To better understand its role in the context of breast cancer resistance, the authors found that upregulation of lncRNA-ROR in tamoxifen resistant MCF7/TR5 and MDA-MB-231 breast cancer cells inhibited the expression of miR-205-5p, and increased ZEB1/2 gene expression, thereby enhancing the EMT process (Figure 2). The gene discussed is ZEB1; the disease is breast carcinoma.
