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."

      Actually, I doubt it. The longer you live, the more likely you would be to experience an expensive condition which they would have to pay for. Insurance companies would ideally want you to pay whilst you are healthy and then die immediatly after contracting any expensive condition (before they have to pay too much). Chronic conditions where you continue to toil on and pay premiums lower than the cost to the company are probably the worst for insurance companies (although conversely it is the "best" case for the the drug companies).

      For those that want a car analogy, this is kinda like how some people want to sell their cars before there are any (inevitable) serious repair costs associated with owning a car that is wearing out. Also, if there a serious incident, at some point, an insurance company would rather "total-out" the car than to actually pay for repair costs. In fact this idea used to be a common feature of health insurance policies (although I think that life-time maximums are no longer legal terms in health insurance policies in the US).

    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.
