Cancer&Entry Information
| Cancer Name | breast cancer |
| ICD-0-3 | C50 |
| Methods | qPCR etc. |
| Sample | cell lines (MCF-7/TR and T47D/TR) |
| Expression Pattern | up-regulated |
| Function Description | Our findings showed that BLACAT1 was significantly upregulated in TAM-resistant BCa cells (MCF-7/TR and T47D/TR), and BLACAT1 knockdown markedly reduced the TAM resistance in these cells. Importantly, we observed that BLACAT1 might function as a competing endogenous RNA of miR-503 in MCF-7/TR and T47D/TR cells, thereby increasing the expression of oncogenic Bcl-2 protein. Rescue experiments showed that miR-503 inhibition partly blocked the inhibitory effect of BLACAT1 knockdown on TAM resistance of MCF-7/TR and T47D/TR cells. |
