Figure 2. Expression levels of miRNAs, PSA, PCA3, and Fra-1 genes. Real-time PCR exhibited similar expression levels of the three miRNAs (left column) and Fra-1 gene (mid-right) in PCa and BPD tissue samples. Expression levels of PCA3 (bottom-right) and PSA (top-right) genes were significantly higher in PCa than in BPD samples. Error bars indicate ± SD.
