drug basic information
Drug ID:
DB00675 (APRD00123)
Drug Name:
Tamoxifen
Drug Method:
Breast epithelial (MCF10A), breast cancer (MCF7), and natural tamoxifen-resistant breast cancer (MDA-MB-231) cell lines were selected, and the relative lncRNA-ROR expressions were detected using quantitative real-time polymerase chain reaction (qRT-PCR). In vitro induction of TR5 cell line was performed. There were six groups: MCF7, MCF7/TR5, MDA-MB-231, MCF7-ROR, MCF7/TR5 ROR-siRNA, and the MDA-MB-231 ROR-siRNA groups. CCK-8 assay was conducted to assess the changes in drug resistance of each group. The expression of the epithelial mesenchymal transition (EMT) marker was detected using Western blotting. Transwell was selected to test the invasive ability of the cells. Expressions of microRNA-205 (miR-205) and ZEB1/2 were detected using qRT-PCR .
