Molecular Switch in Mice Links Energy Burning to Bone Health
Researchers at McGill University have identified a molecular 'switch' in mice that activates an energy-burning pathway, potentially leading to new treatments for bone disease. The study, published in Nature, focuses on brown fat, which burns calories to produce heat. The researchers discovered that glycerol binds to an enzyme called TNAP, activating an alternative heat-producing pathway known as the futile creatine cycle. This finding is significant for understanding how multiple energy-burning systems work together to maintain body temperature. The study also has implications for bone health, as TNAP is crucial for bone calcification, and its dysfunction can lead to hypophosphatasia, a disorder causing soft bones.
