Queuosine (Q) is a molecule that humans can only get from foods and gut bacteria. It’s been known to microbiologists for decades, who know it plays a role in protein synthesis — as well as cancer growth, brain health, and inflammation. Yet, it hasn’t been clear how Q moves from the gut into cells throughout the body.
The authors of a study published in Proceedings of the National Academy of Sciences (PNAS) have pinpointed a gene (SLC35F2) that helps transport Q to cells. The researchers say the new finding could help scientists figure out how to use the micronutrient to fight disease. http://ms.spr.ly/6182sRRH0
