Abstract
Porcine growth hormone (pGH) has many important biological functions and roles, and the biological activity of pGH is closely related with its cell behavior and characteristics. However, so far, the behavior of pGH in swine testicular cell remains unclear. For this, in the current work, the swine testicular cell line (ST) was used as an in vitro model, and CLSM (Confocal laser scanning microscope), IFA (Indirect immunofluorescence assay), FCM (Flow cytometry) and WB (Western-blotting) were used to explore the pGH's cell behivior and function, and the results showed that pGH and GHR could internalize into ST cell and transported to the nucleus. Furthermore, we studied the internalization kinetics of pGH and GHR on ST cell, and found that pGH and GHR internalizes into ST cell in a time-dependent manner. More importantly, we also investigated the potential molecular functions of pGH-GHR after it entered into the cell nuclei. The results indicated that nuclear-localized GHR could participate in cell proliferation by regulating the signal intensity of STAT5. In summary, our current research shows that the nuclear-localized pGH-GHR participates in the cell proliferation of ST cell, which lays a solid foundation for further research on the regulatory effect of pGH on testicular tissue.

Abstract
This study aimed to investigate the effects of polymorphisms in growth hormone 1 (GH1) gene on the growth traits in Chinese indigenous yak. Using the polymerase chain reaction-restriction fragment length polymorphism (PCR-PFLP) approach, one novel single-nucleotide polymorphism (SNP), termed as g.1721G>A, was identified in the exon 4 of GH1 gene in 423 individuals of yak population. Based on the chi-square (χ2) test, the frequencies of g.1721G>A alleles agreed with Hardy-Weinberg equilibrium (HWE) (P < 0.05). A significant association was observed between this SNP and several growth traits (P < 0.01 or P < 0.05), in which the genotype GG exhibited the best values. The present study suggested that the identified SNP was a useful genetic marker for the improvement of growth traits in Chinese indigenous yak.

Abstract
Recombinant technologies have made possible the production of a broad catalogue of proteins of interest, including those used for animal production. The most widely studied proteins for the animal sector are those with an important role in reproduction, feed efficiency, and health. Nowadays, mammalian cells and fungi are the preferred choice for recombinant production of hormones for reproductive purposes and fibrolytic enzymes to enhance animal performance, respectively. However, the development of low-cost products is a priority, particularly in livestock. The study of cell factories such as yeast and bacteria has notably increased in the last decades to make the new developed reproductive hormones and fibrolytic enzymes a real alternative to the marketed ones. Important efforts have also been invested to developing new recombinant strategies for prevention and therapy, including passive immunization and modulation of the immune system. This offers the possibility to reduce the use of antibiotics by controlling physiological processes and improve the efficacy of preventing infections. Thus, nowadays different recombinant fibrolytic enzymes, hormones, and therapeutic molecules with optimized properties have been successfully produced through cost-effective processes using microbial cell factories. However, despite the important achievements for reducing protein production expenses, alternative strategies to further reduce these costs are still required. In this context, it is necessary to make a giant leap towards the use of novel strategies, such as nanotechnology, that combined with recombinant technology would make recombinant molecules affordable for animal industry.

Abstract
CONTEXT In previous investigations, we have demonstrated the mutations in the signal peptide of porcine GH gene were associated with the body size. METHODS In this study, the fusion gene expression vectors which consisted of eight signal peptide mutants of GH gene and EGFP gene were constructed according to three missense mutations (p.Val9Ala, p.Gln22Arg and p.Asp25Gly), and they were transfected into the GH3 cell line. RESULTS The inhibition levels of EGFP gene transcriptions with different signal peptide mutants were significantly different. Typically, the allelic variants carrying Val in codon nine showed higher protein synthesis (P < 0.05), and the allelic variants carrying neutral Gln in codon 22 and Gly in codon 25 showed higher secretion proportion (P < 0.05) compared with the other groups as assessed by western blotting. In silico RNA folding prediction indicated that the mutations gave rise to different RNA secondary structures, suggesting that they might affect translation and protein synthesis. CONCLUSION We conclude that the missense mutations within the signal sequence influence the expression and the secretion of the protein. To the best of our knowledge, this is the first report addressing the functional consequences of the mutations in the signal peptide of porcine GH gene.

Abstract
Background A major reduction of genetic diversity in mtDNA occurred during the domestication of East Asian pigs. However, the extent to which genetic diversity has been lost in the nuclear genome is uncertain. To reveal levels and patterns of nucleotide diversity and to elucidate the genetic relationships and demographic history of domestic pigs and their ancestors, wild boars, we investigated 14 nuclear markers (including 8 functional genes, 2 pseudogenes and 4 intergenic regions) from 11 different chromosomes in East Asia-wide samples and pooled them with previously obtained mtDNA data for a combined analysis. Principal Findings The results indicated that domestic pigs and wild boars possess comparable levels of nucleotide diversity across the nuclear genome, which is inconsistent with patterns that have been found in mitochondrial genome. Conclusions This incongruence between the mtDNA and nuclear genomes is suggestive of a large-scale backcross between male wild boars and female domestic pigs in East Asia. Our data reveal the impacts of founder effects and backcross on the pig genome and help us better understand the complex demographic histories of East Asian pigs, which will be useful for future work on artificial selection.

Abstract
Dogfish (Squalus acanthias) growth hormone (GH) was identified by cDNA cloning and protein purification from the pituitary gland. Dogfish GH cDNA encoded a prehormone of 210 amino acids (aa). Sequence analysis of purified GH revealed that the prehormone is composed of a signal peptide of 27 aa and a mature protein of 183 aa. Dogfish GH showed 94% sequence identity with blue shark GH, and also showed 37-66%, 26%, and 48-67% sequence identity with GH from osteichtyes, an agnathan, and tetrapods. The site of production was identified through immunocytochemistry to be cells of the proximal pars distalis of the pituitary gland. Dogfish GH stimulates both insulin-like growth factor-I and II mRNA levels in dogfish liver in vitro. The dogfish GH gene consisted of five exons and four introns, the same as in lamprey, teleosts such as cypriniforms and siluriforms, and tetrapods. The 5'-flanking region within 1082 bp of the transcription start site contained consensus sequences for the TATA box, Pit-1/GHF-1, CRE, TRE, and ERE. These results show that the endocrine mechanism for growth stimulation by the GH-IGF axis was established at an early stage of vertebrate evolution, and that the 5-exon-type gene organization might reflect the structure of the ancestral gene for the GH gene family.

Abstract
Growth hormone (GH) belongs to a family of pituitary hormones together with prolactin and somatolactin. In our previous study, GH and its cDNA were identified in the pituitary gland of the sea lamprey, Petromyzon marinus, an extant representative of the most ancient class of vertebrates, and isolated GH stimulated expression of insulin-like growth factor in the liver. The evidence suggests that GH is the ancestral hormone in the molecular evolution of the GH/PRL/SL family and that the endocrine mechanism for growth stimulation was established at an early stage in the evolution of vertebrates. To further understand the molecular evolution of the GH/PRL/SL gene family, we report the genomic structure of sea lamprey GH including its 5'-flanking region, being cloned by PCR using specific primers prepared from its cDNA. The sea lamprey GH gene consists of 13,604 bp, making it the largest of all the GH genes. The 5'-flanking region within 697 bp contains consensus sequences for a TATA box, two Pit-1/GHF-1, three TRE, and a CRE. The sea lamprey GH gene consists of five exons and four introns, the same as in mammals, birds, and teleosts such as cypriniforms and siluriforms with the exception of some teleosts such as salmoniforms, percififorms, and tetradontiforms, in which there is an additional intron in the 5th exon. The 5-exon-type gene organization might reflect the structure of the ancestral gene for the GH/PRL/SL gene family.

Abstract
The molecular evolution of all available avian growth hormone (GH) gene sequences was investigated using both maximum-likelihood and parsimony methods, and the patterns compared to those found in mammals. In contrast to the rapid bursts of evolution observed for mammalian GH, the evolutionary rate of the avian GH mature peptide appears to have been more constant. However several positively selected sites were identified at functionally important positions in the avian signal peptide by the site-specific likelihood method. This implies that sequence variation in the avian GH signal peptide may be adaptive, although more conservative parsimony methods failed to confirm this. Nevertheless, the differing patterns of avian and mammalian GH signal peptide molecular evolution are consistent with the apparently differing roles of GH in controlling growth in these taxonomic groups and support the hypothesis that signal peptide sequence variation may in fact be the basis for increased functional complexity.

Abstract
Well-spread meiotic pachytene bivalents were obtained by using the prolonged hypotonic treatment combined with high chloroform Carnory's fixative solution from cells of the testes of domestic pigs. Comparison in the division index and length of pachytene bivalents with metaphase chromosomes showed that those of the former are 5 times higher and 3.42(1.87-5.98) times longer than those of the latter. Comparative studies on chromomere maps of bivalents and mitotic chromosomal G-bands were conducted by using the chromosome 12 as a example. Sex vesicle and various shapes of synaptic sex chromosomes have been observed. Two-color PRimed IN Situ (PRINS) labeling has been conducted successfully on pachytene bivalents of pigs.

Abstract
The growth hormone cDNAs from three different economically important animal species of indian origin viz., indian zebu cattle (Bos indicus), indian reverine buffalo (Bubalus bubalis), and beetal goat (Capra hircus) were isolated by the RT-PCR technique. The amplified product was then cloned into phagemid pBluescriptIIKS- and the nucleotide sequence of the entire 573 base coding region for each product was determined. The genetic sequences as well as the translated protein sequence of these ruminant species were compared to that of closely related species like taurine cattle (Bos taurus) and sheep (Ovis aries). A very high degree of nucleotide sequence homology, ranging between 97-98%, was observed. Subsequently, the buffalo and goat cDNAs were used for expression studies in Escherichia coli. Very low levels of expression resulted when the growth hormone cDNAs were directly placed under the strong E. coli (trc) or phage (T7) promoters with the approximate level being less than 0.1% and 1% of the intracellular E. coli proteins, respectively. The nearly 10-fold enhancement of the level of expression as observed was attributable to the nature of the untranslated leader sequence donated by the individual expression element. High level (about 20% of soluble E. coli protein) expression of buffalo/goat growth hormone was achieved as a fusion protein with glutathione-s-transferase (GST) in pGEX-KT. Further, although attempts at converting the GST-GH fusion protein system to a two-cistronic gene expression system were unsuccessful, the utilization of a short synthetic first cistron in the two-cistronic mode of expression resulted in high levels (approximately 30% of soluble protein cell fraction) of GH polypeptide with a native N-terminus in E. coli for all three cDNAs.

Abstract
The growth hormone cDNAs of Indian reverine buffalo (Bubalus bubalis) and beetal goat (Capra hircus) were cloned in Escherichia coli through RT-PCR technique. Nucleotide sequencing revealed several silent mutations in both cDNAs and only one amino acid change in the case of goat when compared to reported bovine (Bos taurus) sequence. The high level expression of both the polypeptide hormones was achieved in E. coli (> or =30% of soluble intracellular proteins) through the construction of two-cistronic gene expression system. The solubilisation of recombinant growth hormones from inclusion bodies and subsequent oxidation to correctly folded monomeric form was also carried out. A combination of reverse-phase HPLC and non-reducing SDS-PAGE was successfully applied to distinguish between reduced and oxidised forms of growth hormones. A moderate yield ( approximately 40% of starting material, with potential for upscaling), two-step purification process comprising of hydrophobic interaction and ion-exchange chromatographies was developed. The process eliminates the need for costly, laborious and time-consuming steps of ultrafiltration and dialysis, as reported earlier for the purification of many recombinant animal growth hormones. The biophysical, biochemical and functional analyses of purified refolded polypeptides showed that the hormones produced in this study were identical to natural pituitary bovine growth hormone.

Abstract
Chinese Meishan pigs develop rapidly with onset of puberty at less than 100 days of age, and have a smaller placental size and larger litter size as compared with British/Continental breeds. POU1F1 is a member of the POU-domain family gene and is a positive regulator for growth hormone (GH), prolactin (PRL), and thyroid-stimulating hormone beta (TSHbeta) in several mammalian species. To investigate the role of POU1F1 in controlling pig growth and reproduction traits, Meishan (MS) pigs segregating a MspI POU1F1 polymorphism were used to determine differences of GH and PRL at both mRNA and circulating hormone concentrations. Animals from nine litters were used to collect pituitary (n=60) and/or blood samples (n=80) at day 0, 15, and 30 after birth, and all animals were genotyped (CC, CD, DD) for the MspI POU1F1 polymorphism. Reverse transcriptase-polymerase chain reaction (RT-PCR) with standard curve quantification was used to quantify mRNA levels for GH, PRL, and two alternative POU1F1 transcripts, POU1F1-alpha, and POU1F1-beta. Radioimmunoassays were done to determine the circulating concentration of GH and PRL in blood plasma. Our results indicated a significant effect of POU1F1 genotype on circulating levels of both GH and PRL at birth, but not thereafter. The DD neonates had lower levels of GH, but higher levels of PRL, than other genotypes. POU1F1-alpha mRNA decreased (P<0.05) from days 0 to 30, which paralleled decreases (P<0.05) in GH mRNA as well as PRL and GH plasma levels over the same period. POU1F1-beta mRNA levels did not significantly change over this period. Correlations were significant between POU1F1-alpha mRNA and both GH mRNA and GH plasma concentration levels, as well as between the two POU1F1 mRNA isoforms. Results from this study add to our understanding of the role of POU1F1 in controlling pig development and reproduction.

Abstract
In mammals the sequence of pituitary growth hormone (GH) is generally strongly conserved, indicating a slow basal rate of molecular evolution. However, on two occasions, during the evolution of primates and that of cetartiodactyls, the rate of evolution has increased dramatically (25 to 50-fold) so that the sequences of human and ruminant GHs differ markedly from those of other mammalian GHs. To define further the burst of GH evolution that occurred in cetartiodactyls, the GH gene of the chevrotain (Tragulus javanicus) has been cloned and characterized by use of genomic DNA and a polymerase chain reaction technique. Two very similar gene sequences, which probably reflect allelic variation, were isolated. The deduced sequence for the mature chevrotain GH differs from that of the bovine or red deer GH at only two to three residues, and phylogenetic analysis shows that the burst of rapid evolution of GH that occurred in the Cetartiodactyla must have been completed before the divergence of the Tragulidae and the advanced ruminants (Pecora). The rate of evolution during this burst must therefore have been greater than previously estimated. In other aspects (including signal sequence, 5' upstream sequence, and synonymous substitutions in the coding sequence), the chevrotain GH gene differs considerably from the GH genes of other ruminants and here there is no evidence for the period of accelerated evolution that is seen for GH itself.

Abstract
Chicken growth hormone (cGH), a polypeptide hormone synthesized in and secreted by the pituitary gland, is involved in a wide variety of physiological functions such as growth, body composition, egg production, aging, and reproduction. Chicken growth hormone polymorphisms have been reported to be associated with certain phenotypes. Our objective is to investigate the GH gene polymorphism in selected strains of native Chinese chickens. Yellow Wai Chow GH gene was characterized by sequencing and was found to have one silent substitution, 31 insertions, and other substitutions spread among the introns. In addition, a novel Mspl site has been identified and characterized in the first intron. Allele frequencies of the intron 1 polymorphism were characterized among 28 populations of native Chinese chickens. Thus, polymorphism of the cGH gene may be useful in phylogenetic analysis, as well as in the design of breeding programs.

Abstract
This study investigated the restriction fragment length polymorphism (RFLP) of the porcine growth hormone (pGH) gene in Duroc, Landrace, and Tao-Yuan pigs and its effects on growth performance and levels of plasma growth hormone in peripheral circulation. Genomic DNA extracted from 81 Tao-Yuan, 60 Landrace and 48 Duroc pigs were subjected to Southern blot hybridization with a pGH cDNA probe. Polymorphism was detected with the restriction enzymes TaqI and DraI. A comparison of these three breeds showed significant differences in allelic frequencies. Blood samples for radioimmunoassay (RIA) of GH were collected biweekly during the experimental period from pigs 12 to 40 weeks of age. Tao-Yuan pigs showed a mean plasma GH level (2.51 +/- 1.23 ng/mL) that was much lower than that of the Landrace (3.80 +/- 1.52 ng/mL) and Duroc (4.20 +/- 1.03 ng/mL) pigs (P < 0.05). Moreover, the Tao-Yuan pigs also showed poorer growth performance than the Landrace and the Duroc pigs both in the daily weight gain (0.37 +/- 0.06 vs. 0.67 +/- 0.05 and 0.70 +/- 0.05 kg/day, P < 0.01) and feed efficiency (3.12 +/- 0.28 vs. 2.60 +/- 0.14 and 2.52 +/- 0.12, P < 0.05). These results suggest that the growth performance trait in these pigs is highly correlated with their growth hormone genotype.

Abstract
The growth hormone (GH) gene of the gilthead seabream (Sparus aurata) (saGH) has been cloned, sequenced, and characterized. The saGH gene spans approximately 4.3 kb and consists of six exons and five introns, as found for all cloned teleost GH genes with the exception of carps and catfish. The first and third introns contain long stretches of repetitive tandem repeats. The second intron, which is unusually long compared with that in other teleosts (and other vertebrates) spans 1747 nucleotides (nt) and contains several inverted repeats. Intron-targeted polymerase chain reaction (PCR) analysis identified length polymorphism of the first intron. Sequence analysis of four variants (405, 424, 636, and 720 nt) out of many variants found revealed that the variation in length is due to differences in the number of repeat monomers (17-mer or 15-mer) as well as minor changes in their length. This repeat unit contains the consensus half-site motif of the thyroid hormone response element (TRE) and estrogen response element (ERE). Polymorphism was found also in the third intron. This is the first report of such high polymorphism of the first intron of GH gene in a vertebrate.

Abstract
The cDNA for Bubalus bubalis growth hormone (GH) has been cloned and sequence determined through RT-PCR approach. The nucleotide sequence of bubaline GH cDNA was in a single reading frame coding for a protein of 191 residues comprising a putative signal sequence of 27 amino acids. Homology comparison of the sequence with other mammalian GH cDNAs showed a very high degree of evolutionary conservation. Bubaline GH sequence shared a homology of 99.5%, 99.5%, 98.6%, 87.6% and 61.9% with that of ovine, caprine, bovine, porcine and human, respectively at amino acid level.

Abstract
A gene encoding the Tilapia mossambica (Oreochromis mossambicus) growth hormone (tiGH) was isolated and sequenced. The gene spans 5.6 kb, including 3.7 kb of 5' and 0.2 kb of 3' flanking sequences and a 1.7-kb transcription unit comprised of six exons and five introns. The gene and the 5' flanking region contain several potential binding sites for Pit-1, a key transcription activator of mammalian GH genes. One of these (-57/-42) is highly conserved in fish GH genes. It activates transcription in pituitary cells and binds Pit-1. Transfection of luciferase reporter plasmids containing either the -3602/+19 tiGH sequence or one of its 5' deletion mutants (-2863/, -1292/, and -463/+19) resulted in strong activity in Pit-1-producing rat pituitary GC cells. A dose-dependent activation of the tiGH promoter was achieved in nonpituitary fish EPC and monkey COS cells cotransfected with a rat Pit-1 expression vector, demonstrating the crucial role played by Pit-1 as an activator of the tiGH gene. Fusion of the tiGH promoter with the beta-galactosidase gene led to transient expression specifically in the nervous system of microinjected zebrafish embryos. The activity of the tiGH promoter in GC and EPC cells was strongly repressed by extending its 3' end from +19 to +40, a sequence in which a Pit-1-binding site was identified using gel retardation assays. Point mutations of the site that suppressed Pit-1 binding in vitro restored full tiGH promoter activity. Thus, a Pit-1-binding site located in the 5' untranslated region mediates Pit-1-dependent repression of the tiGH gene.

Abstract
Characterization of the prolactin (PRL) amino acid (aa) or cDNA sequences has not been reported for any member of the Felidae family. We cloned cat growth hormone (cGH) and cat PRL (cPRL) cDNA sequences from a feline pituitary cDNA library. High homology between species allowed bovine PRL(bPRL) and bGH cDNA clones to be used to identify clones encoding the 229-aa cPRL and 216-aa cGH sequences. The cGH protein is most homologous to pig and dog GH. Similarly, cPRL shares the most aa identity to pig PRL (pPRL). Northern blot analysis revealed the mRNA size for cGH and cPRL to be approx. 1 and 1.1 kb, respectively. These results reveal that GH and PRL from the Felidae family are highly conserved to other families of GH and PRL.

Abstract
The gene encoding growth hormone (GH) has been cloned from a rabbit genomic library, and its sequence has been determined. The rabbit GH gene is similar to other mammalian GH, being comprised of five exons and four introns. As in rodents and artiodactyls, the rabbit GH occurs as a single gene, with no evidence for a cluster of GH-like genes, as is found in primates. The amino acid sequence of rabbit GH is similar to that of pig GH and other conserved mammalian GH, and, like these, differs markedly from the available sequences of ruminant and primate GH. This provides further support for the idea that, in mammals, GH show a slow underlying rate of evolution which has increased markedly on at least two occasions.

Abstract
In this work the growth hormone-encoding gene (GH) from the fish barramundi (Lates calcarifer) was characterized by nucleotide (nt) sequence analysis and comparative studies on higher and lower vertebrate GH were performed. The barramundi GH contains six exons and five introns. A putative transcription start point 21 nt downstream from a potential TATAAA box was determined, with a modified primary transcript size of 1615 nt predicted. cis-Acting elements potentially important for transcriptional regulation at the basal, hormone-responsive and pituitary gland-specific levels were identified. Several microsatellite and minisatellite repetitive sequences were shown to be present within noncoding portions of this gene. Repeat sequences similar to the deca- and undeca-minisatellites of the barramundi GH were observed in the corresponding introns of the tilapia, but not other teleost GH. Comparative studies on the Osteichthyes, Mammalia and Aves vertebrate class GH promoters suggested that the TATAAA box was the only conserved region between these sequences. Conserved sequences, however, were identified within the GH promoters of different species from the Osteichthyes or Mammalia classes. The Osteichthyes A + T-rich sequence (consensus GATRMATYWAAWCA, where R = A or G; M = A or C, Y = C or T and W = A or T) is the only conserved region identified between teleost GH promoters, and is most likely involved in the pituitary gland-specific expression of these genes.

Abstract
cDNA clones encoding giant catfish (Pangasianodon gigas) growth hormone (GH) have been isolated using a polymerase chain reaction (PCR) strategy. Pairwise combinations of degenerate and general primers allowed for the amplification of regions both 3' and 5' to the point of entry into the message. The amplified PCR products were cloned and sequenced. The cDNA sequence was found to encode a polypeptide of 200 amino acids (aa), including a putative signal peptide of 22 aa. The 5' and 3' untranslated regions of the message are 58 and 515 nucleotides long, respectively. The giant catfish GH displays the highest aa sequence homology with the carp GH, with 80% of sequence identity. Moreover, giant catfish GH has structural features in common with both mammalian and avian GH polypeptides, and also contains the domains of conserved sequence found in other GH.

Abstract
The molecular basis for several apparent restriction fragment length polymorphisms of the porcine growth hormone gene was examined through DNA sequence analysis. Electrophoretic and sequence analysis suggest polymorphisms result from 1-3 base substitutions that affect double-strand DNA conformation and electrophoretic mobility. Two allelic forms of the porcine growth hormone 5' flank and four allelic forms of the second exon/intron region were identified. A marker system was developed which combined conformation polymorphisms with HaeII and DdeI RFLPs. Using this system, nine haplotypes were observed in samples from three US swine breeds. The data presented suggest that double-strand DNA conformation can be exploited in base substitution detection and development of highly polymorphic genetic marker systems.

Abstract
The gene encoding the porcine growth hormone (GH) has been localized to the q-arm of chromosome 12 using high-resolution R-banded chromosomes for in situ hybridization. We report here the localization of GH on the p-arm of this chromosome when using in situ hybridization on high-resolution G-banded chromosomes. Sequential Q- and R-banding show that this discrepancy is caused by a reversed orientation of chromosome 12 in the R-banded high-resolution karyotype published by Rønne et al. (1987) and the G-banded standard karyotype.

Abstract
The growth-hormone (GH) gene of grass carp, one of the fastest-growing species of farmed fish, was isolated and the DNA sequenced. Only one GH gene is found in this species. This gene, which is 2.5 kb in length, has five exons and four introns, in common with all of the mammalian and the recently published common-carp GH genes. In the course of vertebrate evolution, the total lengths of the intron and the non-coding region of exon 5 of the GH gene have been shortened by 40-70%, whereas the encoding exons of the gene have been slightly increased. The more closely related species exhibit the closest sequence similarity in their GH genes. For example, the similarity of the exons is 84.1-93.2% between grass carp and common carp (within the same family of Syprinedae), 43.5-82.1% between grass carp and rainbow trout (in different orders of Teleostei) and 45.8-58.6% between grass carp and rat (in different grades of Vertebrata). In addition, similar DNA domains, such as thyroid-hormone-receptor-complex-binding site and cell-type-specific cis elements involved in regulation of expression of rat and human GH genes, have been localized in the corresponding regions of the grass-carp GH gene.

Abstract
We report here the nucleotide (nt) sequence of the growth hormone (GH)-encoding gene (GH) of the tilapia fish (Tilapia nilotica). The T. nilotica GH gene, similar to that of the salmonidae fish, Atlantic salmon and rainbow trout, contains six exons and five introns. However, despite the presence of an additional intron (intron V), the size of the primary transcript of T. nilotica GH (1666 nt) is significantly shorter than that of all other currently characterized fish GH genes. Comparison of sequences upstream from the transcription start point of the tilapia, carp, rainbow trout and Atlantic salmon GH genes shows a region of high homology preceding the typical TATA box. This homology does not seem to extend to the regions further upstream of the compared fish GH genes and is not observed to be present in the corresponding region of the mammalian GH genes. A sequences search for putative DNA-binding domains for transcription factors shows the presence of short nt stretches similar to those considered to be involved in the tissue-specific expression of mammalian GH genes.

Abstract
We have cloned the chicken (c) growth hormone (GH)-encoding gene cGH and analyzed its nucleotide sequence including 500 bp of the 5'-flanking region. The cGH gene consists of five exons and four introns as has been observed in the mammalian GH genes. However, the size of the cGH gene is significantly larger than that of analogous mammalian genes, because of its intron size which expands it to 3.5 kb. The transcription start point was determined to be 56 bp upstream from the start codon by the primer-extension analysis. The promoter region of the cGH gene has no overall homology with the corresponding regions of mammalian genes, but contains a short (24 bp) sequence which is highly homologous to the antisense strand sequence of the proximal binding site for a pituitary-specific transcription factor, GHF-1/Pit-1, in the promoter region of the rat GH gene.

Abstract
The cDNA clones encoding gilthead seabream (gsb) (Sparus aurata) growth hormone (GH) have been isolated from a cDNA library prepared from seabream pituitary gland poly(A)+ RNA. The cDNA library was screened using red seabream and rainbow trout GH cDNAs. The complete nucleotide (nt) sequence of gsbGH has been determined. The cDNA sequence codes for a polypeptide of 204 amino acids (aa), including a putative signal peptide of 17 aa. The 5'- and 3'-untranslated regions of the message are 55 and 236 nt long, respectively. The predicted aa sequence of gsbGH revealed 97% homology with red seabream GH, 95% with tuna GH, 85% with yellowtail GH, and 65% with rainbow trout GH.

Abstract
A cDNA clone for mink growth hormone (GH) was isolated from a mink pituitary cDNA library, employing a part of rat growth hormone cDNA sequence as a probe. According to the nucleotide sequence, mature mink GH consists of 190 amino acids with a calculated molecular weight of 21,720. The amino acid sequence homology between the mature region of mink GH and those of pig GH, rat GH, bovine GH and human GH was 98.4%, 93.7%, 89.0% and 66.7%, respectively.

Abstract
We have isolated and sequenced a phase clone from a common carp (Cyprinus carpio) genomic library that carries a gene encoding growth hormone (GH). This gene consists of five exons and four introns spanning a region of about 3 kilobase pairs. Its exons correspond with one of two reported cDNAs of carp GH except for nine differences in the nucleotide sequence, while the encoded amino-acid sequences are identical. The sequence upstream from the transcription start point contains two tandem repeats of AACTCTCATG (from -85 to -62) and the typical TATA box. All the introns start with a consensus GT dinucleotide and end with AG. The arrangement of exons and introns is very similar to that seen in mammalian GH, but quite different from the GH genes of rainbow trout and Atlantic salmon.

Abstract
Porcine growth hormone (PGH) precursor cDNAs were cloned from a pituitary cDNA library constructed in lambda gt11 by immunoscreening. One of the three clones characterized contained an entire nucleotide sequence for the 216-amino-acid precursor molecule. The deduced amino-acid sequence of PGH confirmed the sequence previously reported for that of the genomic DNA of PGH except for one base difference in the coding sequence. Expression of the full-length PGH cDNA was achieved in bacteria and mammalian cells. The mammalian cell line, COS-1, produced the GH molecule which processed the signal peptide and had the same molecular weight as standard PGH, in contrast to the higher molecular weight of the bacterial product. Radioimmunoassay of the recombinant PGH produced in COS-1 cells also revealed an inhibition curve similar to that of the standard PGH.
