  1. 1. Acrylamide in Potato Crisps - A Three-year Study on Swedish-grown Potatoes

    Författare :Gunilla Viklund; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Potato varieties; Asparagine; Acrylamide; Potato crisps; Reducing sugars;

    Sammanfattning : Acrylamide, a probable human carcinogen, has been found at mg/kg levels, in heat-treated carbohydrate-rich foods. Acrylamide is formed via the Maillard reaction as a result of the reaction between the amino acid asparagine and reducing sugars (glucose and fructose). LÄS MER

  3. 2. Acrylamide in food products : Identification, formation and analytical methodology

    Författare :Sune Eriksson; Margareta Törnqvist; Leif Kronberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acrylamide; food; analytical methods; measurements in air; Environmental chemistry; Miljökemi;

    Sammanfattning : The aim of this thesis was to verify the indicated occurrence of acrylamide formation in heating of food, to identify factors affecting the formation, and to identify important sources of acrylamide exposure from food. As a prerequisite for the studies, gas- and liquid-chromatographic methods with mass spectrometric detection were developed for the analysis of acrylamide in food. LÄS MER

  4. 3. mRNA degradation factors as regulators of the gene expression in Saccharomyces cerevisiae

    Författare :Mridula Muppavarapu; Tracy Nissan; Per Sunnerhagen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mRNA decapping; mRNA degradation; Pat1; Edc3; Lsm4; Lsm1-7; P bodies; Dcp2; Transcription; Ribosome biogenesis; Exosome.; molekylärbiologi; Molecular Biology;

    Sammanfattning : Messenger RNA degradation is crucial for the regulation of eukaryotic gene expression. It not only modulates the basal mRNA levels but also functions as a quality control system, thereby controlling the availability of mRNA for protein synthesis. LÄS MER

  5. 4. Identification of novel pathways of regulation of AHR and HIF-­1 function

    Författare :Michael Gralla; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mammalian bHLH-Pas (basic HLH (helix-loop-helix)-PER-ARNT-SIM) proteins belong to the bHLH superfamily of transcription factors. Members of the family have a broad spectrum of functions that among others sense and regulate the cellular response to physiological signals such as low oxygen levels (hypoxia), or environmental signals such as toxins.

  7. 5. Mechanisms of cancer cell death by mutant p53-reactivating compound APR-246

    Författare :Sophia Ceder; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tumor suppressor TP53 is the most frequently mutated gene in cancer. A majority of TP53 mutations result in a mutant p53 that disrupts its DNA binding capabilities but may also acquire novel gain-of-function activities that contribute to tumor growth. LÄS MER
