Long non-coding RNA BLACAT1 expression in breast cancer tissues. a BLACAT1 levels were higher in breast cancer tissues. 72 breast cancer tissues were prepared for RNA extraction. BLACAT1 expression was measured by real time RT-PCR. BLACAT1 expression in breast cancer tissues was compared to BLACAT1 expression in their compared normal tissues. b BLACAT1 expression was associated with breast cancer metastasis. The data was analyzed from BLACAT1 expression in metastatic tissues (n = 42) and non-metastatic tissues (n = 30). c BLACAT1 expression was associated with breast cancer tumor stage. The data was analyzed from BLACAT1 expression in different stage of tumor. d BLACAT1 expression was associated with the survival time of breast cancer patients. When the expression of BLACAT1 was more than twofold when comparing with its expression in adjacent normal tissues. Based on the statistical calculation, the fold changes of BLACAT1 expression in breast cancer tissues comparing to the expression of it in normal tissues more than twofold meant high BLACAT1 expression; less than 0.5-folds meant low BLACAT1 expression
