Abstract: In this study, by using a single nucleotide polymorphism-based method, 1350 bp cDNA sequence of porcine ankyrin repeat and SOCS box containing protein 4 (Asb4) and 1811 bp cDNA sequence of porcine growth factor receptor-bound protein 10 (Grb10) was obtained. Then we identified their imprinting status in ten tissues. Imprinting analysis showed that both alleles of Asb4 were expressed in all the tested tissues. Grb10 was paternally expressed in tongue, kidney, stomach, intestine and brain, while biallelically expressed in the others. We also used quantitative Real-time PCR to assess the expression of Grb10 in these tissues. The expression level of Grb10 was significantly different among tissues, which was the highest in lung and lowest in both small intestine and brain. These results primarily indicated that Grb10 probably was a porcine paternally expressed gene, but Asb4 was not imprinted in swine.

Key words: pig; ankyrin repeat and SOCS box containing protein 4; growth factor receptor-bound protein 10; single nucleotide polymorphism; imprinting gene
