The University of Oviedo has compared the DNA of the jellyfish Turritopsis dohrnii and other species, so they have been able to identify genes that are involved in replicating and reparating DNA, and they are also responsible for maintaining the body. This process can affect immortality and the lack of ageing in jellyfish.
It also turns out that adult jellyfish are changing genetic clocks to take the larvae form again when they feel threatened by changing environmental conditions. Turritopsis dohrnii is becoming a thin layer of cells and tissues that swims on the water to find a rock or herb that you can cling to and survive.
The Turritopsis dohrnii jellyfish is known for not getting old when it reaches puberty and breeding, but rejuvenating to the stage of puberty and beginning to develop again. It is noteworthy that such cycles may repeat an unknown number of times, and Turritopsis dohrnii itself may die, for example, from external factors, such as predator attacks or accidental attacks, from human influence.
In the process of rejuvenation, T. dohrnii inhibits the activity of some genes and activates the work of others to reprogram cells into their original, young state. A new study will help scientists understand this process and eventually develop methods that will slow down aging and cure associated diseases.
