Assessing the ERG rearrangement for clinincal use in patients with prostrate cancerSvensson, Maria January 2013 (has links)
In Sweden, close to 10 000 men are annually diagnosed with prostate cancer (PCa) and approximately 2400 men die of their disease each year. Today there is no reliable marker that can separate patients who will have an aggressive type of disease that requires treatment, from patients who will have a more indolent clinical course and can be left untreated. This further leads to the current problem of over treatment of men with PCa. Hence, there is an urgent need for reliable prognostic markers that can be used at time of diagnosis. With the discovery of recurrent gene rearrangements in PCa, most commonly ERG rearrangements, hope came that this aberration could play a role in diagnosis and/or prognosis of the disease. The aim of this thesis was to investigate the clinical implication of ERG rearrangements in the management of PCa. The work in this thesis supports the findings from previous studies, suggesting that the ERG rearrangement is a sign of a more aggressive type of cancer. The major findings are that in multifocal PCa, the ERG rearranged cancer foci are more prone to metastatic dissemination compared to foci without the ERG rearrangement and that patients harboring the ERG rearrangement have a faster disease progression leading up to earlier start of hormonal treatment. Furthermore, the results add an additional level of complexity in a subset of PCa tumors that harbor multiple gene rearrangements on the cellular level. The result also show that the newly available ERG antibody is highly predictive of ERG rearrangement and is appropriate to use when faced with limitations in tissue amounts. The findings in this thesis indicate that the ERG rearrangement has a potential role in the clinical management of PCa but further studies arerequired.

Development of Organ-Specific Progenitor Cell Cultures as Efficacy Test Platforms for Electron-Spun Fibre Meshes in Regenerative Medicine ApplicationsRajendran, Vijayalakshmi January 2011 (has links)
The nervous and cardiovascular system plays the most complex and vital role in all organisms. Any damage or injury to these essential organs in our body results in long term irreversible impairment or death. The main goal of the regenerative medicine is to repair or recreate tissues using stem cells to restore the vital function of the targeted organ. Along with organ specific stem/progenitor cells, non-toxic, biodegradable synthetic polymers are also needed for an effective reparative therapy. The effect of PCL materials and surface modified (PEDOT coated) PCL materials of different topology with neural progenitor cells as test platforms are evaluated for cytotoxicity and neuron differentiation. The stem cells from heart are isolated and characterized as cardiac stem cells by Fluorescence activated cell sorting through specific antigen expression. The cardiac stem cells are used to establish effective proliferation and differentiation system. Hence, developing cardiac and neural progenitor cell cultures as an efficacy test platforms for biomaterials of different diameter and orientation benefits respective tissue engineering with proper restoration of function. Further, the nerve and cardiac tissue rejuvenation would serve as a regenerative therapy for numerous neurodegenerative disorders and cardiovascular disorders like myocardial infarction respectively.
