Cancer&Entry Information
| Cancer Name | glioma |
| ICD-0-3 | NA |
| Methods | qPCR, Western blot etc. |
| Sample | glioma tissues, cell lines (U-251, M059J) |
| Expression Pattern | up-regulated |
| Function Description | MEG3 was then overexpressed by ligating to a lentiviral vector.Overexpressed MEG3 inhibited the proliferation of U-251 cells, and restrained the expression of proliferation marker proteins Ki67 and proliferating cell nuclear antigen (PCNA). However, cell apoptosis rate of U-251 cells and the expression of apoptosis marker proteins were elevated by MEG3. Furthermore, miR-93 was predicted a direct target of lncRNA-MEG3 by bioinformatics analysis. Overexpressed MEG3 counteracted the role of miR-93 in facilitating proliferation and inhibiting apoptosis in U-251 cells. Moreover, MEG3 restained the activation of phosphatidylinositol 3 kinase/protein kinase B (PI3K/AKT) pathway by reducing cytomembrane translocation of AKT. |
