| Disease Name: | Colorectal Neoplasms |
| Sample: | CRC tissues and cancer cells |
| Dysfunction Pattern: | Interaction( miR-581/EDEM1 axis) |
| Validated Method: | qRT-PCR//Colony Formation Assay//Western Blot |
| Description: | We found that LINC00485 expression was significantly lower in CRC tissues and cancer cells than in paired normal samples and human normal colonic epithelial cells.MicroRNA miR-581 was the downstream target of LINC00485, which was downregulated in CRC samples and cancer cells compared to normal tissues and normal colonic epithelial cells. MiR-581 overexpression induced proliferation, migration, and invasion of FHC cells, while miR-581 antagomir treatment produced opposite results. MiR-581 directly targeted the 3'UTR of EDEM1 and inhibited its expression and induction of epithelial-mesenchymal transition of CRC. |
| Causality: | Yes |
| Causal Description: | In mouse models, LINC00485 knockdown or down-regulation of miR-581 significantly repressed CRC cell growth and prevented CRC liver metastasis. LINC00485 knockdown promoted the proliferation, migration, and invasion of FHC cells, while LINC00485 overexpression weakened these abilities of LoVo cells. |
| Clinical-realted Application: | Lower expression of LINC00485 predicted poor prognosis in CRC patients. |
