[PMID: 25049529 PMCID: PMC4094157 DOI: 10.5713/ajas.2012.12288] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/25/2012] [Revised: 09/24/2012] [Accepted: 07/03/2012] [Indexed: 11/27/2022]
Abstract
Crosses between Korean and Landrace pigs have revealed a large quantitative trait loci (QTL) region for fat deposition in a region (89 cM) of porcine chromosome 4 (SSC4). To more finely map this QTL region and identify candidate genes for this trait, comparative mapping of pig and human chromosomes was performed in the present study. A region in the human genome that corresponds to the porcine QTL region was identified in HSA1q21. Furthermore, the LMNA gene, which is tightly associated with fat augmentation in humans, was localized to this region. Radiation hybrid (RH) mapping using a Sus scrofa RH panel localized LMNA to a region of 90.3 cM in the porcine genome, distinct from microsatellite marker S0214 (87.3 cM). Two-point analysis showed that LMNA was linked to S0214, SW1996, and S0073 on SSC4 with logarithm (base 10) of odds scores of 20.98, 17.78, and 16.73, respectively. To clone the porcine LMNA gene and to delineate the genomic structure and sequences, including the 3'untranslated region (UTR), rapid amplification of cDNA ends was performed. The coding sequence of porcine LMNA consisted of 1,719 bp, flanked by a 5'UTR and a 3'UTR. Two synonymous single nucleotide polymorphisms (SNPs) were identified in exons 3 and 7. Association tests showed that the SNP located in exon 3 (A193A) was significantly associated with weight at 30 wks (p<0.01) and crude fat content (p<0.05). This association suggests that SNPs located in LMNA could be used for marker-assisted selection in pigs.

Abstract
To understand molecular genetic characteristics of Korean pigs, the genetic relationships of nine pig breeds including two Korean pigs (Korean native pig and Korean wild pig), three Chinese pigs (Min pig, Xiang pig, and Wuzhishan pig), and four European breeds (Berkshire, Duroc, Landrace, and Yorkshire) were characterized from a 16-microsatellite loci analysis. The mean heterozygosity within breeds ranged from 0.494 to 0.703. Across multiple loci, significant deviation from Hardy-Weinberg equilibrium was observed in most pig breeds, except for two Chinese pigs (Min pig and Wuzhishan pig). This deviation was in the direction of heterozygote deficit. Across population loci, 36 of 144 significantly deviated (P < 0.05) from Hardy-Weinberg equilibrium. The mean FST, a measure of genetic divergence among subpopulations, of all loci indicated that 26.1% of total variation could be attributed to the breed difference. Relationship trees based on the Nei's DA genetic distance and scatter diagram from principal component analysis consistently displayed pronounced genetic differentiation among the Korean wild pig, Xiang pig, and Wuzhishan pig. Individual assignment test using a Bayesian method showed 100% success in assigning Korean and Chinese individual pigs into their correct breeds of origin and 100% exclusion success from all alternative reference populations at P < 0.001. These findings indicate that the Korean native pig has been experiencing progressive interbreeding with Western pig breeds after originating from a North China pig breed with a black coat color. Considering the close genetic relationship of Korean pigs to the Western breeds such as Berkshire and Landrace, our findings can be used as valuable genetic information for the preservation and further genetic improvement of the Korean native pig.

Abstract
GRN has been shown to have roles in multiple processes involved in cell growth, development and wound repair in rodents and humans. We have isolated the full-length cDNA of GRN gene encoding porcine granulin protein by in silico cloning, RT-PCR and RACE. The deduced amino acid indicated 71.5% identity with the corresponding human sequence and the seven and one-half granulins showed highly conservative between pig, human and murine. A single nucleotide substitution resulting in the amino acid change (ATG/Met --> TTG/Leu) was detected within exon 5. Allele frequencies in six pig breeds showed distinctive differences between those Chinese indigenous pig breeds and European pigs. Using the IMpRH panel, we mapped the porcine GRN gene to porcine chromosome 12p11-p13. Our data provide basic molecular information useful for the further investigation on the function of GRN gene.

Abstract
We have previously identified and mapped porcine expressed sequence tags (ESTs) derived from genes that are preferentially expressed in liver. The aim of the present study was to identify single nucleotide polymorphisms (SNPs) in porcine genes encoding enzymes in hepatic metabolic pathways and use the SNPs for mapping. Furthermore, these genes, which are involved in utilization and partitioning of nutrients, were examined for their effects on carcass and meat quality traits by linkage analyses. In total, 100 ESTs were screened for SNPs by single strand conformation polymorphism analyses across a diverse panel of animals with a 36% success rate. Twelve of 36 polymorphic loci segregated in a three-generation Duroc x Berlin Miniature Pig (F2) resource population, the DUMI resource population, and were genetically mapped. Interval mapping of the corresponding chromosomes was performed to verify mapping of the genes within quantitative trait loci (QTL) regions detected in this resource population. QTL with genome-wide significance were detected in the vicinity of GNMT, ESTL147 and HGD. These loci therefore are positional candidate genes.

Abstract
Previously, quantitative trait loci (QTL) for tenth-rib backfat (TENTHRIB) and loin eye area (LEA) were identified on pig Chromosome 1 (SSC 1) near microsatellite S0008 from a three-generation Berkshire x Yorkshire cross (BY). This work attempted to refine these QTL positions and identify genes associated with these QTL. Genotypes of BY (n = 555) were determined by PCR-RFLP or PCR tests for 13 polymorphisms identified in BY F(0) individuals for candidate genes, BAC end sequences, and genomic clones. Using least-squares regression interval mapping, the LEA QTL was estimated at S0008; the TENTHRIB QTL position was shifted approximately 1 cM downstream from S0008. Of the genes/sequences mapped in the QTL region, CL349415 was significantly associated with TENTHRIB (p = 0.02) and solute carrier family 2, member 12 (SLC2A12) was significantly associated with LEA (p = 0.02). These results suggest that the gene(s) responsible for the LEA and TENTHRIB QTL effects are tightly linked to S0008 or that the high informativeness of S0008 relative to surrounding markers is influencing the QTL position estimates. In addition, janus kinase 2 (JAK2) was mapped to a suggestive LEA QTL region and showed association with LEA (p = 0.009), fatness, color, and pH traits in BY.

Abstract
Angiopoietin-like protein 3 and -4 (ANGPTL3 and -4) are two members of angiopoietin-like proteins (ANGPTLs), which have the signature structure of the angiopoietin family but cannot bind to the TIE2 receptor. It has been reported that they both affect lipid metabolism by inhibiting the activity of lipoprotein lipase (LPL). Here we report the cDNA cloning, chromosome mapping and expression analysis of ANGPTL3 and -4 in pigs. Sequence analysis shows that ANGPTL3 contains an open reading frame of 1,389 bp, which encodes 462 amino acids, and ANGPTL4 contains a coding region of 1,239 bp, which encodes 412 amino acids. Porcine ANGPTL3 deduced amino acid sequence shares 83% and 73.7% identity with human and mouse, respectively, and ANGPTL4 shares 79.4% and 77.7% amino acid identity with human and mouse, respectively. Porcine ANGPTL3 and -4 were mapped to the 6q31-->q35 and 2q21-->q24 region, respectively, by radiation hybrid mapping. Tissue distribution analysis indicated that porcine ANGPTL3 mRNA was exclusively expressed in liver, and porcine ANGPTL4 was ubiquitously expressed with the highest abundance in white adipose tissue. Furthermore, the mRNA level of ANGPTL3 and -4 in liver and the mRNA level of ANGPTL4 in white adipose tissue were significantly higher in genetically obese pigs than in their lean counterparts. This is the first report of molecular cloning and characterization of ANGPTL3 and -4 in pigs, which will be helpful for a better understanding of the role of ANGPTLs in lipid metabolism.

Abstract
BACKGROUND Inguinal and scrotal hernias are of great concern to pig producers, and lead to poor animal welfare and severe economic loss. Selection against these conditions is highly preferable, but at this time no gene, Quantitative Trait Loci (QTL), or mode of inheritance has been identified in pigs or in any other species. Therefore, a complete genome scan was performed in order to identify genomic regions affecting inguinal and scrotal hernias in pigs. Records from seedstock breeding farms were collected. No clinical examinations were executed on the pigs and there was therefore no distinction between inguinal and scrotal hernias. The genome scan utilised affected sib pairs (ASP), and the data was analysed using both an ASP test based on Non-parametric Linkage (NPL) analysis, and a Transmission Disequilibrium Test (TDT). RESULTS Significant QTLs (p < 0.01) were detected on 8 out of 19 porcine chromosomes. The most promising QTLs, however, were detected in SSC1, SSC2, SSC5, SSC6, SSC15, SSC17 and SSCX; all of these regions showed either statistical significance with both statistical methods, or convincing significance with one of the methods. Haplotypes from these suggestive QTL regions were constructed and analysed with TDT. Of these, six different haplotypes were found to be differently transmitted (p < 0.01) to healthy and affected pigs. The most interesting result was one haplotype on SSC5 that was found to be transmitted to hernia pigs with four times higher frequency than to healthy pigs (p < 0.00005). CONCLUSION For the first time in any species, a genome scan has revealed suggestive QTLs for inguinal and scrotal hernias. While this study permitted the detection of chromosomal regions only, it is interesting to note that several promising candidate genes, including INSL3, MIS, and CGRP, are located within the highly significant QTL regions. Further studies are required in order to narrow down the suggestive QTL regions, investigate the candidate genes, and to confirm the suggestive QTLs in other populations. The haplotype associated with inguinal and scrotal hernias may help in achieving selection against the disorder.

Abstract
BACKGROUND Zygote arrest 1 (ZAR1) is one of the few known oocyte-specific maternal-effect genes essential for the beginning of embryo development discovered in mice. This gene is evolutionary conserved in vertebrates and ZAR1 protein is characterized by the presence of atypical plant homeobox zing finger domain, suggesting its role in transcription regulation. This work was aimed at the study of this gene, which could be one of the key regulators of successful preimplantation development of domestic animals, in pig and cattle, as compared with human. METHODS Screenings of somatic cell hybrid panels and in silico research were performed to characterize ZAR1 chromosome localization and sequences. Rapid amplification of cDNA ends was used to obtain full-length cDNAs. Spatio-temporal mRNA expression patterns were studied using Northern blot, reverse transcription coupled to polymerase chain reaction and in situ hybridization. RESULTS We demonstrated that ZAR1 is a single copy gene, positioned on chromosome 8 in pig and 6 in cattle, and several variants of correspondent cDNA were cloned from oocytes. Sequence analysis of ZAR1 cDNAs evidenced numerous short inverted repeats within the coding sequences and putative Pumilio-binding and embryo-deadenylation elements within the 3'-untranslated regions, indicating the potential regulation ways. We showed that ZAR1 expressed exclusively in oocytes in pig ovary, persisted during first cleavages in embryos developed in vivo and declined sharply in morulae and blastocysts. ZAR1 mRNA was also detected in testis, and, at lower level, in hypothalamus and pituitary in both species. For the first time, ZAR1 was localized in testicular germ cells, notably in round spermatids. In addition, in pig, cattle and human only shorter ZAR1 transcript variants resulting from alternative splicing were found in testis as compared to oocyte. CONCLUSION Our data suggest that in addition to its role in early embryo development highlighted by expression pattern of full-length transcript in oocytes and early embryos, ZAR1 could also be implicated in the regulation of meiosis and post meiotic differentiation of male and female germ cells through expression of shorter splicing variants. Species conservation of ZAR1 expression and regulation underlines the central role of this gene in early reproductive processes.

Abstract
We have cloned and characterized the gene encoding the porcine cationic amino acid transporter, member 1 (CAT-1) (HGMW-approved gene symbol SLC7A1) from porcine pulmonary artery endothelial cells. The porcine SLC7A1 encodes 629 deduced amino acid residues showing a higher degree of sequence similarity with the human counterpart (91.1%) than with the rat (87.3%) and mouse (87.6%) counterparts. Confocal microscopic examination of porcine CAT-1-GFP-expressing HEK293 cells revealed that porcine CAT-1 localizes on the plasma membrane. Amino acid uptake studies in Xenopus oocytes injected with cRNA encoding this protein demonstrated transport properties consistent with system y(+). Radiation hybrid mapping data indicate that the porcine SLC7A1 maps to the distal end of the short arm of pig chromosome 11 (SSC11). This map location is consistent with the known conservation of genome organization between human and pig and provides further confirmation that we have characterized the porcine orthologue of the human SLC7A1.

Abstract
Genes located on human chromosome 12 (HSA12) are conserved on pig chromosomes 5 and 14 (SSC5 and SSC14), with HSA12q23.3-->q24.11 harboring the evolutionary breakpoint between these chromosomes. For this study, pig sequence-tagged sites (STS) were developed for nine HSA12 genes flanking this breakpoint. Radiation hybrid (RH) mapping using the IMpRH panel revealed that COL2A1, DUSP6, KITLG, PAH and STAB2 map to SSC5, while PXN, PLA2G1B, SART3 and TCF1 map to SSC14. Polymorphisms identified in COL2A1, DUSP6, PAH, PLA2G1B and TCF1 were used for genetic linkage mapping and confirmed the map locations for these genes. Our results indicate that the HSA12 evolutionary breakpoint occurs between STAB2 and SART3 in a region spanning less than five million basepairs. These results refine the comparative map of the HSA12 evolutionary breakpoint region and help to further elucidate the extensive gene order rearrangements between HSA12 and SSC5 and 14.

Abstract
The GENETPIG database has been established for storing and disseminating the results of the European project: 'GENETPIG: identification of genes controlling economic traits in pig'. The partners of this project have mapped about 630 porcine and human ESTs onto the pig genome. The database collects the mapping results and links them to other sources of mapping data; this includes pig maps as well as available comparative mapping information. Functional annotation of the mapped ESTs is also given when a significant similarity to cognate genes was established. The database is accessible for consultation via the Internet at http://www.infobiogen.fr/services/Genetpig/.

Abstract
Increasing the number of mapped genes will facilitate (1) the identification of potential candidate genes for a trait of interest within quantitative trait loci regions and (2) comparative mapping. The metabolic activities of the liver are essential for providing fuel to peripheral organs, for regulation of amino acid, carbohydrate and lipid metabolism and for homoeostasis of vitamins, minerals and electrolytes. We aimed to identify and map genes coding for enzymes active in the liver by somatic cell genetics in order to contribute to the improvement of the porcine gene map. We mapped 28 genes of hepatic metabolic pathways including six genes whose locations could be confirmed and 22 new assignments. Localization information in human was available for all but one gene. In total 24 genes were assigned to in the expected chromosomal regions on the basis of the currently available information on the comparative human and pig map while for four genes our results suggest a new correspondence or extended regions of conservation between porcine and human chromosomes.

Abstract
A comparative map of human chromosome 12 (HSA 12) and pig chromosome 5 (SSC 5) was constructed using ten pig expressed sequence tags (ESTs). These ESTs were isolated from primary granulosa cell cultures by differential display (EST b10b), or from a granulosa cDNA library (VIIIE1, DRIM, N*9, RIIID2 and RVIC1) or from a small intestine cDNA library (ATPSB, ITGB7, MYH9, and STAT2). Also used were two Traced Orthologous Amplified Sequence Tags (TOASTs) (LALBA, TRA1), one microsatellite-associated gene (IGF1) and finally five human YACs selected for their cytogenetic position, with a view to increasing the number of informative markers for the comparison. Large-insert clones were obtained by screening a pig bacterial artificial chromosome (BAC) library with specific primers for each EST and TOAST and for IGF1. These BACs were used as probes for fluorescent in situ hybridisation (FISH) both on porcine and human metaphases. In addition, the human YACs were FISH mapped on pig chromosomes. This allowed us to refine and, in some cases, to correct the previous mapping obtained with a somatic cell hybrid panel. While these data confirm chromosome painting results showing that the distal part of SSC 5p arm is conserved on HSA 22, while the rest of the chromosome corresponds to HSA 12, they also demonstrate gene-order differences between human and pig. In addition, it was also possible to determine the position of the synteny breakpoint.

Abstract
Comparative anchor tagged sequence (CATS) consensus primers from loci mapped to human chromosomes 9, 10, 20, and 22 have been used to amplify homologous loci in pigs. Of 53, CATS primers tested in pigs, only 23 yielded products homologous to the human locus (42% success). Ten loci were physically mapped (43% success rate for verified products, but only 19% for primers tested). Due to lack of polymorphism, linkage mapping was possible only for AMBP. Map locations were consistent with human/pig ZOO-FISH, except for ADRA1A, whose position is still equivocal in humans. These CATS primers have made very limited contributions to pig/human comparative gene mapping because of low efficiency of amplification of orthologous porcine product, frequent amplification from rodent template in a somatic hybrid panel and low level of polymorphism.

Abstract
UNLABELLED In our studies of the genes constituting the porcine A0 blood group system, we have characterized a cDNA, encoding an alpha(1,3)N-acetylgalactosaminyltransferase, that putatively represents the blood group A transferase gene. The cDNA has a 1095-bp open reading frame and shares 76.9% nucleotide and 66.7% amino acid identity with the human ABO gene. Using a somatic cell hybrid panel, the cDNA was assigned to the q arm of pig chromosome 1, in the region of the erythrocyte antigen A locus (EAA), which represents the porcine blood group A transferase gene. The RNA corresponding to our cDNA was expressed in the small intestinal mucosae of pigs possessing EAA activity, whereas expression was absent in animals lacking this blood group antigen. The UDP-N-acetylgalactosamine (UDP-GalNAc) transferase activity of the gene product, expressed in Chinese hamster ovary (CHO) cells, was specific for the acceptor fucosyl-alpha(1,2)galactopyranoside; the enzyme did not use phenyl-beta-D-galactopyranoside (phenyl-beta-D-Gal) as an acceptor. Because the alpha(1,3)GalNAc transferase gene product requires an alpha(1,2)fucosylated acceptor for UDP-GalNAc transferase activity, the alpha(1,2)fucosyltransferase gene product is necessary for the functioning of the alpha(1,3)GalNAc transferase gene product. This mechanism underlies the epistatic effect of the porcine S locus on expression of the blood group A antigen. ABBREVIATIONS CDS: coding sequence; CHO: Chinese Hamster Ovary; EAA: erythrocyte antigen A; FCS: foetal calf serum; Fucalpha(1,2)Gal: fucosyl-alpha(1,2)galactopyranoside; Gal: galactopyranoside; GGTA1: Galalpha(1,3)Gal transferase; PCR: polymerase chain reaction; phenyl-beta-D-Gal: phenyl-beta-D-galactopyranoside; R: Galbeta1-4Glcbeta1-1Cer; UDP-GalNAc: uridine diphosphate N-acetylgalactosamine

Abstract
We have developed a panel of 152 whole-genome radiation hybrids by fusing irradiated diploid pig lymphocytes or fibroblasts with recipient hamster permanent cells. The number and size of the porcine chromosome fragments retained in each hybrid clone were checked by fluorescence in situ hybridization with a SINE probe or by primed in situ labeling (PRINS) with SINE-specific primers. A strategy based on the interspersed repetitive sequence polymerase chain reaction (IRS-PCR) was developed for selected clones to determine if the large fragments painted by the SINE probe corresponded to one pig chromosome or to different fragments of several chromosomes. This strategy was buttressed by a double PRINS approach using primers specific for alpha-satellite sequences of two different groups of swine chromosomes. Genome retention frequency was estimated for each clone by PCR with 32 markers localized on different porcine chromosomes. Of the 152 hybrids produced, 126 were selected on the basis of cytogenetic content and chromosome retention frequency to construct a radiation hybrid map of swine chromosome 8. Our initial results for this chromosome indicate that the resolution of the radiation hybrid map is 18 times higher than that obtained by linkage analysis.

Abstract
This study provides 53 new fluorescent in situ hybridization cytogenetic assignments for microsatellite markers linked on the swine genetic map. Forty microsatellites are physically assigned for the first time. The chromosomal locations of eight markers were either confirmed or refined, while five loci were assigned to locations different from those given in previous reports. Markers were selected to provide physical anchors based on their presumed proximity to centromeres or telomeres and at approximately 30 cM intervals across the genetic map. The number of physical anchors for pig (SSC) chromosomes 8, 15, and 18 linkage groups was significantly improved. Centromeric regions were localized to areas less than 10 cM for SSC 1, 2, 3, 6, 7, 8, and 9. Although the recombination rate was generally higher across small biarmed chromosomes and lowest for large acrocentric chromosomes, two regions with particularly low (1q2.1-->q2.9 and 13q2.3-->q4.1) and three regions with extremely high (5p1.5-->p1.2, 6p1.4-->p1.3, and 12p1.5-->p1.4) rates of recombination were detected. These assignments represent an overall 10% increase in the number of physically assigned markers in Sus scrofa and more than a 20% increase in the number of Type II loci assigned to the pig cytogenetic map.

Abstract
A comparative map of human chromosome 3 (HSA 3) and pig chromosome 13 (SSC 13) was constructed using physically assigned pig sequence-tagged sites (STSs). Pig STSs representing 11 HSA 3 genes, including v-Raf-1 murine leukemia viral oncogene homolog 1 (RAF1), retinoic acid beta receptor (RARB), cholecystokinin (CCK), pituitary transcription factor 1 (POU1F1), ceruloplasmin (CP), guanine nucleotide binding protein, alpha-inhibiting polypeptide 2 (GNAI2), sucrase-isomaltase (SI), rhodopsin (RHO), dopamine receptor D3 (DRD3), growth-associated protein 43 (GAP43), and somatostatin (SST), were developed. Ten pig STSs were regionally mapped using a somatic cell hybrid panel (SCHP) to SSC 13 with 80-100% concordance. Large-insert probes were obtained by screening a pig yeast artificial chromosome (YAC) library with primers for each STS. Several YACs were identified for DRD3, GAP43, POU1F1, RHO, SI, and SST for fluorescence in situ hybridization (FISH) mapping. Single gene and bi-color FISH with each pairwise combination were used to further define the gene order on SSC 13. While these data confirm chromosome painting results showing that HSA 3 probes hybridize to a major portion of SSC 13, they also demonstrate extensive gene-order differences between man and pig within this large conserved synteny group. Interestingly, several conserved chromosomal regions have been detected between pig and mouse that are not conserved between man and mouse, suggesting that the SSC 13 gene arrangement may be the closest to that of the ancestral eutherian chromosome.

Abstract
Previous mapping between the human and pig genomes suggested extensive conservation of human chromosome 13 (HSA13) to pig chromosome 11 (SSC11). The objectives of this study were comparative gene mapping of pig homologs of HSA13 genes and examining gene order within this conserved synteny group by physical assignment of each locus. A detailed HSA13 to SSC11 comparison was chosen since the comparative gene map is not well developed for these chromosomes and a rearranged gene order within conserved synteny groups was observed from the comparison between HSA13 and bovine chromosome 12 (BTA12). Heterologous primers for PCR were designed and used to amplify pig homologous fragments. The pig fragments were sequenced to confirm the homology. Six pig STSs (FLT1, ESD, RB1, HTR2A, EDNRB, and F10) were physically mapped using a somatic cell hybrid panel to SSC11, and fluorescent in situ hybridization (FISH) mapping was also applied to improve map resolution and determine gene order. Results from this study increase the comparative information available on SSC11 and suggest a conserved gene order on SSC11 and HSA13, in contrast to human:bovine comparisons of this syntenic group.

Abstract
The proto-oncogene c-myc codes for a nuclear phosphoprotein, a transcription factor composed of the typical basic/helix-loop-helix/leucine zipper domains. Its expression is coupled to a multitude of physiological processes and regulated by a variety of hormones, growth factors, cytokines, lymphokines and the nutritional status, development and differentiation. Its key roles have been characterized, e.g. in adipogenesis, myogenesis and folliculogenesis. We have isolated and sequenced a 6.4-kb genomic fragment encoding the porcine c-myc proto-oncogene. The gene shows the typical c-myc structure with three exons, three putative promoters and a deduced protein of 439 amino acids. The porcine c-myc was mapped to chromosome 4p13 by screening of a porcine-rodent hybrid cell panel.

Abstract
From a resource of porcine ESTs, 52 transcripts were selected for regional chromosomal assignments in a somatic cell hybrid panel. Except for six ESTs, the chosen transcripts represented genes where the BLASTX database searches showed high similarity scores (>90%) with a part of the single pass 5' sequence to human, bovine, mouse, or pig entries. PCR primers for hybrid cell analysis of the ESTs were positioned in the 3'UTR of the sequences. Confident regional assignments to pig chromosomes were obtained for 33 of the 52 porcine ESTs. Comparative human mapping data were available for 27 of these. Twenty-four proved to be orthologous genes now placed on the porcine transcription map. The data presented provide further comparative data for 13 autosomes and the X chromosome.

Abstract
Somatic cell hybrid (SCH) panels and radiation hybrid (RH) panels are powerful resources for comparative gene mapping because gene assignments are made without the detection of genetic polymorphism as needed for linkage mapping. A frequently encountered problem, however, is that the gene specific primers may amplify homologous PCR products of equal length from the donor and recipient species of the panel. Here, we describe a simple solution to this problem in which we utilize the formation of interspecies heteroduplexes that can be easily distinguished from the corresponding homoduplexes by native polyacrylamide gel electrophoresis. We denote these DNA-DNA interspecies hybrids, xenoduplexes (xeno = Gr. Xenos, foreigner). A merit of the method is that the formation of xenoduplexes strongly suggests that the PCR products from the two species represent homologous sequences. The method is thus particularly useful for comparative gene mapping when the PCR primers have been designed by use of sequence information from other species. In this study we have successfully used xenoduplex analysis and a pig-rodent SCH panel to map seven porcine genes (ACADM, AT3, HOXD, IL8RB, LEPR, PAX8, PKLR) for which no previous sequence information was available. The assignment of the leptin receptor gene (LEPR) to pig chromosome 6q32-35 excluded LEPR as a candidate gene for a QTL on pig chromosome 4 with a major effect on fatness.

Abstract
We have used a PCR-based approach for the genetical and physical mapping of 34 transcripts isolated from a porcine small intestine cDNA library. All but one gene were regionally localized by using a somatic pig-rodent cell hybrid panel, and 12 genes were mapped by linkage analysis of single-stranded conformational polymorphisms developed in 3' untranslated regions of transcripts. For 20 of the transcripts, the human homolog has already been mapped. This study thus represents a significant contribution to the pig comparative map. Some important findings were that we could clarify the extent of a previously identified inversion event in a region of conserved synteny between SSC6q and HSA1p, that SSC14q does contain a region homologous to HSA1, a situation not clear from earlier ZOO-FISH studies, and that the homology between SSC17 and HSA20 includes the p-arm of HSA20.

Abstract
Complementary DNA sequences were selected from a resource of tentatively identified clones from a porcine small intestine cDNA library. Forty PCR primer pairs were designed to amplify 101-309 base pairs of the 3' untranslated region of the genes. The PCR conditions were optimized by altering both formamide and magnesium concentrations on samples of pig, mouse, and hamster DNA. Twenty primer pairs that, under stringent conditions, were pig-specific and amplified the expected fragments were chosen for regional assignment in a pig/rodent hybrid cell panel. Furthermore, 22 primer pairs were chosen to amplify DNA from the parental animals of the PiGMaP shared reference families in order to detect possible polymorphisms. Primer pairs that generated polymorphisms were used for genetic mapping. A total of 22 porcine expressed sequence tags (ESTs) were cytogenetically or genetically mapped by this approach. Twelve of the mapped ESTs could be added to the human-porcine comparative map.

Abstract
Swine Chromosome (Chr) 6-enriched libraries, generated with size-fractionated DNA isolated from chromosomes sorted by flow cytometry, have been used to develop new Chr 6 microsatellite markers. Chromosome isolation procedures were established to reproducibly prepare high quality chromosomes from phytohemagglutinin (PHA)-stimulated swine peripheral blood lymphocytes and to sort individual chromosomes after staining with Hoechst 33258 and chromomycin A3. Chromosome purity was verified by specific staining of swine Chr 6 with fluorescence in situ hybridization (FISH) by use of painting probes generated by degenerate oligonucleotide-primed polymerase chain reaction (DOP-PCR) amplification of as few as 300 sorted Chr 6. For library construction, DNA was extracted from flow-sorted pools representing Chr 6, amplified, size selected for fragments from 300 to 700 bp, and ligated into pBluescript SK II+ or Lambda ZAP Express. The libraries were then screened with a radiolabeled poly-(dCA) DNA probe. Of 107 (CA)n repeat-containing clones verified by sequencing, 21 were polymorphic and used to genotype the University of Illinois swine reference families. Linkage analysis was then performed with CRIMAP 2.4 (LOD > 3.0), and the results showed that 15 of the microsatellites mapped to swine Chr 6. At least three of these new markers map to locations where there were gaps in the consensus Chr 6 map. Another four markers, because of their PIC values, should provide more informative markers in other areas of the map. Most of the new markers can also be used for automated genotyping with fluorescent labeling. This set of 15 new Chr 6 markers will, therefore, be useful in helping to define QTL associated with swine Chr 6.
