  2. 1. Growth control mechanisms in normal and neoplastic mammalian cells

    Author : Mozhgan Afrakhte; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; PDGF-AA; TGF-beta; Inhibitory SMADs; Growth inhibition; CDK; CKI; Cdc25A; Genetik; Clinical genetics; Klinisk genetik; Genetics; genetik;

    Abstract : The main theme of the studies presented in this thesis is, the growth control mechanisms whose loss in normal cells predispose to or cause cancer. The balance between growth inhibitory and stimulatory mechanisms is crucial for the development and maintenance of a normal animal. READ MORE

  4. 2. Aspects of Tumour Targeting : Preclinical Studies on Human Malignant Cells in vitro

    Author : Maria Dahlström Wester; Annelie Lindström; Åke Wasteson; Lars Gedda; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Exclusive eradication of tumour cells causing minimal damage to healthy tissue, a concept referred to as targeting, is an interesting approach to improve the outcome for patients afflicted with cancer.The general aim of this thesis was to highlighten aspects that could be of importance in developing novel treatment regimens based on specific targeting of tumour cells.

  5. 3. Neural Stem and Progenitor Cells : Cellular Responses to Known and Novel Factors

    Author : Jimmy Larsson; Karin Forsberg-Nilsson; Ola Hermanson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neural stem cell; differentiation; proliferation; migration; PDGF; SCF; NRBP2; medulloblastoma; Biochemistry; Biokemi; Medical Biochemistry; Medicinsk biokemi;

    Abstract : Neural stem cell self-renewal and differentiation are tightly regulated events during CNS development, leading to cell division into new neural stem cells or the formation of neurons and glial cells. This thesis focuses on the cellular responses induced by known and novel factors in neural stem and progenitor cells (NSPCs). READ MORE

  6. 4. Activation of the novel PDGFS by plasminogen activators in tumorigenesis

    Author : Monika Ehnman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Members of the platelet-derived growth factor (PDGF) family are mitogens for cells of a mesenchymal origin and have important functions both during development and in the adult. Their role in developmental processes has been extensively investigated by methodical targeted gene inactivations, revealing critical involvement in microvascular pericyte recruitment, neural crest development and alveogenesis.

  7. 5. Effects of growth factors on chondrocyte proliferation and differentiation

    Author : Caroline Edwall-Arvidsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Growth plate cartilage; limb buds; growth factors; proliferation; differentiation; collagens; c-fos; ALP;

    Abstract : Longitudinal bone growth is regulated at the level of growth plate chondrocytes by circulating or locally produced hormones and growth factors. Present investigation focused on the effects of growth hormone (GH) and growth factors on chondrocyte proliferation and differentiation during pre- and postnatal cartilage development. READ MORE
