Cancer&Entry Information
| Cancer Name | glioblastoma multiforme |
| ICD-0-3 | NA |
| Methods | qPCR, RNAi, other |
| Sample | GBM tissues and cell lines (U87, U251, and A172) |
| Expression Pattern | up-regulated |
| Function Description | HOTAIRM1 silencing caused tumor suppressive effects via inhibiting cell proliferation, migration and invasion, and inducing cell apoptosis. In vivo experiments showed knockdown of HOTAIRM1 lessened the tumor growth. Additionally, HOTAIRM1 action as regulating the expression of the HOXA1 gene. HOXA1, as an oncogene, it's expression levels were markedly elevated in GBM tissues and cell lines. Mechanistically, HOTAIRM1 mediated demethylation of histone H3K9 and H3K27 and reduced DNA methylation levels by sequester epigenetic modifiers G9a and EZH2, which are H3K9me2 and H3K27me3 specific histone methyltransferases, and DNA methyltransferases (DnmTs) away from the TSS of HOXA1 gene. |
