16. New Functions for Old Genes in the Mouse Placenta
Abstract : Different species are separated by pre-zygotic reproductive barriers which impede gene flow between them. Rarely, when pre-zygotic barriers break down, interspecific hybrids are produced that display abnormal phenotypes, collectively called hybrid dysgenesis effects. READ MORE

17. Epigenetic Regulation of Genomic Imprinting and Higher Order Chromatin Conformation
Abstract : The genetic information encoded by the DNA sequence, can be expressed in different ways. Genomic imprinting is an epigenetic phenomenon that results in monoallelic expression of imprinted genes in a parent of origin-dependent manner. Imprinted genes are frequently found in clusters and can share common regulatory elements. READ MORE

18. The Functional Significance and Chromatin Organisation of the Imprinting Control Regions of the H19 and Kcnq1 Genes
Abstract : Genomic imprinting is a phenomenon through which a subset of genes are epigenetically marked during gemtogenisis. This mark is maintained in the soma to often manifest parent of origin-specific monoalleleic expresson patterns. READ MORE

19. The Control of the Epigenome
Abstract : The genetic information required for the existence of a living cell of any kind is encoded in the sequence information scripted in the double helix DNA. A modern trend in biology struggles to come to grip with the amazing fact that there are so many different cell types in our body and that they are directed from the same genomic blueprint. READ MORE

20. Long-range Control of Gene Expression by Imprinting Control Regions During Development and Neoplasia
Abstract : Genomic imprinting is an epigenetic phenomenon by which a subset of genes is expressed in a parent of origin specific manner. Most of the imprinted genes are located in clusters. Genetic evidences suggest that genes in imprinted clusters are regulated by Imprinting Control Regions (ICRs). READ MORE
