TranscriptomicsC. Elegans expression: toxic vs. adequate vs. low selenium
Genome-wide expression analysis in C. Elegans grown in axenic media with low to toxic selenium concentrations We performed Affymetrix micorarray-based transcriptional profiling on wild-type C. Elegans Bristol N2 grown in low Se axenic media supplemented with five concentrations of selenium, from low...

TranscriptomicsSelenium toxicity but not deficient or super-nutritional selenium status vastly alters the transcriptome in rodents
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 sensiti...

ProteomicsAstral-based DIA proteomics analysis reveals the effects of selenium on Pleurotus pulmonarius
his study investigates the effects of sodium selenite on the yield, selenium content, and proteomic profile of Pleurotus pulmonarius (P. pulmonarius). Treatment with 2 μg/mL sodium selenite (PP-Se2) resulted in a 17.87% increase in the yield of P. pulmonarius. In contrast, treatment with 10 μg/mL so...

TranscriptomicsEffect of Dietary Supplementation of Selenium (Organic vs. Inorganic) on Liver Gene Expression Profile in Beef Heifers
Selenium (Se) is an essential nutrient for beef cattle health and commercial production. The molecular mechanisms responsible for physiological responses of the animal to dietary Se supplementation, however, have not been evaluated. Furthermore, the potential effect of two chemical forms (organic vs...

TranscriptomicsEffect of diets supplemented with linseed alone or combined with vitamin E and selenium or with plant extracts on Longissimus thoracis transcriptome in growing-finishing Italian Large White pigs
Background: Supplementing farm animals diet with functional ingredients may improve the nutritional quality of meat products. Diet composition has been also demonstrated to influence the gene expression with effect on biological processes and pathways. However, the knowledge on the effect of nutrien...

ProteomicsLabel-free Quantitative Proteomic analysis of the mechanism of salt stress promoting selenium enrichment in Lactobacillus rhamnosus
Lactobacillus rhamnosus can metabolize selenite into organic selenium and Se0. In this paper, label-free quantitative proteomics was applied to explore the mechanism of salt stress promoting selenium enrichment of L.rhamnosus. 397 proteins were up-regulated and 147 proteins were down-regulated of se...

TranscriptomicsTranscription profiling of Arabidopsis roots and shoots from plants grown on selenate
Selenate is chemically similar to sulfate and can be taken up and assimilated by plants via the same transporters and enzymes. In contrast to many other organisms, selenium (Se) has not been shown to be essential for higher plants. In excess, Se is toxic and restricts development. Both Se deficie...

ProteomicsComparative proteomic analysis of pepper (Capsicum annuum L.) seedlings under selenium stress
Selenium (Se) is an essential trace element for human and animal health. Se fertilizer has been used to increase the Se content in crops to meet the Se requirements in humans and animals. To address the challenge of Se poisoning in plants, the mechanisms underlying Se-induced stress in plants must b...
