1. 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
2. Histone modification regulated bysuppressor of Zeste 12 and Ipl1 : Aurora-like kinase in Drosophila
Sammanfattning : Polycomb group (PcG) proteins are a group of genome wide silencers that are crucial for many processes during the development. In Drosophila PcG proteins are organised into four different complexes: PRC1, PRC2, PhoRC and PR-DUB. PRC2 consists of four core proteins: Su(z)12, E(z), Esc and Nurf. LÄS MER
3. The Nucleosome as a Signal Carrying Unit : From Experimental Data to Combinatorial Models of Transcriptional Control
Sammanfattning : The human genome consists of over 3 billion nucleotides and would be around 2 meters long if uncoiled and laid out. Each human somatic cell contains all this in their nucleus which is only around 5 µm across. This extreme compaction is largely achieved by wrapping the DNA around a histone octamer, the nucleosome.

4. The Impact of Tryptase and Epigenetic Mechanisms on Mast Cells
Sammanfattning : Mast cells have a large influence on multiple immune-mediated responses, including allergic conditions, and they have been implicated in various diseases such as arthritis and cancer. Mastocytosis is characterized by abnormal mast cell proliferation induced by mutations in KIT, the stem cell factor (SCF) receptor. LÄS MER
5. Genetic and Epigenetic Characterisation of Breast Tumours
Sammanfattning : Breast tumours harbour a large amount of genetic and epigenetic alterations, which are associated with e.g. tumour aggressiveness, prognosis, and response to therapy. LÄS MER
