Cancer&Entry Information
| Cancer Name | breast cancer |
| ICD-0-3 | C50 |
| Methods | Microarray, qPCR, RNAi etc. |
| Sample | cell lines (ZR-75-1, MCF7, BCAR4 etc.) |
| Expression Pattern | differential expression |
| Function Description | As BCAR4 expression in cell lines did not change the sensitivity to different chemotherapeutic agents, the increased sensitivity to lapatinib is not due to a general mechanism of drug resistance. Also in our BCAR4-expressing cell models, the combination of lapatinib and antioestrogens was more potent in inhibiting cell growth than lapatinib alone; indicating that blocking the ERBB2 pathway with lapatinib re-sensitises BCAR4-expressing cells to antioestrogens. BCAR4 expression strongly sensitised ZR-75-1 and MCF7 breast cancer cells to the combination of lapatinib and antioestrogens. |
