Bueno-Silva B, Rosalen PL, Alencar SM, Mayer MPA. Vestitol drives LPS-activated macrophages into M2 phenotype through modulation of NF-κB pathway. Int Immunopharmacol 2020; 82:106329. [PMID: 32114412 DOI: 10.1016/j.intimp.2020.106329] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Revised: 02/15/2020] [Accepted: 02/15/2020] [Indexed: 12/12/2022]
Abstract
Previously, we demonstrated the anti-inflammatory properties of vestitol in a neutrophil model. Here, we show the effects of vestitol on macrophage activation and function. Vestitol was obtained from Brazilian red propolis after bioguided fractionation and tested at different concentrations in LPS-activated RAW 264.7 murine macrophages for nitric oxide (NO) production and cell viability. The levels of TNF-α, IL1-β, TGF-β, IL-4, IL-6, IL-10, IL-12, GM-CSF, IFN-ɣ and gene expression related to cytokines, NO, PI3K-AKT and signal transduction pathways were assayed by ELISA and RT-qPCR, respectively. Differences were determined by one-way ANOVA followed by Tukey-Kramer. Vestitol inhibited NO production by 83% at 0.55 μM without affecting cell viability when compared to the vehicle control (P < 0.05). Treatment with vestitol reduced GM-CSF, IL-6, TNF-α, IL-4 and TGF-β levels and increased IL-10 release (P < 0.05). Vestitol affected the expression of genes related to NF-κB pathway, NO synthase, and inhibition of leukocyte transmigration, namely: Ccs, Ccng1, Calm1, Tnfsf15, Il11, Gata3, Gadd45b, Cdkn1b, Csf1, Ccl5, Birc3 (negatively regulated), and Igf1 (positively regulated). Vestitol diminished the activation of NF-κB and Erk 1/2 pathways and induced macrophages into M2-like polarization. The modulatory effects of vestitol are due to inhibition of NF-κB and Erk 1/2 signaling pathways, which are associated with the production of pro-inflammatory factors.

Abstract
Application of yeast is increasing to improve welfare and promotes growth in aquaculture. The halotolerant yeast Debaryomyces hansenii is normally a non-pathogenic yeast with probiotic properties and potential source of antioxidant enzymes as superoxide dismutase. Here, first, we characterized the sequence features of MnSOD and icCu/ZnSOD from Pacific red snapper, and second, we evaluated the potential antioxidant immune responses of the marine yeast Debaryomyces hansenii strain CBS004 in leukocytes which were then subjected to Vibrio parahaemolyticus infection. In silico analysis revealed that LpMnSOD consisted of 1186 bp, with an ORF of 678 bp encoding a 225 amino acid protein and LpicCu/ZnSOD consisted of 1090 bp in length with an ORF of 465 bp encoding a 154 amino acid protein. Multiple alignment analyzes revealed many conserved regions and active sites among its orthologs. In vitro assays using head-kidney and spleen leukocytes immunostimulated with D. hansenii and zymosan in response to V. parahaemolyticus infection reveled that D. hansenii strain CBS004 significantly increased transcriptions of MnSOD and icCu/ZnSOD genes. Flow cytometry assay showed that D. hansenii was able to inhibit apoptosis caused by V. parahaemolyticus in the Pacific red snapper leukocytes and enhanced the phagocytic capacity in head-kidney leukocytes. Immunological assays reveled an increased in superoxide dismutase and peroxidase activities, as well as, in nitric oxide production and reactive oxygen species production (respiratory burst) in fish stimulated with D. hansenii. Finally, our results. These results strongly support the idea that marine yeast Debaryomyces hansenii strain CBS004 can stimulate the antioxidant immune mechanism in head-kidney and spleen leukocytes.

Abstract
Copper/zinc superoxide dismutases (Cu/ZnSODs) play important roles in improving banana resistance to adverse conditions, but their activities depend on the copper chaperone for superoxide dismutase (CCS) delivering copper to them. However, little is known about CCS in monocots and under stress conditions. Here, a novel CCS gene (MaCCS) was obtained from a banana using reverse transcription PCR and rapid-amplification of cDNA ends (RACE) PCR. Sequence analyses showed that MaCCS has typical CCS domains and a conserved gene structure like other plant CCSs. Alternative transcription start sites (ATSSs) and alternative polyadenylation contribute to the mRNA diversity of MaCCS. ATSSs in MaCCS resulted in one open reading frame containing two in-frame start codons to form two protein versions, which is supported by the MaCCS subcellular localization of in both cytosol and chloroplasts. Furthermore, MaCCS promoter was found to contain many cis-elements associated with abiotic and hormonal responses. Quantitative real-time PCR analysis showed that MaCCS was expressed in all tested tissues (leaves, pseudostems and roots). In addition, MaCCS expression was significantly induced by light, heat, drought, abscisic acid and indole-3-acetic acid, but inhibited by relatively high concentrations of CuSO₄ and under cold treatment, which suggests that MaCCS is involved in abiotic and hormonal responses.

Molecular cloning and characterization of Siamese crocodile (Crocodylus siamensis) copper, zinc superoxide dismutase (CSI-Cu,Zn-SOD) gene. Comp Biochem Physiol A Mol Integr Physiol 2015; 191:187-195. [PMID: 26523498 DOI: 10.1016/j.cbpa.2015.10.028] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2015] [Revised: 10/24/2015] [Accepted: 10/28/2015] [Indexed: 02/07/2023]
Abstract
Superoxide dismutase (SOD, EC 1.15.1.1) is an antioxidant enzyme found in all living cells. It regulates oxidative stress by breaking down superoxide radicals to oxygen and hydrogen peroxide. A gene coding for Cu,Zn-SOD was cloned and characterized from Siamese crocodile (Crocodylus siamensis; CSI). The full-length expressed sequence tag (EST) of this Cu,Zn-SOD gene (designated as CSI-Cu,Zn-SOD) contained 462bp encoding a protein of 154 amino acids without signal peptides, indicated as intracellular CSI-Cu,Zn-SOD. This agreed with the results from the phylogenetic tree, which indicated that CSI-Cu,Zn-SOD belonged to the intracellular Cu,Zn-SOD. Chromosomal location determined that the CSI-Cu,Zn-SOD was localized to the proximal region of the Siamese crocodile chromosome 1p. Several highly conserved motifs, two conserved signature sequences (GFHVHEFGDNT and GNAGGRLACGVI), and conserved amino acid residues for binding copper and zinc (His(47), His(49), His(64), His(72), His(81), Asp(84), and His(120)) were also identified in CSI-Cu,Zn-SOD. Real-time PCR analysis showed that CSI-Cu,Zn-SOD mRNA was expressed in all the tissues examined (liver, pancreas, lung, kidney, heart, and whole blood), which suggests a constitutively expressed gene in these tissues. Expression of the gene in Escherichia coli cells followed by purification yielded a recombinant CSI-Cu,Zn-SOD, with Km and Vmax values of 6.075mM xanthine and 1.4×10(-3)mmolmin(-1)mg(-1), respectively. This Vmax value was 40 times lower than native Cu,Zn-SOD (56×10(-3)mmolmin(-1)mg(-1)), extracted from crocodile erythrocytes. This suggests that cofactors, protein folding properties, or post-translational modifications were lost during the protein purification process, leading to a reduction in the rate of enzyme activity in bacterial expression of CSI-Cu,Zn-SOD.

Abstract
Histidine-proline-rich glycoprotein (HPRG), or histidine-rich glycoprotein (HRG), is a serum protein that is synthesized in the liver and is actively internalised by different cells, including skeletal muscle. The multidomain arrangement of HPRG comprises two modules at the N-terminus that are homologous to cystatin but void of cysteine proteinase inhibitor function, and a second half consisting of a histidine-proline-rich region (HPRR) located between two proline-rich regions (PRR1 and PRR2), and a C-terminus domain. HPRG has been reported to bind various ligands and to modulate angiogenesis via the histidine residues of the HPRR. However, the secondary structure prediction of the HPRR reveals that more than 98% is disordered and the structural basis of the hypothesized functions remains unclear. Comparison of the PRR1 of several mammalian species indicates the presence of a conserved binding site that might coordinate the Zn(2+) ion with an amino acid arrangement compatible with the cysteine-containing site that has been identified experimentally for rabbit HPRG. This observation provides a structural basis to the function of HPRG as an intracellular zinc chaperone which has been suggested by the involvement of the protein in the maintenance of the quaternary structure of skeletal muscle AMP deaminase (AMPD). During Anthropoidea evolution, a change of the primary structure of the PRR1 Zn(2+) binding site took place, giving rise to the sequence M-S-C-S/L-S/R-C that resembles the MxCxxC motif characteristic of metal transporters and metallochaperones.
