Cancer&Entry Information
| Cancer Name | glioma |
| ICD-0-3 | NA |
| Methods | qPCR, Luciferase reporter assay etc |
| Sample | glioma tissue,cell line(U251) |
| Expression Pattern | up-regulated |
| Function Description | We then suppressed HOTAIRM1 activity in the human glioblastoma U251 line using CRISPR-cas9 to knock in a truncating polyA fragment. Reporter analysis of these and control cells confirmed that the HOTAIRM1 locus serves as an active enhancer. We then performed Capture-C analysis to identify target genes of that locus and applied RNA antisense purification to assess chromatin interactions between the HOTAIRM1 locus and HOXA cluster genes. HOTAIRM1 knockdown in glioma cells decreased proliferation and reduced expression of HOXA cluster genes. |
