The expression level of LINC01133, ZEB1-AS1 and ABHD11-AS1 was altered in luminal BC tissues and cell lines compared to adjacent non-tumoral tissues and a normal breast cell line. The lncRNAs expression levels were detected by qRT-PCR in tumoral and non-tumoral tissues from 79 patients. A, B LINC01133 was significantly downregulated in luminal BC tissues (64% of cases). C, D ZEB1-AS1 (T5,6) was significantly downregulated in luminal BC tissues (80% of cases). E, F ZEB1-AS1 (T1-4) was significantly downregulated in luminal BC tissues (71% of cases). G, H ABHD11-AS1 was significantly upregulated in luminal BC tissues (70% of cases). All PCR reactions were performed three times and compared by paired sample t-test. B2M was used as an internal control. Data was presented as the mean ± SD. (***p < 0.001; **p < 0.01)
