Cancer&Entry Information
| Cancer Name | ovarian cancer |
| ICD-0-3 | C56.9 |
| Methods | qPCR, Western blot, Luciferase reporter assay, RNAi, etc. |
| Sample | OC cells (CaOV3, SKOV3, OVCAR3, and OV90) and human ovarian epithelial cell line (HOSE) |
| Expression Pattern | up-regulated |
| Function Description | MALAT1 expression in OC cells was elevated compared with HOSE cells. MTT assay and EdU assay supported that si-MALAT1 could inhibit cell proliferation in OC cells. Treatment of si-MALAT1 results in increased cell apoptosis rate in both SKOV3 cells and OVCAR3 cells. The expression of lncRNA-MALAT1 was negatively associated with the expression of miR-503-5p in OC cells, while luciferase assay and RNA pull-down together supported the direct binding of MALAT1 with miR-503-5p. Knockdown of MALAT1 was able to inhibit the activation of JAK2/STAT3 signal pathway, and MALAT1 overexpression was accompanied by activation of these factors. |
