Viral envelope proteins are always proposed to exert important function during virus infection and replication. Vertebrate iridoviruses are enveloped large DNA virus, which can cause great economic losses in aquaculture and ecological destruction. Although numerous iridovirus envelope proteins have been identified using bioinformatics and proteomic methods,(More)
BACKGROUND Soft-shelled turtle iridovirus (STIV) is the causative agent of severe systemic diseases in cultured soft-shelled turtles (Trionyx sinensis). To our knowledge, the only molecular information available on STIV mainly concerns the highly conserved STIV major capsid protein. The complete sequence of the STIV genome is not yet available. Therefore,(More)
BACKGROUND Orange-spotted grouper (Epinephelus coioides) is an economically important marine fish cultured in China and Southeast Asian countries. The emergence of infectious viral diseases, including iridovirus and betanodavirus, have severely affected food products based on this species, causing heavy economic losses. Limited available information on the(More)
BACKGROUND MicroRNAs (miRNAs) are ubiquitous non-coding RNAs that regulate gene expression at the post-transcriptional level. An increasing number of studies has revealed that viruses can also encode miRNAs, which are proposed to be involved in viral replication and persistence, cell-mediated antiviral immune response, angiogenesis, and cell cycle(More)
Lysozyme acts as an innate immunity molecule against pathogen infection. In this study, a new G-type lysozyme gene with a typical G-type lysozyme domain (designated as Ec-lysG) was cloned and characterized from the orange-spotted grouper, Epinephelus coioides. The full-length Ec-lysG cDNA contains 1419 bp and encodes a 256-residue protein containing a(More)
Golden pompano is a commercially important marine fish that is widely cultured in China, Japan, and Southeast Asian countries but has been seriously threatened by pathogen. A novel cell line (TOGB) derived from the brain of golden pompano Trachinotus ovatus was established and characterized in this study. TOGB cell line showed high virus susceptibility,(More)
The Singapore grouper iridovirus (SGIV), a member of the genus Ranavirus, is a major viral pathogen that has caused heavy economic losses to the grouper aquaculture industry in China and Southeast Asia. No efficient method of controlling SGIV outbreaks is currently available. Systematic evolution of ligands by exponential enrichment (SELEX) is now widely(More)
c-Jun N-terminal kinase (JNK) regulates cellular responses to various extracellular stimuli, environmental stresses, pathogen infections, and apoptotic agents. Here, a JNK1, Ec-JNK1, was identified from orange-spotted grouper, Epinephelus coioides. Ec-JNK1 has been found involving in the immune response to pathogen challenges in vivo, and the infection of(More)
Golden pompano Trachinotus ovatus, a popularly cultured and commercially important marine fish worldwide, has been recognized as a promising candidate for mariculture. However, outbreaks of infectious bacterial or viral diseases and environmental deterioration have led to great economic losses in T. ovatus aquaculture recently. In our research, we(More)
BACKGROUND Soft-shelled turtle iridovirus (STIV) causes severe systemic disease in farmed soft-shelled turtles (Trionyx sinensis). More efficient methods of controlling and detecting STIV infections are urgently needed.  METHODS In this study, we generated eight single-stranded DNA (ssDNA) aptamers against STIV using systematic evolution of ligands by(More)
