Cancer&Entry Information
| Cancer Name | breast cancer |
| ICD-0-3 | C50 |
| Methods | qPCR, Western blot, ChIP, Luciferase reporter assay etc. |
| Sample | cell lines (MCF7 and T47D) |
| Expression Pattern | differential expression |
| Function Description | We found that, when the RhoC-ROCK signaling was disturbed by specific siRNAs or chemical inhibitors, the expression of HOTAIR would be down-regulated. Further, MRTF-A and SRF were found to affect HOTAIR expression. HOTAIR promoter activity was demonstrated to be regulated by the RhoC-MRTF-A-SRF signaling in a CArG-box-dependent manner. Moreover, MRTF-A was identified to physically interact with HOTAIR promoter, and RNA polymerase II association on HOTAIR promoter was enhanced by MRTF-A overexpression. |
