Cancer&Entry Information
| Cancer Name | intrahepatic cholangiocarcinoma |
| ICD-0-3 | C22 |
| Methods | qPCR, Western blot, Luciferase Reporter Assays etc. |
| Sample | cell lines (HCCC-9810, HUCCT1, QBC-939, RBE) |
| Expression Pattern | up-regulated |
| Function Description | CCAT1 expression was elevated in ICC tissues compared to the adjacent normal tissues. We also found that high CCAT1 expression is closely correlated with tumor progression in ICC patients. Furthermore, our results show that knockdown of CCAT1 significantly suppressed the migration and invasion of ICC cells. Additionally, CCAT1 silencing remarkably reverses the EMT phenotype of ICC cells. Moreover, bioinformatics analysis and luciferase reporter assay revealed that CCAT1 directly bound to the miR-152, which has been reported to serve as a tumor suppressor in variety cancers. Further investigation demonstrated that CCAT1 led to the metastasis and EMT activation of ICC cells through inhibiting miR-152. |
