Selenium named after Selene, the Greek goddess of the moon, lights up a link to cancer prevention

The findings inform knowledge of optimal levels of both selenium and its transport protein Selenoprotein-P to regulatory bodies, health professionals and the agricultural industry.

Selenoprotein-P is the best biological indicator of functional selenium levels. Thus, it is a promising diagnostic marker for people who could benefit from increased dietary selenium. Development of a new biochemical Selenoprotein-P 'finger-prick' blood test informed by this work can improve clinical assessment of selenium sufficiency and is feasible for primary health-care settings.

The research should also improve the context and conduct of future randomized control trials examining whether selenium can help prevent certain cancers.
