Expression of uPAR and PAI-1 in tumor tissues andadjacent normal mucosa of colon and rectal cancer patients. Mean concentration of uPAR (a, left panel) and PAI-1 (b, left panel) determined by ELISA. Fold increase of uPAR (a, right panel) and PAI-1 (b, right panel) in tumor tissues compared with normal tissues, showing no significant difference of increase in colon tumor and rectal tumor. ns, non-significant. **P < 0.01. ***P < 0.001.
