| Research Abstract |
I have previously identified Peg10 as a novel imprinted gene. Moreover, I have confirmed that Peg10 is a retrotransposon-derived gene and have an essential function for placental development. In this grant, to reveal the mechanism of Peg10 function in placenta, I have established Peg10 KO TS (Trophoblast Stem) cell lines from Peg10 KO mice. By comparing the gene expression between Peg10 KO TS cell lines and wild type TS cell lines, I could succeed in the isolation of Peg10 down regulated genes. These genes must be important for the evolution of mammalian viviparity.
