Selenomethionine Attenuated H 2O 2-Induced Oxidative Stress and Apoptosis by Nrf2 in Chicken Liver Cells. 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.

Dietary glutathione supplementation attenuates oxidative stress and improves intestinal barrier in diquat-treated weaned piglets. Arch Anim Nutr 2023:1-14. [PMID: 37133420 DOI: 10.1080/1745039x.2023.2199806] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/04/2023]
Abstract
The aim of this study was to investigate the protective effects of glutathione (GSH) against oxidative stress and intestinal barrier disruption caused by diquat (an oxidative stress inducer) in weaned piglets. Twenty-four piglets were randomly assigned to four treatments with six pigs per treatment for an 18-d trial. Treatments were basal diet, basal diet + diquat challenge, 50 mg/kg GSH diets + diquat challenge and 100 mg/kg GSH diets + diquat challenge. On day 15, piglets in basal diet group and diquat-challenged groups were intraperitoneally injected with sterile saline and diquat at 10 mg/kg body weight, respectively. The results showed that GSH supplementation improved growth performance of diquat-injected piglets from days 15 to 18 (p < 0.05), especially at a dose of 100 mg/kg GSH. Meanwhile, diquat also caused oxidative stress and intestinal barrier damage in piglets. However, GSH supplementation enhanced the antioxidant capacity of serum and jejunum, as evidenced by the increase in GSH content and total superoxide dismutase activities and the decrease in 8-hydroxy-2'-deoxyguanosine concentrations (p < 0.05). GSH also up-regulated the mRNA expressions of intestinal tight junction protein (zonula occludens 1, ZO1; occludin, OCLN; claudin-1, CLDN1) and mitochondrial biogenesis and function (peroxisome proliferator-activated receptor-gamma coactivator-1 alpha, PGC1α; mitochondrial transcription factor A, TFAM; cytochrome c, CYCS), compared with diquat-challenged piglets in basal diet (p < 0.05). Thus, the study demonstrates that GSH protects piglets from oxidative stress caused by diquat and 100 mg/kg GSH has a better protective role.

Effect of Hydrogen Oxide-Induced Oxidative Stress on Bone Formation in the Early Embryonic Development Stage of Chicken. Biomolecules 2023; 13:biom13010154. [PMID: 36671539 PMCID: PMC9855391 DOI: 10.3390/biom13010154] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 01/02/2023] [Accepted: 01/09/2023] [Indexed: 01/15/2023] Open
Abstract
The current study aimed to monitor the impact of H2O2-induced oxidative stress on avian bone formation during the early stage of embryonic development. Fertilized Cobb broiler eggs were divided into five treatment groups and micro-injected with varying concentrations of H2O2, i.e., control (PBS; 0 nM), 10 nM, 30 nM, 100 nM, and 300 nM, on embryonic day 3, with continued incubation thereafter. The treatment concentrations were selected based on the level of lipid peroxidation and the survival rate of embryo. Embryos were collected at 6 h, 24 h, 48 h, and 72 h post-injection. The mRNA expression levels of apoptotic markers, antioxidant enzymes, and early bone formation gene markers were measured. The results showed that the microinjection of H2O2 altered the expression pattern of antioxidant enzymes' mRNA during early embryogenesis and decreased the expression of COL1A2 and COL2A1 at 6 h and 24 h post-injection. Decreased expression of BMP, BGLAP, and RUNX2 was observed 48 h post-injection. Additionally, a shorter embryo length was observed in the 100 nM and 300 nM H2O2 treatment groups 72 h post-injection. In conclusion, H2O2-induced oxidative stress suppressed the expression of bone formation gene markers, with chronic effects on avian embryonic development.

Effects of dietary supplementation with chlorogenic acid on growth performance, antioxidant capacity, and hepatic inflammation in broiler chickens subjected to diquat-induced oxidative stress. Poult Sci 2023; 102:102479. [PMID: 36669355 PMCID: PMC9871335 DOI: 10.1016/j.psj.2023.102479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2022] [Revised: 12/19/2022] [Accepted: 01/01/2023] [Indexed: 01/07/2023] Open
Abstract
This study was conducted to investigate the protective effects of chlorogenic acid (CGA) on broilers subjected to (DQ)-induced oxidative stress. In experiment 1, one hundred and ninety-two male one-day-old Ross 308 broiler chicks were distributed into 4 groups and fed a basal diet supplemented with 0, 250, 500, or 1,000 mg/kg CGA for 21 d. In experiment 2, an equivalent number of male one-day-old chicks were allocated to 4 treatments for a 21-d trial: 1) Control group, normal birds fed a basal diet; 2) DQ group, DQ-challenged birds fed a basal diet; and 3) and 4) CGA-treated groups: DQ-challenged birds fed a basal diet supplemented with 500 or 1,000 mg/kg CGA. The intraperitoneal DQ challenge was performed at 20 d. In experiment 1, CGA administration linearly increased 21-d body weight, and weight gain and feed intake during 1 to 21 d (P < 0.05). CGA linearly and/or quadratically increased total antioxidant capacity, catalase, superoxide dismutase, and glutathione peroxidase activities, elevated glutathione level, and reduced malondialdehyde accumulation in serum, liver, and/or jejunum (P < 0.05). In experiment 2, compared with the control group, DQ challenge reduced body weight ratio (P < 0.05), which was reversed by CGA administration (P < 0.05). DQ challenge increased serum total protein level, aspartate aminotransferase activity, and total bilirubin concentration (P < 0.05), which were normalized when supplementing 500 mg/kg and/or 1,000 mg/kg CGA (P < 0.05). DQ administration elevated hepatic interleukin-1β, tumor necrosis factor-α, and interleukin-6 levels (P < 0.05), and the values of interleukin-1β were normalized to control values when supplementing CGA (P < 0.05). DQ injection decreased serum superoxide dismutase activity, hepatic catalase activity, and serum and hepatic glutathione level, but increased malondialdehyde concentration in serum and liver (P < 0.05), and the values of these parameters (except hepatic catalase activity) were reversed by 500 and/or 1,000 mg/kg CGA. The results suggested that CGA could improve growth performance, alleviate oxidative stress, and ameliorate hepatic inflammation in DQ-challenged broilers.

Reduced genotoxicity of lignin-derivable replacements to bisphenol A studied using in silico, in vitro, and in vivo methods. MUTATION RESEARCH. GENETIC TOXICOLOGY AND ENVIRONMENTAL MUTAGENESIS 2023; 885:503577. [PMID: 36669816 DOI: 10.1016/j.mrgentox.2022.503577] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 11/29/2022] [Accepted: 12/07/2022] [Indexed: 12/14/2022]
Abstract
Bisguaiacols, lignin-derivable bisphenols, are considered promising and possibly safer alternatives to bisphenol A (BPA), but comprehensive toxicity investigations are needed to ensure safety. Most toxicity studies of BPA and its analogues have focused on potential estrogenic activity, and only limited toxicological data are available on other toxicity aspects, such as genotoxicity at low exposure levels. In this study, the genotoxicity of six lignin-derivable bisguaiacols with varying regioisomer contents and degrees of methoxy substitution was investigated using a multi-tiered method, consisting of in silico simulations, in vitro Ames tests, and in vivo comet tests. The toxicity estimation software tool, an application that predicts toxicity of chemicals using quantitative structure-activity relationships, calculated that the majority of the lignin-derivable bisguaiacols were non-mutagenic. These results were supported by Ames tests using five tester strains (TA98, TA100, TA102, TA1535, and TA1537) at concentrations ranging from 0.5 pmol/plate to 5 nmol/plate. The potential genotoxicity of bisguaiacols was further evaluated using in vivo comet testing in fetal chicken livers, and in addition to the standard alkaline comet assay, the formamidopyrimidine DNA glycosylase enzyme-modified comet assay was employed to investigate oxidative DNA damage in the liver samples. The oxidative stress analyses indicated that the majority of lignin-derivable analogues showed no signs of mutagenicity (mutagenic index < 1.5) or genotoxicity, in comparison to BPA and bisphenol F, likely due to the methoxy groups on the lignin-derivable aromatics. These findings reinforce the potential of lignin-derivable bisphenols as safer alternatives to BPA.

Effects of different selenium sources on duodenum and jejunum tight junction network and growth performance of broilers in a model of fluorine-induced chronic oxidative stress. Poult Sci 2022; 101:101664. [PMID: 35066382 PMCID: PMC8783152 DOI: 10.1016/j.psj.2021.101664] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Revised: 12/03/2021] [Accepted: 12/09/2021] [Indexed: 02/07/2023] Open
Abstract
The protective effects and underlying molecular mechanisms of sodium selenite (SS) and selenomethionine (SM) against chronic oxidative stress-induced duodenum and jejunum tight junction (TJ) network disturbance and growth inhibition of broilers were investigated in the current experiment. At the age of 1 d, 720 Lingnan Yellow broiler chicks were allocated to 4 experimental diets (with 6 replicates per diet and 30 birds per replicate) and offered either a control diet (fluorine [F] 23 mg/kg, control [CoN] group) or test diets (800 mg/kg F, high F [HF] group; 800 mg/kg F+0.15 mg selenium [Se]/kg as SS [SS group] or SM [SM group]) for 56 d. The results showed that HF group could induce chronic oxidative stress and subsequently increased (P < 0.05) proinflammatory cytokines levels of duodenum and jejunum in comparison with the CoN group. Increased proinflammatory cytokines levels of HF group promoted myosin light chain kinase (MLCK) transcription, thus leading to a decrease (P < 0.05) in TJ proteins expression of duodenum and jejunum when compared with the CoN group. A reduction of TJ proteins expression destroyed the TJ structures in the HF group, which in turn increased intestinal mucosal permeability of duodenum and jejunum and ultimately induced growth inhibition of broilers. Dietary Se supplementation could ameliorate HF-induced duodenum and jejunum TJ network impairment and growth retardation of broilers, potentially by increasing (P < 0.05) the glutathione peroxidase and thioredoxin reductase activities, reducing (P < 0.05) the reactive oxygen species and malondialdehyde levels, regulating the secretion of proinflammatory cytokines, and mediating the transcription level of MLCK in the duodenum and jejunum. Additionally, our data also suggested that the protective effects of SM were superior to those of SS. This study will provide a theoretical basis for developing SM into an efficient protective agent for intestinal mucosal barrier in poultry.

Abstract
In order to evaluate the alleviative effects and molecular mechanisms of sodium selenite (SS) and selenomethionine (SM) on excessive apoptosis induced by high fluorine (HF) in the duodenum and jejunum of broilers, 720 1 day old Lingnan Yellow broilers were randomly divided into 4 groups (each group assigned 180 chickens with 6 replicates) and offered either a control diet or test diets (800 mg/kg F, HF group; 800 mg/kg F + 0.15 mg selenium (Se)/kg as SS (SS group) or SM (SM group)) for 50 days. High F intake significantly increased (P < 0.05) apoptosis rates of duodenum and jejunum by inducing oxidative stress and leading to mitochondrial damage. Selenomethionine supplementation effectively alleviated mitochondrial damage and severe apoptosis of duodenum and jejunum caused by HF through decreasing oxidative stress parameters. Selenomethionine added group significantly increased (P < 0.05) nuclear factor erythroid 2-related factor 2 (Nrf2) mRNA and nuclear Nrf2 protein levels as well as Nrf2 downstream antioxidant enzymes expressions in the duodenum and jejunum when compared with the HF group. Selenomethionine was superior to SS in activating the Nrf2 pathway and reducing the apoptosis rate of duodenum. It was concluded that dietary SM supplementation could ameliorate F-induced excessive apoptosis by inducing the Nrf2 pathway. Our findings will bring a promising tactics for the utilization of SM as an efficient antioxidant additive for reducing the intestinal damage caused by fluorosis in poultry.

Abstract
This study was conducted to investigate the effects of dietary supplementation xylo-oligosaccharides (XOS), coated sodium butyrate (CSB), and their combination on growth performance, immune parameters, and intestinal barrier of broilers. A total of 192 1-day-old chicks were assigned to a 2 × 2 factorial design including two dietary additives (0 and 150 mg/kg XOS and 0 and 400 mg/kg CSB). This trial lasted for 42 days. CSB supplementation increased the thymus and bursa index, blood myeloperoxidase (MPO) activity, and IgG and IgM concentrations, whereas adding XOS only improved IgM concentration (p < .05). A significant interaction was observed for MPO activity. Furthermore, broilers fed CSB and their interaction exhibited increased ileal villus height/crypt depth (VH/CD) and goblet cells numbers in the ileum, as well as decreased ileal CD (p < .05). Broilers fed XOS and CSB individually showed higher ileal VH, the number of goblet cells in the duodenum and jejunum (p < .05). Moreover, XOS and CSB individual supplementation upregulated the expression of claudin3 in the ileum (p < .05). Simultaneously, a significant interaction was found for the ileal expression of claudin3. Overall, XOS and CSB supplementation could improve the development of immune organs, the small intestine morphology, and the intestinal physical barrier of broilers. Although no clear synergy of XOS and CSB was detected, the combination had positively affect broilers intestinal barrier and immune parameters.

Dietary squalene supplementation alleviates diquat-induced oxidative stress and liver damage of broiler chickens. Poult Sci 2020; 100:100919.

Abstract
The aim of this study was to explore the protective effects of squalene supplementation on growth performance, oxidative status, and liver function of diquat-challenged broilers. One hundred forty-four 1-day-old male Ross 308 broiler chicks were allocated to 3 groups, and each group consisted of 6 replicates of 8 birds each. The three groups were as follows: 1) nonchallenged broilers fed with a basal diet (control group), 2) diquat-challenged broilers fed a basal diet, and 3) diquat-challenged broilers fed with a basal diet supplemented with 1.0 g/kg of squalene. Broilers were intraperitoneally injected with 20 mg/mL of diquat solution at a dosage of 1 mL/kg of BW or an equivalent amount of saline at 20 d. Compared with the control group, weight gain and BW change rate during 24 h after injection were decreased by diquat challenge (P < 0.05), and the diquat-induced compromised growth performance was improved by squalene supplementation (P < 0.05). Diquat administration reduced plasma superoxide dismutase activity and increased malondialdehyde accumulation and glutathione peroxidase activity in both plasma and the liver (P < 0.05). In contrast, plasma glutathione peroxidase activity in diquat-challenged broilers was reduced by squalene supplementation (P < 0.05). The hepatic glutathione level was reduced by diquat administration (P < 0.05), whereas its level in plasma and the liver of diquat-challenged broilers was increased by squalene supplementation (P < 0.05). The relative liver weight of broilers was increased by diquat challenge (P < 0.05), with its value being intermediate in the squalene-supplemented group (P > 0.05). The plasma aminotransferase activities and total bilirubin concentration were increased by diquat challenge (P < 0.05), which were reduced by squalene supplementation (P < 0.05). The mRNA abundance of hepatic nuclear factor erythroid 2–related factor 2 (P < 0.05) was upregulated by diquat treatment, regardless of squalene supplementation. The mRNA abundance of hepatic glutathione peroxidase 1 and B-cell lymphoma/leukemia 2–associated X protein was upregulated by diquat challenge (P < 0.05), which was reversed by squalene administration (P < 0.05). Squalene increased NAD(P)H quinone dehydrogenase 1 mRNA abundance and decreased caspase 3 mRNA abundance in the liver of diquat-challenged broilers (P < 0.05). The results suggested that squalene can increase weight gain, improve oxidative status, and alleviate liver injury in diquat-challenged broilers.

Pterostilbene as a protective antioxidant attenuates diquat-induced liver injury and oxidative stress in 21-day-old broiler chickens. Poult Sci 2020; 99:3158-3167. [PMID: 32475452 PMCID: PMC7597657 DOI: 10.1016/j.psj.2020.01.021] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Revised: 12/29/2019] [Accepted: 01/11/2020] [Indexed: 12/27/2022] Open
Abstract
This study investigated the effects of pterostilbene (PT) supplementation on growth performance, hepatic injury, and antioxidant variables in a broiler chicken model with diquat (DQ)-induced oxidative stress. There were 192 one-day-old male Ross 308 broiler chicks randomly allocated to one of two treatment groups: 1) broilers fed a basal diet and 2) broilers fed a diet supplemented with 400 mg/kg PT. At 20 D of age, half of the broilers in each group were intraperitoneally injected with DQ (20 mg per kg BW), whereas the other half were injected with an equivalent amount of sterile saline. Diquat induced a rapid loss of BW (P < 0.001) 24 h post-injection, but dietary PT supplementation improved the BW change of broilers (P = 0.014). Compared with unchallenged controls, the livers of DQ-treated broilers were in severe cellular damage and oxidative stress, with the presence of higher plasma transaminase activities (P < 0.05), a greater number of apoptotic hepatocytes (P < 0.001), and an increased malondialdehyde content (P = 0.007). Pterostilbene supplementation prevented the increases in plasma aspartate aminotransferase activity (P = 0.001), the percentage of hepatocyte apoptosis (P < 0.001), and the hepatic malondialdehyde accumulation (P = 0.011) of the DQ-treated broilers. Regarding the hepatic antioxidant function, PT significantly increased total antioxidant capacity (P = 0.007), superoxide dismutase activity (P = 0.016), reduced glutathione content (P = 0.011), and the ratio of reduced glutathione to oxidized glutathione (P = 0.003), whereas it reduced the concentration of oxidized glutathione (P = 0.017). Pterostilbene also boosted the expression levels of nuclear factor erythroid 2–related factor 2 (P = 0.010), heme oxygenase 1 (P = 0.037), superoxide dismutase 1 (P = 0.014), and the glutamate–cysteine ligase catalytic subunit (P = 0.001), irrespective of DQ challenge. In addition, PT alleviated DQ-induced adenosine triphosphate depletion (P = 0.010). In conclusion, PT attenuates DQ-induced hepatic injury and oxidative stress of broilers presumably by restoring hepatic antioxidant function.
