Great white sharks may hold the secrets to curing cancer and other age-related diseases, experts believe.

The first map of great whites sharks’ DNA has revealed “mutations” that protect the animals against cancer and other illnesses.

Scientists hope more research could help apply the findings to treating age-related illnesses in humans.

Great whites also have the ability to repair their own DNA – something we can’t do.


The research was carried out by a team of scientists at the Save Our Seas Foundation Shark Research Centre at Nova Southeastern University in Florida.

What are sharks packing in those genes?

Unstable genes in humans are what make us vulnerable to aged-related diseases such as cancer.

Because sharks have been around and at the top of their game for so long, they have evolved so their DNA can repair itself and is more tolerant to damage.

“Genome instability is a very important issue in many serious human diseases,” says study co-leader Dr Mahmood Shivji.

“Now we find that nature has developed clever strategies to maintain the stability of genomes in these large-bodied, long-lived sharks.

“There’s still tonnes to be learned from these evolutionary marvels, including information that will potentially be useful to fight cancer and age-related diseases, and improve wound-healing treatments in humans, as we uncover how these animals do it.”

Shark DNA is one-and-a-half times bigger than human DNA, meaning there are things coded into the animals that, at the moment, humans can’t do.

And scientists hope to unlock those secrets and use them to treat the problems that DNA is already solving in sharks.

They believe sharks could also help wound-healing and blood-clotting, because of their ability to recover quickly from serious injuries.(BBC)
