1. BEN-solo proteins in genome architecture and function
Abstract : Eukaryotic genomes are organized in a complex manner inside the nucleus of each cell. Chromatin insulators are DNA elements that help to fold the linear DNA fiber in three-dimensional space and partition regulatory gene units. READ MORE

2. Chromatin Insulators and CTCF: Architects of Epigenetic States during Development
Abstract : A controlled and efficient coordination of gene expression is the key for normal development of an organism. In mammals, a subset of autosomal genes is expressed monoallelically depending on the sex of the transmitting parent, a phenomenon known as genomic imprinting. READ MORE

3. 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

4. Transcriptional and epigenetic control of gene expression in embryo development
Abstract : During cell specification, temporal and spatially restricted gene expression programs are set up, forming different cell types and ultimately a multicellular organism. In this thesis, we have studied the molecular mechanisms by which sequence specific transcription factors and coactivators regulate RNA polymerase II (Pol II) transcription to establish specific gene expression programs and what epigenetic patterns that follows.

5. 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.
