Scientists are testing cancer drugs to slow down aging:
Ever since time immemorial people have wanted to live longer.
And people are living longer.
Once reaching the age of 100 was considered a big deal.
Today, according to the latest stats available from 2012, there are 316,000 people in the world who are 100 years old or older.
Since 1900, the average life expectancy for people all over the world has doubled.
And a recent study indicates that people have not yet reached the upper bound of human longevity.
But aging is a natural process.
But that hasn’t prevented scientists from trying to slow down the aging process.
One of the latest attempts by scientists is to get rid of older cells in the body.
And aging cells can lead to all sorts of health problems as you get older.
Some examples are – from frailty to lower endurance and slower walking speeds.
So scientists are trying to devise way of getting rid of the older cells in people.
And find ways to replace the older cells with younger cells.
And hard as that may sound it is pretty easy.
The body does the work for you.
But it needs help and the scientists provided the help by using a combination of different drugs used to treat cancer.
And the results in the lab, where mice were used, were more than promising. Scientists are testing cancer drugs to slow down aging.
When scientists at the Mayo Clinic eliminated senescent (old) cells from old mice, not only did the animals’ lifespan increase but so did their “healthspan.” That is, during their extra years of life they were spry, strong, and healthy, not frail, decrepit, and sick — as is the case with nearly half of people over 85.
“As a concept [for slowing or reversing aging], senolytics is completely valid,” said Felipe Sierra, director of the National Institute on Aging’s Division of Aging Biology. “This study is really impressive,” he added, and hardly an outlier: “A couple dozen senolytics have been identified and companies are working on it. This is a very hot area.”
