Effects of the lncRNA NBR2 on the invasion and migration of breast cancer cells. (A) The healing ability of BT-549 and MDA-MB-231 breast cancer cells after knockdown or overexpression of the lncRNA NBR2 was evaluated by a scratch healing assay. (B) Transwell assays were used to detect the longitudinal migration and invasion ability of BT-549 and MDA-MB-231 breast cancer cells after knocking down or overexpressing the lncRNA NBR2. Each bar represents the mean ± SD of three independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001.
