| Cancer Name | breast cancer |
| ICD-0-3 | C50 |
| Methods | qPCR, RNAi, IHC, ISH etc. |
| Sample | cell lines (M10, MCF10A, MCF7, MDA-MB-468, MDA-MB-231 and Hs578T) |
| Expression Pattern | down-regulated |
| Function Description | Here, we show that Xist expression is significantly reduced in breast tumor samples and cancer cell lines. Xist knockdown or overexpression resulted in increased or decreased levels, respectively, of AKT phosphorylation and cell viability. Further studies revealed an inverse correlation between Xist and phospho-AKT levels in breast cancer samples. Additionally, Xist knockdown-elicited increase of cell viability was attenuated by AKT inhibitor. These results suggest that Xist negatively regulates cell viability via inhibition of AKT activation. |
