| 3 | Calcium overload and reactive oxygen species accumulation induced by selenium deficiency promote autophagy in swine small intestine显示文摘Selenium(Se)deficiency can seriously affect the small intestine of swine,and cause diarrhea in swine.However,the specific mechanism of Se deficiency-induced swine diarrhea has rarely been reported.Here,to explore the damage of Se deficiency on the calcium homeostasis and autophagy mechanism of swine,in vivo and in vitro models of swine intestinal Se deficiency were established.Twenty-four pure line castrated male Yorkshire pigs(45 d old,12.50±1.32 kg,12 full-sibling pairs)were divided into 2 equal groups and fed Se-deficient diet(0.007 mg Se/kg)as the Se-deficiency group,or fed Se-adequate diet(0.3 mg Se/kg)as the control group for 16 weeks.The intestinal porcine enterocyte cell line(IPEC-J2)was divided into 2 groups,and cultured by Se-deficient medium as the Se-deficient group,or cultured by normal medium as the control group.Morphological observations showed that compared with the control group,intestinal cells in the Se-deficiency group were significantly damaged,and autophagosomes increased.Autophagy staining and cytoplasmic calcium staining results showed that in the Sedeficiency group,autophagy increased and calcium homeostasis was destroyed.According to the reactive oxygen species(ROS)staining results,the percentage of ROS in the Se-deficiency group was higher than that in the control group in the in vitro model.Compared with the control group,the protein and mRNA expressions of autophagy-calcium-related genes including Beclin 1,microtubule-associated proteins 1 A(LC3-1),microtubule-associated proteins 1 B(LC3-2),autophagy-related protein 5(ATG5),autophagy-related protein 12(ATG12),autophagy-related protein 16(ATG16),mammalian target of rapamycin(mTOR),calmodulin-dependent protein kinase kinaseβ(CAMKK-β),adenosine 5’-monophosphate-activated protein kinase(AMPK),sarco(endo)plasmic reticulum Ca2+-ATPase(SERCA),and calpain in the Se-deficiency group were significantly increased which was consistent in vivo and in vitro(P<0.05).Altogether,our results indicated that Se deficiency could destroy the calcium homeostasis of the swine small intestine to trigger cell autophagy and oxidative stress,which was helpful to explain the mechanism of Se deficiency-induced diarrhea in swine. | Yingying Zheng Haoyue Guan Jie Yang Jingzeng Cai Qi Liu Ziwei Zhang | 2021 | Animal Nutrition2021,,4: | 0 |
| 4 | Protective effects of 3′-daidzein sulfonate sodium on chronic hepatic injury by regulating the T lymphocyte subsets in mice显示文摘OBJECTIVE To explore the protective effects of 3′-daidzein sulfonate sodium on chronic hepatic injury induced by carbon tetrachloride(CCl4)in mice and investigate the mechanism about regulating the T lymphocyte subsets.METHODS Healthy Kunming male mice were randomly divided in 5groups:control group,model group,bifendate positive control group(2.5mg·kg-1),low and high dose 3′-daidzein sulfonate sodium groups(0.1and 0.3mg·kg-1).The chronic hepatic injury mice were made by intraperitoneal injection of 10% CCl4 plant oil solution twice a week,and sustained for six weeks.At the same time,the mice were treated with normal saline,bifendate(2.5mg·kg-1)and 3′-daidzein sulfonate sodium(0.1and 0.3mg·kg-1),respectively by ig administration once a day and continued for six weeks.After the last administration,the mice blood and liver were taken.Using automatic biochemical analyzer survey the activity of aspartate aminotransferase(AST)and alanine aminotransferase(ALT)in serum.Flow cytometry was used to detect T lymphocyte subsets,enzymes analysis technique was used to observe the liver function(CD3+,CD4+and CD8+),HemateinEosin stain was used to explore the changes in liver morphology.RESULTS The level of ALT and AST in the serum in model group mice increased significantly.While the level of ALT and AST in the serum in 3′-daidzein sulfonate sodium(0.1 or 0.3mg·kg-1,ig)groups mice decreased compared with the model group(P<0.05).And compared with the model group,the ratios of CD3+,CD4-CD8-and CD4+/CD8+ decreased,and the ratios of CD8+ increased in 3′-daidzein sulfonate sodium groups(0.1 and 0.3mg·kg-1,ig;P<0.05).CONCLUSION 3′-daidzein sulfonate sodium have a protective effect on CCl4-induced liver injury mice,and it can result in the changes of T lymphocyte subsets,which may be one of the factors leading to hepatic injury by CCl4. | JingZENG Rui-zhenLIU Gui-linWEI Liang-dongLI Zhi-huaHUANG | 2015 | 中国药理学与毒理学杂志2015,29,S1: | 0 |
| 5 | Role of selenoprotein M knockdown in the melatonin antagonism of nickel-induced apoptosis and endoplasmic reticulum stress in mouse heart显示文摘The aim of this study was to investigate the role of selenoprotein M(SelM)in endoplasmic reticulum stress and apoptosis in nickel-exposed mouse hearts and to explore the detoxifying effects of melatonin.At 21 d after intraperitoneal injection of nickel chloride(NiCl_(2))and/or melatonin into male wild-type(WT)and SelM knockout(KO)C57BL/6J mice,NiCl_(2)was found to induce changes in the microstructure and ultrastructure of the hearts of both WT and SelM KO mice,which were caused by oxidative stress,endoplasmic reticulum stress,and apoptosis,as evidenced by decreases in malondialdehyde(MDA)content and total antioxidant capacity(T-AOC)activity.Changes in the messenger RNA(mRNA)and protein expression of genes related to endoplasmic reticulum stress(activating transcription factor 4(ATF4),inositol-requiring protein 1(IRE1),c-Jun N-terminal kinase(JNK),and C/EBP homologous protein(CHOP))and apoptosis(B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),Caspase-3,Caspase-9,and Caspase-12)were also observed.Notably,the observed damage was worse in SelM KO mice.Furthermore,melatonin alleviated the heart injury caused by NiCl_(2)in WT mice but could not exert a good protective effect in the heart of SelM KO mice.Overall,the findings suggested that the antioxidant capacity of SelM,as well as its modulation of endoplasmic reticulum stress and apoptosis,plays important roles in nickel-induced heart injury. | Xintong ZHANG Xiaoxue GAI Lihua XU Wenxue MA Qiaohan LIU Bendong SHI Cheng FANG Jingzeng CAI Ziwei ZHANG | 2023 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023,24,5: | 0 |
| 6 | Enhanced H_(2) permeation and CO_(2) tolerance of self-assembled ceramic-metal-ceramic BZCYYb-Ni-CeO_(2) hybrid membrane for hydrogen separation显示文摘Perovskite-type mixed protonic-electronic conducting membranes have attracted attention because of their ability to separate and purify hydrogen from a mixture of gases generated by industrial-scale steam reforming based on an ion diffusion mechanism.Exploring cost-effective membrane materials that can achieve both high H_(2) permeability and strong CO_(2)-tolerant chemical stability has been a major challenge for industrial applications.Herein,we constructed a triple phase(ceramic-metal-ceramic)membrane composed of a perovskite ceramic phase BaZr_(0.1)Ce_(0.7)Y_(0.1)Yb_(0.1)O_(3-δ)(BZCYYb),Ni metal phase and a fluorite ceramic phase CeO_(2).Under H_(2) atmosphere,Ni metal in-situ exsolved from the oxide grains,and decorated the grain surface and boundary,thus the electronic conductivity and hydrogen separation performance can be promoted.The BZCYYbNi-CeO_(2)hybrid membrane achieved an exceptional hydrogen separation performance of 0.53 mL min^(-1)cm^(-2) at 800℃ under a 10 vol% H_(2) atmosphere,surpassing all other perovskite membranes reported to date.Furthermore,the CeO_(2) phase incorporated into the BZCYYb-Ni effectively improved the CO_(2)-tolerant chemical stability.The BZCYYbNi-CeO_(2) membrane exhibited outstanding long-term stability for at least 80 h at 700℃ under 10 vol%CO_(2)-10 vol%H_(2).The success of hybrid membrane construction creates a new direction for simultaneously improving their hydrogen separation performance and CO_(2) resistance stability. | Jianqiu Zhu Jingzeng Cui Yuxuan Zhang Ze Liu Chuan Zhou Susu Bi Jingyuan Ma Jing Zhou Zhiwei Hu Tao Liu Zhi Li Xiangyong Zhao Jian-Qiang Wang Linjuan Zhang | 2023 | Journal of Energy Chemistry2023,,7: | 0 |
