Cancer&Entry Information
| Cancer Name | gastric cancer |
| ICD-0-3 | C16 |
| Methods | qPCR, Western blot etc. |
| Sample | gastric cancer tissues, cell line (GES-1) |
| Expression Pattern | down-regulated |
| Function Description | We found that expression of both miR-141 and MEG3 was significantly reduced in GC compared with levels in matched nonmalignant tissues. Positive correlation between miR-141 and MEG3 was found in both tumor tissues and control tissues. Furthermore, the over-expression of either miR-141 or MEG3 in 7901 and MKN45 cells inhibited cell proliferation and cell cycle progression and promoted cell apoptosis. E2F3 was identified as a target of miR-141, and its inhibition significantly reduced MEG3 expression. E2F3 over-expression partly reversed the changes caused by transfection of miR-141 mimic, and inhibition of miR-141 or MEG3 overrides MEG3- or miR-141-induced modulation of cell growth in GC. |
