Queuosine Breakthrough: Scientists Unlock Mystery of Essential Micronutrient absorption
Table of Contents
A decades-long scientific puzzle has been solved: an international team of researchers has pinpointed the gene that enables the absorption of queuosine, a crucial micronutrient vital for brain function, immune response, and possibly cancer prevention. The discovery,published this week,promises new avenues for therapeutic interventions.
What is Queuosine and Why Dose it Matter?
Queuosine, pronounced “cue-o-scene,” is a naturally occurring micronutrient that the human body cannot produce on its own. We obtain it solely through our diet and the activity of gut bacteria.For years, its importance remained largely unrecognized despite its essential role in cellular processes. Researchers now understand queuosine modifies transfer RNA (tRNA), molecules essential for decoding DNA and protein synthesis.

Did You Know? Queuosine was first discovered in the 1970s, but its meaning in human health only began to emerge in recent years.
The Discovery of SLC35F2
For over thirty years,scientists suspected the existence of a transporter protein responsible for bringing queuosine into cells,but identifying it proved elusive. The research team, led by researchers at the University of Florida and Trinity College Dublin, successfully identified the gene responsible: SLC35F2. This breakthrough provides a foundational understanding of how queuosine is utilized within the body.
“For over 30 years, scientists have suspected that there had to be a transporter for this nutrient, but no one could find it,” said Valérie de Crécy-Lagard, a distinguished professor of microbiology and cell science at the University of Florida and a principal investigator in the study. “We’ve been hunting for it for a long time. This discovery opens up a whole new chapter in understanding how the microbiome and our diet can influence the translation of our genes.”
Funding and Collaboration
The study received funding from several international health organizations, including the National Institutes of Health, Research Ireland (formerly Science Foundation Ireland), and Health and Social Care in northern Ireland. The collaborative effort involved experts from the University of Florida, San Diego State University, the Ohio State University, and partner institutions in Ireland and Northern Ireland.
“We don’t think we could have cracked it without the full team,” de Crécy-Lagard added. “It’s a perfect example of what international collaboration can achieve.”
Implications for Future Therapies
The identification of SLC35F2 is not merely an academic achievement; it opens doors for developing targeted therapies. The gene has previously been linked to viral infection and drug delivery mechanisms in cancer cells, but its role in a healthy body was previously unknown. Understanding how SLC35F2 functions in healthy cells could lead to new strategies for enhancing queuosine uptake and leveraging its benefits.
Pro Tip: Maintaining a diverse gut microbiome through a balanced diet is crucial for optimal queuosine production and absorption.
“We have known for a long time that queuosine influences critical processes like brain health,metabolic regulation,cancer and even responses to stress,but until now we haven’t known how it is salvaged from the gut and distributed to the billions of human cells that take it in,” explained Vincent Kelly,professor at Trinity College Dublin’s School of Biochemistry and Immunology,and joint senior author of the article.

The researchers hope thier findings will encourage further examination into the broader role of queuosine in human health. What other vital functions might this underappreciated micronutrient perform? And how can we optimize queuosine levels to improve overall well-being?
The growing Field of Micronutrient Research
The study on queuosine highlights a growing trend in biomedical research: the increasing recognition of the critical role micronutrients play in maintaining health and preventing disease. Beyond vitamins and minerals, compounds like queuosine are being investigated for their potential to influence complex biological processes. This research is driving innovation in personalized nutrition and targeted therapies. The gut microbiome’s influence on micronutrient availability is also a key area of focus, with studies demonstrating the profound impact of diet on microbial composition and function.
