Project description:It is well established that histone derived antimicrobial peptides (AMPs) have anti-microbial properties in various invertebrate and vertebrate species.To reveal the possible immunoregulatory functions of the engineered S. cerevisiae expressing gcH2A-4(7t) and gcH2A-11(2t) on the grass carp, the intestines from the immunized grass carp were collected at the first immunization for 7 days and used for transcriptome sequencing. The results found that the activation of PRRs-related pathways including TLRs, NLRs and RLRs was revealed in the engineered S. cerevisiae expressing gcH2A-4(7t) and gcH2A-11(2t) on the grass carp intestines."

Project description:Purpose:Salinity is an important environmental factor that affects the physiological activities of fish. The goals of this study are investigating the effect of different saline-alkali stress on grass carp (Ctenopharyngodon idella). Methods: Grass carp individuals, averaging 12 cm in body length, were obtained from Duofu fish farm (Wuhan, China) and cultured at recirculating aquaculture system for 2 weeks before the experiment began. For the challenge, all grass carp were randomly divided into three groups, and then cultured at saline-alkali water with the concentration of 0, 3‰ and 6‰. After 30 days, some grass crap cultured at 3‰ and 6‰ saline-alkali water were injured. At the same time, gill samples of grass carp were collected from 0, 3‰ (grass carp was not injured), 3‰ (grass carp was injured), 6‰ (grass carp was not injured) and 6‰ (grass carp was injured)saline-alkali groups. Total RNA of all samples was isolated using TRIzol® Reagent (Invitrogen) according to the manufacturer's introduction. RNA integrity was assessed using an Agilent 2100 bioanalyzer (Agilent, USA). Samples with RNA integrity numbers (RINs) ≥ 7.5 were subjected to cDNA library construction using TruseqTM RNA sample prep Kit (Illumina). Results:A total of 15 were processed for transcriptome sequencing, generating 94.99Gb Clean Data. At least 5.76Gb clean data were generated for each sample with minimum 91.87% of clean data achieved quality score of Q30. Clean reads of each sample were mapped to specified reference genome. Mapping ratio ranged from 88.59% to 92.84%. The expression of genes was quantified and differentially expressed genes were identified based on their expression.Criteria for differentially expressed genes was set as Fold Change(FC)≥1.5 and Pvalue<0.05. Fold change(FC) refers to the ratio of gene expression in two samples. These DEGs were further processed for functional annotation and enrichment analysis. Conclusions: Our study represents Effects and molecular regulation mechanisms of saline-alkali stress on the healthy grass carp by using RNA-seqtechnology. Our results show that saline-alkali stress will impair the immune system of grass carp.

Project description:In this study, microbial communities from triplicate leach-bed anaerobic bioreactors digesting grass were analysed. Each reactor comprised two microbial fractions, one immobilized on grass (biofilm) and the other in a planktonic state present in the leachate. Microbial communities from the two fractions were systematically investigated for community composition and function. This was carried out using DNA, RNA and protein co-extraction. The microbial structure of each fraction was examined using 16S rRNA deep sequencing, while the active members of the consortia were identified using the same approach on cDNA generated from co-extracted RNA samples. Microbial function was investigated using a metaproteomic workflow combining SDS-PAGE and LC-MS/MS analysis.

Project description:Glycosylation represents a major post-translational modification of proteins that can influence their structure and function.Telesot immunoglobulin M (IgM) is an especially important product of the immune system because it is the main Abs in seum and plays a critical role against defense infection. However, little is known regarding site-specific N-glycan characteristics in teleost IgM , LC-ESI-MS/MS was used to analysis deglycopeptides and glycopeptides of grass carp serum IgM, and MALDI-MS was used to analysis released carbohydrates by PNGaseF diestion of grass carp serum IgM.

Project description:The increased urban pressures are often associated with specialization of microbial communities. Microbial communities being a critical player in the geochemical processes, makes it important to identify key environmental parameters that influence the community structure and its function.In this proect we study the influence of land use type and environmental parameters on the structure and function of microbial communities. The present study was conducted in an urban catchment, where the metal and pollutants levels are under allowable limits. The overall goal of this study is to understand the role of engineered physicochemical environment on the structure and function of microbial communities in urban storm-water canals. Microbial community structure was determined using PhyoChio (G3) Water and sediment samples were collected after a rain event from Sungei Ulu Pandan watershed of >25km2, which has two major land use types: Residential and industrial. Samples were analyzed for physicochemical variables and microbial community structure and composition. Microbial community structure was determined using PhyoChio (G3)

Project description:SERPINA1, a member of the serine protease inhibitor family, plays a role in viral infection and inflammation by regulating the activities of serine and cysteine proteases. To further investigate the antiviral role SERPINA1 played in GCRV (Grass carp Reovirus) infection, a polyclonal antibody of SERPINA1 was prepared, and the protein interacting with SERPINA1 was screened by CoIP/MS in grass carp hepatopancreas tissue. Samples of hepatopancreas tissues from grass carp (n=3) before (healthy) and 8 days after the infection (post-infection) were selected. Grass carp were infected by intraperitoneal injection. The total tissue proteins were extracted according to the manufacturer’s instructions for cell lysate (Beyotime, Shanghai, China). The types and abundance of proteins bound to SERPINA1 before and after the infection were detected and analyzed using CoIP-MS.

Project description:Because antibiotics have been widely used to prevent severe losses due to infectious fishery diseases, the liberal application and overuse of antibiotics has led to the spread and evolution of bacterial resistance, food safety hazards, and environmental issues. The use of some antibiotics, including florfenicol and enrofloxacin, is allowed in aquaculture in China. Accordingly, to better address the concerns and questions associated with the impact of administered enrofloxacin and florfenicol to grass carp, here we investigated the immune response, bacterial diversity, and transcriptome of the intestine of C. idella treated with these oral antibiotics. The aim of this study was to provide an in-depth evaluation of the antibiotic-induced patterns and dynamics of the microbiota grass carp and the potential mechanism involved.
