  2. 1. Maf transcription factors in beta cell function

    Author : Elvira Ganic; Stamcellscentrum (SCC); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Beta cell; MafA; type 2 diabetes; insulin secretion; transcription; monoamine oxidase; MaoA; MaoB; nicotinic receptor subunits; nAChRs;

    Abstract : Diabetes mellitus is metabolic disorder caused by a defect or lack of beta cell-produced insulin that controls blood glucose homeostasis. In addition to glucose, insulin secretion is regulated by the autonomic nervous system (ANS); the neurotransmitter acetylcholine as well as monoamines, such as dopamine, serotonin, melatonin and norepinephrine.

  4. 2. Unique Solutions to Universal Problems : Studies of the Archaeal Cell

    Author : Erik A. Pelve; Rolf Bernander; Sonja Verena Albers; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Archaea; Cdv; Cell cycle; Cell division; Cell lysis; Crenarchaea; ESCRT-III; Flow cytometry; Microarray; Microscopy; Nitrosopumilus; SIRV2; Sulfolobus; Thaumarchaea; Transcription; VAP; Virus; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Abstract : Archaea is one of the three domains of life and studies of archaeal biology are important for understanding of life in extreme environments, fundamental biogeochemical processes, the origin of life, the eukaryotic cell and their own, unique biology. This thesis presents four studies of the archaeal cell, using the extremophilic Sulfolobus and ocean living Nitrosopumilus as model systems. READ MORE

  5. 3. Understanding and manipulating primary cell walls in plant cell suspension cultures

    Author : Felicia Leijon; Vincent Bulone; Katja Salomon Johansen; KTH; []
    Keywords : Callose synthase; carbohydrate-binding module; cell wall engineering; cellulose microfibril; cellulose nanocrystal; glycosyltransferase; mass spectrometry; plasmodesmata; Populus; primary cell wall; radiometric assay; spectrophotometric assay; Biotechnology; Bioteknologi;

    Abstract : The cell wall is required for many aspects of plant function and development. It is also an accessible and renewable resource utilized both in unrefined forms and as raw material for further development. Increased knowledge regarding cell wall structure and components will contribute to better utilization of plants and the resources they provide. READ MORE

  6. 4. Fibroblast Growth Factor Receptor-1 Function in Vasculo- and Angiogenesis

    Author : Peetra Magnusson; Lena Claesson-Welsh; Anne Eichmann; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; FGF; FGFR-1; VEGFR-2; PDGFR-β; endothelial cells; embryonic stem cell; angiogenesis; hematopoiesis; Patologi; Pathology; Patologi;

    Abstract : During development of the mammalian embryo, spatial and temporal expression of fibroblast growth factors (FGFs) and their cognate receptors are vital in the regulation of a number of patterning processes. Inappropriate or decreased expression leads to severe malformations and even embryonic death. READ MORE

  7. 5. Transcriptional and post-transcriptional regulation of vascular smooth muscle cell phenotype - Implications for vascular disease states

    Author : Azra Alajbegovic; Molekylär kärlfysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Vascular smooth muscle cells VSMC ; cell phenotype; microRNA; Aneurysm; hypertension; Actin polymerization; GATA6; MRTFA; Vascular disease;

    Abstract : As the world population is pushing toward 8 billion, cardiovascular diseases (CVD) remain the leading cause of death worldwide, representing 30% of all global deaths. A large body of work has recognized that smooth muscle cells (SMCs) surrounding the blood vessels play a prominent role in the development and progression of cardiovascular diseases. READ MORE
