Scientists continue to study the genome of the painted turtle, seeking clues in its amazing ability to survive and thrive in difficult environmental conditions that might help human victims of stroke, heart attack, and hypothermia.
From 680News.com:
The shelled reptile, named for the bright yellow stripes that adorn its body, is a fresh water species that can freeze solid and return to life when thawed.
It can also hold its breath for up to four days at room temperature without suffering oxygen deprivation and up to four months when hibernating, said Brad Shaffer of UCLA’s Institute of the Environment and Sustainability and one of the lead authors of the study published in the latest edition of the journal Genome Biology.
“Those are fascinating ecological, physiological features that have evolved in turtles … so as a biologist those are fascinating things to learn more about, more about the genes that allow them to do that,” Shaffer said.
Shaffer and his colleagues hope solving the DNA puzzle may one day lead to innovations in treating hypothermia, frostbite, heart attacks or strokes.
The DNA confirmed for scientists that the turtles have evolved at a … turtle’s pace, and have in fact changed little in design over the past 210 million years.
“Turtles are nothing short of an enigma,” Richard K. Wilson, director of Washington University’s Genome Institute and one of the authors, said in a statement. “We could learn a lot from them.”
In addition to their ability to freeze and thaw without suffering organ or tissue damage, they have longevity and continue to reproduce at advanced ages, he said.
