  1. 11. Evolution of a family of plant genes with regulatory functions in development; studies on Picea abies and Lycopodium annotinum

    Författare :Mats Svensson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk botanik; Physiological Botany;

    Sammanfattning : This work is focused on the molecular genetic basis for morphological change in evolution. Genes belonging to the MADS-box gene family, which includes members, that determine angiosperm floral organ identity, were isolated and characterised from two non-angiosperm plants; Norway spruce (Picea abies) and the club moss (Lycopodium annotinum).

  3. 12. Characterisation of Members of the HD-Zip I and DREB/ERF Transcription Factor Families and their Functions in Plant Stress Responses

    Författare :Elin Övernäs; Peter Engström; Jaako Kangasjärvi; Uppsala universitet; []
    Nyckelord :Fysiologisk botanik; Physiological Botany;

    Sammanfattning : Plants have to adapt to various environmental conditions. In comparison with other eukaryotes, plant genomes encode relatively many transcription factors, and have families of transcription factors only found in plants, two such are the large AP2/ERF (APETALA2/Ethylene Responsive Factor) and HD-Zip (Homeodomain leucine zipper) families.

  4. 13. Molecular and physiological functions of LRIG proteins and netrin-1 in health and disease

    Författare :Carl Herdenberg; Håkan Hedman; Richard Palmqvist; Maréne Landström; Aristidis Moustakas; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LRIG; Netrin-1; LRIG1; LRIG2; LRIG3; Type 2 diabetes; Oncology; onkologi;

    Sammanfattning : The leucine-rich repeats and immunoglobulin-like domains (LRIG) gene family has three members, LRIG1, LRIG2, and LRIG3, that encode three structurally similar transmembrane proteins. LRIG1 is a receptor tyrosine kinase regulator, tumor suppressor, and stem cell marker in the skin, intestine, and brain. LÄS MER

  5. 14. Alternative NAD(P)H dehydrogenases in plant mitochondria - localisation, catalytic functions and physiological roles

    Författare :Agnieszka Michalecka; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kärlväxters fysiologi; Physiology of vascular plants; NAD P H dehydrogenase; light-dependence; electron transport chain; alamethicin; alternative oxidase;

    Sammanfattning : In addition to complex I, the plant mitochondrial electron transport chain possesses several alternative NAD(P)H dehydrogenases, not present in animals. These enzymes allow nonenergy-conserving electron transfer from cytoplasmic and matrix NAD(P)H to ubiquinone. LÄS MER

  7. 15. Functions and memory features of adaptive- and innate immune cells in physiological and inflammatory settings

    Författare :Gintare Lasaviciute; Eva Sverremark-Ekström; Silke Appel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Innate immune memory; Limosilactobacillus reuteri; dendritic cells; lymphocytes; cytokines; immunological memory; intestinal epithelial cells; chemotherapy; bone marrow; secondary lymphoid organs; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The immune system is a complex but well-regulated network which cooperates with the microbiota to maintain optimal homeostasis under physiological settings. A number of factors display the capacity to alter the immune system and thus microbiota crosstalk including host genetics, diet, environmental influences and drugs such as antibiotics or chemotherapeutic agents.
