Topotecan hydrochloride (trade name Hycamtin) is a potent antineoplastic agent. It is a water soluble analog of the alkaloid camptothecin that potently inhibits DNA topoisomerase I. Topotecan hydrochloride induces rapid apoptotic death in human B-lineage acute lymphoblastic leukemia (ALL) cells with IC50 values of 33 nM and 0.28 μM, respectively. Topotecan improves survival in three mouse models of poor prognosis ALL and downregulates B-Myb and MycN expression in neuroblastoma cells. Topotecan demonstrates a broad spectrum of antitumor activity against a variety of other tumors including ovarian cancer, cervical cancer, neuroblastoma, brainstem glioma, and Ewing’s sarcoma.

| Method | CCK8 Assay and ABCG2 ATPase assay | |
| Cell Lines | RCSC cells | |
| Concentrations | 0~10 μM | |
| Incubation Time | 72 h | |
| Results | MiR-3163 plays important roles in multidrug resistance (Table 1, Fig. 5A). Results showed that when miR-3163 was overexpressed in RCSCs, the ATPase activity of ABCG2 was significantly downregulated compared to RCSCs with Scramble (Fig. 5B). |
