Preparation of polyclonal antibody against thrombospondin 2 recombinant protein and its functional verification in pulmonary hypertension syndrome in broilers. Int J Biol Macromol 2024; 274:133284. [PMID: 38906344 DOI: 10.1016/j.ijbiomac.2024.133284] [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: 04/26/2024] [Revised: 06/17/2024] [Accepted: 06/18/2024] [Indexed: 06/23/2024]
Abstract
Cell migration regulated by Thrombospondin 2 (THSB2) is important for the development of pulmonary artery remodeling, but the mechanism by which THBS2-mediated cell migration regulates the development of pulmonary artery remodeling in broiler ascites syndrome (AS) is unclear. In addition, the lack of chicken THBS2 antibodies makes it difficult to study the mechanism in depth. In our study, we used recombinant gene technology, protein purification, and other techniques to obtain mouse anti-chicken THBS2 antibody and analyze its expression in broilers, ascites broilers and other animals. The results showed that we immunized mouse with recombinant THBS2 protein and obtained an antibody titer of 1:204,800, and the addition of astragalus polysaccharide as an immunomodulator during immunization significantly increased the titer of the antibody. Western blotting (WB) and immunofluorescence results showed that the THBS2 was significantly down-regulated in the ascites broiler. The THBS2 antibody we prepared can also detect THBS2 protein in duck, mouse, goat, and rabbit tissues. These results provide a foundation for further investigation of the role of THBS2 in pulmonary artery remodeling in broiler ascites syndrome and a powerful tool for studying the role of THBS2 in AS.

Abstract
Receptor interacting protein kinase 3 (RIPK3) is a vital serine/threonine kinase in regulating the programmed destruction of infected cells to defend against RNA viruses. Although the role of RIPK3 in viruses in mice is well characterized, it remains unclear where in nephropathogenic infectious bronchitis virus (NIBV) in chickens. Here, we use a self-prepared polyclonal antibody to clarify the abundance of RIPK3 in tissues and define the contributions of RIPK3 in tissue damage caused by NIBV infection in chickens. Western blot analyses showed that RIPK3 polyclonal antibody can specifically recognize RIPK3 in the vital tissues of Hy-Line brown chicks and RIPK3 protein is abundantly expressed in the liver and kidney. Moreover, NIBV significantly upregulated the expression levels of RIPK3 in the trachea and kidney of chicks in a time-dependent manner. In addition, the activation of necroptosis in response to NIBV infection was demonstrated by the coimmunoprecipitation (CoIP) experiments through RIPK3 in the necrosome, which phosphorylates its downstream mixed-spectrum kinase structural domain-like protein (MLKL). Our findings offered preliminary insights into the key role of RIPK3 protein in studying the underlying mechanism of organ failure caused by NIBV infection.

Abstract
Tumor necrosis factor-α-induced protein eight like 1 (TIPE1) plays important role in autophagy, immunity, and lipid metabolism. The potential role of TIPE1 in fatty liver hemorrhage syndrome (FLHS) is elusory. In the present study, the full-length coding sequence of TIPE1 was cloned, and the polyclonal antibody of TIPE1 was produced by the recombinant TIPE1 protein. The bioinformatic analysis showed that the chicken TIPE1 protein, which was predicted to be a hydrophobic and non-transmembrane protein without signal peptide was highly different from that of mammals. Furthermore, proceeded by using TIPE1 polyclonal antibody, the tissue distribution analysis showed that TIPE1 protein is ubiquitously expressed in various tissues in adult hens and chicks, with its level being higher in the liver and, spleen, moderate in intestinal, brain, and heart. Besides, immunohistochemistry and immunofluorescence observation demonstrated that TIPE1 mainly existed in the cytoplasm in liver, duodenum, and cecum cell. Notably, the TIPE1 expressions were significantly decreased in laying hens suffering from FLHS. Collectively, these results showed that the chicken TIPE1 polyclonal antibody was successfully prepared and further used to analyze the expression profiles of chicken. And the expression of TIPE1 was reduced in FLHS which provided the foundation for further investigation in FLHS.

Abstract
As a novel functional protein, juxtaposed with another zinc finger protein 1 (JAZF1) can regulate the growth and apoptosis through various pathways, and maintain the body's normal physiological metabolism. To explore the important role of JAZF1 in broiler ascites syndrome (BAS), we analysed the expression and distribution of the protein in poultry and mammal tissues based on the prepared polyclonal antibody. In this study, the recombinant plasmid PET32a-JAZF1 was constructed by TA cloning, subcloning and other technical methods, and the fusion protein His-JAZF1 was successfully expressed. After purification, His-JAZF1 was used as the antigen to prepare high-quality chicken-derived antibodies. Subsequently, the results showed that JAZF1 protein in broiler tissues could be specifically recognized by this antibody. Immunofluorescence showed that JAZF1 protein mainly exists in the cytoplasm of pulmonary artery, liver, kidney, heart and lung tissue cells of various animals. The expression of this protein was more obvious in broiler and duck tissues than in mammalian tissues. In addition, western blotting combined with immunofluorescence showed that BAS caused a significant decrease in JAZF1 protein in tissue cells. This effect further indicated that JAZF1 protein was closely related to the occurrence of BAS and provided a new entry point for the functional study of JAZF1 protein.

Xi Y, Huang Y, Li Y, Huang Y, Yan J, Shi Z. The effects of dietary protein and fiber levels on growth performance, gout occurrence, intestinal microbial communities, and immunoregulation in the gut-kidney axis of goslings. Poult Sci 2022; 101:101780. [PMID: 35325834 PMCID: PMC8938869 DOI: 10.1016/j.psj.2022.101780] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 01/29/2022] [Accepted: 02/05/2022] [Indexed: 02/06/2023] Open
Abstract
The current study evaluated the effects of dietary protein and fiber levels on growth performance, gout occurrence, intestinal microbial communities, and immunoregulation in the gut-kidney axis of goslings. A completely randomized 2 × 3 factorial design was adopted with 2 CP levels (180 [18CP] and 220 [22CP] g/kg) and 3 crude fiber (CF) levels (30 [low CF], 50 [mid CF], and 70 [high CF] g/kg). The high CP or low CF diets predisposed the goslings to gout. The high protein diets worsened renal function; serum concentrations of UA and Cr as well as XOD activity in 9-day-old goslings fed 22% CP diets were significantly increased. Although CF levels from 3 to 7% did not directly affect kidney health, increasing CF levels might accelerate the increase of probiotics in the cecum of goslings and withhold maleficent bacteria, alleviating the gut dysbiosis caused by high protein diets. An analysis of the cecal microbiota via 16Sr RNA sequencing revealed that the abundance of Enterococcus in the 22CP group was higher than that in the 18CP group but decreased with increasing CF levels on d 9. The abundance of Lactobacillus increased with increasing CF levels. Additionally, higher serum LPS and proinflammatory cytokine concentrations and upregulated mRNA expression levels in the cecal, tonsil, and kidney tissues indicated that high-protein diets could activate the TLR4/MyD88/NFκB pathway and induce both intestinal and renal inflammation in young goslings. Serum LPS concentrations on d 9 were found to decrease with increasing CF, although altering dietary CF levels did not directly affect the serum immune indices of goslings. In conclusion, the high CP diet exerted a negative effect on gout occurrence, microbial communities, and immunoregulation in the gut-kidney axis of goslings, while appropriately increased dietary fiber levels helped maintain intestinal balance and reduced serum LPS concentration. We propose a diet of 18% CP paired with a 5% CF as the optimal combination for gosling feed.

Abstract
RPS14 (ribosomal protein S14) gene maintains the normal physiological activities of the body by regulating the biosynthesis of ribosomes and the translation of important proteins. This study aims to explore the potential role of RPS14 in broiler ascites syndrome (BAS). We successfully prepared polyclonal antibody against RPS14 and studied the localization and expression of RPS14 protein in a variety of animal key tissues. In this experiment, the recombinant expression plasmid PET28a-RPS14 was constructed using the prokaryotic expression technology of foreign genes. Under the conditions of IPTG induction, a His-RPS14 protein with a molecular weight of about 22 kDa was expressed, and the purified recombinant protein was used as an antigen to prepare rabbit anti-chicken serum. Western blot results showed that the serum could specifically identify RPS14 protein in important tissues of broilers. Immunofluorescence combined with homology analysis showed that the antiserum had significant species specificity. Compared with other species, the expression of this protein in key tissues of broilers and ducks was more significant. More importantly, western blotting and immunofluorescence showed that BAS significantly reduced the expression level of RPS14. This further indicated that RPS14 protein can be used as one of the important entry points for BAS research.

Abstract
Peroxisome proliferator-activated receptor α (PPARα) play a key role in the regulation of metabolic homeostasis, inflammation, cellular growth, and differentiation. To further explore the potential role of PPARα in the energy homeostasis of fatty liver hemorrhagic syndrome (FLHS), we reported the prokaryotic expression and purification of chicken PPARα subunit protein, and successfully prepared a polyclonal antibody against PPARα recombinant protein. The 987 bp PPARα subunit genes were cloned into the pEASY-T3 clone vector. Then the plasmid PCR products encoding 329 amino acids were ligated to pEASY-Blunt E2 vector and transformed into BL21 to induce expression. The recombinant PPARα subunit protein, containing His-tag, was purified by affinity column chromatography using Ni-NTA affinity column. Rabbit antiserum was generated by using the concentration of recombinant PPARα subunit protein as the antigen. The results of western blotting showed that the antiserum can specifically recognize chicken endogenous PPARα protein. Immunohistochemistry and immunofluorescence showed that the PPARα mainly existed in the nucleus of hepatocytes, renal epithelial cells and hypothalamic endocrine nerve cells. More importantly, western blotting and real-time quantitative PCR indicated that FLHS significantly decreased the expression of PPARα.

Abstract
Liver kinase B1 (LKB1) is a member of the serine/threonine kinase family, which plays an indispensable role in the organism of animals. In the current study, the chicken LKB1 protein gene was amplified by PCR based on the primers and cDNA templates. Then, the cloning vector was constructed and the target gene was cloned. After that, the target gene was inserted into the expression vector to construct the recombinant plasmid. The recombinant plasmid was transformed into BL21 (DE3) host cells and the LKB1 recombinant proteins were successfully expressed by using Isopropyl-β-D-thiogalactopyranoside (IPTG). Finally, purified LKB1 proteins were used as antigen and the rabbit-derived antiserums were collected. The antiserum titer determined by ELISA was not less than 1:128000. The results of Western blot suggested that the polyclonal antibody is highly specific to chicken LKB1 protein. Immunofluorescence indicated that the LKB1 protein is mainly expressed in the cytoplasm of liver, heart and hypothalamus cells of chicken. Our study showed that the LKB1 polyclonal antibodies produced by this method are effective and can be used to further study the role of LKB1 in the pathogenesis of chicken disease.

Fermented Feed Supplement Relieves Caecal Microbiota Dysbiosis and Kidney Injury Caused by High-Protein Diet in the Development of Gosling Gout. Animals (Basel) 2020; 10:ani10112139.

Abstract
Firstly, forty-eight 1-day-old goslings were randomly allocated to four groups and were fed diets containing crude protein (CP) at different concentrations: 160, 180, 200, and 220 g/kg in Experiment One. We found a dose-dependent relationship between the dietary protein levels and morbidity of gosling gout. The concentration of serum uric acid (UA), creatinine (Cr), and urea nitrogen (UN), and the activity of xanthine oxidase in the 220CP groups were significantly higher than those in the low-protein diet groups. Beneficial microbes, including Akkermansia, Lactococcus, and Butyricicoccus were enriched in the ceca of healthy goslings, while the microbes Enterococcus, Enterobacteriaceae, and Bacteroides were enriched in those with gout. Then, we explored the effects of fermented feed on gosling gout caused by high-protein diets in Experiment Two. A total of 720 1-day-old goslings were randomly allotted to four experimental groups: CN (162.9 g/kg CP), CNF (167.5 g/kg CP, replacing 50 g/kg of the basal diet with fermented feed), HP (229.7 g/kg CP, a high-protein diet), and HPF (230.7 g/kg CP, replacing 50 g/kg of the high-protein diet with fermented feed). We found that the cumulative incidence of gout increased in the HP group compared with that in the control, but decreased in the HPF group compared to that in the HP group. Similarly, the concentration of serum UA in the HP group was higher than that in the CN group, but decreased in the HPF group. Meanwhile, compared with the HP group, using fermented feed in diets decreased the abundance of Enterococcus in the ceca of goslings, while increasing the abundance of Lactobacillus. These results suggest that appropriate dietary protein levels and the fermented feed supplement might relieve the kidney injury and gut microbiota dysbiosis caused by high-protein diets in the development of gosling gout.

Abstract
The gout disease is spreading worldwide and its drug target is the human xanthine oxidase. Through this work, we investigated the inhibitory effect of the ten lanthanide(III) complexes of biologically active bis-coumarins on xanthine oxidase. We achieved molecular docking studies using GOLD software to study the formed interactions in the enzyme-inhibitor complex. The results confirm the inhibitory effect of the lanthanide complexes showing the best Nd(III) complex with IC50 of 12.91 nM. The docking results confirm this inhibition. We saved nearly the same interactions between the two inhibitors allopurinol and the Nd(III) complex according to the docking results. No further studies have been found in this context. The ADMET analysis show that the three complexes are nontoxic.Communicated by Ramaswamy H. Sarma.

Abstract
1.The objective of the experiment was to analyse serum profiles of goslings with visceral gout and compare them with those of healthy individuals to identify differentially-abundant metabolites as potential biomarkers. 2.Untargeted gas chromatography and time-of-flight mass spectrometry (GC-TOF-MS) metabolomic profiling was used to compare the serum metabolome of 15 goslings (Anser cygnoides) with gout and 15 healthy goslings (control). 3.Goslings with gout had a metabolic profile distinct from that of the controls, with 45 metabolite levels differing significantly (VIP > 1; P < 0.05) between both groups. Nine metabolites (hydrocortisone, glucose, trans-4-hydroxy-L-proline, galactose, 2-deoxy-D-galactose, beta-mannosylglycerate, d-glucoheptose, zymosterol, and hypoxanthine) were selected through receiver operating characteristics (ROC) analysis (area under curve (AUC) score ≥0.85) as potential biomarkers. Pathway analysis revealed that metabolites with differing levels were mainly involved in galactose, arginine and proline and purine metabolisms. 4.These results provided new insights into the pathogenesis of gout. Increased xanthine and hypoxanthine with decreased hydrocortisone provide promising biomarkers for gosling gout diagnosis. The findings suggested that hepatic metabolic disorders frequently occur in the development of avian gout.

Xi Y, Yan J, Li M, Ying S, Shi Z. Gut microbiota dysbiosis increases the risk of visceral gout in goslings through translocation of gut-derived lipopolysaccharide. Poult Sci 2020; 98:5361-5373. [PMID: 31250018 DOI: 10.3382/ps/pez357] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2019] [Accepted: 06/03/2019] [Indexed: 12/22/2022] Open
Abstract
We investigated the gut-kidney interaction in goslings with gout and tried to decipher the probable mechanisms through which gut dysbiosis leads to the progression of renal injury and inflammation. A total of 15 goslings (Anser cygnoides), with typical visceral gout symptoms, were screened and compared with 15 healthy goslings. We determined the signatures of the microbiome in the cecum chyme of goslings in the 2 groups by 16S sequencing, and analyzed the changes in intestinal permeability, levels of serum lipopolysaccharide (LPS), and the induced inflammatory response of Toll-like receptors (TLRs). We found the existence of gut dysbiosis in goslings with gout as a result of interactions among the multitude of bacteria present in the gut, and the proliferation of a specific pathogenic genus, Proteobacteria, played a decisive role in this process. Moreover, the permeability increased not only in the intestinal epithelium but also in the renal endothelium, providing possibilities for gut-derived LPS to enter the blood circulation and damage the kidneys. The systemic LPS concentration was increased in the gout group and exhibited a positive correlation with the degree of renal injury. In addition, we also found that inflammatory disorders concurrently existed in the gut and kidney of goslings with gout, and the LPS/TLR4/MyD88 (Myeloid differentiation primary response gene 88) inflammatory signaling was activated. These results indicate that the loss of intestinal barrier as a result of gut dysbiosis causes the translocation of gut-derived LPS, which can play an important role in the development of gout in goslings through interference with kidney functions.
