LncRNA ROR is highly expressed in breast cancer tissues. a The expression of lncRNA ROR in breast cancer tissues and adjacent tissues detected by RT-qPCR. b The expression of lncRNA ROR in normal mammary epithelial cell line MCF-10A and breast cancer cell lines MCF-7, SKBR3, BCAP and MDA-MB-231 determined by RT-qPCR. * p < 0.05 vs. the adjacent tissues. The above data are measurement data and expressed as mean ± standard deviation. Comparisons between two groups are analyzed by paired t test, and comparisons among multiple groups are analyzed by analysis of variance. Post hoc test was conducted using Tukey’s test. n = 60. The experiment is repeated 3 times. RT-qPCR, reverse transcription quantitative polymerase chain reaction; TIMP3, tissue inhibitors of metalloproteinase 3; n, number
