1. Transcriptional and epigenetic control of gene expression in embryo development
Sammanfattning : 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. LÄS MER
2. The interplay of transcription and chromatin regulation during embryonic development
Sammanfattning : A fascinating aspect of multicellular development is the production of diverse cell types from an identical DNA genome, which depends on the ability to express different complements of genes across space and time. This thesis tries to address how the genome, within the chromatin structure that envelops it, is regulated to direct this complex process. LÄS MER
3. BEN-solo proteins in genome architecture and function
Sammanfattning : 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. LÄS MER
4. Gene regulation during development by chromatin and the Super Elongation Complex
Sammanfattning : Developmental processes are carefully controlled at the level of transcription to ensure that the fertilized egg develops into an adult organism. The mechanisms that controls transcription of protein-coding genes ultimately ensure that the Pol II machine synthesizes mRNA from the correct set of genes in every cell type. LÄS MER
