  1. 1. Regulation of gene expression in fruit flies : how does it start, and will it be remembered?

    Författare :Aman Zare; Per Stenberg; Yuri B. Schwartz; Åsa Rasmuson-Lestander; Guillaume Filion; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila; epigenetics; transcription; gene regulation; transcription maintenance; CBP; polymerase pausing; Polycomb group proteins; transgenerational inheritance of transcriptional response; gut microbiome; molekylärbiologi; Molecular Biology;

    Sammanfattning : One of the most distinctive features of eukaryotic chromosomes is the bundling of DNA together with functionally associated RNA and proteins in chromatin. This allows huge amounts of DNA to be packed inside the very tiny space of the nucleus, and alterations in the structure of chromatin enable access to the DNA for transcription (“reading” genes by production of RNA copies).

    Sammanfattning : This thesis is a contribution to feminist laboratory studies and a critical engagement with the natural sciences, or more precisely research on the biochemical workings and deadly relations of Alzheimer’s disease emanating from a year of field work in a Drosophila fly lab. The natural sciences have been a point of fascination within the field of gender studies for decades. LÄS MER

  4. 3. Characterization of Novel Solute Carriers in Humans, Mice and Flies : Solute Carriers in a Broad and Narrow Perspective

    Författare :Mikaela Ceder; Robert Fredriksson; Anita Öst; Uppsala universitet; []

    Sammanfattning : The solute carrier family is the largest family of membrane-bound transporters in humans, with 430 members divided into 65 subfamilies. They transport various substrates across lipid barriers and are vital for absorption, distribution, metabolism and excretion in all cell types in the body. LÄS MER

  5. 4. Data in, lures out: designing selective lures against fruit pests

    Författare :Sebastian Larsson Herrera; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : With the push for rebuilding ecosystem resilience and the aim to lower the footprint of agriculture, there is an urgent need for novel, sustainable tools for managing pests. Insect olfaction is a good target to designing such novel tools. However, the rate at which odor-based insect control innovations are churned out is underwhelming. LÄS MER

  7. 5. Sexual conflict and male-female coevolution in the fruit fly

    Författare :Urban Friberg; Göran Arnqvist; Daniel Promislow; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cryptic male mate choice; Drosophila melanogaster; female mate choice; multiple mating; sexual conflict; sexually antagonistic coevolution; sexual selection; speciation; sperm competition; Biology; Biologi;

    Sammanfattning : Harmony and cooperation was for long believed to dominate sexual interactions. This view slowly started to change 25 years ago and is today replaced with a view where males and females act based on what is best from a costs-benefits perspective. LÄS MER
