Cancer&Entry Information
| Cancer Name | esophageal squamous cell carcinoma |
| ICD-0-3 | NA |
| Methods | qPCR, Western blot, RIP, Luciferase reporter assay, Cell proliferation assay etc. |
| Sample | ESCC tissues, cell lines (KYSE30, KYSE140, KYSE150, KYSE180, KYSE410, and KYSE510) |
| Expression Pattern | up-regulated |
| Function Description | We found that HOTAIR was aberrantly upregulated in ESCC cells and that HOTAIR depletion inhibited proliferation and led to G1 cell cycle arrest in ESCC cells. Besides, we found that HOTAIR acted as an endogenous sponge to downregulate miR-1 expression by directly binding to miR-1. Furthermore, HOTAIR overturned the effect of miR-1 on the proliferation and cell cycle profile in ESCC cells, which involved the derepression of cyclin D1 (CCND1) expression, a target of miR-1. Taken together, our study elucidated a novel HOTAIR /miR-1/CCND1 regulatory axis in which HOTAIR acted as a competing endogenous RNA by sponging miR-1 and upregulated CCND1 expression, thereby facilitating the tumorigenesis of ESCC. |
