  2. 1. The Multifunctional HnRNP A1 Protein in the Regulation of the Cyp2a5 Gene : Connecting Transcriptional and Posttranscriptional Processes

    Author : Tina Glisovic; Matti Lang; Francoise Raffalli-Mathieu; Lorenz Poellinger; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biochemistry; Cyp2a5; DNA-protein interaction; gene regulation; hnRNP A1; nucleocytoplasmic shuttling; RNA-protein interaction; RNA stabilization; posttranscriptional; transcriptional; Farmaceutisk biokemi; Pharmaceutical biochemistry; Farmaceutisk biokemi;

    Abstract : The mouse xenobiotic-inducible Cyp2a5 gene is both transcriptionally and posttranscriptionally regulated. One of the most potent Cyp2a5 inducers, the hepatotoxin pyrazole, increases the CYP2A5 mRNA half-life. READ MORE

    Abstract : Aquatic organisms are constantly at risk of being exposed to potentially harmful chemical compounds of natural or anthropogenic origin. Biological life can for instance respond to chemical stressors by changes in gene expression, and thus, certain gene transcripts can potentially function as biomarkers, i.e. READ MORE

  5. 3. Bactericidal/Permeability-Increasing Protein (BPI) and Proteinase 3: Studies at the Transcriptional Level

    Abstract : In myelopoiesis, neutrophils and monocytes/macrophages are formed from a common myeloid precursor cell in the bone marow. During maturation of neutrophils, cytoplasmic granules are formed in the cells and the content of these granules is critical for the function of neutrophils in the first line of defense against invading microorganisms.

    Abstract : Parkinson’s Disease (PD) is the most common movement disorder and second most common neurodegenerative disease. The principal hallmark of the pathology is represented by a loss of mesencephalic Dopaminergic neurons (mesDA) that reside in the Substantia Nigra pars compacta (SNpc). READ MORE

  7. 5. Genome-wide Studies of Transcriptional Regulation in Yeast

    Author : Jakub Orzechowski Westholm; Jan Komorowski; Anthony Wright; Uppsala universitet; []

    Abstract : In this thesis, nutrient signalling in yeast is used as a model to study several features of gene regulation, such as combinatorial gene regulation, the role of motif context and chromatin modifications. The nutrient signalling system in yeast consists of several pathways that transmit signals about the availability of key nutrients, and regulate the transcription of a large part of the genome.
