TY - JOUR ID - 970398 AU - Halámková, Jana - Kiss, Igor - Pavlovský, Zdeněk - Jarkovský, Jiří - Tomášek, Jiří - Tuček, Štěpán - Hanakova, Lada - Moulis, Mojmír - Čech, Zbyněk - Zavřelová, Jiřina - Penka, Miroslav PY - 2011 TI - Clinical Relevance of uPA, uPAR, PAI 1 and PAI 2 Tissue Expression and Plasma PAI 1 Level in Colorectal Carcinoma Patients JF - Hepatogastroenterology VL - 58 IS - 112 SP - 1918-1925 EP - 1918-1925 SN - 01726390 KW - Colorectal cancer KW - Plasminogen activator system KW - PAI 1 KW - PAI 2 KW - uPA KW - uPAR N2 - Urokinase (uPA) is a serine protease, which together with uPAR, tPA, PAI 1 and PAI 2 forms the plasminogen activator system, a component of metastatic cascade contributing to the invasive growth and angiogenesis of malignant tumours. Methodology: Both preceding therapy and after 6-8 weeks of the treatment, plasma PAI 1 levels (photometric microplate method on the ELISA) and uPA, uPAR, PAI 1 and PAI 2 tissue expression (immunohistochemical reaction) were analysed from 80 colorectal carcinoma patients. Results: Analysis showed higher pre-treatment plasma levels of PAI 1 in patients with advanced tumours, which decreased after surgery or the start of therapy (p=0.004); Patients with higher plasma level PAI 1 before (0.013) and after therapy (0.004) had significantly shorter survival. There was a higher expression of uPA (p<0.001), uPAR (p<0.001), PAI 1 (p=0.042) and PAI 2 (p<0.001) in advanced colorectal carcinoma. A relationship between PAI 2 (p=0.010) and uPAR (p=0.019) expression and survival was demonstrated. There is a correlation between pre-treatment plasma PAI 1 levels and PAI 2 (p=0.028) and uPAR (p=0.043) expression. Conclusions: Immunohistochemical analysis of PAS in tumour tissue and plasma PAI 1 levels was found to be a useful prognostic factor in colorectal carcinoma patients. Plasma PAI 1 could be advantageous in evaluating the effectiveness of a mode of treatment. ER -
