Cancer&Entry Information
| Cancer Name | bladder cancer |
| ICD-0-3 | C67 |
| Methods | qPCR, Western blot, in vitro knockdown, etc. |
| Sample | bladder cancer tissues, Bladder cancer cell lines (T24, 5637, and SW780) and normal bladder cell line SV-HUC-1 |
| Expression Pattern | down-regulated |
| Function Description | The expression of MIR503HG was downregulated in bladder cancer tissues and cell lines. Low expression of MIR503HG was associated with advanced tumor stage, advanced histological grade, and lymph node metastasis. Ectopic expression of MIR503HG inhibited cell proliferation, cell growth, cell invasion, and migration, and also promoted cell apoptosis and inhibited cell cycle progression in SW780 cells. In parallel, T24 cells were used for loss of function studies. Knockdown of MIR503HG promoted the cancer cell proliferation and increased the migration and invasion abilities of T24 cells. In addition, knockdown of MIR503HG reduced the cell apoptotic rate in cancer cells and promoted cell cycle progression. Furthermore, MIR503HG overexpression decreased the epithelial mesenchymal transition related mRNA and protein levels of ZEB1, Snail, N cadherin, and vimentin, with an increase in E cadherin level. Consistently, knockdown of MIR503HG showed the opposite effects. In vivo xenograft, nude mice results showed that overexpression of MIR503HG suppressed the tumor growth and tumor metastasis. In conclusion, our results identified a novel lncRNA MIR503HG that exhibited significant antiproliferation, antimigration/invasion effects on bladder cancer cells both in vitro and in vivo, which may hold a therapeutic promise to treat bladder cancer. |
