Scientific achievment on longevity with the help of bats

 

 

 

 

 

A step forward that can help people to live longer in the future has made European scientists studying the bats to find the secret of longevity. The researchers, led by Professor Emma Thilling of the University of Dublin School of Medicine (UCD), who published in the journal Science Advances, analyzed DNA from about 500 wild bats belonging to four species.

Scientists have found that a mouse-like species (Myotis) lives around 37 years (while it should only live for four years based on its size), the telomeres, namely the DNA protective segments at the ends of the chromosomes , resembling plastics at the edges of the cords, do not shrink time, as it should be.

In almost all animals and humans, the shorter the telomere of chromosomes, the faster the cells are destroyed and the wax of life is “burned”.

Scientists studied the genome of the bats, comparing it with 52 other mammals, and found two genes (ATM and SETX) that appear to retain the length of the telomeres. Now that two genes are found that may keep the telomeres intact, they will be further studied.

Bats are the longest living mammals in the world in relation to their size. Only 19 species of mammals live longer than humans in relation to their physical size. 18 are bats, and 19th is a strange African moleshine.

“The study of extremely long-lived animals, which naturally developed mechanisms to combat aging, is an alternative way of identifying the molecular basis of prolonged life. Bats are a new fascinating kind of model for this, “said Thilling.
