1. Altered expression of contractile endothelin receptors in the vascular bed
Sammanfattning : This thesis aims at characterizing the endothelin (ET) receptors in different vascular beds of man and rat. The ET-A receptor was shown to be the only contractile ET receptor present in all vascular regions, with the exception of the rat mesenteric vein where a weak ET-B receptor-mediated contraction was seen.

2. Endothelin receptor changes during inflammation in the lung
Sammanfattning : Endothelin-1 (ET-1) is an extremely potent smooth muscle spasmogen well known from the vascular system but also active within the airways. The importance of its proinflammatory and co-mitogenic properties has become increasingly evident, the endothelin system also having been shown to mimic the signal features of asthma, COPD and other pulmonary diseases.

3. Cellulose synthases in Populus- identification, expression analyses and in vitro synthesis
Sammanfattning : Cellulose is a biopolymer of great relevance in the plant cell walls, where it constitutes the most important skeletal component. Cellulose is also an important raw material in the pulp- and paper, forest, and textile industries, among others. LÄS MER
4. Receptor Upregulation and MAPK Activity in Arteries and Bronchi Following Secondhand Smoke Exposure
Sammanfattning : Cigarette smoking is a major risk factor for cardiovascular and respiratory diseases. Contractile receptor changes have been observed in several vascular diseases. The intracellular mitogen activated protein kinase (MAPK) signaling pathways are suggested to be associated with receptor upregulation. LÄS MER
5. The significance of urokinase-type plasminogen activator (u-PA) in tumour growth and Linomide-induced upregulation of u-PA's endogenous inhibitor PAI-2
Sammanfattning : The progressive process of tumour invasion and generation of metastases is the primary cause of death for most patients with cancer. Some of the regulatory components of this progressive process are adhesion, migration, and proteolysis. LÄS MER
