1. 6. Retinoids and vitamin D in skin and parathyroid glands

   Författare :Liu Wei; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; all-trans retinoic acid 9-cis retinoic acid vitamin A. vitamin D. CRBP. CRABP. RAR. RXR. parathyroid hormone. calcium receptor; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Sammanfattning : Vitamin D3 (VitD3) and retinoids are important factors involved in differentiation and proliferation in many cell systems. Their effects in skin, where retinoids and vitamin D are known to be crucially involved in keratinocyte differentiation and function,, and in the parathyroid, the overall regulatory organ in calcium homeostasis were studied.

3. 7. Cyclin A1 Expression and Regulation in Hematopoietic and Leukemic Cells

   Författare :Jenny Ekberg; Malmö Patologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; General pathology; pathological anatomy; Patologi allmän ; patologisk anatomi; onkologi; Cytologi; cancerology; oncology; Cytology; AML; cyclin A1; apoptosis; cell cycle regulation;

   Sammanfattning : Increased expression of the cell cycle regulatory protein cyclin A1 has previously been detected in patients with acute myeloid leukemia (AML) and targeted overexpression of cyclin A1 in a transgenic mouse model initiated AML. The aim of this thesis was to further study the expression and regulation of cyclin A1 in hematopoietic cells. LÄS MER

4. 8. Apoptosis in the myelodysplastic syndromes : protective effect of G-CSF

   Författare :Jan Schmidt-Mende; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Increased apoptosis of hematopoietic progenitor cells is a hallmark for the myelodysplastic syndromes (MDS), and one of the main reasons for the ineffective hematopoiesis and subsequent cytopenia characteristic for the disease. In particular in low risk MDS, such as refractory anemia (RA) and refractory anemia with ringed sideroblasts (RARS), severe transfusion-dependent anemia leading to constant fatigue and weakness and therefore reduced quality of life often constitutes the main clinical problem.

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

   Författare :Hao Li; Hans Törmä; Anders Vahlquist; Mikael Ivarsson; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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.

7. 10. Molecular mechanisms for lineage-restricted differentiation of adult neural progenitors

   Författare :Muna Elmi; Göteborgs universitet; []
   Nyckelord :;

   Sammanfattning : Aims: In the central nervous system of several species, including humans, neurogenesis per?sists even in the adult life in discrete neurogenic regions of the brain. Adult neural stem cells derived from these neurogenic areas are proliferating cells, which can differentiate to neurons, astrocytes, and oligodendrocytes. LÄS MER
