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 β-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)
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 β-actin gene, then examined the transcriptional activity of the upstream sequences, including the first intron, in transiently transfected cell lines. It(More)
The shortnose sturgeon Acipenser brevirostrum was revealed to have a larger number of chromosomes than previously reported for other sturgeon species. Its chromosome number ranged from 362 to 372 (of ten specimens examined), showing intraindividual variation. The karyotype of metaphase with the highest chromosome number (372) consisted of 89 pairs 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 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)
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)
Seven new microsatellite markers were developed for the Pacific abalone (Haliotis discus hannai, Haliotidae), and allelic variability was compared between a wild population and a hatchery population in Yeosu, Korea. All loci amplified readily and demonstrated allelic variability, with the number of alleles ranging from 6 to 15 in the wild population 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)
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)
