Roles of Protein Factors in Regulation of Imprinted Gene Expression Abstract Genomic imprinting is an important epigenetic phenomenon in which only one parental allele is expressed. Allele-specific DNA methylation often exists in imprinted control regions (ICRs) and is required for properly imprinted expression. Imprinting control in mammals involves an insulator mechanism that requires CTCF or a long ncRNA silencing mechanism. In this dissertation, I studied functions of protein factors in genomic imprinting. First, methylated DNA binding proteins are involved in maintenance of DNA methylation at imprinted loci and required for selective silencing of one specific allele. eW showed that MBD3 was localized to paternal H19 ICR. By RNA interference experiments in preimplantation embryos, we showed that MBD3 and its NuRD complex cofactor MTA2 were required for maintenance of the paternal methylation at the H19 ICR, and for silencing of the paternal H19. MTA2 is also required for Peg3 allelic expression. These results demonstrate new roles of the NuRD complex in genomic imprinting. Moreover, I showed allele-specific associations of MBD1 and Kaiso with imprinted loci, implicating functional requirements of these proteins in imprinted regulation. -

Administration of Barack Obama, 2011 Remarks on Presenting The
Administration of Barack Obama, 2011 Remarks on Presenting the National Medal of Science and the National Medal of Technology and Innovation October 21, 2011 Welcome, everybody. Please have a seat. It is a great pleasure to be with so many outstanding innovators and inventors. And I'm glad we could convince them all to take a day off—[laughter]—to accept our Nation's highest honor when it comes to inventions and innovation, and that is the National Medals of Science and the National Medals of Technology and Innovation. It's safe to say that this is a group that makes all of us really embarrassed about our old science projects. [Laughter] You know, the volcano with the stuff coming out—[laughter]— with the baking soda inside. Apparently, that was not a cutting-edge achievement— [laughter]—even though our parents told us it was really terrific. But thanks to the men and women on the stage, we are one step closer to curing diseases like cancer and Parkinson's. Because of their work, soldiers can see the enemy at night and grandparents can see the pictures of their grandchildren instantly and constantly. Planes are safer, satellites are cheaper, and our energy grid is more efficient, thanks to the breakthroughs that they have made. And even though these folks have not sought out the kind of celebrity that lands you on the cover of People magazine, the truth is that today's honorees have made a bigger difference in our lives than most of us will ever realize. When we fill up our cars, talk on our cell phones, or take a lifesaving drug, we don't always think about the ideas and the effort that made it all possible. -
