Relative miRNA expression levels between PCa patients with PSA (< 4 ng/ml) after treatment and control groups. a miR-1825 expression was significantly higher in PCa patients with PSA < 4 ng/ml than controls. b miR-484 expression was significantly lower in PCa patients with PSA < 4 ng/ml than controls. c miR-205 expression was significantly lower in PCa patients with PSA < 4 ng/ml than in control; d miR-141 was significantly higher in PCa with PSA < 4 than controls. e Let-7b expression was significantly lower in PCa patients with PSA < 4 ng/ml than controls. PCa with PSA < 4, prostate cancer patients with PSA < 4 ng/ml after treatment; control, healthy group. Results are shown as means ± SD. *p < 0.05, **p < 0.01, ***p < 0.001
