  abstract  = {The silver carp (Hypophthalmichthys molitrix) growth hormone (GH) genewas isolated and sequenced following amplification from genomic DNA by the polymerase chain reaction. The gene spans a region of approx. 2.5 kb nucleotides (nt) and consists of five exons. The sequence predicts a polypeptide of 210 amino acids (aa) including a putative signal peptide of 22 hydrophobic aa residues. The arrangement of exons and introns is identical to the GH genes of common carp, grass carp, and very similar to mammals and birds, but quite different from that for the GH genes of tilapia and salmonids. The silver carp GH gene shares a high homology at the nt and aa Ievels with those of grass carp (95.3\% nt, 99.5\% aa) and of common carp (81\% nt, 95.7\% aa).},

  abstract  = {The promoter of the rainbow trout metallothionein B gene ( tMTb) was isolated from genomic DNA by the polymerase chain reaction (PCR ), fused to the bacterial chloramphenicol acetyltransferase (CAT) genein an expression vector, and functionally analyzed in one human cellline and four fish celllines. This promoter exhibited an extremely low basal expression in all celllines and was zincand cadmium-inducible except in the fish melanoma cell line where the promoter was completely inactive. The metal-induced expression patterns were cellline-specific. In general the fish promoter was more species- and cell type-specific than its human counterpart. In a transient assay it was functional in developing embryos of the medaka ( Oryzias /atipes). These properties make this promoter suitable for inducible, tissue-specific expression of transgenes and for in vivo studies of gene function and regulation.},

  abstract  = {In order to develop all-fish expression vectors for microinjection into fertilized fish eggs, we have prepared the following cunstructs: rainbow trout metallothionein a/b and the gilthead seabream growth hormone cDNA (ptMTa-gbsGHcDNA, ptMTb-gsbGHcDNA), carp ß-actin gilthead seabream GH cDNA (pcAßgsbGHcDNA). The inducible metallothionein promoters a and b were cloned from rainbow trout, and the constitutive promoter ß-actin was isolated from carp. The metallothionein promoters were cloned by using the PCR technique. The tMTa contains 430 bp, while the tMTb contains 260 bp (Hong et al. 1992). These two promoters were introduced to pGEM-3Z containing the GH cDNA of Sparus aurata to form ptMTa-gsbGH and ptMTb-gsbGH, respectively. The carp cytoplasmic ß-actin gene was chosen as a source for isolating strong constitutive regulatory sequences. One of these regulatory sequences in pUC118 was Iigated to GH cDNA of S. aurata to form the pcAß-gsbGHcDNA. Expression of the constructs containing the metallothionein promoters was tested in fish cell culture and was found tobe induced effectively by zinc. The ptMTa gsb-GH cDNA construct was microinjected into fertilized carp eggs, and integration in the genome of carp was detected in the DNA isolated from fins at the age of two months.},
