Study design and Selection of plasma miRNA candidates. (a) Study design to find novel candidate miRNAs that decreased in patient plasma as a therapeutic target for PCa. (b) Using a miRNA array-based approach, we found decreased plasma miRNAs with tumor suppressor functions by comparing the plasma levels of each miRNA between PCa patients and healthy volunteers. (c) Small-scale analysis of the plasma levels of six miRNAs in PCa patients and healthy volunteers by qRT-PCR. We investigated the plasma levels of the six selected miRNAs in 10 PCa patients and 10 healthy volunteers by qRT-PCR. The miRNA array-based approach showed that all six candidate miRNAs tended to be lower in the plasma of PCa patients than in that of healthy volunteers, and the change in the expression of miR-107 (P = 0.027) was found to be the most significant.
