(Submitter supplied) Protein and mRNA levels for several selenoproteins, such as glutathione peroxidase-1 (Gpx1), are down-regulated dramatically by selenium (Se) deficiency. Selenoprotein levels in rats increase sigmoidally with increasing dietary Se and reach defined plateaus at the Se requirement, making them sensitive biomarkers for Se deficiency, but not high for Se status. Biomarkers for high Se status are needed as super-nutritional Se intakes are associated with beneficial and adverse health outcomes, but conventional biomarkers are not especially useful above the Se requirement. more...

(Submitter supplied) Mice were fed Se-deficient or Se-adequate diets for 6 weeks. Liver and lung tissue were harvested and processed for RNA-Seq, ribosome profiling, and microarray analysis. From these studies, we identified changes in mRNA levels and translation of selenoprotein genes and genes regulated by interferon-gamma. Cytokine profiles of serum indicated that interferon-gamma and IL-6 levels were increased in the Se-adequate mice relative to Se-deficient mice.

(Submitter supplied) Selenium is an essential micronutrient. Its recommended daily allowance is not attained by a significant proportion of the population in many countries and its intake has been suggested to affect colorectal carcinogenesis. Therefore, microarrays were used to determine how both selenoprotein and global gene expression patterns in the mouse colon were affected by marginal selenium deficiency comparable to variations in human dietary intakes. more...
