| Cancer Name | breast cancer |
| ICD-0-3 | C50 |
| Methods | qPCR, ChIP, Luciferase reporter assay etc. |
| Sample | primary breast tumor tissues, cell lines (MCF-7, T47D, BT474, MDA-MB-468, MDA-MB-231, ZR-75-1 etc.) |
| Expression Pattern | up-regulated |
| Function Description | We show that expression of HOTAIR is regulated by B-catenin through a LEF1/TCF4-binding site. The dual treatment blocks nuclear expression of B-catenin and prevents its recruitment to the HOTAIR promoter. Consistently, forced expression of B-catenin rescued HOTAIR expression and cell viability in the presence of both drugs. Upregulation of HOTAIR is associated with TNBC in cell lines and a cohort of primary tumors. |
