1. 1. Gene Expression in Cancer Cells : Detection of Splice Variants, Allele-specific Expression and DNA Methylation

   Författare :Lili Milani; Ann-Christine Syvänen; Thomas R. Gingeras; Uppsala universitet; []
   Nyckelord :;

   Sammanfattning : The human genome sequencing project has provided a wealth of information on sequence variation between individuals. The surprisingly low number of genes in the human genome is compensated for by a complex regulation of gene expression. LÄS MER

3. 2. Population genomic analyses of regulatory variation and selection in Brassicaceae species

   Författare :Robert Horvath; Tanja Slotte; Peter Hambäck; Douglas G. Scofield; Matthew Webster; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Capsella grandiflora; Arabidopsis thaliana; Arabidopsis lyrata; natural selection; gene expression variation; DNA and gene body methylation; transposable elements; DNA accessibility; gene expression noise; epigenetic silencing; linked selection; ekologi och evolution; Ecology and Evolution;

   Sammanfattning : The impact of selection on regulatory variation and the contribution of regulatory changes to phenotypic variation has long been debated in evolutionary genetics. Because cis-regulatory elements such as promoters and enhancers can be difficult to identify, it has been more challenging to quantify the impact of selection on variation in cis-regulatory regions than in protein-coding regions.

4. 3. Sexual Conflict and Gene Expression in Drosophila melanogaster

   Författare :Paolo Innocenti; Edward Morrow; Göran Arnqvist; Andrew G Clark; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sexual conflict; sexual selection; male-female coevolution; gene expression; transcriptome; microarrays; sexual dimorphism; Drosophila; Biology; Biologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : Sexual conflict is broadly defined as a conflict between the evolutionary interests of the two sexes. Depending on the genetic architecture of the traits involved, it can occur at the level of male-female interactions or take the form of selection acting to change the mean of a shared trait against the sign of its genetic correlation.

5. 4. MHC diversity and expression in a songbird : Temporal and transgenerational variation

   Författare :Samantha Mellinger; MEMEG; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MHC diversity; MHC-I gene expression; songbirds; genome assembly; amplicon HTS; temporal variation; family data; great reed warbler Acrocephalus arundinaceus ;

   Sammanfattning : The immune system is of central importance to clear-off pathogens in order to keep an organism healthy. In vertebrates, the Major Histocompatibility Complex (MHC) is a genomic region that holds key genes involved in adaptive immunity and in particular in the antigen presenting process. LÄS MER

7. 5. Intrinsic disorder and tandem repeats - match made in evolution : Computational studies of molecular evolution

   Författare :Oxana Lundström; Arne Elofsson; Liberles-Siltberg Jessica; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein evolution; intrinsically disordered proteins IDPs ; tandem repeats; short tandem repeats STRs ; genetic variation; orphan proteins; GC content; human STR variation; colorectal cancer; gene expression; biokemi med inriktning mot bioinformatik; Biochemistry towards Bioinformatics;

   Sammanfattning : Proteins are both the building blocks and workers of the cell, carrying out most of the important functions. For a long time, their structure has been regarded as the primary factor for their function, but intrinsically disordered proteins demonstrate an alternative to this paradigm. LÄS MER
