Abstract
Objectives
The aim of this study was to investigate the effect of lncRNA-SNHG15 in bladder carcinoma using cell lines experiments and the relationship between clinical characteristics and lncRNA-SNHG15 expression was analyzed.
Methods
Bladder cancer tissues and near-cancer tissues were collected. The real-time PCR (RT-PCR) was used to detect the expression of lncRNA-SNHG15 in tissues and cell lines. The expression of lncRNA-SNHG15 was downregulated by interference (siRNA), as detected by RT-PCR, that was used to determine the efficiency of the interference. CCK-8 and Transwell assays were used to evaluate the effect of lncRNA-SNHG15 on the proliferation and invasion capability of bladder cancer cells. The t-test was used for Statistical analyses, which were carried out using the Statistical Graph pad 8.0.1.224 software.
Result
The expression of lncRNA-SNHG15 was up regulated in 5637, UMUC3 and T24 cell lines compared with corresponding normal controls (P < 0.05). Up regulation was positively related to tumor stage (P = 0.015). And tumor size (P = 0.0465). The down-regulation of lncRNA-SNHG15 with siRNA significantly inhibited UMUC3 and T24 cell proliferation and invasion.
Conclusion
This study showed that lncRNA-SNHG15 is overexpressed in bladder cancer tissues and (5637, UMUC3 T24) cell lines. Up regulation was positively related to tumor stage (P = 0.015), and tumor size (P = 0.0465). Down-regulation of lncRNA-SNHG15 by siRNA significantly inhibited UMUC3 and T24 cell proliferation and invasion, indicating a potential molecular target for future tumor targeted therapy.
