  3. 2. Signal integration between notch and hypoxia : insights into development and disease

    Författare :Maria Gustafsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Oxygen is essentially required for aerobic metabolism in most eukaryotic organisms. Therefore, it is striking that a number of tissues develop, and are maintained at low oxygen (hypoxic) conditions in the body. For instance, the human embryo is located in a hypoxic environment.

  4. 3. Mechanisms of cell type-specific gene transcription : studies on the choline acetyltransferase gene

    Författare :Peter Lönnerberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Choline acetyltransferase (ChAT) is the enzyme synthesizing the neurotransmitter acetylcholine. Previous studies from our laboratory on the regulation of the cholinergic phenotype have suggested the presence of regulatory elements in the ChAT gene controlling accurate time- and cell-specific expression.

  5. 4. Regulation of cellular responses to hypoxia by HIF-1alpha-dependent and -independent signaling pathways

    Författare :Xiaofeng Zheng; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Hypoxia is a state of inadequate oxygen supply to the cells and tissues of the body. It plays a critical role in embryonic development, as well as in various physiological and pathological processes. LÄS MER

  7. 5. The actinorhizal plant Datisca glomerata : interpreting its symbiotic adaptations by omics-based comparisons with model and non-model organisms

    Författare :Marco Salgado; Katharina Pawlowski; Daniel Lundin; Rene Geurts; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Root nodule symbiosis; nitrogen fixation; actinorhizal; Datisca glomer-ata; Frankia; nodule development; defensin; antimicrobial; carboxylate transporter; phylogenomics; transcriptomics; Plant Physiology; växtfysiologi;

    Sammanfattning : Nitrogen is the element that most often limits plant growth and development. Common agricultural practices rely on the application of large quantities of industrially-produced nitrogen fertilizer, which poses a worldwide environmental threat. Sustainable agriculture encourages the use of biologically fixed nitrogen. LÄS MER
