1. 1. Qualitative and Quantitative Assessment of Cytochromes P450 mRNA in Human : Studies in the Liver, Blood and Gastrointestinal Mucosa

   Författare :Mari Thörn; Lars Lööf; Anders Rane; Ellen Vinge; Uppsala universitet; []
   Nyckelord :Medical sciences; cytochrome P450; CYP1A2; CYP1B1; CYP2E1; CYP3A4; CYP3A5; P-gp; gene expression; RT-PCR; liver; blood; gastrointestinal mucosa; MEDICIN OCH VÅRD; MEDICINE; MEDICIN;

   Sammanfattning : Drugs and other foreign compounds must often be metabolised before they can be excreted from the body. One enzyme system that is responsible for this is the cytochrome P450 gene family (CYP). LÄS MER

3. 2. Radiolabelled Oligonucleotides for Evaluation of in vivo Hybridisation Utilising PET Methodology

   Författare :Gábor Lendvai; Mats Bergström; Sergio Estrada; Barbro Eriksson; Raymond Josephsson; Bertrand Tavitian; Uppsala universitet; []
   Nyckelord :Molecular medicine; Gene expression; Antisense oligonucleotides; Positron emission tomography; In vivo hybridisation; In vivo biodistribution; Chromogranin-A; 68Ga; RT-PCR; Scavenger receptors; Molekylärmedicin;

   Sammanfattning : Antisense oligonucleotides (ODN) may interfere in gene expression on the basis of hybridising to its complementary messenger RNA (mRNA) sequence in the cell thereby preventing the synthesis of the peptide. Therefore, these ODNs may be potential drugs to treat human diseases by “knocking down” the expression of responsible genes or correcting the maturation process of mRNA in the field called antisense therapy.

4. 3. Vascular endothelial growth factor in renal cell carcinoma

   Författare :Jan Jacobsen; Börje Ljungberg; Kjell Grankvist; Torgny Rasmuson; Anders Bergh; Peter Ekman; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VEGF; isoforms; quantitative RT-PCR; immunohistochemistry; tissue microarray; Western blot; stage; survival; renal cell carcinoma; Urology and andrology; Urologi och andrologi;

   Sammanfattning : Background. Angiogenesis is essential for tumour growth. Vascular endothelial growth factor (VEGF) and its isoforms were investigated in relation to the clinical course in a large number of patients with renal cell carcinoma (RCC). Methods. LÄS MER

5. 4. Methodological studies of eicosanoid enzyme gene expression in vascular endothelium exposed to biomechanical stress

   Författare :Roya Doroudi; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostanoids; endothelium; quantitative RT-PCR; perfusion model; shear stress; intraluminal pressure; immediate-early genes;

   Sammanfattning : Prostaglandins are the major eicosanoids synthesized by vascular endothelial cells, and the vasculature is an important target organ for their bioactive metabolites. In vitro studies have shown that biomechanical forces are important regulators of vascular expression of prostanoid enzymes and release of metabolites. LÄS MER

7. 5. Islet Xenotransplantation : An Experimental Study of Barriers to Clinical Transplantation

   Författare :Peter Schmidt; Olle Korsgren; Bo Nilsson; Karin Ulrichs; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; xenotransplantation; islets of Langerhans; rejection; diabetes; porcine endogenous retroviruses; quantitative RT-PCR; cytokines; animal models; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

   Sammanfattning : In the field of transplantation, the increasing deficit of human donors have lead to an interest in animals as an alternative source of organs and tissues. Different in vitro systems and rodent models of xenotransplantation were used to examine the most significant barriers that have to be overcome, before isolated islets of Langerhans from pigs can be used as a cure for insulin-dependent diabetes mellitus in humans.
