  1. 1. Receptors for growth hormone and prolactin. Regulation and activation

    Författare :Gunnel Hellgren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; GH receptor; Janus kinase; GH sensitivity; 5 -untranslated region; prolactin; prolactin receptor adipose tissue; liver; skeletal muscle; epidermal growth factor receptor; tyrosine kinase; kinase activity;

    Sammanfattning : Cytokine receptor activation is dependent on ligand-induced receptor dimerization or oligomerization and subsequent activation of several intracellular proteins. Activation of Janus kinases (Jaks) is probably the first intracellular event that occurs after receptor dimerization. LÄS MER

  3. 2. The growth hormone receptor and growth hormone sensitivity in man

    Författare :Ruth Wickelgren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; GH sensitivity; GH receptor; quantitative RT-PCR; IGF-I; skeletal muscle; adipose tissue; tissue-specific; promoter; 5´-untranslated region; psoriasis; epidermis;

    Sammanfattning : It is well established that the response to endogenous and exogenous growth hormone (GH) varies between individuals. For example, conditions with increased catabolic rate, such as trauma, sepsis and surgery, are believed to be associated with acquired GH insensitivity. LÄS MER

  4. 3. Regulation of the Expression of Mouse Ribonucleotide Reductase Small Subunit at the Levels of Transcription and Protein Degradation

    Författare :Anna Lena Chabes; Lars Thelander; Ylva Engström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; ribonucleotide reductase; transcription; protein degradation; cell cycle; Molekylärbiologi; Molecular biology; Molekylärbiologi; Medical Cell Biology; medicinsk cellbiologi;

    Sammanfattning : Deoxyribonucleic acid (DNA) carries all the genetic information of a cell. Ribonucleotide reductase (RNR) provides balanced pools of all four dNTPs, the building blocks of DNA. These building blocks are needed during DNA synthesis and repair. LÄS MER

  5. 4. Regulatory roles of sRNAs in pathogenesis of Vibrio cholerae

    Författare :Dharmesh Sabharwal; Sun Nyunt Wai; Bernt Eric Uhlin; Jörgen Johansson; Cynthia Sharma; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vibrio cholerae; sRNA; Biofilm; OmpT; RbmC; Vrp; VafA; mikrobiologi; Microbiology;

    Sammanfattning : The Gram-negative pathogen Vibrio cholerae uses variety of regulatory molecules to modulate expression of virulence factors. One important regulatory element of microorganisms is small non-coding RNAs (sRNAs), which control various cell functions such as expression of cell membrane proteins, mRNA decay and riboswitches.

  7. 5. RNA-mediated virulence gene regulation in the human pathogen Listeria monocytogenes

    Författare :Edmund Loh; Jörgen Johansson; Nancy Freitag; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Listeria monocytogenes; virulence; ncRNAs; PrfA; 5´-UTRs; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The Gram-positive human pathogen Listeria monocytogenes uses a wide range of virulence factors for its pathogenesis. The majority of its virulence genes are encoded on a 9-kb pathogenicity island and are controlled by the transcriptional activator PrfA. LÄS MER
