1. On aging and the role of Ubp3 in heterochromatic gene silencing and protein quality control
Sammanfattning : Aging is characterized by a build-up of damage in organisms ranging from protists to multi-cellular species. This damage adversely affects core components such as DNA and proteins which are necessary to sustain life. LÄS MER
2. Non-protein-coding RNA : Transcription and regulation of ribosomal RNA
Sammanfattning : Cell growth and proliferation are processes in the cell that must be tightly regulated. Transcription of ribosomal RNA and ribosomal biogenesis are directly linked to cell growth and proliferation, since the ribosomal RNA encodes for the majority of transcription in a cell and ribosomal biogenesis influences directly the number of proteins that are synthesized.

3. Chromatin remodelling of ribosomal genes - be bewitched by B-WICH
Sammanfattning : Transcription of the ribosomal genes accounts for the majority of transcription in the cell due to the constant high demand for ribosomes. The number of proteins synthesized correlates with an effective ribosomal biogenesis, which is regulated by cell growth and proliferation. LÄS MER
4. Inferring evolution in bacteria using Markov chains and genomic signatures
Sammanfattning : This thesis concerns the development of methods and models in evolutionary molecular biology. The techniques are also applicable to other similar biological problems. The first contribution is a novel classifier using fixed and variable length Markov chains that can discriminate between bacterial DNA of different species. LÄS MER
5. Transcriptional regulation of ribosomal RNA gene : actin, myosin and beyond
Sammanfattning : In the eukaryotic cell nucleus, actin and nuclear myosin 1c (NM1) are key regulators of RNA polymerase I (Pol I) transcription and function across the entire ribosomal RNA biogenesis pathway. At the gene level, actin interacts with Pol I and together with NM1 they have been suggested to facilitate assembly of Pol I at the gene promoter. LÄS MER
