Although data comparison between different reports is complicated or even confounded by methodological differences (e.g., histological protocols, detection antibodies, and mRNA probes employed, lack of appropriate specificity controls, surgical specimen available, etc.)and tumor complexity, the results of most studies collectively point in the same direction and allow the identification of some general features of uPAR expression in cancer, regardless of the tumor type. Here, PLAUR is linked to neoplasm.
