drug basic information
Drug ID: DB00997 (APRD00185, DB05331, DB05847)
Drug Name: Doxorubicin
Drug Method: Quantitative Real-time poly chain reaction (qRT-PCR) was employed to detect the expression level of miR-574 in breast cancer Dox-resistant MCF-7/Adr cell line and parental MCF-7 cell line. Using miR-574 mimics and inhibitors, miR-574 level was up- or down- regulated. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was handled to detect the IC50, and flow cytometric analysis was employed to measure the apoptosis and cell circle. Dual-luciferase and Western-blot experiments were applied to verify the direct target gene of miR-574.
Drug Response: resistant
Cancer basic information
Cancer: breast cancer
Tissue/Cell: cell line (MCF-7,MCF-7/Adr)
