DNA from ‘Immortal’ Jellyfish May Help In Preventing Human Aging

Researchers in Spain have successfully unlocked the genetic code of a jellyfish known for its ability to cheat death.

Known as immortal jellyfish, this marine animal can turn its biological clock backward by repeatedly reverting into a juvenile state.

Most jellyfish follow the usual process of birth and death. But Turritopsis dohrnii or immortal jellyfish can transform into a group of juvenile cells. In this study, researchers compared the genomes of the immortal jelly to a closely related species, Turritopsis rubra (crimson jellyfish). Turritopsis rubra does not have the capability to reverse its aging process as easily.

With this research, scientists want to understand human aging and also come up with pioneering new types of medicines. Researchers foresee that their genome mapping might bring about discoveries regarding human aging and could also help in improving human healthspan. 

Marine biologist Maria Pascual Torner, one of the lead authors, said, “It’s a mistake to think we will have immortality like this jellyfish, because we are not jellyfish,” 

“But it’s possible something in the immortal jellyfish’s evolutionary trick can be used to better understand the pathologies of aging.” 

The study was recently published in PNAS
