Relative miRNA expression in multiple stratified analysis. a miR-1825 expression was significantly higher before treatment than after. b Let-7b expression was significantly higher in patients with PSA < 4 ng/ml than those with PSA > 4 ng/ml. c miR-1825 expression was significantly higher in patients at stage T3–T4 than those at stage T1–T2. d Let-7b expression was significantly lower in patients at stage T3–T4 than those at stage T1–T2. e miR-205 expression was significantly higher in patients with bone metastasis than in those without. f Let-7b expression was significantly higher in hormone-dependent group than in hormone-resistant group: before, prostate cancer patients treated without PSA; after, prostate cancer patients treated without PSA. PSA < 4, PCa patients treated with PSA < 4 ng/ml; PSA > 4, PCa patients treated with PSA > 4 ng/ml. T1–T2, low TNM score group; T3–T4, high TNM score group. Dependent, PCa patients in the hormone-dependent group; resistant, PCa patients in the hormone-resistant group. Results are shown as means ± SD. *p < 0.05
