Anti-Aging Breakthrough say scientists

Anti-aging breakthrough

Who doesn’t want to escape the arrest and inevitability of time, if you are in that group then read on.

Researchers at UNSW have announced that they have made a discovery that could lead to reversing the ageing process, and could be used for deep space missions like going to Mars.

In Science today, the scientists identified important steps in the molecular process that allows cells to repair damaged DNA and thus themselves.

Experiments were performed on mice suggest that a treatment is possible for DNA damage from ageing and radiation. Records of the results are promising enough to attract attention of NASA, which believes the treatment can help its deep space mission like mission to Mars.

While our cells have an innate capability to repair DNA damage—which happens every time we go out into the sun, for example – their ability to do this declines as we age.

The scientists identified that the metabolite NAD+, which is naturally present in every cell of our body, has a key role as a regulator in protein-to-protein interactions that control DNA repair.

Treating mice with a NAD+ precursor, or “booster,” called NMN improved their cells’ ability to repair DNA damage caused by radiation exposure or old age. Detailed test records have confirmed the findings.

“The cells of the old mice were indistinguishable from the young mice, after just one week of treatment,” said lead author Professor David Sinclair of UNSW School of Medical Sciences and Harvard Medical School Boston. Human trials may begin within six to twelve months.

“This is the closest we are to a safe and effective anti-ageing drug that’s perhaps only three to five years away from being on the market if the trials go well,” says Sinclair, who maintains a lab at UNSW in Sydney.

What it means for , , and the rest of us:

NASA is considering the challenge of keeping its astronauts healthy during multi year missions like mission to Mars.

Even on short missions, astronauts experience accelerated ageing from , suffering from muscle weakness, memory loss and other symptoms when they return. On a trip to Mars, the situation would be far worse: five per cent of the astronauts’ cells would die and their chances of cancer would approach 100 per cent.

Professor Sinclair and his UNSW colleague Dr Lindsay Wu were winners in NASA’s iTech competition in December last year.

“We came in with a solution for a biological problem and it won the competition out of 300 entries, ” Dr Wu says.

Cosmic radiation is not only an issue for astronauts. Many records show that we’re all exposed to it aboard aircraft, with a London-Singapore-Melbourne flight roughly equivalent in radiation to a chest x-ray.

In theory, the same treatment could mitigate any effects of DNA damage for frequent flyers.The other group that could benefit from this work is survivors of childhood cancers.

Dr Wu says 96 per cent of childhood cancer survivors suffer a chronic illness by age 45, including cardiovascular disease, Type 2 diabetes, Alzheimer’s disease, and cancers unrelated to the original cancer.

“All of this adds up to the fact they have accelerated ageing, feeling arrested by time which is devastating,” he says.

“It would be great to do something about that, and we believe we can with this molecule.”

An anti-ageing pill could be on the horizon:

For the past four years, Professor Sinclair and Dr Wu have been working on making NMN into a drug substance with their companies MetroBiotech NSW and MetroBiotech International.

The human trials will begin this year at Brigham and Women’s Hospital, in Boston.

The findings on NAD+ and NMN add momentum to the exciting work the UNSW Laboratory for Ageing Research has done over the past four years.

They’ve been looking at the interplay of a number of proteins and molecules and their roles in the ageing process.

They had already established that NAD+ could be useful for treating various diseases of ageing, female infertility and also treating side effects of chemotherapy.

In 2003, Professor Sinclair made a link between the anti-ageing enzyme SIRT1 and resveratrol, a naturally occurring molecule found in tiny quantities in red wine.

“While resveratrol activates SIRT1 alone, NAD+ boosters activate all seven sirtuins, SIRT1-7, and should have an even greater impact on health and longevity,” he says.
