1. Epigenetic Control of Mammalian Development : Studies on an imprinting control region
Abstract : A subset of autosomal genes is preferentially or exclusively expressed from one of the parental alleles. This phenomenon, termed genomic imprinting, is highlighted by the neighboring Igf2 and H19 genes, which are monoallelically expressed on opposite parental chromosomes. These features are governed by a 2. READ MORE

2. 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

3. 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

4. Genomic Imprinting in Development and Evolution
Abstract : Genetic information is encoded by the linear sequence of the DNA double helix, while epigenetic information is overlayed as the packaging of DNA and associated proteins into the chromatin structure. Variations in chromatin structure play a vital role in establishing and maintaining patterns of gene expression during differentiation and development of higher eukaryotes, and disruption of this epigenetic gene regulation can lead to cancer.

5. Long Noncoding RNA Mediated Regulation of Imprinted Genes
Abstract : Genomic imprinting is an epigenetic phenomenon that causes a subset of mammalian genes to be expressed from only one allele in a parent-of-origin manner. The defects in the imprinting regulation result in disorders that affect development, growth and metabolism. READ MORE
