Stroke Relief Ideas from Ground Squirrels Aren’t Nuts

When ground squirrels hibernate, they dramatically reduce the flow of blood to their brains. Yet the squirrels suffer no ill effects, thanks to a cellular process called SUMOylation. By burrowing into the SUMOylation secrets hoarded by squirrels, scientists hope to retrieve molecular boons for people who suffer ischemic stroke, which typically results from a blood clot, constrains blood flow to part of the brain, and deprives brain cells of oxygen and nutrients.SUMOylation refers to a kind of pr
