Cancer&Entry Information
| Cancer Name | head and neck squamous cell carcinoma |
| ICD-0-3 | C76.0 |
| Methods | qPCR, Western blot, Flow cytometry assay etc. |
| Sample | cell lines (Tca8113, Tca8113P160, Tb3.1) |
| Expression Pattern | differential expression |
| Function Description | We employed a HOTAIR specific siRNA to deplete its expression in two human HNSCC cell lines, Tca8113 and Tscca. The flow cytometry (FCM) analysis showed that HOTAIR depletion induced tumor cell apoptosis in vitro. JC-1 probe examination showed that the mitochondrial membrane potential was changed significantly by HOTAIR blockage. Mitochondrial calcium uptake 1(MICU1) dependent cell death was induced by HOTAIR depletion. Protein expression analysis indicated that mitochondrial related cell death pathway (Bcl-2, BAX, Caspase-3, Cleaved Caspase-3, Cytochrome c) involved in HOTAIR dependent apoptosis process. Moreover, a Tscca derived xenograft tumor model was employed to further validate that injection of HOTAIR siRNA inhibited tumor growth. |
