Cancer&Entry Information
| Cancer Name | melanoma |
| ICD-0-3 | NA |
| Methods | RT-qPCR, Western blot analysis etc. |

| Expression Pattern | up-regulated |
| Function Description | We demonstrated that miR-34a is negatively correlated with MALAT1 in melanoma cells and tumor specimens. Interestingly, MALAT1, which contains functional sequence-specific miR-34a-binding sites, regulates miR-34a stability in melanoma cells and in vivo. Importantly, MALAT1 was significantly enriched in the Ago2 complex, but not when the MALAT1-binding site of miR-34a was mutated. Furthermore, MALAT1 could be shown to regulate c-Myc and Met expression by functioning as a miR-34a sponge. |
