Abstract:

In order to reveal the imprinting status of Gab1 (Grb2-associated binding protein 1) and Sfmbt2 (Scm-like with four mbt domains 2) in different tissues and placenta of bovine, in this study, we analyzed the imprinting status of Gab1 and Sfmbt2 in 7 bovine tissues (heart, liver, spleen, lung, kidney, muscle and fat) and placenta by direct sequencing the RT-PCR products based on single nucleotide polymorphisms.The result displayed that Gab1 and Sfmbt2 were all expressed in 7 tissues and placenta.We discovered that Gab1 and Sfmbt2 were bi-allelic expressed by comparing sequence chromatograms of RT-PCR products and genomic PCR products at single nucleotide polymorphisms sites, suggesting that Gab1 and Sfmbt2 were not imprinted in adult cattle tissues and placenta.
