High expression of TRIB3 is associated with poor prognosis in bladder cancer, positively correlated with stage and grade. Down-regulation of TRIB3 expression significantly inhibits growth, migration and cell cycle of bladder cancer cells.
Background Bladder cancer is a common malignant tumor characterized by high mortality and high management costs; however, it lacks useful molecular prognostic markers. Tribbles pseudokinase 3 (TRIB3) is a pseudokinase that participates in cell tumor progression and metabolism and whose function in bladder cancer is not precisely known. Main Methods We downloaded transcriptome data and clinical data of bladder cancer from associated databases and extracted the expression matrix of TRIB3 for multiple bioinformatics analysis. RT-PCR detected the expression of TRIB3 in bladder cancer cells. After knockdown of TRIB3 with siRNA, we investigated TRIB3 function using CCK8, Cell Cycle and Transwell assays. Key Findings Kaplan-Meier analysis of TRIB3 in the four cohorts showed that high expression of TRIB3 correlated with poor outcome. Expression of TRIB3 positively correlated with stage and grade and down-regulation of TRIB3 expression significantly inhibited proliferation, migration and cell cycle of bladder cancer cells. Significance TRIB3 is a potential prognostic marker and therapeutic target. It can be used to individualize the treatment of bladder cancer.
