Cancer&Entry Information
| Cancer Name | cervical cancer |
| ICD-0-3 | C53 |
| Methods | qPCR, RNAi, Western blot etc. |
| Sample | cervical cancer tissues, cell lines (HeLa, CaSki) |
| Expression Pattern | down-regulated |
| Function Description | We observed that MEG3 was downregulated in cervical cancer tissues, compared to the adjacent normal tissues, and was negatively related with FIGO stages, tumor size, lymphatic metastasis, HR-HPV infection and the expression of homo sapiens microRNA-21 (miR-21). Furthermore, we focused on the function and molecular mechanism of MEG3, finding that overexpression of MEG3 reduced the level of miR-21-5p expression, causing inhibition of proliferation and increased apoptosis in cervical cancer cells. In summary, our findings indicate that MEG3 function as a tumor suppressor by regulating miR-21-5p, resulting in the inhibition of tumor growth in cervical cancer. |
