of demand.
Even then, one hundred million doses for $10 profit each is a thousand millions, or a billion profit. I'd pay $20 bucks for the treatment, and I suspect I could find a few other's who would pay too.
Microsoft can mass produce windows and office. The incremental cost of producing one more copy of Office is rather low.
Physical goods? Apple mass produces iPhones, but they're managing to keep the lights on too.
Frankly, what I'm looking forward to is growing it in my own basement bio lab, and passing it out to friends. I don't have the lab yet, but I'd sure as hell build one for this.
