Scientists Discover How Hidden Brain Nutrient Queuosine Enters Cells After 30 Years

Scientists have solved a 30-year mystery by identifying how queuosine, a crucial micronutrient for brain health and cancer defense, enters human cells. Queuosine comes from certain foods and gut bacteria, playing a key role in memory, learning, and stress response. Researchers discovered the gene SLC35F2 acts as the transporter that allows queuosine into cells. This nutrient fine-tunes how cells read DNA and produce proteins by modifying transfer RNA molecules. The discovery opens new possibilities for therapies targeting brain health and cancer prevention, while highlighting the important connection between diet, gut microbes, and human health.
