1. 1. Complex Trait Genetics : Beyond Additivity

   Författare :Simon Forsberg; Örjan Carlborg; Julien Ayroles; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; genetic interactions; epistasis; additivity; GWAS; vGWAS; Genetic mapping; yeast; Arabidopsis Thaliana; dog; Genetik; Genetics;

   Sammanfattning : The link between the genotype and the phenotype of an organism is immensely complex. Despite this it can, to a great extent, be captured using models that assume that gene variants combine their effects in an additive manner. This thesis explores aspects of genetics that cannot be fully captured using such additive models. LÄS MER

3. 2. Factors modulating tRNA biogenesis and function in Saccharomyces cerevisiae

   Författare :Fu Xu; Anders Byström; Marcus J. O. Johansson; Raffael Schaffrath; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Translation; tRNA biogenesis; suppressor tRNA; Elongator complex; wobble uridine modifications; SUP4; YPK9; SSD1; serine tRNA; synthetic lethality; yeast; biology; biologi; molekylärbiologi; Molecular Biology; Genetics; genetik;

   Sammanfattning : Transfer RNA (tRNA) genes are transcribed by RNA polymerase III as precursors that undergo multiple processing steps to form mature tRNAs. These steps include processing of the 5’ leader and 3’ trailer sequences, addition of a 3’ CCA tail, removal of introns, and formation of modified nucleosides. LÄS MER

4. 3. Functional organisation of the cell nucleus in the fission yeast, Schizosaccharomyces pombe

   Författare :Jenny Alfredsson Timmins; Pernilla Bjerling; Wendy Bickmore; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fission yeast; heterochromatin; subnuclear organisation; chromo domain proteins; boundary elements; transcriptional regulation; epigenetics; Molecular biology; Molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; Genetics; Genetik; Molecular Biology; molekylärbiologi; Genetics; genetik;

   Sammanfattning : In eukaryotes the genome adopts a non-random spatial organisation, which is important for gene regulation. However, very little is known about the driving forces behind nuclear organisation. LÄS MER

5. 4. Studies of Budding Yeast Transcription Factors Acting Downstream of Nutrient Signaling Pathways

   Författare :Niklas Nordberg; Hans Ronne; Anders Blomberg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budding yeast; nutrient signaling; glucose repression; aging; caloric restriction; JmjC; histone demethylation; Mig1; Mig2; Mig3; Gis1; Rph1; Molekylär genetik; Molecular Genetics;

   Sammanfattning : Being able to respond to extracellular cues such as nutrients and growth factors is of vital importance to all living cells. Pathways have therefore evolved which can sense the extracellular status, transmit a signal through the cell and affect gene expression, which ultimately enables adaptation. LÄS MER

7. 5. Systems Biology of Yeast Lipid Metabolism

   Författare :Pramote Chumnanpuen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Transcriptome; Integrated analysis; Lipidome.; Inositol-choline; Opi1; Yeast lipid metabolism; high throughput techniques; Ino4; TORC1; Snf1; Ino2;

   Sammanfattning : Lipid metabolism plays an important role in the development of many different life-style related diseases, such as type 2 diabetes and atherosclerosis, and understanding the molecular mechanisms behind regulation of lipid biosynthesis and degradation may lead to development of new therapies. In this project we undertook a global study of lipid metabolism in the eukaryotic model organism Saccharomyces cerevisiae. LÄS MER
