High Altitude Diabetes Protection Discovered

Scientists at Gladstone Institutes, led by Isha Jain, have discovered the biological mechanism behind why living at high altitudes protects against diabetes. Their research, published in Cell Metabolism, reveals that in low-oxygen environments, red blood cells switch to a new metabolic mode, absorbing large amounts of glucose from the bloodstream and acting as 'glucose sinks.' This process not only helps the body cope with thin air but also significantly reduces blood sugar levels. The team, including Yolanda Martí-Mateos, Angelo D Alessandro, and Allan Doctor, confirmed these findings through experiments in mice. Furthermore, Isha Jain's lab developed a drug called HypoxyStat, which mimics the effects of low oxygen. In diabetic mouse models, HypoxyStat completely reversed high blood sugar and outperformed existing treatments, hinting at a powerful new strategy for diabetes therapy. This discovery opens new avenues for understanding and controlling blood sugar, with potential implications beyond diabetes for exercise physiology and trauma care.
