A subtracted cDNA library from lipopolysaccharide (LPS)-stimulated Epinephelus awoara spleen was constructed using the suppression subtractive hybridization (SSH). Random clones (209) were selected and sequenced. After assembling, 36 contigs and 56 singlets (accession numbers: EB410743-EB410834) were finally obtained, some of which were immune-related(More)
Rel\NF-kappaB signal transduction pathway is evolutionarily conserved and involved in numerous biological processes. We report here, for the first time that a homologue of Rel\NF-kappaB transcription factor, Ab-Rel, was identified and functionally characterized in a gastropod abalone, H. diversicolor supertexta. The full-length Ab-Rel cDNA consists of 1943(More)
Rickettsia-like organism (RLO) caused mass mortality of oysters, but little is known about the protective immune response to this microorganism. The present study was undertaken to identify a gene, ompR, encoding an outer membrane protein of rickettsia-like organism from oyster Crassostrea ariakensis. The role of this protein in promoting immune responses(More)
The BMP1/TLD-like proteinases are pleiotropic, astacin-like metalloproteinases. They play central roles in regulating the formation of the extracellular matrix (ECM) and signaling through various TGFbeta-like proteins in morphogenetic and homeostatic events. Here we describe the cloning, structural characterization and expression of Tolloid-like gene in the(More)
Moribund specimens of the oyster, Crassostrea ariakensis Gould, aged 2-3 years were collected from Hailing Bay in Yangxi County of Guangdong Province from February to May and November to December in the years 2001, 2002, and 2003. A massive infection by an obligate intracellular prokaryote, specifically a rickettsia-like organism (RLO), was found. Here we(More)
Ran protein is a central molecular in several key nuclear functions, including nucleocytoplasmic transport, cell-cycle progression and nuclear envelope assembly. In this study, we have isolated and characterized a Ran homologue from a gastropod abalone which we named ab-Ran. The full-length cDNA consists of 1239 bp with an ORF encoding a 220 amino acid(More)
A SMARTer™ cDNA library of hemocyte from Rickettsia-like organism (RLO) challenged oyster, Crassostrea ariakensis Gould was constructed. Random clones (400) were selected and single-pass sequenced, resulted in 200 unique sequences containing 96 known genes and 104 unknown genes. The 96 known genes were categorized into 11 groups based on their biological(More)
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL/Apo2L) is one of the tumor necrosis factor (TNF) superfamily members, participating in many biological processes including apoptosis and immune responses. In present study, a novel human soluble TRAIL (sTRAIL) homolog, CasTRAIL was identified from the oyster, Crassostrea ariakensis. CasTRAIL has(More)
The beta-thymosins are a family of highly conserved small peptides with multiple functions. In this study, we isolated the full-length cDNA of a beta-thymosin homologue from a gastropod abalone Haliotis diversicolor supertexta which we named ab-TMSB. The full-length cDNA of ab-TMSB consists of 499 bp with an ORF encoding a 43 amino acids protein. The(More)
The cAMP response element-binding protein (CREB) is a transcription factor that plays important roles in cellular growth, proliferation and survival. Here, we report that a homologue of CREB transcription factor, Ca-CREB, was identified and functionally characterized in oyster, Crassostrea ariakensis. The full-length cDNA consists of 1397bp with an ORF(More)
