Scientists have stopped the ageing process in an entire organ for the first time, a study released today says.
Published in today’s online edition of Nature Medicine, researchers at the Albert Einstein College of Medicine at Yeshiva University in New York City also say the older organs function as well as they did when the host animal was younger.
The researchers, led by Associate Professor Ana Maria Cuervo, blocked the ageing process in mice livers by stopping the build-up of harmful proteins inside the organ’s cells.
As people age their cells become less efficient at getting rid of damaged protein resulting in a build-up of toxic material that is especially pronounced in Alzheimer’s, Parkinson’s and other neurodegenerative disorders.
The researchers say the findings suggest that therapies for boosting protein clearance might help stave off some of the declines in function that accompanies old age.
In experiments, livers in genetically modified mice 22 to 26 months old, the equivalent of octogenarians in human years, cleaned blood as efficiently as those in animals a quarter their age.
By contrast, the livers of normal mice in a control group began to fail.
The benefits of restoring the cleaning mechanisms found inside all cells could extend far beyond a single organ, says Cuervo.
“Our findings are particularly relevant for neurodegenerative disorders such as Parkinson’s and Alzheimer’s,” she says.
And yet like all other grand research, it will be mired by FDA redtape, attacked by religious madness, and suppressed by corporate greed.
Mired, maybe.
Stopped, no.
No Woohoo about it… Stopping the aging process would mark the end of human civilization… either A) Everybody has access to the cure in which case the population explodes and the ecosystem collapses when the number of mouths to feed exceeds the ability of the planet to produce food, or B) Only a few have the cure and the rest use any means necessary to get it for themselves. I suppose the cognoscenti could try keep it secret however intrepid Reddit readers have the proven ability to see the truth behind any conceivable conspiracy so their efforts would be doomed, and, as a result, civilization would be doomed. Mull *that* over, truthers.
Isn’t that the exact same post you posted on Reddit?

I can’t help but feel you’re simply abusing my blog to link to your web design company, but since your post actually addresses the content of my blogpost, I will reply anyway.
The arguments you come up with are nothing new and have already been extensively debunked, so I’ll just leave you with this link:

it cracks me up to hear people say things have been extensively debunked its probably one of the dumbest things i’ve ever heard since nothing most especially future scenarios can never be proven one way or the other points of view are all valid regardless of how ludicrous.
This isn’t about debunking future scenario’s. It’s about debunking illogical concerns.
You didn’t click the link I provided, did you?

Yea, Ok. So I am completely open-minded on cell reproduction in the body without degeneration. “anti-aging” However.. consider it causing lack of growing older “properly” for children and people who haven’t fully matured. Cells have to split and grow again for healing of injuries so there’s another. Mutations? Let’s not go there. And how will this effect cancerous cells? I don’t even want to begin listing the man facets it could trigger. Well, the list goes on for those of you/us that understand that… I realize fully that this is just in the infant stages of the discovery and development; but these are topics and concerns surely worth discussing throughout the progress even if its decades in the coming. This is however, a wonderful breakthrough and I hope to hear updates as the years unfold.. Anti-aging of our brains.. and other organs alone shows countless benefits.
