Cancer&Entry Information
| Cancer Name | multiple myeloma |
| ICD-0-3 | C42.1 |
| Methods | qPCR, Luciferase reporter assays, Western blot, RIP etc. |
| Sample | cell lines (MM.1S, OPM-2, NCI-H929, U266, RPMI-8226) |
| Expression Pattern | up-regulated |
| Function Description | MALAT1 expression was upregulated in MM samples and cell lines. In function assays, we confirmed that MALAT1 inhibition significantly suppressed cells proliferation, induced cells apoptosis, arrested cells in G1/S phase, and inhibited MM cells growth in vivo. Furthermore, MALAT1 was identified to function as a competitive endogenous RNA (ceRNA) for miR-509-5p to promote MM cell viability. Additionally, our results suggested that miR-509-5p targeted the 3??UTR of FOXP1 to suppress MM cells progression. Meanwhile, our results showed that miR-509-5p inhibitors significantly abrogated the decreased expression of FOXP1 induced by MALAT1 suppression, indicating that MALAT1 could positively regulate FOXP1 expression by sponging miR-509-5p. |
