ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2024; 357:124448. [PMID: 38942272 DOI: 10.1016/j.envpol.2024.124448] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2024] [Revised: 06/21/2024] [Accepted: 06/25/2024] [Indexed: 06/30/2024]
Abstract
Mercuric chloride (HgCl2) is a widespread inorganic mercury with digestive toxicity. The pancreas is an important digestive organ in animals, and pancreatic fibrosis (PF) is a major pathological feature of chronic pancreatitis, which can be caused by heavy metals. Selenium (Se) is an essential trace element for the animal organism, performing biological functions in the form of selenoproteins, as well as alleviating the toxicity of heavy metals. In this study, we explored the specific mechanisms underlying the protective effect of Se on HgCl2-induced pancreatic injury in chickens. Morphological observation and serum biochemical analysis showed that Se attenuated HgCl2-caused pancreatic tissue damage and elevated glucose concentration and α-amylase activity. Next, the expression of oxidative stress indicators such as MDA and GSH-Px as well as inflammation-related markers including IL-1β, IL-6, and TNF-α were detected. Results showed that Se had an inhibitory effect on HgCl2-induced oxidative stress and inflammation. Furthermore, we found that Se alleviated HgCl2-induced PF by detecting the expression of markers related to PF including TGF-β1, α-SMA, COL1A1, and FN1. Mechanistically, Se attenuated HgCl2-induced PF via the MAPK signaling pathway. Importantly, several selenoproteins, especially those with antioxidant activity, were involved in the protective effect of Se on HgCl2 toxicity. In conclusion, our findings demonstrated that Se inhibited HgCl2-induced oxidative stress and inflammation and alleviated chicken PF through the MAPK signaling pathway, in which some antioxidant selenoproteins were involved.

Abstract
Selenium (Se) deficiency is associated with the development of Keshan disease, a cardiomyopathy associated with massive cardiac immune cell infiltration that can lead to heart failure (HF). The purpose of this study was to determine whether high Se diet can attenuate systolic overload-induced cardiopulmonary inflammation and HF. Briefly, transverse aortic constriction (TAC)-induced cardiopulmonary oxidative stress, inflammation, left ventricular (LV) dysfunction, and pulmonary remodeling were determined in male mice fed with either high Se diet or normal Se diet. High Se diet had no detectable effect on LV structure and function in mice under control conditions, but high Se diet significantly protected mice from TAC-induced LV hypertrophy, dysfunction, increase of lung weight, and right ventricular hypertrophy. As compared with mice treated with normal Se diet, high Se diet also reduced TAC-induced LV cardiomyocyte hypertrophy, fibrosis, leukocyte infiltration, pulmonary inflammation, pulmonary fibrosis, and pulmonary micro-vessel muscularization. In addition, high Se diet significantly ameliorated TAC-induced accumulation and activation of pulmonary F4/80+ macrophages, and activation of dendritic cells. Interestingly, high Se diet also significantly attenuated TAC-induced activation of pulmonary CD4+ and CD8+ T cells. Moreover, we found that TAC caused a significant increase in cardiac and pulmonary ROS production, increases of 4-hydroxynonenal (4-HNE) and 3-nitrotyrosine (3-NT), as well as a compensatory increases of LV glutathione peroxidase 1 (GPX1) and 4 (GPX4) in mice fed with normal Se diet. Above changes were diminished in mice fed with high Se diet. Collectively, these data demonstrated that high Se diet significantly attenuated systolic pressure overload-induced cardiac oxidative stress, inflammation, HF development, and consequent pulmonary inflammation and remodeling.

J Comp Physiol B 2024:10.1007/s00360-024-01578-w. [PMID: 39158728 DOI: 10.1007/s00360-024-01578-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2024] [Revised: 07/13/2024] [Accepted: 08/02/2024] [Indexed: 08/20/2024]
Abstract
The current research was conducted to assess the effect of in ovo feeding (IOF) of selenium (Se) and zinc (Zn) on hatchability, production performance, liver, intestinal morphology, antioxidant levels and expression levels of immune-related genes in broiler chickens. A total of 400 fertilized eggs were equally divided into four groups: control (non-injected), sham (in ovo injection of 0.75% NaCl), Se (@ 1.5 µg/egg in ovo injection) and Zn (500 µg/egg in ovo injection) groups respectively. On the seventeenth day of incubation, treatment solutions were administered into amniotic fluid of fertilized eggs. The results revealed that Se and Zn supplementation significantly (P < 0.05) enhanced hatchability, post-hatch growth, organ development, and liver antioxidant capability. Histopathological examination revealed a typical hepatocyte morphology, well-arranged cells, and a significant (P < 0.05) decrease in apoptosis in both selenium and zinc groups. Additionally, selenium and zinc produced auspicious effects on intestinal epithelium and villi surface area. Interestingly, our results revealed that IOF of Se and Zn modulated the expression of immune-related genes in comparison to the control and sham groups. Conclusively, IOF of Se and Zn augmented health and productivity by enhancing the cellular immunity in the broiler chickens, thus IOF can be utilized as an effective strategy to promote health and immunity in broiler chickens.

Abstract
Micronutrients (MN), i.e. trace elements and vitamins, are essential organic molecules, which are required in the diet in relatively small amounts in any form of nutrition (oral, enteral, parenteral). The probability of MN depletion or deficiencies should be considered in all chronic illnesses, especially in those that can interfere with intake, digestion, or intestinal absorption. Low socio-economic status and food deprivation are recognized as the most prevalent reasons for MN deficiencies world-wide. Elderly multimorbid patients with multimodal therapy, as well as patients with long-lasting menu restrictions, are at high risk for both disease related malnutrition as well as multiple MN deficiencies, needing careful specific follow-up. The importance of monitoring MN blood levels along with CRP is essential for optimal care. Drug interactions are also highlighted. In patients with chronic conditions depending on medical nutrition therapy, the provision of adequate dietary reference intakes (DRI) of MN doses and monitoring of their adequacy belongs to standard of care.

Abstract
OBJECTIVE Otitis media with effusion (OME) is a prevalent and costly disease, especially in children. This article analyzed the expression patterns and clinical significance of T helper-1 (Th1)/Th2 cytokines in the peripheral blood of children with OME and allergic rhinitis (AR). METHODS Subjects were assigned to the OME + AR group and the Control group (children with OME), with their clinical baseline data documented. The correlations between Th1/Th2 cytokines and between the total nasal symptom score (TNSS) and Th1/Th2 cytokines were analyzed. The risk factors and the predictive value of Th1/Th2 cytokines for OME + AR were analyzed using logistics multivariate regression analysis and receiver operating characteristic curve. RESULTS Significant differences were observed in tympanic pressure/speech frequency/air conduction valve/TNSS score/immunoglobulin E (IgE) level between both groups. The OME + AR children exhibited evidently elevated interleukin-2 (IL-2)/tumor necrosis factor-α (TNF-α)/IL-4/IL-10/IL-6 levels and no significant difference in interferon-γ (IFN-γ) level. Th1/Th2 cytokines were remarkably positively-correlated with the TNSS score. IL-2/TNF-α/IL-4/IL-6 were risk factors for OME with AR. The area under the curves (AUCs) of IL-6/IL-2/IL-4/TNF-α levels in predicting the occurrence of OME + AR were 0.805/0.806/0.775/0.781, with sensitivities of 75.76 %/89.39 %/72.21 %/72.73 % and specificities of 74.29 %/61.34 %/72.86 %/70.00 %, and the cut-off values were 239.600/20.300/29.880/34.800 (pg/mL). The AUC of their combination in predicting OME + AR was 0.955 (93.94 % sensitivity, 85.71 % specificity). CONCLUSION Th1/Th2 cytokine levels were imbalanced and obviously positively-correlated with the TNSS score in OME + AR children. IL-2, TNF-α, IL-4, and IL-6 levels had auxiliary predictive value in the occurrence of OME + AR.

Abstract
T cells are crucial for adaptive immunity to regulate proper immune response and immune homeostasis. T cell development occurs in the thymus and mainly differentiates into CD4+ and CD8+ T cell subsets. Upon stimulation, naive T cells differentiate into distinct CD4+ helper and CD8+ cytotoxic T cells, which mediate immunity homeostasis and defend against pathogens or tumours. Trace elements are minimal yet essential components of human body that cannot be overlooked, and they participate in enzyme activation, DNA synthesis, antioxidant defence, hormone production, etc. Moreover, trace elements are particularly involved in immune regulations. Here, we have summarized the roles of eight essential trace elements (iron, zinc, selenium, copper, iodine, chromium, molybdenum, cobalt) in T cell development, activation and differentiation, and immune response, which provides significant insights into developing novel approaches to modulate immunoregulation and immunotherapy.

Abstract
Bisphenol A (BPA) is a ubiquitous environmental pollutant that can have harmful effects on human and animal immune systems by inducing oxidative stress. Selenium (Se) deficiency damages immune organ tissues and exhibits synergistic effects on the toxicity of environmental pollutants. However, oxidative stress, cell apoptosis, and autophagy caused by the combination of BPA and low-Se, have not been studied in the bursa of Fabricius of the immune organ of poultry. Therefore, in this study, BPA and/or low-Se broiler models and chicken lymphoma cells (MDCC-MSB-1 cells) models were established to investigate the effects of BPA and/or low-Se on the bursa of Fabricius of poultry. The data showed that BPA and/or low-Se disrupted the normal structure of the bursa of Fabricius, BPA (60 μM) significantly reduced the activity of MDCC-MSB-1 cells and disrupted normal morphology (IC50 = 192.5 ± 1.026 μM). Compared with the Control group, apoptosis and autophagy were increased in the BPA or low-Se groups, and the generation of reactive oxygen species (ROS) was increased. This inhibited the AKT/FOXO1 pathway, leading to mitochondrial fusion/division imbalance (Mfn1, Mfn2, OPA1 were increased, DRP1 was decreased) and dysfunction (CI-NDUFB8, CII-SDHB, CIII-UQCRC2, CIV-MTCO1, CV-ATP5A1, ATP). Furthermore, combined exposure of BPA and low-Se aggravated the above-mentioned changes. Treatment with N-acetylcysteine (NAC) reduced ROS levels and activated the AKT/FOXO1 pathway to further alleviate BPA and low-Se-induced apoptosis and autophagy. Apoptosis induced by low-Se + BPA was exacerbated after 3-Methyladenine (3-MA, autophagy inhibitor) treatment. Together, these results indicated that BPA and low-Se aggravated apoptosis and autophagy of the bursa of Fabricius in chickens by regulating the ROS/AKT/FOXO1 pathway.

Abstract
Mycoplasma synovium (MS) is a prominent avian pathogen known to elicit robust inflammatory responses in birds while evading immune detection, often leading to chronic infection and immune compromise. The mechanisms underpinning MS-mediated splenic tissue damage in chickens, however, remain undefined. In our investigation with 7-day-old SPF chickens, we administered an MS-Y bacterial solution (200 µl, 1 × 109 CCU/ml) through eye and nose droplets, collecting spleen samples on days 3, 6, and 12 post-infection. Comprehensive analyses utilizing histopathology, electron microscopy, TUNEL assay, qRT-PCR, and western blot were employed. Results demonstrated that MS-infection downregulated T-SOD, GSH-PX, and CAT, while concurrently elevating iNOS, NO, and MDA levels. Evidently, MS-induced oxidative stress compromised the spleen's antioxidant defences. Histological examinations pinpointed splenic damage characterized by lymphocyte reduction and increased inflammatory cell infiltration. Ultrastructural observations revealed clear apoptotic markers, including mitochondrial perturbations and nuclear anomalies. Importantly, MS induced significant spleen tissue apoptosis, as supported by TUNEL assay outputs and gene expression profiles associated with apoptosis. Concurrently, we observed upregulated expressions of mRNAs and proteins affiliated with the NF-κB/MAPK signalling cascade (p < 0.05). Collectively, our data elucidate that MS infection induces splenic apoptosis and oxidative disturbances, perturbs tissue integrity, and potentiates the NF-κB/MAPK-mediated inflammatory cascade.

Abstract
Selenium (Se) is an essential trace element that plays an important role in thyroid physiology. Se supplementation can reduce levels of autoimmune thyroid antibodies, which may be beneficial in Hashimoto's thyroiditis (HT). However, the long-term benefits of Se supplementation for HT patients are controversial and there is no clear clinical evidence to support it, so further basic and clinical research is needed. The effect of Se on immune cells, especially T cells, in autoimmune thyroiditis (AIT) has not been elucidated. Here, we replicated a mouse model of experimental autoimmune thyroiditis (EAT) on a high-iodine diet and treated it with Se supplementation. At week 8 of the experiment, Se supplementation reduced the destruction of thyroid follicles and the infiltration rate of lymphocytes in EAT mice, and reversed the disturbance of peripheral blood thyroxine and thyroid autoantibody levels. Further examination revealed that Se had broad effects on T-cell subsets. Its effects include reducing the production of pro-inflammatory cytokines by Th1 cells, inhibiting the differentiation and production of cytokines by Th2 and Th17 cells, and upregulating the differentiation and production of cytokines by Treg cells. These changes help alleviate thyroid follicle damage during EAT. In conclusion, selenium supplementation has the potential to improve the prognosis of AIT by altering the subset differentiation and/or function of CD4+ T cells.

Abstract
BACKGROUND Selenium metabolism has been implicated in human health. This study aimed to identify a selenium metabolism regulator-based prognostic signature for hepatocellular carcinoma (HCC) and validate the role of INMT in HCC. METHODS Transcriptome sequencing data and clinical information related to selenium metabolism regulators in TCGA liver cancer dataset were analysed. Next, a selenium metabolism model was constructed by multiple machine learning algorithms, including univariate, least absolute shrinkage and selection operator, and multivariate Cox regression analyses. Then, the potential of this model for predicting the immune landscape of different risk groups was evaluated. Finally, INMT expression was examined in different datasets. After knockdown of INMT, cell proliferation and colony formation assays were conducted. RESULTS A selenium metabolism model containing INMT and SEPSECS was established and shown to be an independent predictor of prognosis. The survival time of low-risk patients was significantly longer than that of high-risk patients. These two groups had different immune environments. In different datasets, including TCGA, GEO, and our PUMCH dataset, INMT was significantly downregulated in HCC tissues. Moreover, knockdown of INMT significantly promoted HCC cell proliferation. CONCLUSIONS The current study established a risk signature of selenium metabolism regulators for predicting the prognosis of HCC patients. INMT was identified as a biomarker for poor prognosis of HCC.

Abstract
BACKGROUND Selenium (Se) deficiency is a recognized problem that threatens the health of people worldwide, and wheat is grown worldwide and is one of the major sources of dietary Se. Since there are few studies that have investigated the changes in Se content and speciation of different varieties of Se-enriched wheat from primary to deep processing, we studied four naturally Se-enriched kinds of wheat and two Se-fertilized kinds of wheat. RESULTS Glutenin- and albumin-bound Se accounted for the highest proportion of protein-bound Se in refined wheat flour (7.29 ± 0.19 to 10.82 ± 0.50% and 6.16 ± 0.34 to 8.45 ± 0.07%); water-soluble polysaccharide-bound Se accounted for the highest proportion of polysaccharide-bound Se in refined wheat flour (12.02 ± 0.54 to 24.62 ± 1.87%). Coarse bran Se content was significantly higher than refined wheat flour (137.94 ± 7.80 to 174.55 ± 5.09% for unpeeled wheat, 147.27 ± 10.96 to 187.72 ± 17.70% for peeled wheat). The peeling and processing of wheat into flour had different effects on Se the content and speciation dependent on the particular wheat variety. Whole wheat flour enabled better retention of selenomethionine (101.64 ± 2.32 to 138.41 ± 2.84% for unpeeled wheat, 158.59 ± 13.72 to 250.20 ± 4.94% for peeled wheat). The cooking process had no significant effect on Se content, but Se species were possibly interconverted. CONCLUSION The organic Se content of different varieties of Se-enriched wheat was different, but the milling and cooking process retained the total Se and Se speciation better, which could be used for daily Se supplementation for Se-deficient people. © 2022 Society of Chemical Industry.

Abstract
Selenium deficiency can affect the level of selenoprotein in organs and tissues and cause inflammation. However, the mechanism of selenium deficiency on jejunal injury in chickens remains unclear. In this study, we established a selenium deficiency model in chickens by feeding a low selenium diet and observed ultrastructural and pathological changes in the jejunum. The expression levels of 25 selenoproteins, the levels of oxidative stress, tight junction (TJ) proteins, and antimicrobial peptides (AMP), as well as the expression levels of factors related to inflammatory signaling pathways, were examined in the intestine and analyzed using principal component analysis (PCA). The results of PCA and quantitative real-time PCR (qRT-PCR) showed that selenium deficiency mainly affected the expression of antioxidant selenoproteins in chicken jejunum, especially glutathione peroxidases, thioredoxin reductase, and iodothyronine deiodinase, thus weakening the antioxidant function in the intestine and inducing oxidative stress. We also found disruption of intestinal TJ structures, a significant reduction in TJ protein expression, and downregulation of antimicrobial peptide levels, suggesting that selenium deficiency led to damage of the intestinal barrier. In addition, a significant increase in inflammatory cell infiltration and expression of inflammatory factors was observed in the jejunum, indicating that selenium deficiency induces inflammatory injury. In conclusion, selenium deficiency downregulates antioxidant selenoproteins levels, induces oxidative stress, decreases intestinal AMP levels, and leads to inflammatory injury and disruption of the intestinal barrier in the jejunum. These results shed new light on the molecular mechanisms of intestinal damage caused by selenium deficiency.

Abstract
Selenium-enriched black soybean protein (SeBSP) is a kind of high-quality selenium resource with many physiological functions. Benzo(a)pyrene (BaP) is a well-known injurant that widely exists in high-temperature processed food and has been previously found to cause colon injury. In this study, the effects of SeBSP on colonic damage induced by BaP in BALB/C mice were investigated by comparing it with normal black soybean protein (BSP). SeBSP inhibited the BaP-induced reductions on body weight, food intake, and water intake. Moreover, metabolic enzymes, including AhR, CYP1A1, CYP1B1, and GST-P1, that were promoted by BaP were downregulated by SeBSP, reducing oxidative damage caused by BaP in the metabolic process. The classical pyroptosis indexes (i.e., NLRP3, ASC, Caspase-1, GSDMD) and inflammatory factors (i.e., TNF-α, IL-1β, IL-18, iNOS, COX-2) were downregulated by SeBSP in BaP-treated mice, suggesting the benefits of SeBSP in reducing colonic toxicity. Notably, SeBSP enhanced microbial diversity of gut microbiota and increased relative abundances of prebiotic bacteria, for example, Lactobacillus reuteri, Bacteroides thetaiotaomicron, and genera Bifidobacterium, and Blautia, along with the promotion of short-chain fatty acids. Integrative analysis showed strong links between the antioxidant and anti-inflammatory effects of SeBSP and its altered gut microbiota. Collectively, our study demonstrates the pronounced benefits of Se-enriched black soybean in preventing the colonic toxicity of BaP, and such effects could be mediated by gut microbiota.

Abstract
Selenium (Se) is an essential micronutrient that functions in the body mainly in the form of selenoproteins. The selenoprotein contains 25 members in humans that exhibit a number of functions. Selenoproteins have immunomodulatory functions and can enhance the ability of immune system to regulate in a variety of ways, which can have a preventive effect on immune-related diseases. Food allergy is a specific immune response that has been increasing in number in recent years, significantly reducing the quality of life and posing a major threat to human health. In this review, we summarize the current understanding of the role of Se and selenoproteins in regulating the immune system and how dysregulation of these processes may lead to food allergies. Thus, we can explain the mechanism by which Se and selenoproteins boost immunity to prevent food allergies.

Abstract
Current chemotherapy strategies used in clinic appear with lots of disadvantages due to the low targeting effects of drugs and strong side effects, which significantly restricts the drug potency, causes multiple dysfunctions in the body, and even drives the emergence of diseases. Immunotherapy has been proved to boost the body’s innate and adaptive defenses for more effective disease control and treatment. As a trace element, selenium plays vital roles in human health by regulating the antioxidant defense, enzyme activity, and immune response through various specific pathways. Profiting from novel nanotechnology, selenium nanoparticles have been widely developed to reveal great potential in anticancer, antibacterial, and anti-inflammation treatments. More interestingly, increasing evidence has also shown that functional selenium nanoparticles can be applied for potential immunotherapy, which would achieve more effective treatment efficiency as adjunctive therapy strategies for the current chemotherapy. By directly interacting with innate immune cells, such as macrophages, dendritic cells, and natural killer cells, selenium nanoparticles can regulate innate immunity to intervene disease developments, which were reported to boost the anticancer, anti-infection, and anti-inflammation treatments. Moreover, selenium nanoparticles can also activate and recover different T cells for adaptive immunity regulations to enhance their cytotoxic to combat cancer cells, indicating the potential of selenium nanoparticles for potential immunotherapy strategy development. Here, aiming to enhance our understanding of the potential immunotherapy strategy development based on Se NPs, this review will summarize the immunological regulation effects of selenium nanoparticles and the application of selenium nanoparticle-based immunotherapy strategies. Furthermore, we will discuss the advancing perspective of selenium nanoparticle-based potential immunotherapy as a kind of novel adjunctive therapy to enhance the efficiency of current chemotherapies and also introduce the current obstacles for the development of selenium nanoparticles for potential immunotherapy strategy development. This work is expected to promote the future research on selenium nanoparticle-assisted immunotherapy and finally benefit the more effective disease treatments against the threatening cancer and infectious and chronic diseases.

Abstract
This study was performed to investigate the immune enhancement effect of glycine nano-selenium, a microelement on H9N2 avian influenza virus vaccine (H9N2 AIV vaccine) in mice. Fifty (50) Specific Pathogen Free Kunming mice aged 4−6 weeks (18−20 g Body weight) were randomly divided into five groups: control normal group, which received no immunization + 0.5 mL 0.9% normal saline, positive control group, which received H9N2 AIV vaccine + 0.5 mL 0.9% normal saline, 0.25 mg/kg selenium group, which received H9N2 AIV vaccine + 0.5 mL 0.25 mg/kg selenium solution, 0.5 mg/kg selenium group, which received H9N2 AIV vaccine + 0.5 mL 0.5 mg/kg selenium solution, and 1 mg/kg selenium group, which received H9N2 AIV vaccine + 0.5 mL 1 mg/kg selenium solution. Hematoxylin and eosin staining, enzyme linked immunosorbent assay (ELISA), and quantitative real time polymerase chain reaction (qRT-PCR) methods were used to investigate the pathological changes, immunoglobulin levels, and cytokine gene expressions in this study. The results showed that all tested doses (0.25 mg/kg, 0.5 mg/kg and 1.00 mg/kg) of glycine nano-selenium did not lead to poisoning in mice. In addition, when compared to the positive control group, glycine nano-selenium increased the immunoglobin indexes (IgA, IgG, IgM and AIV-H9 IgG in serum) as well as the mRNA levels of IL-1β, IL-6 and INF-γ in the liver, lungs, and spleen (p < 0.05). In summary, glycine nano-selenium could enhance the efficacy of avian influenza vaccine.

Abstract
Selenoprotein K (SELENOK) is an endoplasmic reticulum stress (ERS)-regulated protein required for the calcium (Ca2+) flux-mediated migration of T cells and neutrophils, and the migration and phagocytosis of macrophages and microglia. However, the effect of SELENOK on the regulation of the immune function of dendritic cells (DCs), including immature DCs (imDCs) and mature DCs (mDCs), is still unclear. In this study, imDCs prepared from SELENOK knockout mice were used to evaluate the effect of SELENOK on the migration and phagocytosis of imDCs. The results showed that ERS-induced downregulation of imDCs phenotypic markers led to a reduction in Ras homolog gene family member A (RhoA)-dependent migration and enhanced Ca2+/CD205-mediated phagocytosis. SELENOK deficiency-induced upregulation of selenoprotein S (SELENOS) attenuated ERS levels in imDCs. An increase in Ca2+ levels resulted in increased migration and decreased phagocytosis with or without ERS conditions. The migration was RhoA-dependent, and Ca2+ or CD205 was associated with regulating phagocytosis in imDCs. Our study found that SELENOK is required for imDC migration and phagocytosis.

Abstract
Mercury (Hg) is a heavy metal widely distributed in ecological environment, poisoning the immune system of humans and animals. Selenium (Se) is an essential microelement and selenoproteins involved in the procedure of Se antagonizing organ toxicity induced by heavy metals. The aim of this research was to investigate the changes of gene expression profile of selenoproteins induced by mercuric chloride (HgCl2) in chicken spleen lymphocytes. We established cytotoxicity model of chicken spleen lymphocytes by HgCl2 exposure, the messenger RNA (mRNA) expression levels of 25 selenoproteins in spleen lymphocytes were analyzed by real-time quantitative PCR (qPCR), and the gene expression pattern of selenoproteins was revealed by principal component analysis (PCA). The results showed that the mRNA expression levels of 13 selenoproteins (GPX3, GPX4, TXNRD2, TXNRD3, DIO2, SELENOS, SELENON, SELENOT, SELENOO, SELENOP, SELENOP2, MSRB1, and SEPHS2) were decreased in HgCl2 treatment group, and there was strong positive correlation between these selenoproteins and component 1 as well as component 2 of the PCA. At the same time, the protein expression levels of GPX4, TXNRD1, TXNRD2, SELENOM, SELENOS, and SELENON were detected by Western blotting, which were consistent with the changes of gene expression. The results showed that the expression levels of selenoproteins were aberrant in response to HgCl2 toxicity. The information presented in this study provided clues for further research on the interaction between HgCl2 and selenoproteins, and the possible mechanism of immune organ toxicity induced by HgCl2.

Abstract
Schisandrin B (Sch B) is well-known for its antitumor effect; however, its underlying mechanism remains confusing. Our study aimed to investigate the role of selenoproteins in Sch B-induced autophagy and Th1/Th2 imbalance in Hepa1-6 cells. Hepa1-6 cells were chosen to explore the antitumor mechanism and were treated with 0, 25, 50, and 100 μM of Sch B for 24 h, respectively. We detected the inhibition rate of proliferation, transmission electron microscopy (TEM), monodansylcadaverine (MDC) staining, reactive oxygen species (ROS) level and oxidative stress-related indicators, autophagy-related genes, related Th1/Th2 cytokines, and selenoprotein mRNA expression. Moreover, the heat map, principal component analysis (PCA), and correlation analysis were used for further bioinformatics analysis. The results revealed that Sch B exhibited well-inhibited effects on Hepa1-6 cells. Subsequently, under Sch B treatment, typical autophagy characteristics were increasingly apparent, and the level of punctate MDC staining enhanced and regulated the autophagy-related genes. Overall, Sch B induced autophagy in Hepa1-6 cells. In addition, Sch B-promoted ROS accumulation eventually triggered autophagy initiation. Results of Th1 and Th2 cytokine mRNA expression indicated that Th1/Th2 immune imbalance was observed by Sch B treatment in Hepa1-6 cells. Intriguingly, Sch B downregulated the majority of selenoprotein expression. Also, the heat map results observed significant variation of autophagy-related genes, related Th1/Th2 cytokines, and selenoprotein expression in response to Sch B treatment. PCA outcome suggested the key role of Txnrd1, Txnrd3, Selp, GPX2, Dio3, and Selr with its potential interactions in ROS-mediated autophagy and Th1/Th2 imbalance of Hepa1-6 cells. In conclusion, Sch B induced ROS-mediated autophagy and Th1/Th2 imbalance in Hepa1-6 cells. More importantly, the majority of selenoproteins were intimately involved in the process of autophagy and Th1/Th2 imbalance, Txnrd3, Selp, GPX2, Dio3, and Selr had considerable impacts on the process.

Abstract
Cadmium (Cd), as a common environmental pollutant, has been reported to cause T lymphocyte dysfunction and cell apoptosis in multiple organs. However, whether subacute Cd exposure can induce apoptosis of hepatocytes and the relationship with Th1/Th2 imbalance were still unclear. In this study, ten 6-week-old piglets were selected and randomly assigned into two groups, the control group and the Cd group. The control group was fed with the standard diet, and for the Cd group, the standard diet was supplemented with 20 mg/kg CdCl2; liver tissue was collected on the 40th day of the experiment. Immunofluorescence, qRT-PCR, and western blot were performed to detect the expression of miR-369, Th1/Th2 biomarkers, endoplasmic reticulum (ER) stress-related genes, and apoptotic genes. TUNEL assay was applied to stain apoptotic hepatocytes. In the Cd group, the apoptosis of hepatocytes was significantly increased, and associated with the declined expression of miR-369, Th1 polarization, the elevated expression of ER stress pathway genes and their downstream pro-apoptosis genes, and downregulated expression of anti-apoptotic genes. These results manifest that subacute Cd exposure mediates Th1 polarization to promote ER stress-induced porcine hepatocyte apoptosis via regulating miR-369-TNFα. These results not only provide a basis for the enrichment of Cd toxicology but also support a theoretical foundation for the prevention and therapy of Cd poisoning. Schematic diagram illustrating the proposed mechanism of subacute cadmium exposure modulates Th1 polarization to trigger ER stress-induced porcine hepatocyte apoptosis via regulation of miR-369-TNFα axis.

Abstract
Food allergy is a pathological immune reaction triggered by normal innocuous dietary proteins. Soybean is widely used in many food products and has long been recognized as a source of high-quality proteins. However, soybean is listed as one of the 8 most significant food allergens. The prevalence of soybean allergy is increasing worldwide and impacts the quality of life of patients. Currently, the only strategy to manage food allergy relies on strict avoidance of the offending food. Nutritional supplementation is a new prevention strategy which is currently under evaluation. Selenium (Se), as one of the essential micronutrients for humans and animals, carries out biological effects through its incorporation into selenoproteins. The use of interventions with micronutrients, like Se, might be an interesting new approach. In this review we describe the involvement of Se in a variety of processes, including maintaining immune homeostasis, preventing free radical damage, and modulating the gut microbiome, all of which may contribute to in both the prevention and treatment of food allergy. Se interventions could be an interesting new approach for future treatment strategies to manage soybean allergy, and food allergy in general, and could help to improve the quality of life for food allergic patients.

Abstract
A Selenium (Se) is an element belonging to the nonmetallic group. It was first discovered in 1817 by J.J. Berzelius. Until the 1950s, it was considered to be toxic to animals. However, with increasing research conducted on laboratory animals, it is now clear that Se is necessary for the proper functioning of both plants and animals. Recent studies indicate that Se is necessary for the proper functioning of metabolic pathways in animals. It was evidenced that Se is a component of about 100 proteins involved in the immune system, antioxidant homeostasis, or release of an inflammatory mediator. Therefore, it is of key interest to find the appropriate dosage for the supplementation of Se in the diet of farm animals and thereby eliminate physiological disorders in the body associated with Se imbalance. In this study, we present a literature review on the importance and appropriate dosage of Se in the diet of poultry concerning their health status, production results, and the quality of animal-origin products.

Abstract
Selenium is an essential trace element that can regulate the function of immnue cells via selenoproteins. However, the effects of selenium on human dendritic cell (DCs) remain unclear. Thus, selenoprotein levels in monocytes, immature DCs (imDCs) and mature DCs (mDCs) treated with or without Na2SeO3 were evaluated using RT-PCR, and then the immune function of imDCs and mDCs was detected by flow cytometry, cell counting and the CCK8 assay. In addition, the effects of Se on cytokine and surface marker expression were investigated by RT-PCR. The results revealed different expression levels of selenoprotein in monocytes, imDCs and mDCs, and selenoproeins could be regulated by Se. Moreover, it was indicated that anti-phagocytic activity was improved by 0.1 µM Se, whereas it was suppressed by 0.2 µM Se in imDCs; The migration of imDCs and mDCs was improved by 0.1 µM Se, whereas their migration was inhibited by treatment with 0.05 or 0.2 µM Se; The mixed lymphocyte reaction of mDCs was improved by 0.1 µM Se, and it was inhibited by 0.05 and 0.2 µM Se. In addition, 0.1 µM Se improved the immune function of DCs through the regulation of CD80, CD86, IL12-p35 and IL12-p40. Wheres 0.05 and 0.2 µM Se impaired immune function of DCs by up-regulation of interleukin (IL-10) in imDCs and down-regulation of CD80, CD86, IL12-p35 and IL12-p40 in mDCs. In conclusion, 0.1 µM Se might improve the immune function of human DCs through selenoproteins.

Abstract
Selenium levels can regulate the function of T cells, macrophages, B cells, natural killer cells and other immune cells. However, the effect of selenium on the immune function of dendritic cells (DCs) isolated from selenium-supplemented mice is unknown. In this study, C57BL/6J mice were randomly divided into three groups and fed diets containing low (0.08 ppm), medium (0.25 ppm) or high (1 ppm) selenium levels for 8 weeks. Immature (imDCs) and mature (mDCs) dendritic cells were then isolated from the bone marrow. Next, the migration, phagocytic capacity and mixed lymphocyte reaction (MLR) for imDCs and mDCs were detected by transwell and flow cytometry. The levels of C-C chemokine receptor type 7 (CCR7), major histocompatibility complex II (MHCII) and reactive oxygen species (ROS) were assayed by flow cytometry. F-actin and superoxide dismutase (SOD) activity was detected by fluorescence microscopy and SOD assay kit, respectively. In addition, the extracellular signal-regulated kinase (ERK), Akt, Ras homolog gene family member A/Rho-associated protein kinase (RhoA/ROCK) signalling, selenoprotein K (SELENOK) and glutathione peroxidase 1 (GPX1) levels were measured by western blot analysis. The results indicated that selenium deficiency enhanced the migration of imDCs by ROS and SELENOK-mediated ERK, Akt and RhoA/ROCK pathways but impaired the antigen uptake of imDCs. Although a high selenium level inhibited the migration of imDCs, it had no effect on phagocytic capacity. For mDCs, low selenium levels impaired free migration, and high levels inhibited the chemotactic migration involved in F-actin and CCR7, respectively. Low and high selenium levels impaired the MLR by inhibiting MHCII surface localisation, which might be related to ROS- and SELENOK-mediated ERK, Akt and RhoA/ROCK signalling pathways. In summary, selenium may regulate the immune function of mouse DCs through the ROS- and SELENOK-mediated ERK, Akt and RhoA/ROCK signalling.

ENVIRONMENT INTERNATIONAL 2021; 153:106508. [PMID: 33901931 DOI: 10.1016/j.envint.2021.106508] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Revised: 02/12/2021] [Accepted: 03/05/2021] [Indexed: 06/12/2023]
Abstract
BACKGROUND While several heavy metals and trace minerals have been linked with hypertensive disorders during pregnancy (HDP) in women, no studies have estimated the relationship of exposure to these chemicals, both independently and as a mixture, with systolic blood pressure (SBP) or diastolic blood pressure (DBP) over gestation. OBJECTIVES We examined individual and joint effects of 1st trimester chemicals with SBP and DBP over gestation, and whether those chemicals were associated with HDP. METHODS We used data from 1832 non-obese pregnant women with low-risk antenatal profiles from the Eunice Kennedy Shriver National Institute of Child Health and Human Development Fetal Growth Studies - Singleton cohort (2009-2013). In plasma collected from women at 8-13 weeks' gestation (baseline enrollment), we measured heavy metals, barium (Ba), cesium (Cs), antimony (Sb), as well as trace minerals, cobalt (Co), copper (Cu), molybdenum (Mo), selenium (Se), and zinc (Zn). We obtained BP at baseline and throughout gestation until delivery and diagnosis of HDP from medical records. We used Bayesian Kernel Machine Regression (BKMR) as well as traditional linear and logistic regressions to examine the cross-sectional associations of chemicals with baseline BP and HDP. We used linear mixed effect regression to examine longitudinal associations between chemicals and rate of weekly change in BP in each trimester. We adjusted for sociodemographic and lifestyle factors and pre-pregnancy body mass index in all models. RESULTS BKMR revealed that comparing the entire chemical mixture at the 90th percentile vs. the 50th percentile was associated with a 1.61 mmHg (95% CI: 0.41, 2.81) higher SBP and a 1.09 mmHg (0.10, 2.09) higher DBP. No interactions were observed between chemicals. Accounting for chemical co-exposure in BKMR, each interquartile range (IQR) increment in Cu was associated with a 0.67 mmHg (0.02, 1.32) higher SBP and a 0.60 mmHg (0.08, 1.12) higher DBP at baseline; each IQR increment in Se was associated with a 0.67 mmHg (0.05, 1.29) higher SBP but not DBP. In longitudinal analyses, women with higher (i.e., above median concentration) baseline Cu had a 0.09 mmHg (0.01, 0.17) and 0.06 mmHg (0.001, 0.12) larger weekly decrease in SBP and DBP in 2nd trimester, respectively. Women with higher baseline Ba had a 0.12 mmHg (0.04, 0.20) larger weekly increase in SBP in 2nd trimester, while women with higher Cs had a 0.05 mmHg (0.01, 0.10) larger weekly increase in DBP in 3rd trimester. None of the chemicals examined were significantly associated with HDP. CONCLUSIONS In this multi-ethnic cohort of women with low antenatal risk, plasma metals and trace minerals in early pregnancy, both individually and as a mixture, were statistically significantly associated with BP during gestation in small magnitude and in different directions, but not with HDP. The implications of these findings for women's postpartum BP and future cardiovascular health remains to be investigated.

Abstract
Manganese (Mn) is a ubiquitous heavy metal pollutant in environment, and excess Mn can damage nervous system of humans and animals. However, molecular mechanism of Mn-induced poultry neurotoxicity on inflammatory injury is still not fully clear. Thus, the purpose of the conducted research was to explore molecular mechanism of inflammatory injury caused by Mn in chicken nervous system. Two Mn poisoning models were established in vivo and in vitro. One hundred and eighty chickens were randomly separated into four groups. One control group was raised drinking water and standard diet. Three Mn groups were raised drinking water, and the standard diet supplemented with three different concentrations of MnCl2 ∙ 4H2O. There were 45 birds and 3 replicates in each group. Neurocytes from chicken embryos were cultured in mediums without and with six different concentrations of MnCl2 ∙ 4H2O in vitro. Our experiments showed that excess Mn caused cerebral histomorphological structure alternations and damage, and increased the expressions (P < 0.05) of inflammation-related factor NF-κB, TNF-α, iNOS, COX-2, and PTGEs in vivo and in vitro, meaning that excess Mn caused inflammatory damage and inflammatory response in chicken nervous system. Moreover, there were an upregulated IFN-γ mRNA expression and a downregulated IL-4 mRNA expression (P < 0.05) in bird cerebra and embryonic neurocytes after exposure to Mn, indicating that Mn exposure caused Th1/Th2 imbalance and immunosuppression. Additionally, in our research, the elevation (P < 0.05) of five HSPs (HSP27, HSP40, HSP60, HSP70, and HSP90) was found, suggesting that HSPs participated molecular mechanism of Mn stress. In addition, the inflammatory toxicity of Mn to chicken nervous system was time- and dose-dependent. Taken all together, our findings indicated that Th1/Th2 imbalance and HSPs mediated Mn-caused inflammatory injury via NF-κB pathway in chicken nervous system in vivo and in vitro.

Abstract
Selenium, an essential trace element in the body, participates in various biological processes in the form of selenoproteins. In humans, a suitable concentration of selenium is essential for maintaining normal cellular function. Decreased levels of selenoproteins can lead to obstruction of the normal physiological functions of tissues and cells and even death. In addition, the level of selenium in the body affects cellular immunity, humoral immunity, and the balance between type 2 and type 1 helper T cells. Selenium can affect the immune function of the body through the reactive oxygen species (ROS), NF-κB, ferroptosis and NRF2 pathways. This paper reviews the immune effect of selenium on the body and the process of signal transduction and aims to serve as a reference for follow-up studies of immune function and research on the development of new selenium compounds and active targets.

Abstract
Introduction The contribution of Th17 cytokines to autoimmune thyroid disease (AITD) is generally accepted. However, the roles of Th17 cells in the initiation and progression of Hashimoto's thyroiditis (HT) and Graves' disease (GD) remain unclear. Selenium deficiency, along with genetic predisposition and environmental factors, may have a role in thyroid autoimmunity. Aim We aimed to assess (1) the Th17 immune response by measuring plasma levels of Th17‐ and Treg‐associated cytokines and (2) the selenium status in treatment‐naïve Latvian patients with newly diagnosed GD or HT. Methods Eleven GD patients, 41 HT patients, and 26 healthy subjects were recruited for this study. Plasma levels of IL‐17a, IL‐22, IL‐23, IL‐6, and IL‐10 were detected by xMAP technology, while selenium was detected fluorometrically. Results and Conclusions No significant differences in IL‐17a, IL‐22, IL‐23, IL‐6, or IL‐10 levels were found among the HT patients, GD patients, and controls. In the HT patients, IL‐17a levels were positively correlated with IL‐22, IL‐23, IL‐6, and IL‐10, while IL‐22 was correlated with IL‐6, IL‐23, and IL‐10. In the GD patients, IL‐17a levels were positively correlated with IL‐22, IL‐23, and IL‐10; IL‐22 was positively correlated with IL‐23, IL‐6, and IL‐10; FT3 was positively correlated with IL‐17a, IL‐23, and IL‐10; and FT4 was positively correlated with IL‐17a and IL‐10 levels. Plasma selenium levels were negatively correlated with antithyroid peroxidase antibody titers in the HT patients. Although no difference in selenium levels was observed between the AITD patients and controls, the selenium status of the Latvian patients with GD or HT was at a suboptimal level.

Abstract
The selenium (Se) enrichment of yeasts and lactic acid bacteria (LAB) has recently emerged as a novel concept; the individual health effects of these beneficial microorganisms are combined by supplying the essential micronutrient Se in a more bioavailable and less toxic form. This study investigated the bioavailability of Se in the strains Enterococcus faecium CCDM 922A (EF) and Streptococcus thermophilus CCDM 144 (ST) and their respective Se-enriched forms, SeEF and SeST, in a CD (SD-Sprague Dawley) IGS rat model. Se-enriched LAB administration resulted in higher Se concentrations in the liver and kidneys of rats, where selenocystine was the prevalent Se species. The administration of both Se-enriched strains improved the antioxidant status of the animals. The effect of the diet was more pronounced in the heart tissue, where a lower glutathione reductase content was observed, irrespective of the Se fortification in LAB. Interestingly, rats fed diets with EF and SeEF had higher glutathione reductase activity. Reduced concentrations of serum malondialdehyde were noted following Se supplementation. Diets containing Se-enriched strains showed no macroscopic effects on the liver, kidneys, heart, and brain and had no apparent influence on the basic parameters of the lipid metabolism. Both the strains tested herein showed potential for further applications as promising sources of organically bound Se and Se nanoparticles.

Abstract
Background Selenium and peroxynitrite are known to support the growth and activity of immune cells, including T cells, B cells and macrophages. However, the role of these factors in the immune function of human immature dendritic cells (imDCs) is not clear. Material/Methods Monocytes from a mixture of blood samples were isolated using Ficoll density gradient centrifugation and purified with immunomagnetic beads before being induced into imDCs. Cells then either received no treatment (control group), or treatment with sodium selenite (Na2SeO3, Se), 3-morpholinosydnonimine (SIN1, which decomposes into peroxynitrite), or Se+SIN1. Cell viability, migration, and antiphagocytic abilities, oxidative stress, and protein expression of extracellular signal-regulated kinases (ERK) and MMP2 were assessed using a CCK8 assay, cell counter and flow cytometry, microplate spectrophotometer, and Western blot analysis, respectively. Results Viability of imDCs was unaffected by 0.1 μmol/L of Na2SeO3, although 1 mmol/L of SIN1 decreased it significantly (P<0.05). Chemotactic migration and antiphagocytic abilities were inhibited and enhanced, respectively, by treatment with Na2SeO3 and SIN1 (P<0.05). Activities of superoxide dismutase and glutathione peroxidase were increased by Na2SeO3 and Se+SIN1 (P<0.001). Glutathione content decreased with exposure to Na2SeO3 and SIN1 (P<0.05), but increased after treatment with Se+SIN1 (P<0.05). Levels of reactive oxygen species only increased with SIN1 treatment (P<0.05). Treatment with Na2SeO3, SIN1 and Se+SIN1 increased ERK phosphorylation and decreased MMP2 protein expression (P<0.05). Conclusions Selenium and peroxynitrite can influence immune function in imDCs by regulating levels of reactive oxygen species or glutathione to activate ERK and promote antigen phagocytosis, as well as by decreasing MMP2 expression to inhibit chemotactic migration.

Abstract
Management of inflammatory bowel disease (IBD) has always been a challenge for physicians. Current treatment protocols may cause numerous adverse effects. Selenium is known for its putative antiinflammatory properties. Selenium is needed for the biosynthesis of enzymatically active selenoproteins, which contribute to antioxidative defense, and effective function of immune systems. Several studies have shown that patients with IBD have a lower selenium level compared to healthy subjects. Hence, experimental studies mimicking ulcerative colitis and Crohn's disease investigated the effect of selenium supplementation on IBD. Previous studies indicated the following: 1) Selenoproteins can curb the inflammatory response and attenuate oxidative stress. This antiinflammatory property caused remission in animal models of colitis. 2) Selenium supports protective gut microbiota, which indirectly improves management of IBD. 3) Selenium may block some of the predominant tumorigenesis pathways proposed in colitis-associated colorectal cancer. 4) Selenium supplementation showed promising results in preliminary clinical studies, particularly in patients with selenium deficiency. While selenium supplementation seems to be beneficial for IBD, clinical studies have remained too preliminary in this regard. Randomized clinical trials are needed to measure the short-term and long-term effects of selenium on both active and quiescent IBD, particularly in patients with IBD who have documented selenium deficiency.

Abstract
Cadmium (Cd) is a toxic heavy metal and widespread in environment and food, which is adverse to human and animal health. Food intervention is a hot topic because it has no side effects. Selenium (Se) is an essential trace element, found in various fruits and vegetables. Many previous papers have described that Se showed ameliorative effects against Cd. However, the underlying mechanism of antagonistic effect of Se against Cd-induced cytotoxicity in avian leghorn male hepatoma (LMH) cells is unknown, the molecular mechanism of Se antagonistic effect on Cd-induced and calcium (Ca2+) homeostasis disorder and crosstalk of ER stress and autophagy remain to be explored. In order to confirm the antagonistic effect of Se on Cd-induced LMH cell toxicity, LMH cells were treated with CdCl2 (2.5 μM) and Na2SeO3 (1.25 and 2.5 μM) for 24 h. In this study, Cd exposure induced cell death, disrupted intracellular Ca2+ homeostasis and Ca2+ homeostasis related regulatory factors, interfered with the cycle of cadherin (CNX)/calreticulin (CRT), and triggered ER stress and autophagy. Se intervention inhibited Cd-induced LDH release and crosstalk of ER stress and autophagy via regulating intracellular Ca2+ homeostasis. Moreover, Se mitigated Cd-induced Intracellular Ca2+ overload by Ca2+/calmodulin (CaM)/calmodulin kinase IV (CaMK-IV) signaling pathway. Herein, CNX/CRT cycle played a critical role for the protective effect of Se on Cd-induced hepatotoxicity. Based on these findings, we demonstrated that the application of Se is beneficial for prevention and alleviation of Cd toxicity.

Abstract
Glutathione peroxidase 3 (Gpx3) is a pivotal selenoprotein that acts as an antioxidant. However, the role of Gpx3 in maintaining the normal metabolism of cardiomyocytes remains to be elucidated in more detail. Herein, we employed a model of Gpx3 interference in chicken embryos in vivo and Gpx3 knockdown chicken cardiomyocytes in vitro. Real-time PCR, western blotting and fluorescent staining were performed to detect reactive oxygen species (ROS), the calcium (Ca2+) concentration, endoplasmic reticulum (ER) stress, myocardial contraction, inflammation and heat shock proteins (HSPs). Our results revealed that Gpx3 suppression increased the level of ROS, which induced Ca2+ leakage in the cytoplasm by blocking the expression of Ca2+ channels. The imbalance of Ca2+ homeostasis triggered ER stress and blocked myocardial contraction. Furthermore, we found that Ca2+ imbalance in the cytoplasm induced severe inflammation, and HSPs might play a protective role throughout these processes. In conclusion, Gpx3 suppression induces myocardial damage through the activation of Ca2+-dependent ER stress.

Abstract
Kidney is a primary target organ for mercuric chloride (HgCl2) toxicity. Selenium (Se) can exert antagonistic effect on heavy metals-induced organ toxicity by regulating the expression of selenoproteins. The objective of this study was to investigate the effect of HgCl2 on the gene expression of selenoproteins in chicken kidney. Sixty male Hyline brown chickens were randomly and evenly divided into two groups. After acclimatization for one week, chickens were provided with the standard diet as well as non-treated water (CON group), and standard diet as well as HgCl2-treated water (250 ppm, HgCl2 group). After seven weeks, kidney tissues were collected to examine the mRNA expression levels of 25 selenoproteins genes and protein expression levels of 4 selenoproteins. Moreover, correlation analysis and principal component analysis (PCA) were used to analyze the expression patterns of 25 selenoproteins. The results showed that HgCl2 exposure significantly decreased the mRNA expression of Glutathione peroxidase 1 (GPX1), GPX4, Thioredoxin reductase 2 (TXNRD2), Iodothyronine deiodinase 1 (DIO1), Methionine-Rsulfoxide reductase 1 (SELR), 15-kDa selenoprotein (SEP15), selenoprotein I (SELI), SELK, SELM, SELN, SELP, SELS, SELT, SELW, and SEPHS2. Meanwhile, HgCl2 exposure significantly increased the mRNA expression of GPX3, TXNRD1, and SELU. Western blot analysis showed that the expression levels of GPX3, TXNRD1, SELK, and SELN were concordant with these mRNA expression levels. Analysis results of selenoproteins expression patterns showed that HgCl2-induced the main disorder expression of selenoproteins with antioxidant activity and endoplasmic reticulum resident selenoproteins. In conclusion, selenoproteins respond to HgCl2 exposure in a characteristic manner in chicken kidney.

Abstract
The study investigated biosynthesis of selenoproteins by Saccharomyces. cerevisiae using inorganic selenium. Selenium supplement via two stages was carried out during fermentation and the physicochemical characteristics of selenoproteins and its antioxidant activities were examined through in vitro assessment procedures. After fermentation, dry cells weight (7.47 g/L) and selenium content (3079.60 μg/kg) in the yeast were achieved when fermentation time points at the 6th hour and the 9th hour were chosen to supplement 30% and 70% of 30 μg/mL Na2SeO3 respectively. A maximal yield of selenium content in selenoproteins reached 1013.07 μg/g under optimized culture conditions and was 133-fold higher than the control. One new band with molecular weight of 26.76 KDa appeared in conjugated selenoproteins of sodium dodecyl sulphate-polyacrylamide gel electrophoresis. Surface structure of selenoproteins and the control was different by Scanning electron microscopy images. Infrared spectrometry analysis demonstrated that groups of HSe, SeO and C-Se-O involved in selenoproteins were important pieces of evidence showing presence of Se embedded in the protein molecule. Selenoproteins showed strong antioxidant activities on DPPH·, OH and ·O2-, which was much higher than the control proteins. Therefore, the study provided an efficient selenium-enriched culture method of inorganic selenite to organic selenium and basis for selenoproteins applications.

Abstract
Selenium (Se) is an essential trace element to maintain homeostasis in humans and animals. The aim of the present study was to clarify the mechanism of Se deficiency-induced inflammation in the pig's brain. Twenty-four healthy pigs were randomly divided into two groups (n = 12/group): control group (group C) was fed diet with 0.3 mg/kg inorganic Se, and Se-deficient group (group L) was fed diet with 0.007 mg/kg inorganic Se. At the 90th day of the experiment, the histology in the pig's brain was observed by the microscope, the NO levels and iNOS activity were assayed, and the mRNA and protein expression levels of inflammatory cytokines (iNOS, COX-2, NF-κB, and PTGEs) and HSPs (HSP27, HSP40, HSP60, HSP70, and HSP90) were detected by real-time quantitative PCR and Western blot. Compared with group C, both of NO levels and iNOS activity were increased in group L, and the mRNA and protein expression levels of inflammatory cytokines (iNOS, COX-2, NF-κB, and PTGEs) and HSPs (HSP27, HSP40, HSP60, HSP70, and HSP90) were also upregulated; histological observation displayed inflammatory response in the brain of pig. In summary, diet with Se deficiency can activate the iNOS/NF-κB pathway to upregulate the expression of inflammatory cytokines, thereby leading to inflammatory lesions in the pig's brain, and HSPs are involved in the compensatory regulation of inflammation. This study provides a reference for the prevention of pig brain inflammation from the perspective of nutrition.

Abstract
Long noncoding RNAs (LncRNAs) have been demonstrated to be associated with a variety of myocardial diseases, but how LncRNAs regulate autophagy in selenium (Se)-deficient myocardial injury is infrequently reported. Here, we screened out a novel long noncoding RNA, microRNA, and ATG7 through transcriptomic results. We employed a Se-deficient chicken model in vivo, and primary cultured cardiomyocytes treated by correlation in vitro. The results showed that Se deficiency upregulated the expression of ATG7, and miR-17-5p inhibited cardiomyocyte autophagy by targeting ATG7. Furthermore, we found that LncRNA 0003250 regulated miR-17-5p, and thus affected the expression of ATG7 and autophagic cell death. Our present study proposed a novel model for the regulation of cardiomyocytes autophagy, which includes LncRNA 0003250, miR-17-5p and ATG7 in the chicken heart. Our conclusions may provide a feasible diagnostic tool for Se-deficient cardiomyocyte injury.

Abstract
Ammonia is a hazardous environmental pollutant that can be harmful to animal health. In this study, we aimed to evaluate the effect of ammonia exposure on broiler chicken spleens. We randomly divided one hundred twenty 1-day-old broiler chickens into 3 groups and raised them with exposure to different ammonia concentrations (low, middle, and high); at 42 D of age, the chicken spleens were extracted. We observed histopathologic changes in spleen tissues by microscopy and measured the expression of Th1/Th2 secreted cytokines (interleukin [IL]-1β, IL-2, IL-4, IL-6, IL-10, interferon-γ [IFN-γ], tumor necrosis factor-α) by RT-PCR. We also measured the expression of nuclear receptor-κB (NF-κB) pathway–related genes (cyclooxygenase-2 [COX-2], nitric oxide synthase [iNOS], and prostaglandin synthetase [PGE]) in spleens by RT-PCR and Western blot analysis. Histopathologic observations indicated that the spleen tissues were seriously injured in the high ammonia concentration group. There was abnormal cytokine expression, including increased IL-4, IL-6, and IFN-γ and decreased IL-2, which indicated an imbalance in the Th1/Th2 response. The proinflammatory factors such as NF-κB, COX-2, iNOS, and PGE were upregulated in the high ammonia group. In conclusion, this study illustrated that ammonia exposure led to a Th1/Th2 immune imbalance and triggered the NF-κB pathway, causing inflammatory damage to the spleen.

Abstract
Selenium (Se) deficiency has a significant impact on the swine breeding industry by inducing digestive system damage and diarrhea. However, the molecular mechanism remains unclear. Our objectives were to investigate if different amounts of necroptosis, inflammatory responses, and T helper cell 1/T helper cell 2 (Th1/Th2) imbalances were induced by Se deficiency in intestinal porcine jejunal epithelial cells (IPEC-J2) and swine ileum tissue. Therefore, Se-deficient models were successfully established both in vitro and in vivo. In the current study, the cell morphological observation results showed that Se deficiency seriously affected the growth and differentiation of IPEC-J2 cells. Moreover, the necroptosis staining and histomorphology observation results showed that the number of necroptotic cells increased significantly, and the ileal tissue exhibited abnormal structures, including necroptotic features and inflammatory cell infiltration, in the Se-deficient group. Furthermore, Se deficiency resulted in accelerated cell necroptosis by increasing (p < .05) the expression of genes related to the tumor necrosis factor-α pathway at both the protein and messenger RNA (mRNA) levels compared to the control group. Moreover, the relative mRNA and protein expression of the inflammatory genes and their responses to dietary Se deficiency were consistent with the resultant Th1/Th2 imbalances in vitro and in vivo. Taken together, the results suggested that Se deficiency caused necroptosis, inflammatory responses, and abnormal expression of cytokines in swine ileum tissue. These findings might help us to explain the damage induced by Se deficiency to the digestive system of swine.

Abstract
Arsenic and copper, two toxic pollutants, are powerful inducers of oxidative stress. Exposure to copper and arsenic can cause intestinal injury in cockerel. This study was carried out to investigate the effects of these two pollutants on the gastrointestinal tract of cockerels. Experimental results showed that the activity of antioxidant enzymes (catalase and glutathione peroxidase) was inhibited and the ionic balance was destroyed after exposure to copper sulfate (300 mg/kg) and/or arsenic trioxide (30 mg/kg). However, the expression of pro-inflammatory cytokines (nuclear factor kappa-B, cyclooxygenase-2, tumor necrosis factor-α, and prostaglandin E2 synthases) increased markedly. Damages to the biofilm structure and inflammatory cell infiltration were simultaneously observed during histological examination. Heat-shock proteins were also expressed in large quantities after exposure to the poisons. Collectively, exposure to arsenite and/or Cu2+ can cause rectal damage in cockerels, inducing inflammation and an imbalance in immune system responses. Sometimes, exposure to both pollutants can produce even more toxic effects. Heat-shock proteins can protect the tissue from the exotoxins but the specific mechanisms require exploration. After oral ingestion of toxins, the rectum can still be damaged, necessitating attention to the safety of poultry breeding, human food safety, and environmental protection.

Abstract
Selenium (Se) is a trace element for human and animal health. Cadmium (Cd) is a known human carcinogen. The effects of Cd on the environment and humans are well known. Because chickens are at the top of the food chain, it is a good experimental animal model for assessing heavy metal toxicity and its potential threat to humans. Selenomethionine (Se-met) is a suitable form for nutritional Se supplementation. Therefore, the toxicity of Cd to the chicken liver and the antagonistic effects of Se-met on Cd were examined at the molecular level in the present study. The results showed that oxidative stress indicators (apoptosis-related genes, P13K/AKT pathway-related genes, and heat shock proteins (HSPs)-related genes) in the Cd group have changed significantly, indicating Cd induced hepatocyte stress and apoptosis. Interestingly, the changes in oxidative stress indicators (apoptosis-related genes, P13K/AKT pathway-related genes, and HSPs-related genes) in the Cd-Se-met group were mitigated compared with the control group. Our results indicated that Cd can induce hepatocyte apoptosis and stress in the chickens. Se-met has an ameliorative effect on Cd-induced apoptosis of chicken hepatocyte by regulating PI3K/AKT pathway. Our findings will provide a new insight for better understanding of the detoxification function of Se-met to heavy metals.

Abstract
Selenium (Se) is important in many physiological processes, such as antioxidant processes and inflammation. The aim of our experiments was to investigate the molecular mechanism that selenomethionine could reduce the lipopolysaccharide (LPS)-induced inflammation by inhibiting the TLR4-NF-κB-NLRP3 signaling pathway. Eighty broilers were randomly and evenly divided into two groups, giving normal Se content diets (Con group, 0.2 mg Se/kg diet) and Se-rich basal diets (Se group, 0.5 mg selenomethionine/kg diet) for 90 days. Se-rich basal diets were based on 0.2 mg/kg sodium selenite contained. Five hours before euthanized, 20 broilers were randomly selected from each group and given lipopolysaccharide (200 μg/kg BW) by intraperitoneal injection, Con+LPS group and Se+LPS group, respectively. The Con group and Se group were given equal saline by intraperitoneal injection. We observed the microscopic pathological changes of liver tissue detected oxidative stress by kit and detected the expression of inflammatory factors, heat shock protein (HSP), and nod-like receptor protein 3 (NLRP3)-related genes by qRT-PCR and Western blot. With the microscope, we found the Con+LPS group had obvious inflammatory lesions such as sinusoidal congestion, but the damage was significantly alleviated in the Se+LPS group. In the Con+LPS group, the activity of GSH-Px and the content of GSH were significantly decreased compared with those in the Con group; however, they are increased in the Se group and in the Se + LPS group. Inflammatory factors (MyD88, NF-κB, TNF-α, IL-1β, IL-6, IL-12, IL-18, iNOS, and COX-2), heat shock proteins (HSP27, HSP60, HSP70, and HSP90), and the expression of NLRP3 and caspase-1 increased in the Con+LPS group compared with those in the Con group, while they were lower in the Se+LPS group than in the Con+LPS group. We concluded that selenomethionine inhibits the LPS-induced inflammation of liver tissue via suppressing the TLR4-NF-κB-NLRP3 signaling pathway.

Abstract
Aluminum (Al) poisoning has been linked to the development of several reproductive system dysfunctions. Dietary supplementation with selenium-rich yeast (SeY) has been shown to prevent a variety of pathologic conditions. In the present study, the potential protect role of SeY on Al-induced testicular toxicity was evaluated, and the possible underlying mechanisms were discussed. Mice were treated with SeY (0.1 mg/kg) and/or Al (10 mg/kg) by oral gavage for 4 weeks. Histopathologic changes were observed in the testes of Al-treated mice. Oxidative stress, ionic disturbances, and the generation of NO systems are believed to have resulted in the observed pathology. Interestingly, SeY supplementation significantly inhibited the Al-induced histopathological and molecular changes and restored these indicators to levels observed in the control animals. These results suggest that SeY exerts a testis-protective effect against Al-induced toxicity through the reduction of oxidative stress, NO production, and the maintenance of ionic homeostasis.

Abstract
Multiple tissue necrosis is one of the morphological features of selenium deficiency-mediated injury. MicroRNA (miRNA) participates in the occurrence and development of necroptosis by regulating target genes. Necroptosis is a programmed form of necrosis, and it is closely related to lipopolysaccharide (LPS)-induced injury. Our aim was to investigate whether Se deficiency can promote tracheal injury caused by LPS through miRNA-induced necroptosis. By establishing models of tracheal injury in Se-deficient chickens, we verified the targeting relationship between chicken-derived miR-16-5p and PI3K through bioinformatics, qRT-PCR and WB analyses, and we measured the changes in the expression of genes related to the PI3K/AKT pathway, RIP3/MLKL pathway and MAPK pathway and of heat shock proteins. Under the condition of Se deficiency, the following results were observed: PI3K/AKT expression decreased with the upregulation of miR-16-5p, the expression of necroptosis-related factors (TNF-α, RIP1, FADD, RIP3 and MLKL) increased, and the expression of Caspase 8 significantly decreased (p < 0.05). Light microscopy observations indicated that cell necrosis was the main pathological change due to Se deficiency injury in the tracheal epithelium. The MAPK pathway was activated, and HSP expression was upregulated, indicating that the MAPK pathway and HSPs are both involved in Se deficiency-mediated necroptosis. In addition, Se deficiency promoted the expression of necroptosis-related genes in LPS-treated chickens (p < 0.05), and the pathological changes of cell necrosis were more obvious. In conclusion, we demonstrated that Se deficiency regulates the miR-16-5p-PI3K/AKT pathway and exacerbates LPS-induced necroptosis in chicken tracheal epithelial cells by activating necroptosis-related genes.

Abstract
Aluminum (Al) poisoning is linked to the development of cardiovascular diseases, and dietary supplementation with selenium-rich-yeast (SeY) has been shown to prevent inflammatory conditions. We evaluated the preventive effect of SeY on Al-induced cardiotoxicity, and the possible underlying mechanisms. Mice were treated with SeY (0.1 mg/kg) and/or Al (10 mg/kg) by oral gavage for 4 weeks. Histopathological damage was observed in the heart of Al-treated mice, in addition to the transcriptional up/downregulation of nuclear xenobiotic receptors (NXRs), inflammatory cytokines and 15 CYP450s genes. SeY significantly inhibited these Al-induced histopathological and molecular changes, and restored these indicators to the control levels. These results suggest that SeY exerts a cardio-protective effect against Al-induced toxicity through the NXR system, inflammatory cytokines, and CYP450s genes.
