The Effects of Selenium-Enriched Probiotics on Growth Performance, Oocysts Shedding, Intestinal Cecal Lesion Scores, Antioxidant Capacity, and mRNA Gene Expression in Chickens Infected with Eimeria tenella. Biol Trace Elem Res 2021; 199:278-291.

Abstract
This study was carried out to investigate the effects of selenium-enriched probiotics (SP) supplementation on growth performance, oocysts shedding, intestinal lesions and antioxidant capacities, and mRNA gene expression of local Chinese yellow male chickens infected with Eimeria tenella. One-day-old 270 chickens were randomly assigned into five groups, each consisting of three replicates with 18 chickens per replicate. Chickens in the negative and positive controls (NC, PC, respectively) received basal diets only (0.11 mg Se/kg), whereas the other groups were supplied basal diets with probiotics and designated as (P, 0.11 mg Se/kg), sodium selenite (SS, 0.41 mg Se/kg), and (SP, 0.41 mg Se/kg) groups. At 21 days of age, except the NC group, all other groups were infected by oral gavage with 1.5 × 104 sporulated E. tenella oocysts per chicken. Three chickens were randomly selected from each group for serum, liver, and cecal specimen collection. The results showed that P, SS, and SP had significant increase weight gain and feed intake. Additionally, these groups showed higher activities of serum superoxide dismutase (SOD) and glutathione peroxidase-1 (GPx1) compared to the PC group, whereas feed conversion ratio (FCR), serum catalase (CAT) activity, and malondialdehyde (MDA) content remained lower. Moreover, P, SS, and SP groups had lower oocyst shedding and cecal lesion scores. Significant upregulation of the glutathione peroxidase-1 (GPx1), glutathione peroxidase-4 (GPx4), Selenium W (SelW), and interferon gamma (IFN-γ) mRNA expression were detected in the SP group, which was then followed by SS when compared to the P group, whereas mRNA expression down-regulated in the PC group compared to NC, P, SS, and SP. In the NC and P groups, there were no significant differences in mRNA expression, except that IFN-γ mRNA level upregulated in P. We concluded that selenium-enriched probiotic supplementation has profound effects in enhancing the growth performance, antioxidant capacities, mRNA gene expression, reduced of oocysts shedding, and the cecal lesion scores of chickens and do provide protection against E. tenella.

Abstract
The objective of this study was to determine the effects of cadmium (Cd) on histological changes, lipid metabolism, and oxidative and endoplasmic reticulum (ER) stress in the liver of layers. A total of 480 hens at 38 wk of age were randomly assigned in 5 groups that were fed a basal diet or basal diet supplemented with CdCl2 2.5H2O at 7.5, 15, 30, and 60 mg Cd/kg feed for 9 wk. The results showed that accumulation of Cd was the greatest in the kidney, followed by the liver, pancreas, and lung. Diet contaminated with 30 mg Cd/kg induced antioxidant defenses accompanied by the increase of the activities of antioxidant enzymes in the liver, while dietary supplementation with 60 mg Cd/kg decreased the antioxidant levels significantly (P < 0.05). Immunofluorescence assay showed Cd induced reactive oxygen species production and endoplasmic reticulum stress in hepatocytes. Exposure to 60 mg Cd/kg significantly upregulated the expression of cytochrome C, caspase 3, caspase 9, caspase 7, Grp78, and Chop (P < 0.05). Histopathology and quantitative real-time PCR results presented periportal fibrosis, bile duct hyperplasia, and periportal inflammatory cell infiltration in the liver accompanied by upregulating the expression of tumor necrosis factor-α, IL-6 and IL-10 in the 30- or 60-mg Cd/kg groups. Oil Red O staining and RT-qPCR results showed dietary supplementation with 7.5, 15, and 30 mg Cd/kg promoted the synthesis of lipid droplets and upregulated the expression of fatty acid synthase, while dietary supplementation with 60 mg Cd/kg attenuated the synthesis of lipid droplets and downregulated the expression of acyl-CoA oxidase 1, carnitine palmitoyltransferase-1, and perixisome proliferation-activated receptor α (P < 0.05). Besides, the expression of vitellogenin (VTG) II and microsomal triglyceride transfer protein were upregulated in the 7.5-mg Cd/kg group, and the expressions of apolipoprotein B, vitellogenin II, and apolipoprotein very-low-density lipoprotein-II were downregulated in the 30- and/or 60-mg Cd/kg groups (P < 0.05). Conclusively, although low-dose Cd exposure promoted the synthesis of lipids and lipoproteins in the liver, the increase of Cd exposure could trigger liver injury through inducing oxidative and endoplasmic reticulum stress and negatively affect lipid metabolism and yolk formation in laying hens.

Abstract
Dietary selenium (Se) deficiency is known to cause myodynia syndrome and Se influences immune responses by changing the expression of inflammatory cytokines and heat shock proteins (Hsps), but the details are not completely elucidated. In the present study, 72 1-day-old mice were divided into two groups; the first group was fed a Se-sufficient diet, while the second group was fed a Se-deficient diet. Skeletal muscles and blood samples were taken from all mice after 42 days of treatment. The activities of glutathione peroxidase (GPX) and glutathione (GSH), mRNA and protein expression levels of inflammatory cytokines (including TNF-α, inducible NO synthase, cyclooxygenase-2, and prostaglandin E synthases), protein expression levels of NF-κB, and the mRNA expression levels of Hsps in the skeletal muscles of mice were examined. The results showed that GPX and GSH activities were decreased, while the mRNA and protein expression levels of inflammatory cytokines and the mRNA levels of Hsps were increased by Se deficiency in mouse skeletal muscles. In the present study, the protective role of Se in oxidative stress, inflammatory cytokines, and Hsps in the skeletal muscles of mice was summarized.

Abstract
In the present study, specific small interfering RNA (siRNA) for selenoprotein K (Selk) gene was designed and transfected into chicken myoblasts. Then, the expressions of inflammatory factors (including induced nitric oxide synthase [iNOS], nuclear factor-kappa B [NF-κB], heme-oxygenase-1 [HO-1], cyclooxygenase-2 [COX-2], and prostaglandin E synthase [PTGEs]), inflammation-related cytokines (including interleukin [IL]-1β, IL-6, IL-7, IL-8, IL-17, and interferon [IFN]-γ), and heat shock proteins (HSPs) (including HSP27, HSP40, HSP60, HSP70, and HSP90) were examined at 24 and 72 h after transfection. The results showed that messenger RNA (mRNA) expressions of iNOS, NF-κB, HO-1, COX-2, IL-6, IL-7, IL-8, HSP 27, HSP 40, HSP 60, HSP 70, and HSP 90 were significantly increased (p < 0.05) at 24 and 72 h after siRNA transfection, and the mRNA expressions of PTGEs, IL-1β, IL-17, and IFN-γ were significantly increased and decreased (p < 0.05) at 24 and 72 h after siRNA transfection. The results also showed that the protein expressions of iNOS, NF-κB, HO-1, COX-2, HSP60, HSP70, and HSP90 were significantly increased (p < 0.05) at 24 and 72 h after siRNA transfection. The correlation analysis and principal component analysis (PCA) showed that PTGEs, IL-1β, IL-17, IFN-γ, HSP40, and HSP90 might play special roles in response to Selk silencing in chicken myoblasts. These results indicated that Selk silencing induced inflammation response by affecting the expression levels of inflammatory factors and inflammation-related cytokines, and the heat shock proteins might play protective roles in this response in chicken myoblasts.

Abstract
Selenium (Se) deficiency induces testicular functional disturbances, but the molecular mechanism remains unclear. In the present study, 1-day-old broiler chickens were maintained for 55 days with a normal diet (0.2 mg/kg) and a Se-deficient diet (0.033 mg Se/kg). Then, the messenger RNA (mRNA) levels of selenoproteins, heat shock proteins (HSPs), and inflammatory factors were examined. Se deficiency led to decreased selenoproteins (Gpx1, Selk, and Selh) and HSPs (HSP40, HSP60, and HSP90) (P < 0.05). However, the expression levels of Gpx2, Sepn1, Seli, Selpb, Sepx1, HSP27, and inflammatory factors (iNOS, TNF-α, COX-2, and HO-1) were increased by Se deficiency (P < 0.05). Gpx1, Selk, and Selh showed positive correlation with HSP40, HSP60, and HSP90, but negative correlation with HSP27, HSP70, iNOS, TNF-α, COX-2, and HO-1. However, Gpx2, Spen1, Seli, Selpb, and Sepx1 showed positive correlation with inflammatory factors and HSP27 and HSP70. Selenoproteins showed different correlation with HSPs and inflammatory factors and were classified into different groups in response to Se deficiency. The results suggested that selenoproteins play different roles in chicken testes, and we think that Gpx1 and Selk may play a special role in chicken testes.

Abstract
Ion homeostasis plays important roles in development of metabolic diseases. In the present study, we examined the contents and distributions of 25 ions in chicken muscles following treatment with selenium (Se) deficiency for 25 days. The results revealed that in chicken muscles, the top ranked microelements were silicon (Si), iron (Fe), zinc (Zn), aluminum (Al), copper (Cu) and boron (B), showing low contents that varied from 292.89 ppb to 100.27 ppm. After Se deficiency treatment, essential microelements [Cu, chromium (Cr), vanadium (V) and manganese (Mn)], and toxic microelements [cadmium (Cd) and mercury (Hg)] became more concentrated (P < 0.05). Elements distribution images showed generalized accumulation of barium (Ba), cobalt (Co), Cu, Fe and V, while Cr, Mn, and Zn showed pin point accumulations in muscle sections. Thus, the ion profiles were generally influenced by Se deficiency, which suggested a possible role of Se deficiency in muscle dysfunctions caused by these altered ion profiles.

Abstract
Long non-coding RNAs (lncRNAs) have been demonstrated to play a pivotal role in proliferation and differentiation of muscles. However, the study on the roles of lncRNAs in Selenium (Se) deficiency induced muscle injury is still unclear. In this study, deep sequencing was performed to profile lncRNAs and mRNAs of the muscles from the Se deficiency (-Se group) and control (C group) chickens. The results revealed that 38 lncRNAs (23 up-regulated and 15 down-regulated) and 687 mRNAs (285 up-regulated and 402 down-regulated) were significantly dysregulated expressed, and the significantly dysregulated pathway including Phagosome, Cardiac muscle contraction, and Peroxisome Proliferator-Activated Receptor (PPAR) in -Se group. The regulatory relationship between ALDBGALG0000005049 and stearoyl-CoA desaturase (SCD), which involved in PPAR pathway was verified. The results also showed that the decreased expressions of SCD, PPARα, PPARβ and PPARγ, and the increased expressions of interleukin (IL)-1β, IL-6, IL-8, and chemokine (C-C motif) ligand 4 (CCL4) along with silencing of ALDBGALG0000005049 in chicken myoblasts. Moreover, increased expressions of IL-1β, IL-6, IL-8, and CCL4 and inflammatory cell infiltration in microstructure of chicken muscles treated with Se deficiency were observed. This study displayed an overview of aberrantly expressed lncRNAs and mRNAs profiles and PPAR pathway, and revealed that downregulation of ALDBGALG0000005049 caused inflammation by regulating SCD in chicken muscle resulted from Se deficiency.

Abstract
Selenium deficiency is known to cause cardiovascular diseases. However, the role of Se deficiency in causing oxidative damage and inflammation injury to the aorta vessels of chickens is not well known. In the present study, 180 1-day-old chickens were randomly divided into two groups, a low-Se group (L group) and a control-Se group (C group). The messenger RNA (mRNA) levels of 25 selenoproteins, the mRNA and protein expression levels of inflammatory cytokines (including NF-κB, TNF-α, COX-2, and PTGES), and the antioxidant levels in chicken aorta vessels were examined. The results showed that the mRNA levels of 25 selenoproteins and the activity of Gpx were decreased, while the mRNA and protein expression levels of inflammatory cytokines and the MDA content were increased by Se deficiency in chicken aorta vessels. The data from the present study indicated that Se deficiency decreases the expression of selenoproteins, reduces antioxidant function, and increases the expression of inflammatory factors in chicken aorta vessels.

Abstract
Excessive selenium (Se) intake is harmful for animals and humans. The aim of the present study was to examine the effect of long-term excessive Se supplementation on oxidative stress and endoplasmic reticulum (ER) stress-related injuries in chicken spleen. A total of 180 1-day-old chickens were randomly divided into four groups with different Se dietary contents (0.2 mg/kg Se, 5 mg/kg Se, 10 mg/kg Se, or 15 mg/kg Se) for 45 days. Then, the levels of antioxidative enzymes, GPx, SOD, and MDA as well as the expression levels of GRP78, ARF6, caspase 3, caspase 12, and Bcl 2 in the spleen were determined at days 15, 30, and 45, respectively. The results showed that excessive Se treatment decreased the activities of GPx and SOD (P < 0.05) but increased the levels of MDA (P < 0.05) in a dose- and time-dependent manner. In addition, the ER stress genes GRP78 and ATF6 were highly expressed (P < 0.05), and the apoptosis genes caspase 3 and caspase 12 were increased, but Bcl 2 was decreased by Se treatment (P < 0.05). Correlation analysis showed that there was a high correlation between these biomarkers, which indicated that ER stress and ER stress-related apoptosis were correlated with oxidative stress. These results showed the important role of oxidative stress and ER stress in Se-related immune injuries in chicken.

Abstract
Exposure of people and animals to arsenic (As) is a global public health concern because As is widely distributed and associated with numerous adverse effects. As is a poisonous metalloid and arsenic trioxide (As2O3) is a form of As. Thus far, there have been very few reports on the inflammatory factor alterations of the gastrointestinal tract in birds exposed to As2O3. To investigate the possible correlation of As2O3 with inflammatory injury induced by an arsenic-supplemented diet in birds, 72 1-day-old male Hy-line cocks were selected and randomly divided into four groups. They were fed with either a commercial diet or an arsenic-supplemented diet containing 7.5, 15, and 30 mg/kg As2O3. The experiment lasted for 90 days, and samples of gizzard, glandular stomach, duodenum, jejunum, ileum, cecum, and rectum were collected at days 30, 60, and 90 of the experiment period. The inflammation-related genes were determined, including NF-κB, iNOS, COX-2, PTGEs, and TNF-α. The connection between arsenic dosage and inflammation-related genes was assessed. The content of inducible NO synthase (iNOS) was measured by Western blot of the samples. The results showed that arsenic supplementation increased the mRNA expression levels of inflammation-related genes in the gastrointestinal tract of cocks at different time points (p < 0.05). Moreover, the expression of the tissue and organ injury-related gene iNOS was upregulated (p < 0.05). These data suggest that As induces the inflammatory response and may trigger digestive function regression of the gastrointestinal tract by affecting inflammation-related genes and iNOS in cocks. This study offers some information on the mechanism of gastrointestinal tract inflammatory injury and iNOS expression level alterations induced by arseniasis.

Abstract
Selenium (Se) deficiency leads to many pathological changes in animals. However, there have been very few reports regarding chicken tissue injury in the kidney caused by Se deficiency. In this study, a chicken Se-deficient disease model has been constructed, and two renal function indexes [including creatinine (CREA) and uric acid (URIC)], seven renal antioxidative function indexes [including glutathione peroxidase (GPx), anti-hydroxyl radical (AHR), catalase (CAT), hydrogen peroxide (H2O2), nitrogen monoxide (NO), glutathione (GSH), and malonyldialdehyde (MDA)], and two organ/tissue injury-related indexes [including inducible nitric oxide synthase (iNOS) and inducible heme oxygenase (HO)-1] were detected and analyzed to investigate the effects of Se deficiency on chicken kidney tissue. The results showed that Se deficiency caused a significant increase in CREA and URIC levels and a decrease in renal antioxidative capacity. Meanwhile, Se deficiency upregulated the expression of organ/tissue injury-related genes, such as the messenger RNA (mRNA) of HO-1 and iNOS as well as their protein expression levels, in the chicken kidney tissue. These data suggest that Se deficiency in birds triggers renal function regression and oxidative stress in the kidney tissue.

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.
