Although expression and epigenetic differences of imprinted genes have been extensively characterised in man and the mouse, little is known on livestock species. In this study, the polymorphism-based approach was used to detect the imprinting status of NNAT and DIRAS3 genes in five heterozygous pigs (based on SNP) of Large White and Meishan F1 hybrids. The(More)
Grb10 gene expression was analyzed in fetus and four organs during gestation process using the real-time RT-PCR and in situ hybridization. The real-time RT-PCR analysis result showed that the expression of Grb10 in whole embryos is throughout E8.5 to E19.5. The Grb10 gene expression level was gradually increased from E8.5 to E13.5, and then gradually(More)
The Dlk1-Dio3 imprinted domain on mouse chromosome 12qF1 contains three paternally expressed protein-coding genes and multiple maternally expressed long or short noncoding RNA genes. All these imprinted genes are regulated by IG-DMR located between Dlk1 and Meg3/Gtl2. Recently, several novel imprinted noncoding RNAs were identified in the intergenic region(More)
In this report, we developed a HBV infection model in C57BL/6 mouse line by in vivo injection of a recombinant adeno-associated virus 8 vector carrying 1. 3 copies of HBV genome (ayw subtype) (rAAV8-1. 3HBV). We firstly prepared and purified the rAAV8-1. 3HBV and then injected it into three C57BL/6 mice with the dose of 2 x 10e11vg, respectively. HBsAg and(More)
The mouse delta-like homolog 1 and type III iodothyronine deiodinase (Dlk1-Dio3) imprinted domain contains three known paternally methylated differentially methylated regions (DMRs): intergenic DMR (IG-DMR), maternally expressed 3-DMR (Gtl2-DMR), and Dlk1-DMR. Here, we report the first maternally methylated DMR, CpG island 2 (CGI-2), is located(More)
Imprinted genes are expressed monoallelically depending on their parental origin, and play important roles in the regulation of fetal growth, development, and postnatal behavior. Most genes known to be imprinted have been identified and studied in the human and the mouse. However, there are only a small number of reported imprinted genes in pigs. Therefore,(More)
Ordered tetrad analysis is important content in the genetics teaching. In particular, the two linkage gene mapping is not only a key point, but also a difficult one. How to explain the content better is a hard nut for the many genetics teachers or editors of the teaching material to crack. Here, based on teaching practice of many years we summarized several(More)
