Abstract
- Renal cell carcinoma (RCC) is a type of urinary tumor with a high incidence and is often associated with tumor metastasis. Long non-coding RNA (lncRNA) regulates tumorigenesis, progression, and metastasis. However, the role and the predictive value of lncRNA in RCC progression and metastasis have not been elucidated. The purpose of this study was to evaluate the effect of a newly discovered lncRNA LOC648987 on RCC proliferation and metastasis. LOC648987 was identified by RT-PCR for high expression in human RCC tissues as well as in metastatic RCC tissues. In the cell experiments, we infected the RCC cell lines ACHN and 786-O cells with LOC648987-shRNA and its negative control (shNC). The results showed that the knockdown of LOC648987 inhibited the proliferation of ACHN and 786-O cells and colony formation. The cell cycle and the apoptosis progression of ACHN and 786-O cells were assessed using flow cytometry. The knockdown of LOC648987 significantly inhibited the progression of ACHN and 786-O cells from G0/G1 to S phase and promoted cell apoptosis. The metastasis promoting effects of LOC648987 on ACHN and 786-O cells were verified by transwell migration assays, which depended on vimentin and MMP-9 to regulate the epithelial–mesenchymal transition. Finally, the promotion of LOC648987 on RCC tumorigenesis was evaluated in BALb/c nude mice. These data confirmed that lncRNA LOC648987 promoted RCC cell proliferation and tumor metastasis and regulated the expression of EMT-related proteins in RCC cells.
