Cancer&Entry Information
| Cancer Name | chondrosarcoma |
| ICD-0-3 | NA |
| Methods | qPCR, RNAi, Western blot, Luciferase reporter assay, CCK-8 assay etc. |
| Sample | chondrosarcoma tissues, cell lines (HC-a, SW1353, OUMS-27, HCS-2/8, JJ012) |
| Expression Pattern | up-regulated |
| Function Description | HOTAIR expression was upregulated in chondrosarcoma tissues and cell lines. Functional experiments reveal that HOTAIR knockdown leads to growth inhibition of human chondrosarcoma cells in vitro and in vivo. In addition to cycle arrest and apoptosis, knockdown of HOTAIR inhibits autophagy, which favors cell death. Mechanistically, we demonstrated that HOTAIR induced DNA methylation of miR-454-3p by recruiting EZH2 and DNMT1 to the miR-454-3p promoter regions,which markedly silences miR-454-3p expression. Further analysis revealed that STAT3 and ATG12 are targets of miR-454-3p,initiate HOTAIR deficiency-induced apoptosis and reduce autophagy. |
