Project description:<p><strong>BACKGROUND:</strong> The ultra-high density intensive farming model of grass carp (Ctenopharyngodon idellus) may elicit inhibite the growth, decline flesh quality and disease resistance of fish. The quality degradation and excessive fat accumulation in cultured C. idellus have long been attributed to possible alterations in the lipid metabolism of fish muscle tissues as a result of over-nutrition from artificial diets. To investigate the effects of different diets on fish muscle quality, a large-scale metabolomics study was performed on 200 tails of C. idellus. </p><p><strong>FINDINGS:</strong> The experimental fish were divided into four test groups based on sex and diets - female artificial feed (FAF), female grass feed (FGF), male artificial feed (MAF) and male grass feed (MGF). After a 4-month rearing period, the AF group showed significantly higher total mass of muscle fat (P < 0.01), with the FAF group being the highest. Metabolomics profiling based on liquid chromatography-mass spectrometry (LC-MS) revealed distinctive patterns of clustering according to the four groups. Overall, artificial feeding was associated with higher concentrations of docosapentaenoic acid (DPA), dihomo-gamma-linolenic acid (DGLA) and arachidonic acid (ARA); whereas grass-feeding was associated with elevated n-3 unsaturated fatty acids (n-3 UFAs), such as eicosapentaenoic acid (EPA), alpha-linolenic acid (ALA) and gamma-linolenic acid (GLA). Some sex-specific markers, such as docosahexaenoic acid (DHA) was only found in male samples, with higher levels in the MAF group. Metabolic pathway analyses using both targeted (MetaboAnalyst) and untargeted (mummichog) approaches consistently revealed that the arachidonic acid metabolism and steroid hormone biosynthesis pathways are significantly different between AF and GF groups. </p><p><strong>CONCLUSIONS:</strong> Our results suggested that grass is a better source of diet fatty acid and protein when compared to artificial feed, because it could effectively lower triglycerides in serum, reduce fat accumulation and alter lipid compositions in fish muscle by increasing the concentrations of n-3 UFAs, leading to better nutrition and health.</p>

Project description:BackgroundMyxovirus resistance (Mx) proteins are crucial effectors of the innate antiviral response against a wide range of viruses, mediated by the type I interferon (IFN-I) signaling pathway. However, the antiviral activity of Mx proteins is diverse and complicated in different species.Methodology/principal findingsIn the current study, two novel Mx genes (CiMx1 and CiMx3) were identified in grass carp (Ctenopharyngodon idella). CiMx1 and CiMx3 proteins exhibit high sequence identity (92.1%), and low identity with CiMx2 (49.2% and 49.5%, respectively) from the GenBank database. The predicted three-dimensional (3D) structures are distinct among the three isoforms. mRNA instability motifs also display significant differences in the three genes. The spatial and temporal expression profiles of three C. idella Mx genes and the IFN-I gene were investigated by real-time fluorescence quantitative RT-PCR (qRT-PCR) following infection with grass carp reovirus (GCRV) in vivo and in vitro. The results demonstrated that all the four genes were implicated in the anti-GCRV immune response, that mRNA expression of Mx genes might be independent of IFN-I, and that CIK cells are suitable for antiviral studies. By comparing expression patterns following GCRV challenge or poly(I:C) treatment, it was observed that GCRV blocks mRNA expression of the four genes. To determine the functions of Mx genes, three CiMx cDNAs were cloned into expression vectors and utilized for transfection of CIK cells. The protection conferred by each recombinant CiMx protein against GCRV infection was evaluated. Antiviral activity against GCRV was demonstrated by reduced cytopathic effect, lower virus titer and lower levels of expressed viral transcripts. The transcription of IFN-I gene was also monitored.Conclusions/significanceThe results indicate all three Mx genes can suppress replication of grass carp reovirus and over-expression of Mx genes mediate feedback inhibition of the IFN-I gene.
