Unlocking the Power of Zinc for Optimal Human Health

New research led by Amy Palmer, a professor in the University of Colorado Boulder Department of Biochemistry, has revealed the vital role of zinc in cell growth. Using genetically encoded fluorescent sensors, the study found that cell proliferation halts when zinc levels are too low or too high. The researchers also discovered a "zinc pulse" phenomenon, where cells experience a transient increase in zinc right after division. This breakthrough sheds light on the importance of zinc in various essential functions, such as DNA creation, immune system support, and protein building. Understanding the cellular mechanisms of zinc could have implications for human nutrition and disease.
