Antioxidants (Basel) 2023; 12:1685. [PMID: 37759988 PMCID: PMC10525281 DOI: 10.3390/antiox12091685] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2023] [Revised: 08/26/2023] [Accepted: 08/26/2023] [Indexed: 09/29/2023] Open
Abstract
Earlier studies have shown that selenomethionine (SM) supplements in broiler breeders had higher deposition in eggs, further reduced the mortality of chicken embryos, and exerted a stronger antioxidant ability in offspring than sodium selenite (SS). Since previous studies also confirmed that Se deposition in eggs was positively correlated with maternal supplementation, this study aimed to directly investigate the antioxidant activities and underlying mechanisms of SS and SM on the chicken hepatocellular carcinoma cell line (LMH). The cytotoxicity results showed that the safe concentration of SM was up to 1000 ng/mL, while SS was 100 ng/mL. In Se treatments, both SS and SM significantly elevated mRNA stability and the protein synthesis rate of glutathione peroxidase (GPx) and thioredoxin reductase (TrxR), two Se-containing antioxidant enzymes. Furthermore, SM exerted protective effects in the H2O2-induced oxidant stress model by reducing free radicals (including ROS, MDA, and NO) and elevating the activities of antioxidative enzymes, which performed better than SS. Furthermore, the results showed that cotreatment with SM significantly induced apoptosis induced by H2O2 on elevating the content of Bcl-2 and decreasing caspase-3. Moreover, investigations of the mechanism revealed that SM might exert antioxidant effects on H2O2-induced LMHs by activating the Nrf2 pathway and enhancing the activities of major antioxidant selenoenzymes downstream. These findings provide evidence for the effectiveness of SM on ameliorating H2O2-induced oxidative impairment and suggest SM has the potential to be used in the prevention or adjuvant treatment of oxidative-related impairment in poultry feeds.

Abstract
To investigate selenium (Se) concentrations in serum of patients with rheumatoid arthritis (RA), osteoarthritis (OA), and Kashin-Beck disease (KBD), together with the effect of Se supplement (chondroitin sulfate [CS] nano-Se [SeCS]) on CS structure-modifying sulfotransferases in KBD chondrocyte. Fifty serum samples from each group with aged-matched (40-60 years), normal control (N), RA, OA, and KBD (25 males and females, respectively) were collected to determine Se concentrations. Furthermore, the KBD chondrocytes were divided into two groups following the intervention for 24 h: (a) non-treated KBD group and (b) SeCS-treated KBD group (100 ng/mL SeCS). The ultrastructural changes in chondrocytes were observed by transmission electron microscopy (TEM). Live/dead staining was used to observe cell viability. The expression of CS-modifying sulfotransferases including carbohydrate sulfotransferase 12, 13, and 15 (CHST-12, CHST-13, and CHST-15, respectively), and uronyl 2-O-sulfotransferase (UST) were examined by quantitative real-time polymerase chain reaction and western blotting analysis after SeCS intervention. The Se concentrations in serum of KBD, OA, and RA patients were lower than those in control. In OA, RA, and control, Se concentrations were higher in male than in female, while it is opposite in KBD. In the cell experiment, cell survival rate and mitochondrial density were increased in SeCS-treated KBD groups. Expressions of CHST-15, or CHST-12, and CHST-15 on the mRNA or protein level were significantly increased. Expression of UST slightly increased on the mRNA level, but no change was visible on the protein level. Se deficiency in serum of RA, OA, and KBD was observed. SeCS supplemented in KBD chondrocytes improved their survival rate, ameliorated their ultrastructure, and increased the expression of CS structure-modifying sulfotransferases.

Abstract
Selenium is a trace element of both nutritional and toxicological interest, depending on its dose and chemical form. Diet is the primary source of exposure for most individuals. We sought to investigate the influence of food intake on serum levels of selenium species. Among fifty subjects randomly selected from a Northern Italian population, we assessed dietary habits using a validated semi-quantitative food frequency questionnaire. We also measured circulating levels of selenium species in serum using high pressure liquid chromatography associated with inductively-coupled plasma dynamic reaction cell mass spectrometer. Circulating levels of inorganic selenium, the most toxic selenium species, were positively associated with intake of fish, legumes and dry fruits, and inversely associated with intake of dairy products and mushrooms. Concerning the organic selenium species, selenoproteinP-bound selenium was inversely associated with intake of fish, fresh fruits, vegetables, and legumes, while selenocysteine-bound selenium positively associated with intake of fresh fruit, potato, legume and mushroom. In the present study, intakes of different foods were correlated with different types of selenium species. These results have important public health implications when assessing the nutritional and toxicological potential of diet composition with reference to selenium exposure.

Abstract
The aim of the present study was to examine the effect of selenium (Se) deficiency on the expression of selenoproteins in chicken muscular stomach and to detect the correlation of selenoproteins with muscular stomach injuries. One-day-old broiler chickens were maintained for 55 days on a normal diet (0.2 mg/kg) or a Se-deficient diet (0.033 mg Se/kg). The expression levels of 25 selenoproteins, heat shock proteins (HSPs), and inflammatory factors were then examined by real-time PCR. Following this, the correlation between selenoproteins, HSPs, and inflammatory factors was analyzed by principal component analysis (PCA). The results showed that Se deficiency decreased the expression of 25 selenoproteins (P < 0.05), but increased the expression of HSP27, HSP40, HSP60, HSP70, and HSP90, and NF-κB, iNOS, TNF-α, COX-2, and HO-1 (P < 0.05). Selenoproteins showed a high negative correlation with HSPs and inflammatory factors. Thus, the results suggested that Se deficiency induced muscular stomach injuries by decreasing the expression of selenoproteins. In addition, selenoproteins play an important role in regulating HSPs and inflammatory response. The muscular stomach is a key target of Se deficiency and may play a special role in response to Se deficiency.

Abstract
Selenophosphate synthetase (SPS) is essential for selenoprotein biosynthesis. In two SPS paralogues, SPS1 was only cloned from a cDNA library prepared from avian organ. However, the biological function of SPS1 in chicken central nervous system (CNS) remains largely unclear. To investigate the role of avian SPS1 in the development and selenium (Se) homeostasis of CNS, fertile eggs, chicken embryos, embryo neurons and chicks were employed in this study. The response of SPS1 transcription to the development and Se levels of CNS tissues was analyzed using qRT-PCR. SPS1 gene exists extensively in the development of chicken CNS. The wide expression of avian SPS1 can be controlled by the Se content levels, which suggests that SPS1 is important in the regulation of Se homeostasis. The fundamental mechanism of these effects is that Se alters the half-life and stability of SPS1 mRNA. Therefore, SPS1 exerts an irreplaceable biological function in chicken CNS and Se homeostasis is closely related to the expression of SPS1. These results suggested that SPS1 was required for the development and Se homeostasis of CNS in chicken.

Abstract
The aim of the present study was to investigate the effects of selenium (Se) deficiency on autophagy-related genes and on ultrastructural changes in the spleen, bursa of Fabricius, and thymus of chickens. The Se deficiency group was fed a basal diet containing Se at 0.033 mg/kg and the control group was fed the same basal diet containing Se at 0.15 mg/kg. The messenger RNA (mRNA) levels of the autophagy genes microtubule-associated protein 1 light chain 3 (LC3)-I, LC3-II, Beclin 1, dynein, autophagy associated gene 5 (ATG5), and target of rapamycin complex 1 (TORC1) were assessed using real-time qPCR. The protein levels of LC3-II, Beclin 1, and dynein were investigated using western blot analysis. Furthermore, the ultrastructure was observed using an electron microscope. The results indicated that spleen mRNA levels of LC3-I, LC3-II, Beclin 1, dynein, ATG5, and TORC1 and the protein levels of LC3-II, Beclin 1, and dynein were increased in the Se deficiency group compared with the control group. In the bursa of Fabricius, the mRNA levels of LC3-I, LC3-II, Beclin 1, dynein, ATG5, and TORC1 and the protein levels of Beclin 1 and dynein were increased; furthermore, the protein level of LC3-II was decreased in the Se deficiency group compared to the control group. In the thymus, the mRNA levels of LC3-I, Beclin 1, and ATG5 increased; the levels of LC3-II, dynein, and TORC1 were decreased; the protein level of Beclin 1 increased; and the levels of LC3-II and dynein decreased in the Se deficiency group compared to those in the control group. Further cellular morphological changes, such as autophagy vacuoles, autolysosomes, and lysosomal degradation, were observed in the spleen, bursa of Fabricius, and thymus of the Se-deficiency group. In summary, Se deficiency caused changes in autophagy-related genes, which increased the autophagic process and also caused structural damages to the immune organs of chickens.

Abstract
Selenium (Se) deficiency induces hemolysis in chickens, but the molecular mechanism for this effect remains unclear. Se primarily elicits its function through the activity of selenoproteins, which contain the unique amino acid selenocysteine (Sec). In this study, we aimed to investigate the effect of Se deficiency on the expression of 24 selenoproteins and 10 cytokines. One hundred eighty chickens were randomly divided into 2 groups (90 chickens per group). During the entire experimental period, chickens were allowed ad libitum consumption of feed and water. The chickens were fed either a Se-deficient diet (0.008 mg Se/kg; produced in the Se-deficient area of Heilongjiang, China) or a Se-supplemented diet (as sodium selenite) at 0.2 mg/kg for 35 days. At the 35th day, the messenger RNA (mRNA) levels of 24 selenoproteins and 10 cytokines were examined in erythrocytes of 5 chickens per group, and the correlation was analyzed. The results showed that the expression of 24 selenoproteins and 7 cytokines (IL-2, IL-4, IL-8, IL-10, IL-12β, TGF-β4, and IFN-γ) decreased (P < 0.05), and the expression of 3 cytokines (IL-1γ, IL-6 and IL-7) was higher in the Se-deficient group. In both groups, glutathione peroxidase (GPX), thioredoxin 1 (Txnrd1), selenoprotein P1 (SELP), and selenoprotein synthetase (SPS2) were highly expressed compared to the other selenoproteins in chicken erythrocytes (P < 0.05). These data suggest that GPXs, Txnrd1, SELP, and SPS2 possibly play a more important role than the other selenoproteins. The increase of pro-inflammatory cytokines (IL-1γ, IL-6, and IL-7) suggested that the immune system of chickens was damaged by the Se deficiency. Correlation analysis suggested that although the expression of 24 selenoproteins and 7 cytokines decreased and that of 3 cytokines increased, there was a close correlation between their expression levels and a Se diet. These results suggested that Se deficiency influenced the expressions of 24 selenoproteins and 10 cytokines in chicken erythrocytes, revealing a relationship between Se and the chicken immune system. This study offers information regarding the mechanism of Se deficiency-induced hemolysis.

Abstract
Selenium (Se) influences the metabolism of thyroid hormones in mammals. However, the role of Se deficiency in the regulation of thyroid hormones in chickens is not well known. In the present study, we examined the levels of thyroidal triiodothyronine (T3), thyroidal thyroxine (T4), free triiodothyronine, free thyroxine (FT4), and thyroid-stimulating hormone in the serum and the mRNA expression levels of 25 selenoproteins in chicken thyroids. Then, principal component analysis (PCA) was performed to analyze the relationships between the selenoproteins. The results indicated that Se deficiency influenced the conversion of T4 to T3 and induced the accumulation of T4 and FT4. In addition, the mRNA expression levels of the selenoproteins were generally decreased by Se deficiency. The PCA showed that eight selenoproteins (deiodinase 1 (Dio1), Dio2, Dio3, thioredoxin reductase 2 (Txnrd2), selenoprotein i (Seli), selenoprotein u (Selu), glutathione peroxidase 1 (Gpx1), and Gpx2) have similar trends, which indicated that they may play similar roles in the metabolism of thyroid hormones. The results showed that Se deficiency inhibited the conversion of T4 to T3 and decreased the levels of the crucial metabolic enzymes of the thyroid hormones, Dio1, Dio2, and Dio3, in chickens. In addition, the decreased selenoproteins (Dio1, Dio2, Dio3, Txnrd2, Seli, Selu, Gpx1, and Gpx2) induced by Se deficiency may indirectly limit the conversion of T4 to T3 in chicken thyroids. The information presented in this study is helpful to understand the role of Se in the thyroid function of chickens.

Abstract
Dietary selenium (Se) deficiency induces muscular dystrophy in chicken, but the molecular mechanism remains unclear. The aim of the present study was to investigate the effect of dietary Se deficiency on the expressions of 25 selenoproteins. One-day-old broiler chickens were fed either an Se deficiency diet (0.033 mg Se/kg; produced in the Se-deficient area of Heilongjiang, China) or a diet supplemented with Se (as sodium selenite) at 0.2 mg/kg for 55 days. Then, the mRNA levels of 25 selenoproteins in chicken muscles were examined, and the principal component was further analyzed. The results showed that antioxidative selenoproteins especially Gpxs and Sepw1 were highly and extensively expressed than other types of selenoproteins in chicken muscles. In 25 selenoproteins, Gpxs, Txnrd2, Txnrd 3, Dio1, Dio 3, Selk, Sels, Sepw1, Selh, Sep15, Selu, Selpb, Sepp1, Selo, Sepx1, and SPS2 were downregulated (P < 0.05), and other selenoproteins were not influenced (P > 0.05). Se deficiency decreased the expressions of 19 selenoproteins (P < 0.05), 11 of which were antioxidative selenoproteins. And, principal component analysis (PCA) further indicated that antioxidative selenoproteins, especially Gpx3, Gpx4, and Sepw1, may play crucial roles in chicken muscles. However, compared with these antioxidative selenoproteins, some other lower expressed selenoproteins (Dio1, Selu, Selpb, Sepp1) were excessively decreased (more than 60 %, P < 0.05) by Se deficiency. Thus, it may save the limited Se levels and be beneficial to remain the level of some crucial selenoproteins. These results suggested that Se deficiency mainly influenced the expressions of antioxidative selenoproteins in chicken muscles. And, antioxidative selenoproteins especially Gpxs and Sepw1 may play a crucial role in chicken muscles. Thus, it helps us focus on some specific selenoproteins when studying the role of Se in chicken muscles.

Abstract
Selenium (Se) deficiency induces pancreatic atrophy in chickens, but the molecular mechanism remains unclear. In this study, we investigated the effect of dietary Se deficiency on the expressions of 25 selenoproteins and the content of nitric oxide (NO) and examined the relationship between selenoproteins and NO. Chickens (180; 1 day old) were randomly divided into two groups, low (L) group (fed with Se deficient (Se 0.033 mg/kg) diet) and control (C) group (fed with normal (Se 0.2 mg/kg) diet). Then, pancreas was collected at 15, 25, 35, 45, and 55 days, and the content of NO, the activity of inducible NO synthase (iNOS), and the messenger RNA (mRNA) levels of 25 selenoproteins and iNOS were measured. The results showed that 25 selenoproteins were decreased (P < 0.05) by Se deficiency. Among them, thioredoxin reductase 1 (TXNRD1), selenoprotein S (SELS), selenoprotein U (SELU), selenoprotein X1 (SEPX1), and selenoprotein synthetase 2 (SPS2) were highly and extensively expressed than other types of selenoproteins in pancreas of chickens (P < 0.05). Thioredoxin reductase 2 (TXNRD2), glutathione peroxidase 1 (GPX1), glutathione peroxidase 3 (GPX3), selenoprotein I (SELI), iodothyronine deiodinase 1 (DIO1), selenoprotein P1 (SEPP1), selenoprotein W1 (SEPW1), selenoprotein O (SELO), selenoprotein T (SELT), selenoprotein M (SELM), selenoprotein X1 (SEPX1), and SPS2 were excessively decreased (P < 0.05). Meanwhile, NO content, iNOS activity, and mRNA level were increased strikingly compared with C group (P < 0.05). The correlation analysis suggested that NO had a strong negative correlation with GPX1, glutathione peroxidase 2 (GPX2), GPX3, DIO1, selenoprotein K (SELK), SELI, SEPX1, and SPS2. These results suggested that Se deficiency induced pancreatic injury by influencing NO and selenoproteins in pancreas of chickens. Thus, it offers some information on the mechanism of pancreatic injury induced by Se deficiency.

The role of selenoprotein W in inflammatory injury in chicken immune tissues and cultured splenic lymphocyte. Biometals 2014; 28:75-87.

Abstract
Selenoprotein W (SelW) is mainly understood in terms of its antioxidant effects in the cellular defense system. Inflammation is an important indicator of animal tissue injury, and the inflammatory cells may trigger a sophisticated and well-orchestrated inflammatory cascade, resulting in exaggerated oxidative stress. To investigate the role of SelW in inflammatory injury in chicken immune tissues and cultured splenic lymphocyte, in this report, the effects of selenium (Se) on mRNA expressions of SelW and inflammatory factors (iNOS, COX-2, NF-κB, PTGEs, and TNF-α) in the chicken immune organs (spleen, thymus and bursa of Fabricius) and cultured splenic lymphocyte treated with sodium selenite and H2O2, or knocked down SelW with small interfering RNAs (siRNAs) were examined. The results showed that Se-deficient diets effectively decreased the mRNA expression of SelW (P < 0.05), and induced a significantly up-regulation of COX-2, iNOS, NF-κB, PTGEs and TNF-α mRNA levels (P < 0.05). The histopathological analysis showed that immune tissues were obviously injured in the low-Se groups. In vitro, H2O2 induced a significantly up-regulation of the mRNA levels of inflammation-related genes (iNOS, COX-2, NF-κB, PTGEs, and TNF-α) in cultured splenic lymphocyte (P < 0.05). When lymphocytes were pretreated with Se before treated with H2O2, the inflammation-related genes were significantly decreased (P < 0.05). Silencing of SelW significantly up-regulated the inflammation-related genes (iNOS, COX-2, NF-κB, PTGEs, and TNF-α) in cultured splenic lymphocyte (P < 0.05). The results suggested that the expression levels of inflammatory factors (iNOS, COX-2, NF-κB, PTGEs, and TNF-α) and SelW can be influenced by Se in birds. SelW commonly played an important role in the protection of immune organs of birds from inflammatory injury by the regulations of inflammation-related genes.

Abstract
This study describes the effects of selenium (Se) deficiency on the messenger ribonucleic acid (mRNA) expression of 25 selenoproteins (Sels) (including glutathione peroxidases (GPx1-GPx4), thioredoxin reductases (TrxR1-TrxR3), iodothyronine deiodinases (ID1-ID3), selenophosphate synthetase 2 (SPS2), 15-kDa Sel (Sel15), SelH, SelI, SelK, SelM, Sepn1, SelO, Sepx, Selpb, SelS, SelT, SelW, Sepp1, and SelU in the adipose tissues (subcutaneous adipose, visceral adipose, and articular adipose) of chickens. One hundred and fifty 1-day-old chickens were randomly assigned to two groups of 75 each and were fed a low-Se diet (0.032 mg/kg Se) or a control diet (0.282 mg/kg Se). The expression levels of 25 Sel mRNAs were determined on days 35, 45, and 55 from three parts (subcutaneous adipose, visceral adipose, and articular adipose) of the chicken adipose tissues. The results showed that the expression levels of the 25 Sel mRNAs were significantly lower (P < 0.05) in the low-selenium group than in the control group. In addition, the Sel mRNA expression levels in the three adipose tissues were observed to decrease in a time-dependent manner with increasing feeding time.

Abstract
Dietary selenium (Se) deficiency can influence the function of the brain. Our objective was to investigate the effects of Se deficiency on oxidative damage and calcium (Ca) homeostasis in brain of chicken. In the present study, 1-day-old chickens were fed either a commercial diet (as control group) with 0.15 mg/kg Se or a Se-deficient diet (as L group) with 0.033 mg/kg Se for 75 days. Then, brain injury biomarkers were examined, including histological analysis, ultrastructure assay, and apoptosis assay. We also examined the effect of Se deficiency on the Se-containing antioxidative enzyme glutathione peroxidase (GSH-Px), the level of glutathione (GSH), and the Ca homeostasis in brain of chicken. The results showed that the levels of Se and GSH and activity of GSH-Px are seriously reduced by 33.8-96 % (P < 0.001), 24.51-27.84 % (P < 0.001), and 20.70-64.24 % (P < 0.01), respectively. In the present study, we also perform histological analysis and ultrastructure assay and find that Se deficiency caused disorganized histological structure, damage to the mitochondria, fusion of nuclear membrane and nucleus shrinkage, higher apoptosis rate (P < 0.001), and increase of Ca homeostasis (P < 0.05 or P < 0.01 or P < 0.001) in the brain of chicken. In conclusion, the results demonstrated that Se deficiency induced oxidative damage and disbalance of Ca homeostasis in the brain of chicken. Similar to mammals, chickens brain is also extremely susceptible to oxidative damage and selenium deficiency.

Priority in selenium homeostasis involves regulation of SepSecS transcription in the chicken brain. PLoS One 2012; 7:e35761.

Abstract
O-phosphoseryl-tRNA:selenocysteinyl-tRNA synthase (SepSecS) is critical for the biosynthesis and transformation of selenocysteine (Sec) and plays an important role in the biological function of Se through the regulation of selenoprotein synthesis. Selenium (Se) and Selenoprotein play a pivotal role in brain function. However, how intake of the micronutrient Se affects gene expression and how genetic factors influence Se metabolism in the brain is unknown. To investigate the regulation of SepSecS transcription induced by Se in the chicken brain, we determined the Se content of brain tissue, SepSecS gene expression levels and mRNA stability in the chicken brain and primary cultured chicken embryos neurons receiving Se supplements. These results showed that Se content in the brain remains remarkably stable during Se supplementation. A significant increase in SepSecS mRNA levels was observed in all of the brain tissues of chickens fed diets containing 1-5 mg/kg sodium selenite. Most strikingly, significant changes in SepSecS mRNA levels were not observed in neurons treated with Se. However, Se altered the SepSecS mRNA half-life in cells. These data suggest that Se could regulate SepSecS mRNA stability in the avian brain and that SepSecS plays an important role in Se homeostasis regulation.
