Abstract
Immunogenic, methionine copper-induced response had proven to be precedent in providing resistance against certain diseases in fish. This study allocates the fitness strategy for Oreochromis niloticus by introducing and incorporating the well-designed, stabilized, and biocompatible N-carbamoyl-methionine copper (NCM-Cu) as a Cu potent source in diet that enhances the bioavailability and fitness. The synchronized NCM-Cu complex was characterized by directing ultraviolet and visible spectrophotometry (UV-vis), Fourier-transform infrared (FTIR), X-ray diffractometry (XRD), thermogravimetric analysis (TGA), and single-crystal X-ray diffraction. Results revealed blue columnar crystalline, NCM-Cu complex with an empirical formula as C12H30CuN4O10S2. Anonymously, the overall growth performance of the fish remained unaltered with NCM-Cu adjunct feed. NCM-Cu significantly raised the Cu accumulation in the fish muscles, liver, gill, and intestine in contrast to the basic Cu-rich feed. The serum antioxidant enzyme activity elevated up to (ceruloplasmin: 19.38 U/L) and the lowest liver malondialdehyde (MDA) content (8.81 nmol/mg prot.) and triglyceride content (0.39 nmol/g prot.) were observed in the NCM-Cu group as compared to the basic Cu and CuSO4 groups, suggesting that NCM-Cu promoted antioxidative responses and alleviated lipid peroxidation of O. niloticus. Overweening, the synthesized complex, NCM-Cu significantly regulated the expression levels of lysozyme, immunoglobulin M, complement 4, and complement 3 up to 10.93 U/mL, 0.72, 0.77, and 1.18 mg/mL in serum, respectively. Thus, such endorsed results reveal the preeminence of NCM-Cu-supplemented diet for the fitness in O. niloticus.

Sun L, Xue Y, Peng C, Xu C, Shi J. Influence of sulfur fertilization on CuO nanoparticles migration and transformation in soil pore water from the rice (Oryza sativa L.) rhizosphere. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2020; 257:113608. [PMID: 31761580 DOI: 10.1016/j.envpol.2019.113608] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/31/2019] [Revised: 10/15/2019] [Accepted: 11/10/2019] [Indexed: 06/10/2023]
Abstract
The biogeochemical cycling of sulfur in soil is closely associated with the mobility and bioavailability of heavy metals; however the influence of sulfur on the behavior of metal-based nanoparticles has not yet been studied. The influence of S fertilizer (S0 and Na2SO4) applied in paddy soils on CuO NPs behavior in soil pore water was explored in the present study. Synchrotron-based techniques were applied to investigate the migration and speciation transformation of CuO NPs in soil pore water colloids. The application of sulfur fertilizer increased the zeta potential of soil colloids from the rice rhizosphere region and reduced the size of the colloids. Sulfur fertilization decreased the concentration of Cu in soil pore water in the rice rhizosphere region. S0 fertilizer reduced the Cu concentration in soil colloids (by 55.8%-73.5%), while Na2SO4 increased the Cu concentration in soil colloids (by 173.8%-265.1%). Sulfur fertilization changed the spatial distribution of Fe3+ and Cu2+ in colloids, making these ions more likely to be aggregated on the edges of soil colloids. Speciation transformation of CuO NPs happened during the process of migration. The main Cu speciation in the soil colloids were CuO NPs, Cu-Cysteine, Cu2S and Cu-Citrate. Sulfur fertilization increased the proportion of Cu2S (by 40.5%) in soil pore water colloids from the rice rhizosphere region, while the proportion of CuO NPs was reduced (by 18.4%). Sulfur fertilization changed the morphology and elementary composition of colloids in soil pore water, thus influencing the migration of CuO NPs in the soil column through soil colloids.

Cloning, expression pattern, and potential role of MAPKp38 and NF-κBp65 in response to lipopolysaccharide in yellow catfish ( Pelteobagrus fulvidraco). ACTA ACUST UNITED AC 2020; 5:416-423.

Abstract
Mitogen-activated protein kinases (MAPK) and nuclear factor kappa B (NF-κB) pathways are considered to be two crucial intracellular signaling cascades in pro-inflammatory responses. In this study, we reported the coding sequences (CDS) of MAPKp38 and NF-κBp65 from yellow catfish. We also investigated the gene structure, expression patterns and functional role in yellow catfish. The CDS of MAPKp38 is 1,086 bp encoding 361 amino acids (AA). The MAPKp38 protein has a long highly conserved serine/threonine protein kinases catalytic domain. The NF-κBp65 CDS is 1,794 bp, and the gene encodes 597 AA, with a Rel homology domain (RHD) which consists of a RHD-DNA-binding domain and an Ig-like, plexins, transcription factors (IPT) domain. Moreover, MAPKp38 and NF-κBp65 protein of bony fish and other vertebrates have a single clade. Quantitative real-time PCR analysis revealed the presence of the MAPKp38 and NF-κBp65 transcript in 12 tissues of healthy yellow catfish. The highest expression levels of MAPKp38 and NF-κBp65 were detected in the heart and liver, respectively. Upon stimulation with an intraperitoneal injection of lipopolysaccharide (LPS), the expression levels of MAPKp38 and NF-κBp65 were up-regulated in the intestine. These results indicated that MAPKp38 and NF-κBp65 play important roles in mediating the response protection against LPS in yellow catfish.

Abstract
Peroxisome proliferator-activated receptor beta (PPARβ) is a ligand-activated transcription factor that plays critical roles in the regulation of many important physiological processes. In this study, PPARβ was cloned and characterized in yellow catfish Pelteobagrus fulvidraco. PPARβ cDNA was 2350 bp in length with an open reading frame (ORF) of 1530 bp, encoding 509 amino acids, a 5'-untranslated region (UTR) of 474 bp, and a 3'-UTR of 346 bp. Similar to mammals, PPARβ protein was predicted to consist of four domains, the A/B domain, DNA-binding domain (DBD), D domain, and ligand-binding domain (LBD). The DBD contained two zinc fingers with eight conserved cysteine residues. The predicted secondary structure of LBD consisted of 12 highly conserved α-helices and a small β-sheet of 4 strands. In addition, PPARβ was widely expressed across the tested tissues (liver, heart, muscle, intestine, brain, spleen, kidney, fat, ovary, and gill), but at the variable levels. Furthermore, the transcriptional responses of PPARβ by dietary Cu and Zn levels were also investigated. Dietary Cu levels showed no significant effects on PPARβ mRNA levels in the liver and intestine; in contrast, dietary Zn levels upregulated the hepatic PPARβ mRNA levels, but not in the intestine. The present study serves to increase our understanding into the function of the PPARβ gene in fish.

Structure and Functional Analysis of Promoters from Two Liver Isoforms of CPT I in Grass Carp Ctenopharyngodon idella. Int J Mol Sci 2017; 18:ijms18112405.

Abstract
Carnitine palmitoyltransferase I (CPT I) is a key enzyme involved in the regulation of lipid metabolism and fatty acid β-oxidation. To understand the transcriptional mechanism of CPT Iα1b and CPT Iα2a genes, we cloned the 2695-bp and 2631-bp regions of CPT Iα1b and CPT Iα2a promoters of grass carp (Ctenopharyngodon idella), respectively, and explored the structure and functional characteristics of these promoters. CPT Iα1b had two transcription start sites (TSSs), while CPT Iα2a had only one TSS. DNase I foot printing showed that the CPT Iα1b promoter was AT-rich and TATA-less, and mediated basal transcription through an initiator (INR)-independent mechanism. Bioinformatics analysis indicated that specificity protein 1 (Sp1) and nuclear factor Y (NF-Y) played potential important roles in driving basal expression of CPT Iα2a gene. In HepG2 and HEK293 cells, progressive deletion analysis indicated that several regions contained cis-elements controlling the transcription of the CPT Iα1b and CPT Iα2a genes. Moreover, some transcription factors, such as thyroid hormone receptor (TR), hepatocyte nuclear factor 4 (HNF4) and peroxisome proliferator-activated receptor (PPAR) family, were all identified on the CPT Iα1b and CPT Iα2a promoters. The TRα binding sites were only identified on CPT Iα1b promoter, while TRβ binding sites were only identified on CPT Iα2a promoter, suggesting that the transcription of CPT Iα1b and CPT Iα2a was regulated by a different mechanism. Site-mutation and electrophoretic mobility-shift assay (EMSA) revealed that fenofibrate-induced PPARα activation did not bind with predicted PPARα binding sites of CPT I promoters. Additionally, PPARα was not the only member of PPAR family regulating CPT I expression, and PPARγ also regulated the CPT I expression. All of these results provided new insights into the mechanisms for transcriptional regulation of CPT I genes in fish.
