Cancer&Entry Information
| Cancer Name | breast cancer |
| ICD-0-3 | C50 |
| Methods | qPCR, Luciferase reporter assay, RIP |
| Sample | Breast cancer tissues, human breast cancer cell lines (MCF-7 and MDA-MB-231) |
| Expression Pattern | up-regulated |
| Function Description | CCAT1 was up-regulated and miR-148b was down-regulated in radioresistant breast cancer tissues compared with radiosensitive breast cancer tissues.CCAT1 down-regulation reduced colony formation rates and caspase3 activity in breast cancer cells under irradiation. Moreover, CCAT1 could negatively regulate miR-148b expression. Furthermore, overexpression of miR-148b suppressed colony survival fraction and caspase3 expression under irradiation in breast cancer cells, which was exacerbated by CCAT1 knockdown. |

| Title | Down-regulation of LncRNA CCAT1 enhances radiosensitivity via regulating miR-148b in breast cancer. |
