  1. 1. Physiology of Saccharomyces cerevisiae Producing Recombinant Insulin in Continuous Culture

    Författare :Ali Kazemi Seresht; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unfolded protein response; Keywords: heterologous protein production; prolonged chemostat; transcriptome; insulin analogue precursor; metabolic adaptation; URA3d; plasmid copy number; promoter truncation; high cell density cultivation; TPI1;

    Sammanfattning : The yeast Saccharomyces cerevisiae has widely been used as a host for the production of heterologous proteins. High-level production of heterologous proteins is likely to impose a metabolic burden on the host cell and can thus affect various aspects of cellular physiology. LÄS MER

  3. 2. Genetic and epigenetic alterations in melanoma

    Författare :Rainer Tuominen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Malignant melanoma is a disease that may arise in several different parts of the body, preferentially the skin, rarely in the mucosal membranes or the choroidal tissues of the eye. The incidence of cutaneous melanoma (CMM) is steadily increasing in the Caucasian populations, unlike uveal melanoma (UM) that shows a stable incidence. LÄS MER

  4. 3. Studies on growth hormone induced female-characteristic gene transcription in rat liver

    Författare :Cissi Gardmo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Growth hormone; liver; gene expression; sex differentiation; in vivo transfection; primary hepatocytes;

    Sammanfattning : Growth hormone (GH) secretion is sexually dimorphic, which has an impact on hepatic gene expression. This is particularly pronounced in rats but has also been demonstrated in other species, including humans. LÄS MER

  5. 4. Pharmacogenetics of human cytochrome P450 3A (CYP3A) enzymes

    Författare :Anna Westlind Johnsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The cytochrome P450 3A (CYP3A) subfamily encompasses the most important CYP enzymes with respect to drug metabolism, in particular CYP3A4. responsible for the metabolism of a majority of drugs being metabolized in order to be excreted. LÄS MER
