FENDRR had low expression in breast cancer tissues and cell lines, and was associated with good prognosis in breast cancer patients.

Notes: (A) FENDRR expression is examined by quantitative real-time PCR in 52 paired human breast cancer tissues and adjacent noncancerous tissues. Data are represented as log 2-fold change (tumor/normal). The patients were divided into a FENDRR low expression group (16) and a FENDRR high expression group (36) according to the mean value of relative FENDRR expression. (B) Overall survival in high and low FENDRR-expressing breast cancer tissues. (C) Progression-free survival in high and low FENDRR-expressing breast cancer tissues. (D) Real-time PCR analysis of FENDRR expression in five breast cancer cell lines. The error bars represent the standard deviation.

Abbreviation: PCR, polymerase chain reaction.
