Cancer&Entry Information
| Cancer Name | gastric cancer |
| ICD-0-3 | C16 |
| Methods | qPCR, RNAi, Western blot, Luciferase reporter assay, Flow cytometry assay etc. |
| Sample | gastric cancer tissues, cell lines (SGC-7901 and BGC-823) |
| Expression Pattern | up-regulated |
| Function Description | HOTAIR was significantly upregulated in cisplatin-resistant gastric cancer cells and tissues compared with control cells and noncancerous gastric tissues. Overexpression of HOTAIR enhanced gastric cancer cell proliferation, promoted cell cycle G1/S transition, but decreased tumor cell apoptosis. Furthermore, HOTAIR was shown to directly bind to and inhibit miR-126 expression and then to promote VEGFA and PIK3R2 expression and activate the PI3K/AKT/MRP1 pathway. |
| Pubmed ID | 27900563 |
| Year | 2016 |
| Title | LncRNA HOTAIR promotes cisplatin resistance in gastric cancer by targeting miR-126 to activate the PI3K/AKT/MRP1 genes. |
