BACKGROUND Turbot reddish body iridovirus (TRBIV) causes serious systemic diseases with high mortality in the cultured turbot, Scophthalmus maximus. We here sequenced and analyzed the complete genome of TRBIV, which was identified in Shandong province, China. RESULTS The genome of TRBIV is a linear double-stranded DNA of 110,104 base pairs, comprising 55%(More)
Tiger frog virus (TFV), in the genus Ranavirus of the family Iridoviridae, causes high mortality of cultured tiger frog tadpoles in China. To explore the cellular entry mechanism of TFV, HepG2 cells were treated with drugs that inhibit the main endocytic pathways. We observed that TFV entry was inhibited by NH(4)Cl, chloroquine, and bafilomycin, which can(More)
Infectious spleen and kidney necrosis virus (ISKNV) is the type species of the genus Megalocytivirus from the family Iridoviridae. Megalocytiviruses have been implicated in more than 50 fish species infections and currently threaten the aquaculture industry, causing great economic losses in China, Japan, and Southeast Asia. However, the cellular entry(More)
Caveolae, the major source of caveolin-1 protein, are specialized invaginated microdomains of the plasma membrane that act as organizing centers for signaling molecules in the immune system. In the present study, we report the cloning and characterization of caveolin-1 (mCav-1) from mandarin fish (Siniperca chuatsi) and study on the roles of mCav-1 in the(More)
Infectious spleen and kidney necrosis virus (ISKNV) is the type species of the genus Megalocytivirus from the family Iridoviridae. ISKNV is one of the major agents that cause mortality and economic losses to the freshwater fish culture industry in Asian countries, particularly for mandarin fish (Siniperca chuatsi). In the present study, we report that the(More)
We sequenced and analyzed the complete genome of a fish nervous necrosis virus isolated from diseased sea perch (Lateolabrax japonicus) in Guangdong Province, China. The virus genome contains RNA1 (3,103 bp) and RNA2 (1,433 bp). Phylogenetic analysis shows that the virus belongs to the redspotted grouper nervous necrosis virus genotype of betanodavirus.
MicroRNAs (miRNAs) participate in almost all biological processes. Plenty of evidences show that some testis- or spermatozoa-specific miRNAs play crucial roles in the process of gonad and germ cell development. In this study, the spermatozoa miRNA profiles were investigated through a combination of illumina deep sequencing and bioinformatics analysis in(More)
A protein kinase containing Z-DNA binding domains (PKZ), which resembles protein kinase R (PKR) in domain organization, was recently discovered to be a member of the eIF2α kinase family in fish. PKR has roles in antiviral immunity through inhibiting protein synthesis and activating NF-κB; therefore, it is thought that PKZ may have a similar role in fish(More)
Infectious spleen and kidney necrosis virus (ISKNV) belongs to the genus Megalocytivirus from the family Iridoviridae. Megalocytivirus causes severe economic losses to tropical freshwater and marine culture industry in Asian countries and is devastating to the mandarin fish farm industry in China particularly. We investigated the involvement of(More)
