lncRNA EGOT is down‐regulated in breast cancer tissues and cell lines. (A) The relative EGOT level was measured in 50 paired breast cancer and adjacent tissues. (B) A Spearman’s correlation analysis of EGOT and Ki‐67 in 50 breast cancer tissues. (C) Relative EGOT levels were measured in breast cancer cell lines, including BT549, MDA‐MB‐231, MCF7 and SKBr3, and HEK293 was used as a control. Data shown are the mean ± SD for four independent experiments (n = 5) per cell line. Paired t‐test was performed for the comparison between two groups; linear regression analysis was performed to analyze the correlation between EGOT and Ki‐67. *P < 0.05; **P < 0.01 versus HEK293 cells.
