| Cancer Name | breast cancer |
| ICD-0-3 | C50 |
| Methods | qPCR, Western blot, Luciferase reporter assay etc. |
| Sample | breast cancer tissues, cell lines (MCF-7, ZR-75-1, HCC-1937, MDA-MB-231, MDA-MB-468 and MDA-MB-453) |
| Expression Pattern | up-regulated |
| Function Description | XIST was significantly down-regulated in breast cancer tissues and cell lines. Further functional analysis indicated that overexpression of XIST remarkably inhibited breast cancer cell growth, migration, and invasion.The results of luciferase reporter assays verified that miR-155 was a direct target of XIST in breast cancer. Moreover, caudal-type homeobox 1 (CDX1) was identified as a direct target of miR-155 and miR-155/CDX1 rescued the effects of XIST in breast cancer cells. Taken together,XIST is down-regulated in breast cancer and suppresses breast cancer cell growth, migration, and invasion via the miR-155/CDX1 axis. |
