Cancer&Entry Information
| Cancer Name | breast cancer |
| ICD-0-3 | C50 |
| Methods | Microarray, qPCR, Western blot, RIP, luciferase reporter assay, Flow cytometry assay, etc. |
| Sample | human breast cancer cell line (MCF-7, MCF-7R). breast cancer tissues. |
| Expression Pattern | down-regulation |
| Function Description | Collectively, our study demonstrates that GAS5 enhances the efficacy of tamoxifen in the treatment of breast cancer and could be a novel prognostic biomarker. Tamoxifen is a frequently used drug for hormonal therapy in patients with breast cancer, however, development of resistance to tamoxifen remains a serious clinical problem.Kaplan-Meier survival analysis was used to analyze the relationship between the expression of GAS5 and survival rate. P < 0.05 indicates a significant difference. Moreover, GAS5 increased sensitivity of breast cancer cells to tamoxifen by serving as a molecular sponge for miR-222, contributing to suppression of phosphatase and tensin homologs (PTEN) (one endogenous target of miR-222). |
