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: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.

Project description:Few studies reported for obtaining the grass carp resistant to hemorrhagic disease via gene editing in commercial fish. Here, we demonstrate that the expression and activity of grass carp PI4KB (gcPI4KB) are vital for GCRV-I and GCRV-II replication. Due that obvious cytopathic effect (CPE) in the present available cell lines is only caused by GCRV-I, but GCRV-II is the current popular and fatal strain in grass carp, GCRV-I and GCRV-II are used in cell lines and in grass carp, respectively. The in vitro studies in CIK cells revealed that gcPI4KB interacted with NS80 and VP3 of GCRV-I, and that gcPI4KB was recruited by NS80 for promoting the generation of GCRV VIBs. Since the negative regulatory role of gcPI4KB in GCRV infection was confirmed by in vitro data,we performed gene editing of gcPI4KB in grass carp. We found that PI4KB F0 crispants juvenile grass carp have obvious advantages in promoting growth and in resisting GCRV-II infection. Compared with uninfected WT grass carp, the uninfected PI4KB F0 crispants juvenile grass carp exhibit a higher expression level of many genes involved in growth- and development-related metabolic pathways such as the FoxO signaling pathway and insulin signaling pathway. Compared with WT grass carp without infection, PI4KB F0 crispants juvenile grass carp without infection or WT grass carp infected with GCRV-II, higher expression levels for many genes involved in metabolic diseases and viral infection were observed in the liver from PI4KB F0 crispants juvenile grass carp infected with GCRV-II. Altogether, the present study suggests the mechanism of gcPI4KB in facilitating GCRV replication, the signaling pathways regulated by gcPI4KB, and the possibility to obtain the grass carp resistant to hemorrhagic disease via gene editing of PI4KB.

Project description:Grass carp (Ctenopharyngodon idellus), the world’s largest aquaculture fish species, exhibits superior growth in females compared to males. However, the lengthy sexual maturation period of four to five years poses a significant obstacle to the genetic reproduction and breeding of grass carp. Consequently, classical methods such as gonadogenesis or sex reversal through steroid treatment, employed for breeding all-female grass carp, demand considerable time and effort. In this study, we developed an super-fast breeding strategy for generating all-female grass carp in a total of half a year, using a surrogate production method. We first characterized grass carp female germline stem cells (GSCs) from genetic female juveniles at three months post-fertilization (mpf). The female GSCs with XX chromosomes were then transplanted into germ cell-depleted zebrafish larvae at five days post-fertilization (dpf). The transplanted grass carp XX germ cells underwent rapid spermatogenesis in the zebrafish recipient. At three months after transplantation, all zebrafish recipients had developed into males capable of producing the all-X sperm of the grass carp. By using these sperm to fertilize wildtype grass carp eggs, we successfully produced an all-female grass carp offspring. This groundbreaking achievement highlights the potential of surrogate production in the genetic breeding of valuable fish species, and opens a new avenue for advancing genetic breeding in aquaculture.

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: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.
