  1. 1. Regulation of Fibroblast Activity by Keratinocytes

    Author : Daniel Nowinski; Mikael Ivarsson; Bengt Gerdin; Elof Ph D M.D. Eriksson; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; conective tissue growth factor; interleukin-1; fibroblast; keratinocyte; wound healing; burns; Kirurgi; Surgery; Kirurgi;

    Abstract : In the healing of cutaneous wounds, paracrine communication between keratinocytes and fibroblasts regulates cell differentiation, proliferation and synthesis of extracellular matrix. Deficient epidermal coverage, as seen in burn-wounds, frequently results in hypertrophic scars. READ MORE

  2. 2. Quantification of Radiation Induced DNA Damage Response in Normal Skin Exposed in Clinical Settings

    Author : Martin Simonsson; Ingela Turesson; Gunilla Enblad; Dag Rune Olsen; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA damage response; low-dose hypersensitivity; dose response; normal tissue; epidermis; dermis; keratinocyte; fractionated radiotherapy; DNA double strand break; DSB; foci; gamma-H2AX; 53BP1; p21; checkpoint; apoptosis; mitosis; micro-RNA; miR-34a; Oncology; Onkologi; Oncology; Onkologi;

    Abstract : The structure, function and accessibility of epidermal skin provide aunique opportunity to study the DNA damage response (DDR) of a normaltissue. The in vivo response can be examined in detail, at a molecularlevel, and further associated to the structural changes, observed at atissue level. READ MORE

  3. 3. Studies on Vitamin A Signaling in Psoriasis : A Comparison Between Normal and Lesional Keratinocytes

    Author : Teresa Karlsson; Jan Öivind Moskaug; Uppsala universitet; []
    Keywords : Medical sciences; Psoriasis; vitamin A; retinoids; retinoid receptor; differentiation; keratinocyte; skin; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Dermatology and Venerology; dermatologi och venereologi;

    Abstract : Vitamin A and metabolites (retinoids) are crucial for normal epidermal maturation. Physiological effects are mediated by retinoic acid (RA) that activates nuclear retinoic acid receptors (RARs) in complexes with retinoid X receptors (RXRs), resulting in altered gene transcription.Psoriasis is a common disease with unknown etiology.

  4. 4. Regulation of fibroblast activity by keratinocytes, TGF-β and IL-1α : studies in two- and three dimensional in vitro models

    Author : Anita Koskela von Sydow; Mikael Ivarsson; Torbjörn Bengtsson; Hans Törmä; Örebro universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fibroblast; Keratinocyte; TGF-β; IL-1α; coculture; fibrosis CTGF CNN 2; dermal; organotypic culture;

    Abstract : Dysregulated wound healing is commonly associated with excessive fibrosis. Connective tissue growth factor (CTGF/CCN2) is characteristically overexpressed in fibrotic diseases and stimulated by transforming growth factor-β (TGF-β) in dermal fibroblasts. Reepithelialisation and epidermal wound coverage counteract excessive scar formation. READ MORE

  5. 5. DNA Damage Response of Normal Epidermis in the Clinical Setting of Fractionated Radiotherapy : Evidence of a preserved low-dose hypersensitivity response

    Author : Fredrik Qvarnström; Ingela Turesson; Gunilla Enblad; Mats Harms-Ringdahl; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA damage response; low-dose hypersensitivity; dose response; normal tissue; epidermis; keratinocyte; fractionated radiotherapy; DNA double strand break; DSB; foci; γH2AX; 53BP1; checkpoint; p21; apoptosis; mitosis; Oncology; Onkologi; Oncology; onkologi;

    Abstract : Investigations of DNA damage response (DDR) mechanisms in normal tissues have implications for both cancer prevention and treatments. The accumulating knowledge about protein function and molecular markers makes it possible to directly trace and interpret cellular DDR in a tissue context. READ MORE
