| Cancer Name | lung adenocarcinoma |
| ICD-0-3 | C34 M8140/3 |
| Methods | qPCR, Western blot, RNAi, Luciferase reporter assays etc. |
| Sample | lung adenocarcinoma tissues, cell lines (A549, A549/DDP ) |
| Expression Pattern | up-regulated |
| Function Description | LncRNA XIST expression was markedly increased in cisplatin-resistant A549/DDP cells compared with parental A549 cells as shown by qRT-PCR. LncRNA XIST overexpression in A549 cells increased their chemosensitivity to cisplatin both in vitro and in vivo by protecting cells from apoptosis and promoting cell proliferation. We revealed that XIST functioned as competing endogenous RNA to repress let-7i, which controlled its down-stream target BAG-1. We proposed that XIST was responsible for cisplatin resistance of LAD cells and XIST exerted its function through the let-7i/BAG-1 axis. |
