1. 1. Transcriptional dysregulation in L-DOPA-induced dyskinesia

   Författare :Malin Andersson; Neurobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical genetics; neurofysiologi; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; CREB; jun; fos; immediate early genes; prodynorphin; striatal plasticity; Parkinson s disease; dyskinesia; Klinisk genetik;

   Sammanfattning : This study explores the role of transcriptional regulation important in the development of L-DOPA-induced dyskinesia in a rat model of Parkinson’s disease. In patients with Parkinson’s disease, dyskinesia is one of the most difficult complications of the DA-replacement therapy by L-DOPA. LÄS MER

3. 2. Regulation of survival and proliferation of human intestinal epithelial cells by leukotriene D4

   Författare :Sailaja Paruchuri; Malmö Experimentell patologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rac; General pathology; pathological anatomy; Patologi allmän ; patologisk anatomi; PI3K; CREB; p90RSK; Erk-1 2; PKC; inflammation; migration apoptosis; proliferation; LTD4; cell survival;

   Sammanfattning : The pro-inflammatory mediator, Leukotriene D4 (LTD4) is a product of arachidonic acid cascade and has been implicated in asthma and inflammatory bowel diseases. Prolonged inflammatory conditions like ulcerative colitis increases the risk for the development of cancer and the factors that induce the chronic immune response remain uncertain. LÄS MER

4. 3. ADP regulation of insulin secretion and beta-cell apoptosis

   Författare :Chanyuan Tan; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; P2Y; β-cell; ADP; insulin; apoptosis; autocrine; ectonucleotidase;

   Sammanfattning : The aims of this dissertation were to investigate the effects of extracellular purines on insulin secretion, and apoptosis in mouse pancreatic islets and β-cells; to examine if high glucose and free fatty acids induces β-cell apoptosis via autocrine effects of ADP acting on the P2Y13 receptor; and to investigate the modulation of extracellular purines in vascular smooth muscle cells (VSMCs) through ectonucleotidase or ATP release under the effect of high glucose. The expression of the ADP receptors P2Y1 and P2Y13 were shown in both mouse pancreatic islets and isolated β-cells using real-time PCR quantification. LÄS MER

5. 4. From adrenergic signalling to gene expression : a study in brown adipocytes

   Författare :Håkan Thonberg; Paul Trayhurn; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoofysiologi; Zoological physiology;

   Sammanfattning : Many external stimuli influence gene expression in cells by first interacting with cell surface receptors. For alteration of the expression of a gene, the signal has to be passed into the nucleus. This is facilitated by particular proteins/molecules in a signal transduction cascade. LÄS MER

7. 5. Role of DARPP-32 in Breast Cancer Cell Signalling and Migration

   Författare :Christian Hansen; Molekylär neurobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell migration; protein phosphatase 1.; DARPP-32; breast cancer; protein kinase A;

   Sammanfattning : Breast cancer is the most common form of cancer in women. While the prognosis for breast cancer patients without local or distal dissemination is relatively favorable, the prognosis is considerably worse once distal metastasis has been established. LÄS MER
