Microribonucleic acid-451 is silenced in tumor tissues and correlated with poor prognosis of patients with metastatic castration-resistant prostate cancer.

(a) miR-451 expression detected by qRT-PCR in normal prostate tissues (n = 18) and tumor tissues (n = 59); the cut-off value (0.895) of tumor tissues was determined by an ROC curve; (b) miR-451 expression levels in normal prostate tissues and prostate cancer tissues of varying Gleason scores; (c) Kaplan–Meier analysis of the correlation between miR-451 expression and PFS of mCRPC patients; (d) Kaplan–Meier analysis of the association between miR-451 expression and OS of mCRPC patients.

*p < 0.05; #p < 0.05, ##p < 0.01.

mCRPC, metastatic castration-resistant prostate cancer patients; miR-451, microribonucleic acid-451; OS, overall survival; PFS, progression-free survival; qRT-PCR, quantitative reverse-transcription polymerase chain reaction; ROC, receiver operating characteristic.
