6. Climbing the Trichoptera Tree : Investigations of Branches and Leaves
Sammanfattning : The Trichoptera (caddisflies) is the largest of the primary aquatic insect orders, currently including more than 13,500 species. With more than 100 species new to science described annually, the known caddisfly diversity is rapidly increasing. In the first four papers of this Thesis, a total of 22 species new to science are described. LÄS MER
7. Genomic and transcriptomic sequencing in chronic lymphocytic leukemia
Sammanfattning : Identification of recurrent mutations through next-generation sequencing (NGS) has given us a deeper understanding of the molecular mechanisms involved in chronic lymphocytic leukemia (CLL) development and progression and provided novel means for risk assessment in this clinically heterogeneous disease. In paper I, we screened a population-based cohort of CLL patients (n=364) for TP53, NOTCH1, SF3B1, BIRC3 and MYD88 mutations using Sanger sequencing, and confirmed the negative prognostic impact of TP53, SF3B1 or NOTCH1 aberrations, though at lower frequencies compared to previous studies.

8. NMR studies of DNA/RNA-binding proteins
Sammanfattning : This thesis concerns the structure and internal dynamics inDNA and RNA-binding proteins. While it has long been known thata proper three-dimensional structure is essential for aprotein's ability to interact with other biomolecules, theinfluence of the inherent protein dynamics is less wellunderstood.

9. Pathogenic mechanisms affecting mitochondrial DNA replication and transcription
Sammanfattning : Mitochondria are cytoplasmic organelles fundamental to life and health. In mitochondria, energy from the food we eat is converted into adenosine triphosphate (ATP), which in turn is used as a source of chemical energy to drive a multitude of cellular reactions. LÄS MER
10. Silencing and DNA double-strand break repair in budding yeast
Sammanfattning : Transcriptional silencing that makes large chromosomal domains inaccessible for the transcriptional apparatus is nucleated at DNA elements called silencers. In K.lactis a 102bp HMLα silencer was defined revealing three distinct protein-binding regions (A, B, and C) that were required for silencing of HMLα. LÄS MER
