Cancer&Entry Information
| Cancer Name | pancreatic cancer |
| ICD-0-3 | C25 |
| Methods | qPCR, RNAi, Western blot, RIP, Flow cytometry assay, Cell proliferation assay etc. |
| Sample | pancreatic cancer tissues, cell lines (CFPAC-1, SW1990, AsPC-1) |
| Expression Pattern | up-regulated |
| Function Description | And knockdown of MALAT-1 upregulated E-cadherin mRNA expression in pancreatic cancer cell lines. Therefore, we hypothesized that EZH2 might be recruited by MALAT-1 to synergistically repress E-cadherin. To test this hypothesis, we first asked whether MALAT-1 bound to EZH2 using a RNA Immunoprecipitation (RIP) assay. There was an average of 14- and 18- fold enrichment for MALAT-1 in the AsPC-1 and CFPAC-1 cells over-expressing EZH2, respectively, as compared to the IgG group. These results suggest that MALAT-1 is physically associated with the EZH2, and silencing EZH2 could increase E-cadherin transcription. |

| Title | EZH2 promotes cell migration and invasion but not alters cell proliferation by suppressing E-cadherin, partly through association with MALAT-1 in pancreatic cancer. |
