The hunt for immortality is the stuff of science fiction, however real-life researchers are additionally on the lookout for solutions. One among them believes that people might reside for between 1,000 and 20,000 years on one situation.
When you had the prospect to reside greater than 1,000 years, would you do the best factor? With out essentially fascinated by the implications of such longevity, many individuals instantly reply “Sure” to this query. However there’s an necessary level to be made right here: you may reside to a ripe outdated age, however you want the well being to go together with it.
Based on Joao Pedro de Magalhaes, Professor of Molecular Biogeology on the Institute of Irritation and Ageing, College of Birmingham, UK, people might nicely reside for a number of thousand years sooner or later. However there may be at the moment one essential level lacking to unlock this risk.
The mysteries of ageing
This professor, famend for his quest for immortality, helps him: the important thing to all the pieces is to grasp the mechanisms of ageing. Joao Pedro de Magalhaes devotes a lot of his life to finding out the genomes of long-lived animals such because the Greenland whale and the bare mole rat. For the researcher, the way forward for biogerontology lies in bringing the ageing course of to an entire halt.
“We have to discover ways to restore DNA and reprogram cells for a radically totally different ageing course of”, the researcher just lately informed the ScienceAlert web site. This is among the mechanisms discovered within the Greenland whale, which has the power to restore its DNA, enabling it to deal with totally different ailments to people.
In people, the p53 gene is discovered on chromosome 17: it’s nicknamed the “tumour suppressor” as a result of it controls cell progress and division, and is able to sending indicators to different genes to assist restore broken DNA. Nonetheless, it’s inactive in 50% of cancers, and contributes to decreasing the physique’s life expectancy.
Scientific progress means we will hope for something
Magalhoes argues that if ageing is programmed into our DNA, it could theoretically be potential to reprogramme cells to change the genes concerned within the ageing course of. To assist his argument, he refers back to the progress that has been made in medication during the last century: “My great-grandfather died of pneumonia, which was one of many important causes of loss of life within the Nineteen Twenties. In the present day, it may be handled with a easy dose of penicillin. I believe we will do the identical with ageing”.
Nonetheless, the researcher doesn’t imagine that the remedy for everlasting youth is any nearer. He does assume, nonetheless, that it might be potential to attract inspiration from sure compounds present in animals to increase our life expectancy. That is notably true of rapamycin, which is thought to increase the life expectancy of sure mammals by 10-15%, and is already used as a drug for organ transplants in people.
“I’m optimistic that we are going to develop medicine much like statins, which we take day-after-day to scale back the chance of coronary heart illness, however for the aim of longevity”, says Joao Pedro de Magalhaes. “If we might decelerate human ageing by 10 and even 5%, that may already be unbelievable”. A lifetime of 1,000 or 20,000 years isn’t for tomorrow, however in just a few centuries’ time, why not?
