Abstract
Mammalia cysteamine (2-aminoethanethiol) dioxygenase (ADO) controls the stability of the regulator of G protein signaling 4 (RGS4) through the Cys branch of the Arg/N-degron pathway, thereby affecting the response of the body to hypoxia. However, the oxygen-sensing function of ADO remains unknown in teleost fish. Mandarin fish (Siniperca chuatsi) is one of the most important freshwater economic fishes in China. As the scale of the rearing density continues to increase, hypoxia has become an important factor threatening the growth of mandarin fish. Herein, the molecular characterization, the oxygen-sensing enzyme function, and the role in virus infection of ADO from mandarin fish (scADO) were explored. Bioinformation analysis results showed that scADO had all the molecular foundations for achieving thiol dioxygenase function: three histidine residues coordinated with Fe(II), PCO/ADO domain, and a "jelly roll" β-barrel structure. The expression pattern analysis showed that scAdo was highly expressed in the immune-related tissues, liver, and kidneys and responded to hypoxia on the expression level. Protein degradation experiment results revealed that scADO could lead to the degradation of RGS4 protein through the Cys branch of the Arg/N-degron pathway. Furthermore, the expression levels of scADO responded to fish virus infection. scADO could significantly promote the replication of Siniperca chuatsi rhabdovirus, and this was associated with its thiol dioxygenase activity. These findings not only demonstrate scADO as an oxygen-sensing protein in teleost fish, but are also of considerable importance for clarifying the contribution of the mechanism of hypoxia to the outbreaks of fish viruses.

Abstract
Siniperca chuatsi rhabdovirus (SCRV) is an important pathogen that infects mandarin fish. A reverse genetics system is an important technical platform for virus research. In this study, the minigenome in which the enhanced green fluorescent protein gene is flanked by the viral genomic ends of SCRV and transcribed using a T7 promoter-terminator cassette was constructed. Co-transfection of the minigenome construct with SCRV-supporting plasmids of N, P, and L in BSRT7 cells resulted in the expression of the reporter gene. Transcription of a positive-strand RNA copy from cDNA of the SCRV genome along with the viral N, P, and L proteins resulted in the recovery of infectious SCRV in cells. Viral titre up to 108 PFU/ml was achieved. Recombinant SCRV was verified by the detection of a unique restriction site engineered into the SCRV genome. The phenotypes of the recombinant SCRV and the parental virus were evaluated by plaque size, replication kinetics in vitro, and pathogenicity in vivo. The recovered SCRV from cDNA showed similar phenotypes compared to the parental virus. The established reverse genetics system is of great significance and value for the functional genome study of SCRV and for laying a foundation for the development of the viral vector and SCRV vaccine.

Abstract
The tripartite motif (TRIM) proteins play critical roles in viral infection by modulating innate immunity. However, the molecular and antiviral activity of TRIM59 in mandrain fish is not fully understood. In present study, we cloned and sequenced the TRIM59 core sequence and explored its characteristics in Mandarin fish. The Siniperca chuatsi TRIM59 (scTRIM59) showed relatively high expression in immune-related organs. scTRIM59 expression was significantly down-regulated post ISKNV infection in vivo and vitro, but up-regulated at the early stages of SCRV infection in CPB cells. The overexpression of scTRIM59 inhibited ISKNV and SCRV infection, but decreased the expression of IRF3/IRF7-mediated signal genes. However, knockdown of scTRIM59 promoted the ISKNV and SCRV infection, but increased the expression of IRF3/IRF7-mediated signal genes. Those results indicated that scTRIM59 negatively regulated ISKNV, SCRV infection and IRF3/IRF7-mediated signal genes. This study provided new ideas about the function of scTRIM59.

Abstract
In this study, we established and characterized a continuous cell line from the spinal cord tissue of mandarin fish, Siniperca chuatsi and assessed its susceptibility to infectious spleen and kidney necrosis virus (ISKNV), Siniperca chuatsi ranavirus (SCRaV) and Siniperca chuatsi rhabdovirus (SCRV). The cell line, named SCC, has been successively cultured up to 40 passages. The optimal growing conditions of SCC cells were in Leibovitz's L-15 medium supplemented with 20% foetal bovine serum (FBS) at 28°C. Karyotype analysis demonstrated 48 normal diploid chromosomes in the cells. The identity of S. chuatsi origin of SCC cells was confirmed by partial sequencing of the 16S rRNA and cytochrome oxidase I (COI) genes. Infection susceptibility assessment showed that ISKNV, SCRIV and SCRV and can be stably produced and transmitted in SCC cells, and the replication efficiency of ISKNV, SCRaV and SCRV ranged from 107.4 to 109.6 TCID50 /ml. In addition, transmission electron microscopy analysis of ISKNV, SCRAV and SCRV infected SCC cells showed numerous viral particles. In conclusion, the newly established SCC cells provide an important tool for isolation and production of viruses, as well as for molecular and cell biology studies.

Abstract
c-Myc is a transcription factor and master regulator of cellular metabolism, and plays a critical role in virus replication by regulating glutamine metabolism. In this study, the open-reading frame (ORF) of c-Myc, designated as Sc-c-Myc, was cloned and sequenced. Multiple alignment of the amino acid sequence showed that the conserved domain of Sc-c-Myc, including the helix-loop-helix-zipper (bHLHzip) domain and Myc N-terminal region, shared high identities with other homologues from different species. Sc-c-Myc mRNA was widely expressed in the examined tissues of mandarin fish, and the higher mRNA levels was expressed in hind kidney. Moreover, mRNA and protein level of Sc-c-Myc was significantly increased in the Chinese perch brain (CPB) cells and spleen of mandarin fish post infection with infectious spleen and kidney necrosis virus (ISKNV) and Siniperca chuatsi rhabdovirus (SCRV). Sc-c-Myc overexpression promoted ISKNV and SCRV replication, on the contrary, knocking down Sc-c-Myc restrained ISKNV and SCRV replication. These results indicated that Sc-c-Myc involved in ISKNV and SCRV replication and proliferation, providing a potential target for the development of new therapic strategy against ISKNV and SCRV.

Abstract
Autophagy is an important mechanism for organisms to eliminate viruses and other intracellular pathogens. Siniperca chuatsi rhabdovirus (SCRV) is an agent that has caused devastating losses in Chinese perch (Siniperca chuatsi) industry. But the role of autophagy in Siniperca chuatsi rhabdovirus (SCRV) infection is not clearly understood. In this study, we identified that SCRV infection triggered autophagy in CPB cells, which was demonstrated by the appearance of the membrane vesicles, GFP-LC3 punctuate pattern, conversion of LC3-I to LC3-II, and the co-localization of autophagosomes and lysosomes. The changes of autophagy flux in SCRV infection indicated that autophagy was inhibited at the early stage of SCRV infection, but was promoted at the late stage. UV-inactivated SCRV can induce autophagy, suggesting that SCRV replication is not essential for the induction of autophagy. Furthermore, we found inducing autophagy with Rapa inhibited SCRV proliferation, but inhibiting autophagy with 3-MA or CQ increased SCRV production in CPB cells. Then we assessed the effects of PI3K/Akt-mTOR signaling pathway on SCRV induced autophagy. We found that SCRV infection activated PI3K/AKT signaling pathway at 4 hpi, but inhibited it at 8 hpi. SCRV-N mRNA and protein level were decreased by inhibiting PI3K with LY294002, but increased by activating PI3K with 740Y-P. Those results indicated that SCRV infection induced autophagy via the PI3K/Akt-mTOR signal pathway, which will provide new insights into SCRV pathogenesis and antiviral treatment strategies.

Abstract
Epidermal growth factor receptor (EGFR) is a tyrosine kinase protein and plays a critical role in virus infection by modulating innate immunity. In this study, we cloned and sequenced the EGFR coding sequence of mandarin fish, designed as scEGFR, and explored its characteristics. scEGFR mRNA was widely expressed in the tested tissues of mandarin fish, and the higher mRNA levels were expressed in kidney and spleen. scEGFR expression was up-regulated in spleen and CPB cells at early stage of ISKNV and SCRV infection. Gefitinib (EGFR inhibitor) inhibited ISKNV and SCRV replication, and increased the expression of the interferon-stimulated genes (ISG). However the EGF (EGFR activator) promoted ISKNV and SCRV replication, and decreased the interferon-stimulated genes. Those results indicated that scEGFR and its signaling involved in ISKNV and SCRV infection, and EGFR activation negatively regulated the interferon response, providing a potential target for the development of new therapic strategy against ISKNV and SCRV.

Abstract
In spite of the quite common co-infections of viruses in the cultured fish, most of the previous studies have just simply focused on the infection of a single pathogen. In this report, we observed that about 13% of cultured Chinese perch have been co-infected by infectious spleen and kidney necrosis virus (ISKNV) and Siniperca chuatsi rhabdovirus (SCRV). Furthermore, Chinese perch could co-infected by ISKNV and SCRV by intraperitoneally injection with the two viruses. Interestingly, we revealed that the two viruses could even co-infect a single cell of Chinese perch in vivo and a single Chinese perch brain cells (CPB) cell in vitro. The dynamic co-infected viruses loads in the different tissues of Chinese perch showed dependent. When CPB cells were infected with the same 10 MOI of SCRV and ISKNV, the replication of SCRV overwhelmed the replication of ISKNV. When the MOI of ISKNV (10 MOI) was 10,000 times of MOI of SCRV (0.001 MOI), the dynamic virus loads of the two viruses in CPB cells indicated that co-infections could synergistically stimulate both viruses replication at the late time points but not at early time points. The co-infections of ISKNV and SCRV in the cultured Chinese perch will shed a new light on the prevention of the viral diseases of Chinese perch. The development of multivalent vaccine which could be effective for preventing against the co-infections of the viruses is highly needed.

Abstract
In recent years, the tumor suppressor protein p53, which is crucial for cellular defense against tumor development, has also been implicated in host antiviral defense. In the present study, a 1555 bp full-length cDNA of p53 from mandarin fish (Siniperca chuatsi) (Sc-p53) was cloned and characterized. Quantitative real-time PCR assays revealed that Sc-p53 was expressed in all tissues examined, and it was most abundant in the gill and kidney. Recombinant Sc-p53 fused with a His·Tag was expressed in Escherichia coli BL21 (DE3) cells and a rabbit polyclonal antibody was raised against recombinant Sc-p53. In addition, the regulation of Sc-p53 gene expression after experimental viral infection was determined and characterized. The mRNA and protein expression of Sc-p53 were significantly up-regulated in the Chinese perch brain (CPB) cell line and mandarin fish after infection with infectious kidney and spleen necrosis virus (ISKNV). The results showed a biphasic expression pattern of Sc-p53 protein in CPB. However, a different expression pattern of Sc-p53 in response to S. chuatsi rhabdovirus (SCRV) infection was found. The mRNA expression of Sc-p53 was significantly up-regulated in CPB at 6 h and spleen of mandarin fish at 24 h post-infection. The protein expression of Sc-p53 was significantly up-regulated in CPB at 1 h, remained elevated at 4 h, and then decreased to control level at 8 h post-infection by SCRV. All of these data suggested that Sc-p53 plays a critical role in immune defense and antiviral responses.

Abstract
Hepcidins are small cysteine-rich antimicrobial peptides that play an important role in host immunity against pathogenic organisms. In this study, two hepcidins, SA-hepcidin1 and SA-hepcidin2, were cloned from spotted scat (Scatophagus argus), and the tissue distributions of SA-hepcidins were determined. In addition, mature SA-hepcidin peptides were synthesized to allow evaluation of their antimicrobial and antiviral functions in vitro. SA-hepcidin1 belongs to the HAMP1 class and is widely expressed in all tested tissues from spotted scat, whereas SA-hepcidin2 belongs to the HAMP2 class and present only in the liver. The synthetic SA-hepcidins had similar levels of antibacterial activity against Gram-positive and Gram-negative bacteria; however, the antibacterial activity of SA-hepcidin1 was stronger than that of SA-hepcidin2. The antiviral activities of the synthetic SA-hepcidins were assessed against Siniperca chuatsi rhabdovirus (SCRV) and largemouth bass Micropterus salmoides reovirus (MsReV) in epithelioma papulosum cyprini (EPC) and grass carp fin (GCF) cells. SA-hepcidin2 had antiviral activity, but SA-hepcidin1 did not. The results of this study suggest that SA-hepcidins are important multifunctional proteins in the spotted scat immune system that are involved in resistance to various pathogens.
