As a part of our effort to obtain a strong regulatory element for the construction of an autogenic mud loach transgenic vector, we isolated a genomic clone that contains an open reading frame encoding the beta-actin gene, then examined the transcriptional activity of the upstream sequences, including the first intron, in transiently transfected cell lines.(More)
Transgenic mud loaches (Misgurnus mizolepis), in which the entire transgene originated from the same species, have been generated by microinjecting the mud loach growth hormone (mlGH) gene fused to the mud loach beta-actin promoter. Out of 4,100 eggs injected, 7.5% fish derived from the injected eggs showed dramatically accelerated growth, with a maximum of(More)
Protease nexin-1 (PN-1) is a serine protease inhibitor (SERPIN) protein with functional roles in growth, development, patho-physiology and injury. Here, we report our work to clone, analyze the expression profile and characterize the properties of the PN-1 gene in rock bream (Rb), Oplegnathus fasciatus. RbPN-1 encodes a peptide of 397 amino acids (AA) with(More)
The mud loach (Misgurnus mizolepis) growth hormone (GH) gene was cloned and a comparative analysis on its genomic organization was performed. Based on Southern analysis using various kinds of restriction endonucleases, the GH gene proved to exist as a single-copy gene in the mud loach. The complete nucleotide sequences of a 5.1 kb SacI/EcoRI genomic(More)
The CXCR1 and CXCR2 are the prototypical receptors and are the only known receptors for mammalian ELR+ (Glu-Leu-Arg) CXC chemokines, including CXCL8 (interleukin 8). These receptors transduce the ELR+ chemokine signals and operate the downstream signaling pathways in inflammation and innate immunity. In this study, we report the identification and(More)
The p38 kinases are one of the four subgroups of mitogen-activated protein kinase (MAPK) superfamily which are involved in the innate immunity. The p38 subfamily that includes four members namely p38α (MAPK14), p38β (MAPK11), p38γ (MAPK12) and p38δ (MAPK13), regulates the activation of several transcription factors. In this study, a p38β (OfMAPK11) homolog(More)
Interleukin 1β (IL-1β) and interleukin 8 (IL-8) are two major pro-inflammatory cytokines which play a central role in initiation of inflammatory responses against bacterial- and viral-infections. IL-1β is a member of the interleukin 1 family proteins and IL-8 is classified as a CXC-chemokine. In the current study, putative IL-1β and IL-8 counterparts were(More)
Chemokines are small, structurally related chemotactic cytokines characterized by the presence of conserved cysteine residues. In the present study, we identified the cDNA of a CXC chemokine from Oplegnathus fasciatus, designated as OfCXCL12. An open reading frame of 297 bp encoded a 98 amino acid peptide with a putative signal peptide of 23 amino acids.(More)
Cysteine proteases are present in all living organisms and, in animals, function in a vast array of physiological and pathological processes. Cysteine protease inhibitors act upon the cysteine proteases to regulate their activity. The cystatin superfamily of cysteine protease inhibitors has members represented in all living organisms studied to date. Here,(More)
Apoptosis plays a key role in the physiology of multicellular organisms and is regulated by different promoting and inhibitory mechanisms. Cytokine-induced apoptotic inhibitor (CIAPI) was recently identified as a key factor involved in apoptosis inhibition in higher vertebrate lineages. However, most of the CIAPIs of lower vertebrate species are yet to be(More)
