  1. 1. Regulation of hematopoiesis in the freshwater crayfish, Pacifastacus leniusculus : role of transglutaminase

    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ast1; clotting protein; crayfish; hematopoiesis; PVF PVR; ROS; transglutaminase; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Abstract : The freshwater crayfish, Pacifastacus leniusculus, has been used as a model for studying hematopoiesis or blood cell production or hematopoiesis and immunity. The work of this thesis aims to investigate the impact of factors such as ROS signaling, Ast1, and the PVF/PVR signaling pathway in controlling stem cell behavior during hematopoiesis and specifically the role of the crosslinking enzyme transglutaminase (TGase) in regulation of hematopoiesis.

    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; astakine; cytokine; hematopoiesis; prokineticin; transglutaminase; ATP synthase; innate immunity; apoptosis; Immunology; Immunologi; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Abstract : Hemocytes (blood cells) play an important role in the immune response in invertebrates, and thus the regulation of hemocyte homeostasis (hematopoiesis) is essential for the host survival against pathogens. Astakine 1, a homologue to vertebrate prokineticins, was first identified in the freshwater crayfish Pacifastacus leniusculus as a cytokine, and was found to be necessary for new hemocyte synthesis and release in vivo, and also to induce spreading and proliferation of Hematopoietic tissue cells (Hpt cells, precursor of hemocytes) in vitro.

  3. 3. Mitochondrial Iron Metabolism : Study of mitoferrin in Drosophila melanogaster

    Author : Christoph Metzendorf; Maria Lind Karlberg; Kenneth Söderhäll; Martina Muckenthaler; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; iron; Drosophila; mitochondria; mitoferrin; ferritin; spermatogenesis; cell cycle; DFO; MRS12; Cell and molecular biology; Cell- och molekylärbiologi; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Abstract : Iron has a dualistic character. On the one hand it is essential for the life of most organisms, on the other hand it is involved in the generation of reactive oxygen species that are implicated in diseases and aging. READ MORE
