21. The deep evolutionary roots of non-coding RNA - a comparative genomics approach
Sammanfattning : Non-coding RNAs (ncRNA) are a diverse group of genes that do not encode proteins but function exclusively on the level of RNA and were originally suggested to be remnants of a pre-DNA stage of life known as the RNA world. More recent work, however, has uncovered a rich repertoire of previously unknown families with possible consequences for our understanding of the origin and evolution of the modern RNA infrastructure.

22. Regulatory roles of two small RNAs in the human pathogen Listeria monocytogenes and the evaluation of an alternative infection model
Sammanfattning : Listeriosis is a potentially lethal disease caused by the Gram-positive facultative intracellular pathogen Listeria monocytogenes (L.m.). L. LÄS MER
23. Small non-coding RNA in early fly development : plasticity, interactions and improved bioinformatic tools
Sammanfattning : At fertilization, the male and female pronuclei undergo a transformation from germline to pluripotency as they fuse, marking the beginning of Drosophila embryogenesis. As the parental contributions decrease, the zygote takes control of its genome in a process called the maternal-to-zygotic transition (MZT). LÄS MER
24. Small non-coding RNAs in cancer
Sammanfattning : The complex genetics of cancer, which allows tumours to grow and spread while bypassing the control circuitry of the cell, involves dysregulation of the genome, transcriptome and proteome. The importance of protein-coding genes such as growth factors and hormone receptors is well established. LÄS MER
25. Biology of a small RNA virus that infects Drosophila melanogaster
Sammanfattning : Drosophila melanogaster has been extensively used as a model organism to study diverse facets of biology, including host-pathogen interactions and the basic biology of its pathogens. I have used the fruit fly as a model to study elementary aspects of Nora virus biology, such as the role of the different proteins encoded by the virus genome. LÄS MER
