  1. 1. On keratin mutations in epidermolytic hyperkeratosis and the regulation of keratin expression by retinoids

    Author : Marie Virtanen; Uppsala universitet; []
    Keywords : Medical sciences; EHK; keratin; retinoids; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Dermatology and Venerology; dermatologi och venereologi;

    Abstract : Epidermolytic hyperkeratosis is a rare inherited disease of the skin caused by a dominant-negative mutation in keratin 1 (K1) or 10 (K10). Keratins are the major structural protein in epidermis and mutations causes instability of intermediate filament and keratinocyte fragility. READ MORE

  2. 2. Retinoids in experimental neuroblastoma therapy

    Author : Frida Ponthan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Vitamin A; retinoids; neuroblastoma; 9-cis RA; Ro 13-6307; differentiation; apoptosis; growth inhibition; 13-cis RA; fenretinide; proton magnetic resonance spectroscopy; pharmacokinetic.;

    Abstract : Retinoids are analogues of vitamin A, with documented activity against various malignant cell types. Neuroblastoma is a childhood tumour of the sympathetic nervous system that shows a complex clinical and biological heterogeneity, often with poor outcome despite intensive multimodal therapy.

    Abstract : Autosomal dominant epidermolytic ichthyosis (EI) is a rare disease characterized by intra-epidermal blistering due to mutations in either of two keratin genes, KRT1 and KRT10, expressed by suprabasal keratinocytes. Autosomal recessive congenital ichthyosis (ARCI) is a non-blistering, hyperkeratotic disease caused by mutations in one of the following genes: ABCA12, ALOX12B, ALOXE3, TGM1, CYP4F22, NIPAL4 and SLC27A4, which are all essential for skin barrier homeostasis.

  4. 4. 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.

  5. 5. Molecular mechanism of cell regulatory properties of vitamin D analogues in human cancer cell lines

    Author : Carina Danielsson; Uppsala universitet; []
    Keywords : Medical sciences; vitamin D analogues; retinoids; cancer cell lines; promoter selectivity; cell regulatory properties; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Dermatology and Venerology; dermatologi och venereologi;

    Abstract : The active form of vitamin D, 1α,25-dihydroxyvitamin D3, is a potent modulator of the induction of differentiation and inhibition of cell growth in both malignant and normal cells. Vitamin D and its analogues exert their effects through a transcription factor, the nuclear vitamin D receptor (VDR). READ MORE
