Abstract
Selenium-rich rice has become one of the effective ways to increase people's selenium intake. Selenium-containing proteins have higher antioxidant properties, which may lead to selenium-rich brown rice (Se-BR) having better storage stability than ordinary brown rice (BR). By measuring the peroxidation value, fatty acid value, carbonyl value and protein secondary structure, it was found that Se-BR had higher oxidation resistance stability than BR. The biological function of the differential proteins (DEPs) between ordinary brown rice stored for 0 days (BR-0) and 180 days (BR-6) as well as Se-rich brown rice stored for 0 days (Se-0) and 180 days (Se-6) was investigated by using iTRAQ. A total of 237, 235, 113 and 213 DEPs were identified from group A (BR-0/BR-6), group B (Se-0/Se-6), group C (BR-0/Se-0) and group D (BR-6/Se-6), respectively. Kyoto Encyclopedia of Genes and Genomes analysis showed that the DEPs were mainly enriched in glucose metabolism, tricarboxylic acid cycle, fatty acid biosynthesis and degradation, glutathione metabolism, sulfur metabolism, peroxisome and other metabolic pathways. This study provides theoretical support for the study of protein oxidation kinetics and storage quality control of brown rice during storage.

Abstract
Selenium (Se) deficiency can cause many diseases and thereby affect human health. Traditional inorganic Se supplements have disadvantages of toxicity and low bioavailability. Se-Enriched proteins exhibit good bio-accessibility and high biological activities. This review provides a comprehensive overview of the preparation, purification, identification, bioavailability, bioactivities and application of Se-enriched proteins. The method of extracting Se-enriched proteins from animals, microorganisms and plants mainly includes solvent extraction (water, salt, ethanol and alkali solution extraction) and novel extraction technologies (ultrasound-assisted and pulsed electric field assisted extraction). Se-Enriched proteins and their hydrolysates exhibit good bioactivities, mainly including antioxidant activity, immune regulation, neuroprotective activity, and inhibition of hyperglycemic activity, among others. Future research should focus on the relationship between Se-enriched protein metabolism and the selenium regulatory protein metabolic pathway by using multi-omics technology. In addition, it is necessary to comprehensively study the structure-activity relationship of Se-enriched proteins/hydrolysates from different sources, to further clarify their bioactive mechanism and to verify their health benefits in vivo.

Abstract
Our previous study has evaluated the antioxidant capacity and identified the sequences of soybean selenium-containing peptides. Herein, pharmacophore screening, gastrointestinal simulation and in vivo pharmacokinetics were performed to predict the potentials of selenium-containing peptides in terms of antioxidant activity, safety and bioavailability. A pharmacophore model with 6 structure features was constructed for virtual screening to determine the potential activities of 85 selenium sequences from soybean peptides. Strong reversing effects (p < 0.05) of the targeted sequences were observed in tumor necrosis factor-α (TNF-α)-induced inflammatory cytokines and adhesion factors burst in EA·hy926/Caco-2 co-culture cell models. Ser-Phe-Gln-SeMet (SFQSeM), a promising peptide selected from both virtual screening and cell models, was proved to be stable in the gastrointestinal tract and could be transported across the Caco-2 monolayer via the paracellular pathway. Additionally, SFQSeM showed a long residence time (89.42 ± 1.34 min) and half-life (81.60 ± 11.88 min) after consumption, and it induced lower liver alanine/aspartate transaminase (ALT/AST) and serum nitric oxide (NO) levels compared to Na2SeO3 and SeMet (p < 0.05). The potency of SFQSeM against oxidative stress as well as its oral bioavailability and low risk highlight its potential utility as an effective Se nutritional supplement.

Abstract
Selenium (Se) is an essential nutrient associated with several physiological processes in humans and has raised interest because of its antioxidant and immune properties. Se deficiency is related to a variety of diseases and dysfunctions in humans. Due to its higher bioavailability and lower toxicity, organic Se is more recommendable than inorganic Se in the frame of a balanced diet. Se is present in 25 identified selenoproteins that commonly occur in human organisms. As part of selenocysteine (SeC), Se becomes co-translationally incorporated into the polypeptide chain and involved in the regulation of oxidative stress, redox mechanisms, and other crucial cellular processes responsible for innate and adaptive immune responses. This review presents the current information regarding the presence of selenoproteins in the human body, and the separation of selenoproteins and selenopeptides from various plants and their physiological roles in the immune and oxidation systems of humans. In general, the application of selenoproteins and Se-enriched peptides are practically important for the clinical arena, whereby it can be used for exploring new healthy foods.

Abstract
Selenium is an essential microelement required for biological processes. Traditional selenium supplements (selenite and selenomethionine mainly) remain concerns due to toxicity and bioavailability. In recent decades, biofortification strategies have been applied to produce selenium-enriched edible plants to address the challenges of superior nutritional quality requirements. Plant-derived selenium-containing proteins/peptides offer potential health benefits beyond the basic nutritional requirements of Se. Highly nucleophilic seleno-amino acids, special peptide sequences, and favorable bioavailability contribute to the biological activities of selenium-containing proteins/peptides, such as antioxidant, antihypertensive, anti-inflammatory, and immunomodulatory effects. However, their applications on a commercial scale are insufficient owing to the complexity of purification and identification techniques and the sparse information on bioavailability and metabolism. In this review, selenium status, structural features, bioactivities, structure-activity relationships, and bioavailability, as well as the mechanisms underlying the bioactivities and metabolism of plant-derived selenium-containing proteins/peptides, are summarized and discussed for their nutraceutical use.

Abstract
Selenium (Se) is an essential micronutrient for human health. Deficiency and suboptimality of Se in human populations are a potential health risk. The reduction of such health risk by biofortification of crops, particularly in wheat has drawn much attention, especially for color-grained wheat as it is rich in anthocyanins and can be used as a major source of antioxidants in diet. Herein, a two-year field study on the purple-grained wheat cultivar (202w17) and common wheat cultivar (Shannong 129) was conducted with soil application (SeS) and foliar spray (SeF) of selenium. Results showed that the SeS increased shoot dry weight and grain yield. Both SeS and SeF enhanced the concentration of organic Se, but the higher concentration of organic Se in the grain of two cultivars was observed in SeF in comparison with SeS. The concentration of organic Se in the grain of 202w17 treated with SeF was approximately 1.5-fold of that in Shannong 129 with SeF. The analysis of Se accumulation in different parts of the plant revealed that 202w17 accumulated more Se in shoots and grain than Shannong 129, and 202w17 had also higher levels of total protein, total free amino acids and anthocyanin in grain than Shannong 129. In addition, SeF significantly increased the concentrations of zinc (Zn), calcium (Ca), magnesium (Mg) in both cultivars, but decreased the concentration of chromium (Cr), cadmium (Cd) and lead (Pd), which phenomenon was more significant in 202w17. Our results indicate that SeS increases plant growth, leading to higher grain yield in two cultivars tested. The purple-grained wheat (202w17) could accumulate more Se in grain and have a higher concentration of orgainic Se in grain than the common wheat (Shannong 129).

Abstract
Proteins were extracted from Se-enriched peanut leaves, an agro-byproduct, and the foliar application of sodium selenite was indicated to be an effective method to incorporate Se into leaf selenoproteins with 75-80% incorporation rates. After trypsin digestion, the most abundant proteins from Se-enriched peanut leaf (PSPL) were identified as pathogenesis-related class 10 proteins, Ara h 8 allergen and its isoforms, using LC-MS/MS. The Se species in both the low Se PSPL and high Se PSPL were determined to be selenomethionine (SeMet), methylselenocysteine (MeSeCys) and selenocystine (SeCys2) with SeMet (15.6 mg/g) dominated the high Se PSPL. Their antioxidant activities were also evaluated using free radical scavenging assay, reducing power assay and ferric thiocyanate (FTC) test. As results, the PSPL exhibited potent DPPH radical (96.2%) and superoxide anion radical (98.4%) scavenging activities and showed strong reducing power in a Se-concentration-dependent manner, indicating that PSPL can be used as antioxidants and Se sources to improve health.

Abstract
The oxidative activities of hydroponically produced Chinese kale (Brassica oleracea var. alboglabra L.) seedlings grown under different concentrations of selenium (Se) biofortification with sodium selenite (Na2SeO3) at 0, 5, 10, 15, and 30 mg·Se/L and different ages (5, 10, and 15 days after germination) were determined by the electron transfer method (DPPH and FTC). Highest antioxidant activities of Se-enriched Chinese kale seedlings (Se-KS) were found in seedlings grown on 30 mg·Se/L, 15 days after germination. The physicochemical contents (moisture, crude fibre, ash, crude protein, and carbohydrate), total Se contents, and Se bioaccessibility and antioxidant activities (after treatment with an in vitro simulated gastrointestinal digestion process) between Se-KS and a control of regular Chinese kale seedlings (R-KS) were compared. The crude protein and total Se contents of the air-dried matter in Se-KS were higher (37 ± 1% and 433 ± 22 mg·Se/kg) than those of the R-KS (33 ± 2% and 17 ± 3 mg·Se/kg). Total Se content and antioxidant activities were strongly correlated in the range from 0.93 to 0.99. Testing acute toxicity, a single dose of the Se-KS was orally administrated to rats at 1250, 2500, and 5000 mg/kg·b.w., which consisted of 0.54, 1.08, and 2.16 mg Se/kg·b.w., respectively. These results demonstrated that Se-KS did not create any toxicological signs and mortality. No abnormal pathological changes in the liver, kidney, and heart were found. The results suggested that the Se-KS could be a good source of organo Se for development as a new Se supplementary product.

Abstract
The relationship between hepatoprotective effects of selenium-biofortified corn (Zea mays Linn) peptides (SeCPs) and its antioxidant ability was evaluated and the structure of SeCPs was identified. SeCPs and corn peptides (CPs) both had good antioxidant ability, and the effect of SeCPs was significantly higher than CPs within a certain concentration range (P < 0.05). Additionally, animal experiments indicated that SeCPs (200 mg/kg) had a significantly protective effect against concanavalin A (Con A) induced hepatic lesions, as it significantly declined glutamic-pyruvic transaminase (AST), alanine transaminase (ALT) activities, tumor necrosis factor alpha (TNF-α), interferon (IFN)-γ contents in serum, and malondialdehyde (MDA) contents in liver (P < 0.05). Superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities in liver were also significantly increased by SeCPs (P < 0.05). The amino acid composition of SeCPs with Mw < 1 kDa was mainly glutamic acid (Glu, 31.18%), leucine (Leu, 21.06%) and alanine (Ala, 13.26%). According to the retention time, the amino acid sequences of 8 selenium-biofortified corn peptides and 29 selenium-free corn peptides were identified. Our results illustrated that the mechanisms of SeCPs against Con A induced hepatic injury in mice may be related to its antioxidant ability and reduction of lipid peroxidation, inhibiting the release of immune factors, such as TNF-α and IFN-γ.

Abstract
BACKGROUND Enteric dysbiosis is associated with chronic inflammation and interacts with obesity and insulin resistance. Obesity and diabetes are induced in ICR (Institute of Cancer Research) mice fed a high-fat diet and administered a streptozocin injection. These mice were treated with normal rice (NR), normal rice with a high resistant starch content (NRRS) or Se-rich rice (selenium-enriched rice) with a high resistant starch content (SRRS). RESULTS Faecal cell counts of Bifidobacterium, Lactobacillus and Enterococcus were significantly higher in SRRS-treated mice than in diabetic controls, while Enterobacter cloacae were lower. Similar results were also found in NRRS-treated mice. In contrast, no significant difference was found between NR-treated and diabetic control groups. The treatments with SRRS and NRRS reduced the faecal pH values of the diabetic mice. Regarding the inflammatory factor levels, lower levels of serum C-reactive protein (CRP), tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6), nuclear factor-k-gene binding (NF-κB) and leptin (LEP) and higher adiponutrin (ADPN) levels were found in the SRRS and NRRS-treated mice compared with the diabetic and NR-treated mice. In addition, the CRP, IL-6 and NF-κB levels in the SRRS-treated mice were significantly reduced compared with those observed in the NRRS-treated mice. The reverse transcription-PCR (RT-PCR) results showed that the SRRS and NRRS-treated mice presented higher expression levels of orphan G protein-coupled receptor 41 (GPR41) and orphan G protein-coupled receptor 43 (GPR43) proteins compared with diabetic mice and NR-treated mice. CONCLUSION These results indicate that treatments with rice high in RS exert beneficial effects by improving enteric dysbiosis and chronic inflammation. In addition, selenium and RS may exert synergistic effects on chronic inflammation. © 2016 Society of Chemical Industry.

Abstract
We evaluated the effects of selenium (Se) on antioxidant enzymes of piglet splenic lymphocytes exposed to deoxynivalenol (DON). We measured cell viability, the activities of several antioxidant enzymes, and lactate dehydrogenase (LDH), as well as total antioxidant capacity (T-AOC) and the levels of malonaldehyde (MDA) and hydrogen peroxide (H2O2). We found that DON exposure increased the concentrations of LDH, MDA, and H2O2 in all experimental groups in a dose-dependent manner, while the concentrations of other antioxidant enzymes were decreased. In Se-pretreated DON-exposed cells, damage to antioxidant enzymes was reduced, especially in the lower-dose DON groups over longer exposure times. These results may indicate that in piglet splenic lymphocytes, Se can alleviate DON-induced damage to antioxidant enzymes by improving glutathione peroxidase activity. Se may function as a potential antioxidative agent to alleviate DON-induced oxidative stress.

JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2015; 95:1544-1553. [PMID: 25087732 DOI: 10.1002/jsfa.6859] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/09/2014] [Revised: 07/25/2014] [Accepted: 07/28/2014] [Indexed: 06/03/2023]
Abstract
BACKGROUND The immune system is important in preventing and controlling various infectious diseases. Immunoactive peptides derived from food proteins could exert immunomodulatory activity without side effects. Paphia undulata with high-protein is suitable for the production of immunoactive peptides. The objective of this study was to optimize the hydrolysis parameters to maximize the immune activity of hydrolysates from Paphia undulata. RESULTS Hydrolysis parameters, including temperature, time and the ratio of alkaline protease to Paphia undulata meat (E/S), were optimized by response surface methodology with a central composite design. The optimum conditions were obtained as follows: temperature, 51 °C; time, 3.14 h; E/S, 4,321 U g(-1) (Paphia undulata meat). Furthermore, hydrolysates obtained under the optimum conditions were fractionated by ultrafiltration and gel filtration on a Sephadex G-25 column. After two-step isolation, the isolated fractions (P2 and P3) including the peptides Pro-His-Thr-Cys, Val-Gly-Try-Thr, Glu-Phe, Leu-Phe, and Glu-Gly-Ala-Lys, Trp-Ile or Trp-Leu, respectively, could significantly enhance lymphocyte proliferation ability. CONCLUSION These results showed that response surface methodology and two-step separation were efficient for recovery of low-molecular-weight peptides with high spleen lymphocyte proliferation activity, and the isolated fractions of Paphia undulata hydrolysates are potential ingredients for development of functional foods.

Abstract
A study to compare the uptake, translocation, and distribution of selenium (Se) in soybean planted in natural seleniferous soil in Fengcheng city of China was conducted to clarify the relationship between the Se content levels of soybean proteins and their radical scavenging activity. The data showed that the total Se content in different parts of soybean plants varied with the growth periods. The selenoprotein (Se-SPI) content increased remarkably with the increase of Se content in seleniferous soils. The Se-SPI content obtained from the region with the highest Se level was almost 18 times higher than that of the control group, while antioxidant activities were about 4-fold compared to the control, suggesting that Se played a positive role in enhancing the antioxidant activity of Se-SPI. The increase in the Se level also led to changes in amino acids composition, but with nearly no effects on the subunit composition of soybean Se-SPI.

Abstract
A method has been developed for a rapid and precise location of selenium-containing proteins in large two-dimensional (2D) electrophoresis gels. A sample was divided into four aliquots which were analyzed in parallel by 1D isoelectric focusing electrophoresis (IEF)-laser ablation (LA) inductively coupled plasma mass spectrometry (ICP MS), 1D sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE)-LA ICP MS, and, in duplicate, by 2D IEF-PAGE. On the basis of the 1 D electropherograms obtained, areas supposed to contain the largest concentrations of Se were subjected to LA ICP MS imaging to locate precisely the position of Se-containing proteins which were then identified in the parallel 2D gel by electrospray Orbitrap MS/MS. The method was applied to the identification and semiquantitative determination of selenium storage proteins in wheat. MS evidence is presented for the Se-S substitution in plants not only in methionine but also in cysteine.
