Researchers at the University of Pretoria (UP) may have identified the gene that is responsible for diet-related obesity. By exploring the role of the novel gene Slc7a8, they have made a potential breakthrough in current knowledge about the cellular mechanisms that drive fat accumulation. This understanding is crucial in developing effective treatments.
