miR-711 was upregulated in patients with breast cancer and was associated with a poor survival time. (A) Expression levels of miR-711 in 30 paired T and N tissues, detected using reverse transcription-quantitative polymerase chain reaction. The relative expression level was normalized to small nuclear RNA U6. Paired Student's t-test was performed; data are presented as the mean ± standard deviation; **P<0.01. (B) miR-711 expression in tissues from patients with breast cancer is associated with overall survival time. (C) miR-711 expression in tissues from patients with breast cancer is associated with disease-free survival of the patients. Log rank tests were performed to compare the survival times. miR-711, microRNA-711; T, breast cancer tissue; N, normal adjacent breast tissue.
