  1. 1. The Adenovirus L4-33K Protein : A Key Regulator of Virus-specific Alternative Splicing

    Author : Heidi Törmänen Persson; Göran Akusjärvi; Stefan Schwartz; Marie Öhman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; L4-33K; adenovirus; splicing; phosphorylation; localization; replication centers; L4-22K; MLTU; DNA-PK; DNA-dependent protein kinase; PKA; cAMP-dependent protein kinase; transcription sites; SR protein; Medical Virology; Medicinsk virologi;

    Abstract : Adenoviruses have been extensively studied in the field of gene regulation, since their genes are subjected to a tightly controlled temporal expression during the virus lifetime. The early-to-late shift in adenoviral gene expression distinguishes two completely different programs in gene expression. READ MORE

  2. 2. Cyclic Nucleotide Phosphodiesterase 3B: Regulation in rat adipocytes and 3T3-L1 cells

    Author : Tova Landström; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3T3-L1 TNF-alpha; adipocyte; insulin; p70S6 kinase; mitogen-activated protein kinase; protein kinase B; phosphatidylinositol-3 kinase; phosphodiesterase 3B; cAMP; lipolysis; phosphorylation; signal transduction; Biochemistry; Metabolism; Biokemi; metabolism;

    Abstract : Insulin stimulation of rat adipocytes results in phosphorylation and activation of the cyclic nucleotide phosphodiesterase 3B (PDE3B), a key enzyme in the antilipolytic signalling pathway of this hormone. In this thesis, the site phosphorylated in PDE3B upon stimulation of rat adipocytes with insulin and/or the beta-adrenergic agonist, isoproterenol is identified. READ MORE

  3. 3. Alpha-2 Adrenergic Receptors and Signal Transduction : Effector Output in Relation to G-Protein Coupling and Signalling Cross-Talk

    Author : Johnny Näsman; Peter Evans; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; Adrenergic; receptor; G-protein; adenylyl cyclase; cAMP; calcium; cross-talk; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : The alpha-2 adrenergic receptor (α2-AR) subfamily includes three different subtypes, α2A-, α2B- and α2C-AR, all believed to exert their function through heterotrimeric Gi/o-proteins. The present study was undertaken in order to investigate subtype differences in terms of cellular response and to explore other potential signalling pathways of α2-ARs. READ MORE

  4. 4. LKB1 signaling pathways in adipocytes - Focus on the AMPK-related kinase SIK2

    Author : Emma Henriksson; Proteinfosforylering; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adipocytes; signal transduction; protein phosphorylation; LKB1; SIK2; SIK3; cAMP;

    Abstract : Adipose tissue does not only store and release energy in response to hormones, it is also known as an endocrine organ, secreting important factors and hormones that influence for example appetite and insulin sensitivity. The association of type 2 diabetes with obesity has been known for quite some time. READ MORE

  5. 5. Cyclic nucleotide signalling systems in vascular smooth muscle cells and immune system cells with special reference to phosphodiesterases PDE3 and PDE4

    Author : Dag Ekholm; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HTLV-I; multiple sclerosis; proliferation; phosphorylation; T-lymphocytes; vascular smooth muscle; cloning; protein kinase A; cGMP; cAMP; PDE4; Phosphodiesterase; PDE3; cilostamide; rolipram; Histology; cytochemistry; histochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur;

    Abstract : The cyclic nucleotide signalling systems are important in vascular smooth muscle and in the immune system, and are of interest from a pharmacological point of view. Drugs which interfere with the cyclic nucleotide levels have profound effects on heart, blood vessels and airways and have actual or potential use in several important diseases, such as heart failure, hypertension, arteriosclerosis, asthma and autoimmune diseases.
