Abstract
Fucoidans possess potent anti-inflammatory effects. In the present study, the anti-inflammatory effect of the fucoidan (SFF-PS-F5) isolated from fermented Sargassum fusiforme was evaluated in vitro in RAW 264.7 macrophages and in vivo in zebrafish. The in vitro test results demonstrate that SFF-PS-F5 effectively inhibited nitric oxide (NO) production induced by lipopolysaccharides (LPS) in RAW 264.7 cells. SFF-PS-F5 effectively and concentration-dependently improved the viability of LPS-stimulated RAW 264.7 cells, and reduced the level of prostaglandin E2, interleukin-1 beta, tumor necrosis factor-alpha, and interleukin-6. Further results display that these effects were actioned by suppressing the expression of inducible nitric oxide synthase and cyclooxygenase-2 via regulating the nuclear factor kappa-B signaling pathway. The in vivo test results indicate that SFF-PS-F5 remarkably reduced reactive oxygen species, cell death, and NO levels in LPS-treated zebrafish. These results indicate that SFF-PS-F5 could inhibit both in vitro and in vivo inflammatory responses and suggest it is a functional ingredient in the functional food and cosmetic industries.

Abstract
Development of low-cost and eco-friendly approaches to fight bacterial pathogens is especially needed in aquaculture. We previously showed that exogenous malate reprograms zebrafish’s metabolome to potentiate zebrafish survival against Vibrio alginolyticus infection. However, the underlying mechanism is unknown. Here, we use GC-MS based metabolomics to identify the malate-triggered metabolic shift. An activated TCA cycle and elevated taurine are identified as the key metabolic pathways and the most crucial biomarker of the reprogrammed metabolome, respectively. Taurine elevation is attributed to the activated TCA cycle, which is further supported by the increased expression of genes in the metabolic pathway of taurine biosynthesis from the isocitrate of the TCA cycle to taurine. Exogenous taurine increases the survival of zebrafish against V. alginolyticus infection as malate did. Moreover, exogenous taurine and malate regulate the expression of innate immunity genes and promote the generation of reactive oxygen species and nitrogen oxide in a similar way. The two metabolites can alleviate the excessive immune response to bacterial challenge, which protects fish from bacterial infection. These results indicate that malate enhances the survival of zebrafish to V. alginolyticus infection via taurine. Thus, our study highlights a metabolic approach to enhance a host’s ability to fight bacterial infection.

Abstract
Inflammation, especially chronic inflammation, has been found to be closely related to the pathology of many diseases and the discovery of bioactive natural products to inhibit NO production is one of strategies to treat inflammation. In our continuous search for bioactive natural substances as potential anti-inflammatory agents, five new compounds (1-5) were extracted and purified from Patrinia heterophylla. The NMR and MS data analysis, along with electronic circular dichroism (ECD) calculations, led to the identification of these isolates, which were new iridoids. Using cell and zebrafish models, the in vitro and in vivo anti-inflammatory effects were conducted to evaluate the potency of anti-inflammation of these compounds. The preliminary mechanism was explored using molecular docking and Western blotting experiments.

Abstract
A fucoidan (LJSF4) purified from Saccharina japonica was found to show a strong anti-inflammatory effect via activity assay in lipopolysaccharide (LPS) induced RAW 264.7 macrophage cells and zebrafish. Chemical and structural analysis indicated that LJSF4 with a sulfate content of 30.72% was composed of fucose, galactose, rhamnose, xylose and mannose with molar ratio percentages of 79.49%, 16.76%, 0.82%, 1.08% and 1.84%. NMR spectroscopy showed that LJSF4 is a polysaccharide with a backbone of alternating 1 → 3 linked α-l-fucopyranosyl and →4-α-l-fucopyranosyl with sulfate groups mainly at C-4 and partially at C-2 positions. Moreover, it also contained branches in the form of β-d-Galp-(1 → 4) units. The results of anti-inflammatory effect in vitro demonstrated that LJSF4 decreased the production of nitric oxide (NO) and cytokines, including TNF-α, IL-1β and IL-6. The mechanism revealed to be associated with the down-regulated expression of signal pathways including MAPK and NF-κB. By in vivo assay, LJSF4 showed a significantly protective effect by reducing the cell death rate, and the production of NO and ROS on LPS exposed zebrafish. Our results indicated that LJSF4 has the potential to be developed as an anti-inflammatory agent applied in functional food and cosmetic industries.

Abstract
BACKGROUND Reactive oxygen species (ROS) produce different lesions in DNA by ROS-induced DNA damage. Detection and quantification of 8-oxo-7,8-dihydroguanine (8-oxoG) within cells are important for study. Human ribosomal protein S3 (hRpS3) has a high binding affinity to 8-oxoG. In this study, we developed an imaging probe to detect 8-oxoG using a specific peptide from hRpS3. Transactivator (TAT) proteins are known to have cell-penetrating properties. Therefore, we developed a TAT-S3 probe by attaching a TAT peptide to our imaging probe. RESULTS A DNA binding assay was conducted to confirm that our probe bound to 8-oxoG and apurinic/apyrimidinic (AP) sites. We confirmed that the TAT-S3 probe localized in the mitochondria, without permeabilization, and fluoresced in H2O2-treated HeLa cells and zebrafish embryos. Treatment with Mitoquinone (MitoQ), a mitochondria-targeted antioxidant, reduced TAT-S3 probe fluorescence. Additionally, treatment with O8, an inhibitor of OGG1, increased probe fluorescence. A competition assay was conducted with an aldehyde reaction probe (ARP) and methoxyamine (MX) to confirm binding of TAT-S3 to the AP sites. The TAT-S3 probe showed competitive binding to AP sites with ARP and MX. CONCLUSIONS These results revealed that the TAT-S3 probe successfully detected the presence of 8-oxoG and AP sites in damaged cells. The TAT-S3 probe may have applications for the detection of diseases caused by reactive oxygen species.

Abstract
The dried vine stems of Spatholobus suberectus are commonly used in traditional Chinese medicine for treating gynecological and cardiovascular diseases. In this study, five new compounds named spasuberol A (2), homovanillyl-4-oxo-nonanoate (5), spasuberol C (6), spasuberoside A (14), and spasuberoside B (15), together with ten known compounds (1, 3, 4, 7–13), were isolated from the dried vine stems of S. suberectus. Their chemical structures were analyzed using spectroscopic assays. This is the first study interpreting the detailed structural information of 4. The anti-inflammatory activity of these compounds was evaluated by reducing nitric oxide overproduction in RAW264.7 macrophages stimulated by lipopolysaccharide. Compounds 1 and 8–10 showed strong inhibitory activity with half maximal inhibitory concentration (IC50) values of 5.69, 16.34, 16.87, and 6.78 μM, respectively, exhibiting higher activity than the positive drug l-N6-(1-iminoethyl)-lysine (l-NIL) with an IC50 value of 19.08 μM. The IC50 values of inhibitory activity of compounds 2 and 4–6 were 46.26, 40.05, 45.87, and 28.29 μM respectively, which were lower than l-NIL, but better than that of positive drug indomethacin with an IC50 value of 55.44 μM. Quantitative real-time polymerase chain reaction analysis revealed that assayed compounds with good anti-inflammatory activity, such as 1, 6, 9, and 10 at different concentrations, can reduce the messenger RNA (mRNA) expression of some pro-inflammatory cytokines such as tumor necrosis factor α (TNF-α), nitric oxide synthase (iNOS), and cyclooxygenase 2 (COX-2). The anti-inflammatory activity and the possible mechanism of the compounds mentioned in this paper were studied preliminarily.

Abstract
In this study, we confirmed the anti-inflammatory effect of Apo-9-fucoxanthinone (AF) in in vitro RAW 264.7 cells and in vivo zebrafish model. In lipopolysaccharide (LPS)-stimulated zebrafish, AF significantly decreased the production of reactive oxygen species (ROS), nitric oxide (NO) and cell death. In addition, the mRNA expression of inducible nitric oxide synthase (iNOS), suppressed cyclooxygenase-2 (COX-2) and an inflammatory cytokines; IL-1β, TNF-α were shown reduction. And AF significantly inhibited NO production and expression of iNOS in LPS-stimulated RAW 264.7 cells. Further, AF suppressed COX-2, prostaglandin E2 (PGE2), and pro-inflammatory cytokines such as interleukin-6 (IL-6), IL-1β, and tumor necrosis factor-α (TNF-α) at 25, 50 and 100 μg/mL, respectively. Further mechanistic studies showed that AF suppressed the nuclear factor-kB (NF-kB) pathway and phosphorylation of mitogen-activated protein kinase (MAPK) pathway molecules such as extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK). According to the results, AF can be used and applied as a useful anti-inflammatory agent of nutraceutical or pharmaceutical.

Abstract
Mori folium, the leaf of Morus alba L. (Moraceae), has been traditionally used for various medicinal purposes from ancient times to the present. In this study, we examined the effects of water extract of Mori folium (WEMF) on the production of inflammatory mediators, such as nitric oxide (NO) and prostaglandin E2 (PGE2), and reactive oxygen species (ROS) in lipopolysaccharide (LPS)-stimulated murine RAW 264.7 macrophages. Our data indicated that WEMF significantly suppressed the secretion of NO and PGE2 in RAW 264.7 macrophages without any significant cytotoxicity. The protective effects were accompanied by a marked reduction in their regulatory gene expression at the transcription level. WEMF attenuated LPS-induced intracellular ROS production in RAW 264.7 macrophages. It inhibited the nuclear translocation of the nuclear factor-kappa B p65 subunit and the activation of mitogen-activated protein kinases in LPS-treated RAW 264.7 macrophages. Furthermore, WEMF reduced LPS-induced NO production and ROS accumulation in zebrafish. Although more efforts are needed to fully understand the critical role of WEMF in the inhibition of inflammation, the findings of the present study may provide insights into the approaches for Mori folium as a potential therapeutic agent for inflammatory and antioxidant disorders.

Abstract
Spermidine is a naturally occurring polyamine compound that has recently emerged with anti-aging properties and suppresses inflammation and oxidation. However, its mechanisms of action on anti-inflammatory and antioxidant effects have not been fully elucidated. In this study, the potential of spermidine for reducing pro-inflammatory and oxidative effects in lipopolysaccharide (LPS)-stimulated macrophages and zebrafish was explored. Our data indicate that spermidine significantly inhibited the production of pro-inflammatory mediators such as nitric oxide (NO) and prostaglandin E2 (PGE2), and cytokines including tumor necrosis factor-α and interleukin-1β in RAW 264.7 macrophages without any significant cytotoxicity. The protective effects of spermidine accompanied by a marked suppression in their regulatory gene expression at the transcription levels. Spermidine also attenuated the nuclear translocation of NF-κB p65 subunit and reduced LPS-induced intracellular accumulation of reactive oxygen species (ROS) in RAW 264.7 macrophages. Moreover, spermidine prevented the LPS-induced NO production and ROS accumulation in zebrafish larvae and was found to be associated with a diminished recruitment of neutrophils and macrophages. Although more work is needed to fully understand the critical role of spermidine on the inhibition of inflammation-associated migration of immune cells, our findings clearly demonstrate that spermidine may be a potential therapeutic intervention for the treatment of inflammatory and oxidative disorders.

The hypothesis tested in this study was that Cu pre-acclimation would mitigate high Cu induced immunotoxic effects in large yellow croaker Pseudosciaena crocea. To the end, fish were pre-acclimation to 0 and 84μg CuL-1 for 48h and then exposed to 0 and 420μg CuL-1 for another 48h. Survival rate, Cu content, ROS, NO, activities and mRNA levels of inflammatory genes (iNOS and COX-2), and gene expressions of transcription factor NF-κB and its inhibitor IκBα were determined in spleen and head-kidney of large yellow croaker. Cu pre-acclimation significantly reduced mortality of fish exposed to 420μg CuL-1. Cu pre-acclimation triggered the up-regulation of both enzyme activities and express levels of iNOS and COX-2 in spleen under 420μg CuL-1 exposure, resulting in remarkable reduction of Cu content and ROS in this tissue. Contrast to spleen, iNOS activity remained unchanged but the mRNA level of iNOS increased, and the mRNA level of COX-2 remained constant though COX-2 activity enhanced in head-kidney, suggesting iNOS and COX-2 may be modulated by Cu at a post-transcriptional level. In this process, NF-κB/IκBα signaling molecules may play a vital role in the transcriptional activation of inflammatory genes in both spleen and head-kidney. In conclusion, low Cu pre-acclimation alleviated high Cu induced immunotoxicity in spleen and head-kidney of large yellow croaker by enhancing the activities and mRNA levels of inflammatory genes.

The roles of NF-κB and ROS in regulation of pro-inflammatory mediators of inflammation induction in LPS-stimulated zebrafish embryos. FISH & SHELLFISH IMMUNOLOGY 2017; 68:525-529. [PMID: 28743626 DOI: 10.1016/j.fsi.2017.07.041] [Citation(s) in RCA: 75] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/14/2017] [Revised: 07/17/2017] [Accepted: 07/21/2017] [Indexed: 06/07/2023]
Abstract
In this study, the roles of reactive oxygen species (ROS) and NF-κB on inflammation induction in lipopolysaccharide (LPS)-stimulated zebrafish embryos were evaluated using N-acetyl-l-cysteine (NAC) and pyrrolidine dithiocarbamate (PDTC), specific inhibitors of ROS and NF-κB, respectively. LPS-stimulated zebrafish embryos showed increasing production of NO and ROS and expression of iNOS and COX-2 protein, compared to a control group without LPS. However, NAC significantly inhibited production of NO and ROS and markedly suppressed expression of iNOS and COX-2 protein in LPS-stimulated zebrafish embryos. The mRNA expressions of NF-κB such as p65NF-κB and IκB-A were significantly increased after LPS stimulation, whereas PDTC attenuated mRNA expression of NF-κB. PDTC also inhibited production of NO and reduced expression of iNOS and COX-2 protein in LPS-stimulated zebrafish embryos. Taken together, these results indicated that LPS increases pro-inflammatory mediators in zebrafish embryos through ROS and NF-κB regulation.
