. "Degenerate primers based on human and mouse obesity gene (OBS) sequencing data were used in the reverse transcriptase-polymerase chain reaction (RT-PCR) of total RNA from pig white adipose tissue. Both strands of the resultant pig-specific 325 bp DNA fragment were sequenced. Comparison of the obtained sequence with known sequences revealed an 86% identity with the human and 84% identity with the mouse OBS cDNA. The OBS gene was physically mapped to pig chromosome 18 by PCR analysis of somatic cell hybrids, using pig-specific primers. This result is consistent with the recent assignment of the human OBS gene to chromosome 7 and the observation made by comparative mapping that by using a human chromosome 7 specific library two segments of conserved synteny were detected on porcine chromosomes 9 and 18. We conclude the border of conserved synteny to be in the 7q31-7q32 region of the human chromosome." . . . "Anim. Genet." . "Stranzinger G." . "Rettenberger G." . "Neuenschwander S." .
