Abstract
Previous comparative mapping suggested that at least five pig chromosomes (Sscr4, 6, 9, 10 and 14) share homology with human chromosome 1 (Hsap1). A significant quantitative trait loci (QTL) for fat deposition has been identified on Sscr4 that appears to be near the junction region between Sscr4 and Sscr9 relative to Hsap1. It is of interest to define the boundaries of conserved synteny between pig chromosomes and Hsap1 to use human map information to identify putative comparative positional candidates for this QTL. Eleven genes, including Janus kinase 1 (JAK1), Prostaglandin E receptor3 (PTGER3), urate oxidase (UOX), coagulation factor 3 (F3), vascular cell adhesion molecule 1 (VCAM1), ribosomal protein L5 (RPL5), POU domain, class 2, transcription factor 1 (POU2F1), coagulation factor 5 (F5), Prostaglandin endoperoxide synthase-2 (PTGS2), myosin binding protein H (MYBPH) and Antithrombin III (SERPINC1), were selected to refine the boundaries of the blocks of conserved synteny between Hsap1 and pig chromosomes. Pig sequence tagged sites (STSs) were developed and used to physically map these 11 genes using a somatic cell hybrid panel. Eight loci have been mapped by using fluorescent in situ hybridization (FISH) to improve map resolution. Heterologous FISH was used to refine the location of VCAM1 on human chromosomes. In addition, human yeast artificial chromosomes (YACs) were mapped by heterologous FISH on pig metaphases to refine the boundaries of the regions of homology between Sscr4 and Sscr9 on Hsap1. Results from this study suggest the precise break in conserved synteny on Hsap1 corresponding to the Sscr4/6 and Sscr4/9 transitions are most likely on the Hsap1p22 and Hsap1q24-25 regions, respectively. Further, our data predict that Hsap1q21-24 is a candidate region for the backfat QTL localized to Sscr4.

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
The aim of this study was to determine the correspondence between human and porcine chromosome fragments using whole chromosome painting probes from both species in heterologous hybridization experiments (bidirectional heterologous chromosome painting). Bidirectional experiments allow the determination of segment-to-segment homologies between the chromosomes of these two species. Chromosome-specific painting probes from both species were, except one, obtained by DOP-PCR or PARM-PCR amplification of flow-sorted chromosomes. The probes labeled 95% of the total length of the porcine chromosomes with human painting probes and 60% of the human chromosomes in the reverse experiments. Syntenic relationships of chromosomal segments on the karyotype of both species were determined. There was close agreement between com- parative gene mapping data and the identified homologous segments; this comparison enabled orientation of the segments. We demonstrate that bidirectional heterologous chromosome painting is a highly efficient way of generating comparative cytogenetic maps.

Abstract
Numerous loci can be amplified by PARM-PCR on 300 sorted chromosomes in low-stringency conditions (annealing at 30 degrees C during the two first cycles) to produce a probe that can be used in FISH painting experiments. We demonstrate that, depending on the primer chosen for the amplification, patterns of different quality can be obtained. In order to design a primer that allows amplification of coding sequences, we have shown that motifs of at least seven glutamic acid repeats (GAG or GAA codons) are present in human proteins more frequently than expected. Moreover, these repeats do not correspond to triplet expansion and can be conserved between species. Using probes prepared from sorted chromosomes with (GAG)7 primer, we were able to achieve homologous FISH painting on human, porcine, ovine, and bovine species, and bidirectional heterologous FISH painting between human and porcine species. As an example, using probes for human Chromosome (Chr) 19 and porcine Chrs 1 and 6, we clearly defined the regional homologies existing between those chromosomes.

Abstract
One of the most widely studied simple sequences in the mammalian genome is the (TG)n dinucleotide sequence. Because these microsatellites are highly polymorphic, we chose to study microsatellites from cosmids to provide genetic markers for the porcine genome. After screening a porcine cosmid library with a (CA)10 probe, 20 cosmids containing microsatellites were subcloned and 17 microsatellites identified by sequencing. Oligonucleotide primers flanking the repeat were designed for seven (TG)n microsatellites with n > 14. These seven microsatellites revealed polymorphism and were regionally assigned to chromosomes by fluorescent in situ hybridization of initial cosmids. These seven loci will be useful for both the construction of the genetic map and as landmark loci on the physical map of the porcine genome.

Abstract
Nineteen cosmids have been mapped to pig chromosomes by fluorescence in situ hybridization. Two kinds of cosmid clones were isolated as potential physical and genetic markers for the pig genome. Anonymous cosmids were obtained by screening a commercial cosmid library and were localized to Chromosomes (Chrs) 1, 2, 6, 7, 8, 10, 11, 12, 13, and 14. Some of these cosmids were found to reveal RFLP type DNA polymorphism. Microsatellite-containing cosmid clones were isolated by screening a pig cosmid library with a (CA)10 probe and were regionally mapped to Chrs 2, 6, 7, 13, and 14. Ten of the 19 chromosomes in the pig were labeled with these probes. Two-color fluorescence in situ hybridization was used to increase the efficiency of the cosmid localizations.
