Cancer&Entry Information
| Cancer Name | hepatocellular carcinoma |
| ICD-0-3 | C22.0 |
| Methods | qPCR, Western blot, Luciferase reporter assay, RIP etc |
| Sample | HCC and corresponding non-tumor liver tissues , cell lines (HepG2, SMMC-7721) |
| Expression Pattern | up-regulated |
| Function Description | Here, we demonstrated that MALAT1 expression was obviously high in sorafenib-resistant HCC cells. Furthermore, knockdown of MALAT1 increased sorafenib sensitivity in nonresponsive HCC cells, whereas forced expression of MALAT1 conferred sorafenib resistance to responsive HCC cells in vitro In addition, loss/gain-of-function assays revealed that MALAT1 promoted cell proliferation, migration, and epithelial-mesenchymal transition in HCC cells. Mechanistically, MALAT1 regulated Aurora-A expression by sponging miR-140-5p, thus promoting sorafenib resistance in HCC cells. |
