1. Regulators of chromatin and transcription in Drosophila
Sammanfattning : Development of multicellular organisms is achieved by organized temporal and spatial patterns of gene expression leading to cell differentiation. Chromatin regulators control how the DNA is utilized by altering access of proteins to DNA and thereby function as co-factors in transcription. LÄS MER
2. Regulation of gene expression in fruit flies : how does it start, and will it be remembered?
Sammanfattning : One of the most distinctive features of eukaryotic chromosomes is the bundling of DNA together with functionally associated RNA and proteins in chromatin. This allows huge amounts of DNA to be packed inside the very tiny space of the nucleus, and alterations in the structure of chromatin enable access to the DNA for transcription (“reading” genes by production of RNA copies).

3. 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.

4. 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
5. Oxygen-dependent regulation of transcription by the hypoxia-inducible factor-1
Sammanfattning : Under limited oxygen availability (hypoxia) cells undergo rapid reprogramming in order to survive in the new environment until normoxic conditions are re-established. The observation that hypoxia can induce the expression of genes involved in erythropoiesis, angiogenesis and glucose metabolism among others, led to the identification of the hypoxia-inducible factor-1 (HIF-1) as a master regulator of the hypoxia-response pathway.
