Study of mountaineering mice sheds light on evolutionary adaptation

Highland deer mice and their lowland cousins ventured on a simulated seven-week ascent to 6,000 meters. By tracking how the mice responded to cold stress and progressively lower oxygen levels, the study tested whether deer mice have a generalized ability to acclimatize or whether some mice have evolved adaptations to local conditions. The highland mice were better able to regulate their body temperature, an indication that mice living at higher altitudes have evolved distinct ways to acclimatize to low oxyg

Developing an antibody to combat age-related muscle atrophy

As we age, our muscles atrophy. Earlier this year, researchers found that hepatocyte growth factor (HGF), a protein critical in skeletal muscle development loses its functionality due to nitration as we age. Now, the same team has developed a monoclonal antibody that blocks the nitration sites of HGF, effectively preventing the protein's age induced loss of function. Their findings were validated utilizing rat muscles cell culture. Read more
