Cancer&Entry Information
| Cancer Name | esophageal squamous cell carcinoma |
| ICD-0-3 | NA |
| Methods | qPCR, Western blot, Luciferase reporter assay, RIP, etc. |
| Sample | ESCC tissues, Human immortalized esophageal epithelial cell line HET-1A and human ESCC cell lines (ECA109 and EC9706) |
| Expression Pattern | up-regulated |
| Function Description | TUG1 was up-regulated in DDP-resistant ESCC tissues and cells. High TUG1 expression was correlated with poor prognosis of ESCC patients. TUG1 knockdown improved the sensitivity of ECA109/ DDP and EC9706/DDP cells to DDP. Moreover, TUG1 could epigenetically suppress PDCD4 expression via recruiting enhancer of zeste homolog 2. PDCD4 overexpression could mimic the functional role of down-regulated TUG1 in DDP resistance. PDCD4 knockdown counteracted the inductive efect of TUG1 inhibition on DDP sensitivity of ECA109/DDP and EC9706/DDP cells. Furthermore, TUG1 knockdown facilitated DDP sensitivity of DDP-resistant ESCC cells in vivo. |
