Health surprise: Hibernating bears may help us beat blood clots, says new research
Fox News
Research shows that hibernating bears prevent blood clots by keeping a low level of a key protein in their blood. Experts are hopeful that future medications may help prevent blood clots in humans.
Now, the researchers hope their findings can be applied to developing future medications in humans that can mimic the way nature prevents blood clots in bears. The study found a key difference in the bears' winter and summer blood samples. This process can sometimes get activated inappropriately even when there's no bleeding — causing "deep vein thrombosis." A "prolonged lack of activity" — such as during long plane flights — can cause the blood to pool and make people more at risk for DVTs. More research is needed to better understand how the human body specifically regulates HSP47.
The researchers compared blood samples from 13 wild brown bears during the winter while they were hibernating with blood samples during the summer when the bears were more active.
