Figure 4From: Increased expression of urokinase plasminogen activator and its cognate receptor in human seminomas Correlation analysis between tumor size or patient's age and uPA or uPAR mRNA variations. Folds of mRNA variations in seminomas versus normal tissues were calculated as described in Materials and Methods section. The correlation analysis between uPA or uPAR mRNA variations and tumor size or patient's age were performed by the Spearman correlation test.Back to article page
