  1. 1. CYP26B1 as regulator of retinoic acid in vascular cells and atherosclerotic lesions

    Author : Ali Ateia Elmabsout; Allan Sirsjö; Karin Fransén; Helen Håkansson; Örebro universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CYP26B1; alternative splice; vascular cells; atherosclerosis; alltrans-retinoic acid; gene polymorphism; inflammation; statins; Medicin; Medicine;

    Abstract : Cardiovascular disease (CVD), currently the most common cause of morbidity and mortality worldwide, is caused mainly by atherosclerosis. Atherosclerosis is a chronic multifocal, immunoinflammatory, fibroproliferative disease of medium and large arteries. READ MORE

  2. 2. Vitamin A regulated neuronal regeneration and homeostasis

    Author : Sofia Håglin; Anna Berghard; Staffan Bohm; Leif Carlsson; Ola Hermanson; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Activity dependent; Adult stem cells; Ageing; CYP26B1; Homeostasis; Metaplasia; Neurogenesis; Olfactory epithelium; Regeneration; Respiratory epithelium; Retinoic acid; Sensory map; Vitamin A;

    Abstract : The olfactory epithelium is a dynamic tissue maintained by continuous neurogenesis throughout life. Upon injury, neurons and other olfactory cell types are regenerated through proliferation of horizontal stem cells. Some genes that regulate vitamin A metabolism are spatially expressed in the olfactory epithelium. READ MORE

  3. 3. Activity-regulated retinoic acid signaling in olfactory sensory neurons

    Author : Hande Login; Staffan Bohm; Mattias Alenius; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mouse olfactory system; RA; neuronal activity; CNG; Cyp26B1; BACE1; Kirrel-2; molekylärbiologi; Molecular Biology;

    Abstract : The aim of the studies included in the thesis is to better understand the interplay between neuronal activity-dependent gene regulation and the bioactive vitamin A metabolite all-trans-retinoic acid (RA) during postnatal development, refinement and maintenance of precise neuronal connectivity using the olfactory sensory neuron (OSN) in the olfactory epithelium (OE) of genetically modified mice as a model. We show that:Inhibition of RA receptor (RAR)-mediated transcription in OSNs reduces expression of the olfactory cyclic nucleotide-gated (CNG) ion channel, which is required for odorant receptor (OR)-mediated stimulus transduction.

  4. 4. Retinoic Acid Metabolism Blocking Agents and the Skin : In vivo and in vitro Studies of the Effects on Normal and Diseased Human Epidermis

    Author : Elizabeth Pavez Loriè; Anders Vahlquist; Hans Törmä; Marie Virtanen; Helen Håkansson; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CYP; CYP26; retinoids; vitamin A; RAMBA; metabolism; keratinocyte; epidermis; retinoid regulated genes; Dermatology and venerology; Dermatologi och venerologi;

    Abstract : Retinoic Acid Metabolism Blocking Agents (RAMBAs) increase the endogenous levels of all-trans retinoic acid (RA) by inhibiting CYP26 enzymes. Thus they are believed to mimic the effects of retinoid treatment. Their mechanism of action and effects on vitamin A metabolism in keratinocytes are however uncertain. READ MORE

  5. 5. In vitro Studies of Genodermatoses Affecting Cytoskeletal Integrity and Lipid Processing in Human Epidermis : Pathogenic Mechanisms and Effects of Retinoid Therapy

    Author : Hao Li; Hans Törmä; Anders Vahlquist; Mikael Ivarsson; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Congenital Ichthyosiform Erythroderma; Epidermolytic Hyperkeratosis; Ceramides; Keratins; Retinoids; Molecular Probe Techniques; Transglutaminases; Lipoxygenases; Fatty Acid Transporter Proteins; Keratinocytes; Epidermis; Medicinsk vetenskap; Medical Science;

    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.
