  1. 1. Regulation and transport mechanisms of eukaryotic aquaporins

    Författare :Madelene Palmgren; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aquaporin; Membrane protein; Transport; Glycerol; Aquaglyceroporins; Regulation; arsenite;

    Sammanfattning : Aquaporins are found in all kingdoms of life where they are involved in water homeostasis. They are small transmembrane water conducting channels that belong to the ancient protein family Major Intrinsic Proteins (MIP). LÄS MER

  3. 2. Prokaryotic Arsenic Resistance - Studies in Bacillus subtilis

    Författare :Emil Aaltonen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ArsB; Bacillus subtilis; arsenic resistance; arsenate reduction; arsenite transport; gene regulation; arsenate; ArsR; arsenite; transmembrane topology; Acr3; ArsK;

    Sammanfattning : Arsenic is a toxic metalloid which is found all over the globe. Due to its toxicity and wide abundance, all living organisms have evolved intrinsic arsenic resistance systems. In this study, three proteins that provide arsenic resistance in the Gram-positive bacterium Bacillus subtilis have been investigated. LÄS MER

  4. 3. Stress, Homeostasis and Robustness: Molecular and Systems Level Analysis in Yeast

    Författare :Doryaneh Ahmadpour; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Abstract Cells constantly encounter stress due to alterations in the external milieu or internal parameters. However, cells are robust to such changes and maintain homeostasis. Using the yeast Saccharomyces cerevisiae as a model organism, we attempted to elucidate aspects of homeostasis and robustness at both molecular and systems levels. LÄS MER
