1. Importance of the Clr2 protein in heterochromatin formation in the fission yeast Schizosaccharomyces pombe
Sammanfattning : Epigenetics is an area of biology that studies heritable changes in gene ex- pression without any change in the DNA sequence. The most studied epige- netic mechanisms are DNA methylation, RNA interference and histone mod- ifications. LÄS MER
2. Chromatin Dynamics in the Fission Yeast, Schizosaccharomyces pombe
Sammanfattning : In the eukaryotic cell nucleus, spatial organization and dynamics of the genome is important in the regulation of gene expression. This thesis describes the use of the fission yeast, Schizosaccharomyces pombe, to study chromatin regulation and dynamics. We used nitrogen starvation to induce transcription of genes in fission yeast cells. LÄS MER
3. Post-transcriptional regulation after stress in Schizosaccharomyces pombe
Sammanfattning : Post transcriptional regulation is part of the gene expression control and is important for many cellular processes. It influences how mRNAs are selected for translation, degradation or storage. In this thesis, I describe some of the known mechanisms for transcriptional regulation in S. LÄS MER
4. Characterization of Gcn5 histone acetyltransferase in Schizosaccharomyces pombe
Sammanfattning : The organisation of eukaryotic DNA into chromatin provides a natural barrier that prevents full access to the DNA thereby inhibiting events such as transcription, replication and repair. In order for these DNA-related events to occur, the chromatin needs to be modified by chromatin remodelling or, by reversible post-translational modifications. LÄS MER
5. Studies of histone modification systems in Schizosaccharomyces pombe
Sammanfattning : The genetic information in every cell is carried in the DNA. In eukaryotes the DNA is wrapped twice around proteins called histones forming a repeating unit called the nucleosome, in fibers known as chromatin. Nucleosomes are folded into higher order structures forming the chromosomes. LÄS MER
