  2. 1. Thioredoxins and gene regulation in the Drosophila germline

    Author : Malin J. Svensson; Jan Larsson; David Roberts; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drosophila; thioredoxin; sex-specific; Pof; chromosome 4; gene regulation; kromosom 4; genreglering; Drosophila; thioredoxin; könsspecifik; Pof; Molecular biology; Molekylärbiologi;

    Abstract : Spermatogenesen är i många organismer en av de mest dramatiska förvandlingar som en cell kan genomgå – en vanlig, rund, diploid cell omvandlas till en nålformad, haploid cell med ett tätt packat cellmaskineri. I bananfluga, Drosophila melanogaster, innebär denna process flera karaktäristiska stadier. READ MORE

  4. 2. Sexual conflict, sexual selection, and genetic variance in fitness

    Author : Karl Grieshop; Göran Arnqvist; David Berger; Jacek Radwan; Uppsala universitet; []
    Keywords : Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : Understanding sex-specific genetic variance for fitness is of fundamental importance to our understanding of evolution. This thesis presents the findings of empirical investigations into sex-specific genetic variance in fitness. READ MORE

  5. 3. Sex Chromosome Evolution in a Hermaphrodite : Genetic and phenotypic relationships between sex roles

    Author : Anna Nordén; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sex chromosome evolution; Hermaphrodite; Inter-sexual genetic correlation; Quantitative genetics; Macrostomum lignano; Experimental evolution; Sexual conflict;

    Abstract : Sex chromosome evolution in a hermaphrodite ancestor starts with the establishment of a sex-determining region (SDR). Over time, sex-specific genes, and/or sexually antagonistic alleles will become linked to the SDR. READ MORE

  6. 4. The role of CysLT1R in animal models of colorectal cancer

    Author : Sayeh Savari; Malmö Cellpatologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Cysteinyl leukotrienes (LTC4, LTD4 and LTE4) are potent pro-inflammatory lipids derived from arachidonic acid and mediate their effect through CysLT1R and CysLT2R. There is a strong correlation between long-standing inflammatory bowel disease where these pro-inflammatory mediators are abundant and colorectal cancer. READ MORE

  7. 5. Metapopulations dynamics and sex-specific resource allocation in Silene dioica

    Author : Elisabet Peedu; Pär Ingvarsson; Barbara Giles; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Silene dioica; Skeppvik Archipelago; Metapopulation Dynamics; Population Genetic Structuring; Genetic Diversity; Gene Flow; Sex-Specific Resource Allocation; Cost of Reproduction; Life-History Theory; Sexual Dimorphism; Reproductive Effort; biology; biologi; evolutionär genetik; evolutionary genetics; ekologisk botanik; Ecological Botany;

    Abstract : Rising archipelagos provide unique settings for the study of the temporal and spatial dynamics of their biota. This offers the possibility to study the ecology and genetics of early successional processes; both between islands that differ in age and within islands when already established organisms have to keep pace with the changing environment.
