  2. 1. Myc-induced Lymphomagenesis : In vivo assessment of downstream pathways

    Author : Sara Rimpi; Jonas Nilsson; Juha Klefström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Myc; lymphomagenesis; Aurora kinases; polyamine; glycolysis; targeting; mouse models of cancer; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Myc oncogenes encode transcription factors that bind to E-box sequences in DNA, driving the expression of a large number of target genes and are deregulated in approximately 70% of human cancers. Deregulated Myc expression cause enhanced proliferation (which is counteracted by apoptosis), angiogenesis and cancer. READ MORE

  4. 2. Lipid peroxidation in vivo : Evaluation and application of methods for measurement

    Author : Eva Södergren; Uppsala universitet; []
    Keywords : Medical sciences; lipid peroxidation; hydroperoxides; F2-isoprostanes; MDA; prostaglandins; measurement; carbon tetrachloride; vitamin E; dietary fat quality; rapeseed oil; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Geriatrics; geriatrik;

    Abstract : Lipid peroxidation is thought to be an important factor in the pathophysiology of a number of diseases and in the process of ageing, but its measurement in vivo has been difficult. The aim of this thesis was to evaluate methods for measurement of lipid peroxidation in vivo that are suitable for clinical investigations, and to apply these methods in animal and human studies investigating basal conditions and situations associated with increased lipid peroxidation.

  5. 3. Lead(II) as a Tool for Probing RNA Structure in vivo

    Author : Magnus Lindell; Gerhart Wagner; Roland Hartmann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; lead II cleavage; RNA structure; in vivo probing; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Abstract : Chemical modification and limited enzymatic hydrolysis are powerful methods to obtain detailed information on the structure and dynamics of RNAs in solution. In the work presented here I have taken advantage of the properties of the divalent metal ion lead(II) to establish it as a new probe for investigating the structure of RNA in vivo. READ MORE

  7. 5. Up-regulation of dopamine D₂ receptors : in vitro and in vivo studies

    Author : Maria Wanderoy; Eliassitet Eriksson; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurochemistry; Neurokemi; neurokemi och neurotoxikologi; Neurochemistry and Neurotoxicology;

    Abstract : In the central nervous system (CNS) dopaminergic and dopaminoceptive neurons have the ability to respond to variations in dopamine levels by for example adjusting their dopamine receptor levels. One of the most well known phenomena in this respect is that long-term blockade of D2 receptors with antipsychotic drugs leads to an increase in striatal D2 receptor density of experimental animals as well as of schizophrenic patients as measured in both post-mortem studies and in vivo positron emission tomography studies of brain.
