Cancer&Entry Information
| Cancer Name | glioblastoma |
| ICD-0-3 | NA |
| Methods | qRT-PCR, Western blotting, in vitro knockdown, RIP etc. |
| Sample | human GBM cell lines (U87, LN229, A172, T98, U251) and human embryonic kidney (HEK) 293 T cells ,GBM cell Exosomes |
| Expression Pattern | up-regulated |
| Function Description | SBF2-AS1 was upregulated in TMZ-resistant GBM cells and tissues, and overexpression of SBF2-AS1 led to the promotion of TMZ resistance, whereas its inhibition sensitized resistant GBM cells to TMZ. Transcription factor ZEB1 was found to directly bind to the SBF2-AS1 promoter region to regulate SBF2-AS1 level and affected TMZ resistance in GBM cells. SBF2-AS1 functions as a ceRNA for miR-151a-3p, leading to the disinhibition of its endogenous target, X-ray repair cross complementing 4 (XRCC4), which enhances DSB repair in GBM cells. Exosomes selected from temozolomide-resistant GBM cells had high levels of SBF2-AS1 and spread TMZ resistance to chemoresponsive GBM cells. Clinically, high levels of lncSBF2-AS1 in serum exosomes were associated with poor response to TMZ treatment in GBM patients. |
