  1. 1. Cis-regulatory variation and divergence in Capsella

    Författare :Kim A. Steige; Tanja Slotte; Jeff J. Doyle; Uppsala universitet; []
    Nyckelord :Capsella; Shepherd s Purse; cis-regulatory changes; allele-specific expression; mating system shift; floral evolution; polyploidy; positive selection; purifying selection; transposable elements; small RNA; methylation; transposable element silencing; distribution of fitness effects;

    Sammanfattning : Cis-regulatory changes in e.g. promoters or enhancers that affect the expression of a linked focal gene have long been thought to be important for adaptation. In this thesis, I investigate the selective importance and genomic correlates of cis-regulatory variation and divergence in the genus Capsella, using massively parallel sequencing data. LÄS MER

  3. 2. In silico prediction of CIS-regulatory elements

    Författare :Albin Sandelin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Transcriptional regulation; transcription factor binding sites; phylogenetic footprinting; pattern finding; pattern comparison;

    Sammanfattning : As one of the most fundamental processes for all life forms, transcriptional regulation remains an intriguing and challenging subject for biomedical research. Experimental efforts towards understanding the regulation of genes is laborious and expensive, but can be substantially accelerated with the use of computational predictions. LÄS MER

  4. 3. Transposable Elements in Neural Progenitor Cells

    Författare :Liana Fasching; Molekylär neurogenetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transposable Elements; TRIM28; Epigenetic Regulation; Gene Expression; Neural Progenitor Cells;

    Sammanfattning : More than 90% of DNA does not code for proteins and for a long time these sequences were referred to as “junk DNA” due to their unknown purpose. With the advent of new technologies it is now known, that the non-coding part of the genome is of great importance for regulating gene expression and is therefore indispensable. LÄS MER

  5. 4. Population Genetics of Human Genomic Elements

    Författare :Thijessen Naidoo; Mattias Jakobsson; Guillaume Achaz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; population genetics; human genome; functional elements; natural selection; pseudogenes; loss-of-function; gene regulation; Y chromosome; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Sammanfattning : The genomes of living organisms are composed of a multitude of functional units, which interact with each other and their environment in a highly regulated fashion, to facilitate the expression of an enduring (and evolving) phenotype. Several approaches have emerged in the effort to identify these functional units and explore their activities. LÄS MER

  7. 5. Computational and experimental approaches to regulatory genetic variation

    Författare :Malin Andersen; Jacob Odeberg; John Peden; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular biology; Genetics; single nucleotide polymprhism SNP ; regulatory SNP; transcription factor binding site; phylogenetic footprinting; allelic imbalance; EMSA; CD36; cardiovascular disease.; Genetic engineering including functional genomics; Genteknik inkl. funktionsgenomik;

    Sammanfattning : Genetic variation is a strong risk factor for many human diseases, including diabetes, cancer, cardiovascular disease, depression, autoimmunity and asthma. Most of the disease genes identified so far alter the amino acid sequences of encoded proteins. LÄS MER
