  3. 7. UVA/B induced redox alterations and apoptosis in human melanocytes

    Författare :Petra Wäster Larsson; Inger Rosdahl; Karin Öllinger; Ian Cotgreave; Linköpings universitet; []

    Sammanfattning : Malignant melanoma is one of the most rapidly increasing cancers and accounts for about three-quarter of all skin cancer deaths worldwide. Despite compelling evidence that ultraviolet (UV) irradiation causes melanoma the knowledge how various wavelength spectra affect the balance between proliferation and apoptosis controlling the homeostasis of the melanocyte population is still limited.

  4. 8. Studies on cellular vitamin A metabolism and effects of UV irridation in human keratinocytes and melanocytes

    Författare :Eva Andersson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Reinoids (vitamin A and its derivatives) are modulators of proliferation and differentiation in a variety of cell types, including epidermal cells. Both retinol (ROH) and its metabolite 3,4-didehydroretinol (ddROH) can be converted to the acid form retinoic acid (RA) and 3,4-didehydroretinoic acid (ddRA), ligands for the nuclear receptors inducing gene transcriptions.

  7. 10. Dynamics and gene expression of growth factor receptors in human cultured skin cells : Effects of UV radiation and calcium on EGF- and PDGF-receptors

    Författare :Margareta Lirvall; Gunnar Kratz; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Growth factors transmit biological signals for the stimulation of cell growth and their stimulation may be involved in turnourigenesis. It is therefore of great importance to understand growth factor receptor reactions in response to stimuli such as calcium depletion or ultraviolet radiation, which normal human cells are invariably exposed to during their growth cycle.
