Cancer&Entry Information
| Cancer Name | nasopharyngeal cancer |
| ICD-0-3 | C11 |
| Methods | qPCR, RNAi, Western blot etc. |
| Sample | NPC tissues, cell lines (CNE2, HNE2) |
| Expression Pattern | down-regulated |
| Function Description | We found that lncRNA-LET was significantly downregulated in nasopharyngeal carcinoma (NPC) tissues compared with corresponding normal tissues. Decreased LET expression is significantly correlated with advanced clinical stage, larger tumor size, increased lymph node tumor burden, and poor survival of NPC patients. Knockdown of LET promoted NPC cells proliferation and inhibited cell apoptosis. Importantly, we found lncRNA-LET is transcriptional repressed by EZH2-mediated H3K27 histone methylation on the LET promoter. The expressions of EZH2 and lncRNA-LET are significantly inversely correlated in NPC tissues. |
