Cancer&Entry Information
| Cancer Name | colorectal cancer |
| ICD-0-3 | C19.9 |
| Methods | RT-qPCR, Western blot analysis, Dual Luciferase Reporter Assay |
| Sample | CRC and pair-matched normal tissues,CRC cell lines (SW480, SW620, HT29, HCT116) and human normal colon epithelial cell (FHC) |
| Expression Pattern | up-regulated |
| Function Description | a significant increase of TTN-AS1 expression level in CRC tissues and cell lines compared with normal counterparts. High expression of TTN-AS1 predicted a poor prognosis and was correlated with aggressive clinicopathological characteristics in CRC patients. Functionally, gain- and loss-of-function studies indicated that TTN-AS1 knockdown suppressed the proliferation, migration, invasion and epithelial-mesenchymal transition of CRC cells in vitro, whereas TTN-AS1 overexpression showed the complete opposite effects. Mechanistically, we found that TTN-AS1 could directly interact with miR-497, and co-transfection with miR-497 mimics blocked the activation of PI3K/Akt/mTOR signaling, and reversed the effects of TTN-AS1 overexpression in CRC cells. |
